I was having this question and found the same one in a previous post https://github.com/axiomatic-systems/Bento4/issues/489 but there was no answer, probably cause the issue was set to "close" previously.

I'm trying to extract the HEVC elementary stream from a DASH/HLS fMP4 segment so I can inspect it using https://github.com/virinext/hevcesbrowser for debugging purposes.
For this I need to extract the payload of the `mdat` box of the segment. But it looks like that `mp42hevc` is not capable of doing this?
```
mp42hevc 1.m4s 1.hevc
ERROR: no movie in file
```
What do you think, could this feature be added?
I also tried
```
mp4extract --payload-only mdat 1.m4s mdat1.hevc
```
with no luck. The resulting `mdat1.hevc` is not readable.
Do you have an idea for how to extract the HEVC stream in this scenario?

] | Hi there,
I found a heap-buffer-overflow in `mp42aac` with a fuzzer.
- Bento4 version: v1.6.0-639 (commit 5abeaa0ebdb8c3be5b710517eb04d807832d2bbf)
- Compiler args: DCMAKE_C_FLAGS=-fsanitize=address
- Platform: Ubuntu 20.04.2 LTS, x86_64
- Reproduce: `mp42aac heap_Ap4HvccAtom_poc /dev/null`
- POC: [heap_Ap4HvccAtom_poc.tar.gz](https://github.com/axiomatic-systems/Bento4/files/6908277/heap_Ap4HvccAtom_poc.tar.gz) (decompress it first)

"axiomatic-systems",

] | I am trying to generate and play a HLS stream in HEVC codec using bento4's `mp4hls` command. The issue is that when I upload the stream on S3, it is not playing on Safari (Note: stream is not working/playing from local as well).
Since HEVC has added benefits, I prefer keeping the codec to h265 only.
Another point to note here is that I manually converted the `mp4` file from `h264` to `h265`. If there's a way to achieve the above config without generating an intermediate h265 mp4, I'll be happy to use that as well.
Command used:
```
mp4hls original.mp4 --hls-version=7 --master-playlist=playlist --media-playlist-name=temp
```
ffprobe of the file is

] | The `--hls-media-playlist-name` and `--hls-iframes-playlist-name` params don't appear to be used to name the playlist files when executing `mp4dash --hls`. From looking through the code it seems like they are only used conditionally (and the condition is when they aren't set or if `options.on_demand` is true - https://github.com/axiomatic-systems/Bento4/blob/4f813a9b791e312761b762fcab4b09e921bee584/Source/Python/utils/mp4-dash.py#L939).
The `--hls-master-playlist-name` is working as expected.
Is there a reason these can't be used all of the time? Also, is it possible to have a param for the audio playlist as well?
It would be nice to be able to generate predictable playlist names when running bento4 in an automated environment.
Incase I'm misinterpreting what those params are supposed to be doing, what I'm asking for is a way to name the `.m3u8` playlists that are generated in the output directory, currently what I'm seeing for `hevc` content is the following:
`video-hvc1.m3u8` (assuming this is the media playlist)
`video-hvc1_iframes.m3u8` (assuming this is the iframes playlist)
`master.m3u8` (master playlist)
`audio-en-mp4a.40.2.m3u8` (would like to also be able to rename the audio playlist) | mp4dash `--hls-media-playlist-name` and similar params not respected | https://api.github.com/repos/axiomatic-systems/Bento4/issues/624/comments | 2 | 2021-07-21T18:09:30Z | 2021-07-26T14:04:54Z | https://github.com/axiomatic-systems/Bento4/issues/624 | 949,972,106 | 624 |

I manage to build bento4 on Xcode without any issue (thank you for the great work!)
Question, is there an easy way after build to deploy into /Applications or another directory or do I have to manually move all Python scripts and binaries into my own directory hierarchies?

`mp42hls --index-filename /outpath/media.m3u8 --segment-filename-template /outpath/encrypt/audio/aac/kin/segment-%d.ts --segment-url-template segment-%d.ts --show-info --hls-version 4 --iframe-index-filename /outpath/encrypt/audio/aac/kin/iframes.m3u8 --audio-format ts --encryption-mode AES-128 --encryption-key KEY --encryption-iv-mode random --encryption-key-uri http://example.com --audio-track-id 1 --video-track-id 0 /inpath/fmp4/audiofile.mp4`
I keep getting this error: **Exception: binary tool failed with error -11 -**
If I remove the show-info argument and add --verbose, I don't get the error and everything works. The issue I have doing that, is I call this from the mp4-hls.py script. That turns on show-info by default and removing that argument I get another error.
So my question is, what do I do to fix this? | mp42hls Segmentation Error -11 | https://api.github.com/repos/axiomatic-systems/Bento4/issues/619/comments | 0 | 2021-06-28T20:55:36Z | 2021-06-30T20:53:09Z | https://github.com/axiomatic-systems/Bento4/issues/619 | 931,984,669 | 619 |

ffmpeg -y -i SOURCE -map 0:a:0 -ac 2 -c:a aac -b:a 128k -movflags default_base_moof+empty_moov+faststart -map_metadata -1 -frag_duration 2000000 -f mp4 TRANSCODED.mp4
```
And then feed it into mp4dash:
```
mp4dash --no-split --force --hls --hls-master-playlist-name=gYFzjPBgaRg_master.m3u8 --hls-media-playlist-name=gYFzjPBgaRg.m3u8 --encryption-cenc-scheme=cbcs --encryption-key=KID:KEY:IV --eme-signaling=pssh-v1 --widevine --widevine-header="provider:intertrust#content_id:2a" ./TRANSCODED.mp4 --output-dir output
```
Using the cenc protection scheme works perfectly on Chrome, however changing to cbcs results in a decode error. Interestingly Chrome reports this in the debug logs:
```
Selected FFmpegAudioDecoder for audio decoding, config: codec: aac, profile: unknown, bytes_per_channel: 4, channel_layout: STEREO, channels: 2, samples_per_second: 44100, sample_format: Float 32-bit planar, bytes_per_frame: 8, seek_preroll: 0us, codec_delay: 0, has extra data: true, encryption scheme: Unencrypted, discard decoder delay: true
FFmpegDemuxer: av_read_frame(): Invalid data found when processing input
```
There doesn't seem to be any clear lead in the resulting file, at least if I try play it with ffplay directly it complains about `Incorrect number of samples in encryption info`.
Running `mp4info` I can see that it does describe the encryption correctly:

Is is possible to check if used key for decryption is correct key?
Because now if key is correct mp4decrypt generates output and have exit code 0
mp4info not show that output file in this case if encrypted, but in fact output file is garbage...

```
export AA=687a6ad8f817d7cca5510acc76720636
echo ${AA} | xxd -p -r > test.key
```
Now I am delivering the manifest created as `content-type:application/vnd.apple.mpegurl` and test.key as `content-type:application/pgpkeys` and I also tried with `content-type:application/octet-stream`.
When I run this is safari my payback starts and timer starts moving but I cannot see anything in the video.

] | **Used version**
v1.6.0-637 (latest at the moment)
**Scenario**
Use mp4-dash.py util to generate Smooth Streaming compatible output by specifying `--smooth`.
**Problem description**
The track name in the audio URL template of the generated .ismc file mismatches the track name in the generated .ism file.
Example audio URL template and the audio portion in the corresponding .ism file:
```
// URL template in .ismc
QualityLevels({bitrate})/Fragments(English={start time})
```
```
// Audio portion in the corresponding .ism
<audio src="tears_audio_eng.mp4" systemBitrate="136075">
<param name="trackID" value="1" valueType="data"/>
<param name="trackName" value="audio_en" valueType="data"/>
<param name="timeScale" value="44100" valueType="data"/>
</audio>
```
The track name in the .ismc file `English` is supposed to match the one in the .ism file `audio_en`.
**Cause**
It seems it's introduced here:
https://github.com/axiomatic-systems/Bento4/commit/4916daf0#diff-e47888547647a4f042e89b39ca9f3db16ff8ec57ae8bf7eed250d050c6139061L1007

i know the mannual method to decrypt file using multiple keys like --key xxxxxx:xxxx --key xxx:xxxx so on...
and its working mannualy decrypt no issues...
but i dont want this as mannual...
i need that below script can check each key one by one and which is correct it decrypt mp4 file..
os.system('mp4decrypt' + ' --key ' + str(decrypt_key) + ' "' + download_path + 'vid_enc.mp4' + '" "' + download_path + 'vid_dec.mp4' + '"')
above script overwrites all keys and grab the last one.. it cant check all keys one by one..
so want mp4decrypt can check each key one by one...

] | mp42ts only outputs a PAT and PMT once at the beginning of the stream.
While the ISO/IEC 13818-1 which defines MPEG-2 TS does not define a repetition rate for PSI information (PAT, PMT) there are industry guidelines on repetition rates for this information:
TR 101 290 standard defines an error should be generated if PSI is not repeated every 500ms
ANSI_SCTE-137-6-2017 says '_It is recommended that the PAT repetition rate be eight per second and the
PMT repetition rate be eight per second_.'
ATSC recommended practice is: _PAT/PMT repetition interval error (200ms < cycle time ≤ 500ms)_
Many decoders choke on streams where PSI information is not repeated often enough.
I propose that PMT/PATs are inserted at least every 500ms in the output stream to comply with industry standards

] | Hello,
I have two files - isma (audio) and ismv (video) downloaded with YouTube. Both are DRM protected.
I also have right decryption key.
I have red "Dealing with ISMV and ISMA input files" so I used mp4fragment to fix lack of TFDTs. After fixing audio and video are playing with vlc, but they are obviously encrypted.
Unfortunately decrypting it with mp4decrypt changes nothing. I'm 100% sure that decryption key is correct. I have some experience with decrypting dash files, so I know how to properly use mp4decrypt. There is probably something in procedure, that I'm missing or there is some issue with Bento4 and ism files.
I've also tried to convert ism to dash (mp4dash.bat) and then merging parts binary with python, but there is no change. I still cannot properly decrypt neither audio or video. This method (binary merging and decrypting "native" mpd) works file with other (not ism) files so there is little chance that something is wrong on my side.
Any help would be much appreciated.

"axiomatic-systems",
"Bento4"
] | Good day,
I try to encrypt and decrypt a segment file (MP4 fragment) which has been generated by FFmpeg. Bento4 seems to provide multiple ways to do this, but all of them either fail with relatively unspecific error messages or end up just copying the file.
Input file(s)
===
I use a 25-fps file with one audio track and one video track (I tried multiple different ones). I encode the file using FFmpeg like this:
ffmpeg -i input.mp4 -acodec aac -vcodec h264_nvenc -b:v 2500k -g 5 -rc cbr_ld_hq -hls_segment_type fmp4 -hls_time 2 -hls_segment_filename stream-%%18d.m4s -hls_fmp4_init_filename init.mp4 -hls_playlist_type vod -t 10 index.m3u8
This generates a playlist (index.m3u8), an initialization segment (init.mp4) and five segments (stream-000000000000000000.m4s to stream-000000000000000004.m4s). For testing, I only use the initialization segment (init.mp4) and the first segment (stream-000000000000000000.m4s). They are placed in a folder called orig. I uploaded them as [segment.zip](https://github.com/axiomatic-systems/Bento4/files/5943732/segment.zip) here for reproducibility.
Encryption attempts
===
I tried to encrypt the first segment using the three different ways offered by Bento4 - mp4-hls, mp4-dash as well as mp4encrypt directly.
mp4-hls
---
.\Bento4-SDK-1-6-0-637.x86_64-microsoft-win32\utils\mp4-hls.py --exec-dir=.\Bento4-SDK-1-6-0-637.x86_64-microsoft-win32\bin --encryption-key=aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa:bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb -o enc\ orig\stream-000000000000000000.m4s
This call fails with the following output:
```
Parsing media file orig\stream-000000000000000000.m4s
ERROR: 'tracks'
```
It seems that mp4-hls does not support fragmented MP4 files (that's reasonable since there is no parameter to pass the initialization segment). A more specific error message would, however, be nice.
mp4-dash
---
.\Bento4-SDK-1-6-0-637.x86_64-microsoft-win32\utils\mp4-dash.py --exec-dir=.\Bento4-SDK-1-6-0-637.x86_64-microsoft-win32\bin --encryption-key=aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa:bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb --encryption-cenc-scheme=cbcs --init-segment=orig\init.mp4 --hls -o enc\ orig\stream-000000000000000000.m4s
This call fails and prints "ERROR: 'tracks'". As this was not very descriptive, I investigated it in a debugger and found that mp4info seems to be unable to find any tracks. I do not understand why. However, a more detailed error message would, again, be nice.
mp4encrypt
---
I tried encryption with two different methods:
.\Bento4-SDK-1-6-0-637.x86_64-microsoft-win32\bin\mp4encrypt.exe --method MPEG-CENC --key 1:aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa:bbbbbbbbbbbbbbbb --key 2:aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa:bbbbbbbbbbbbbbbb --fragments-info orig\init.mp4 orig\stream-000000000000000000.m4s enc\stream-000000000000000000.m4s
.\Bento4-SDK-1-6-0-637.x86_64-microsoft-win32\bin\mp4encrypt.exe --method MPEG-CBCS --key 1:aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa:bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb --key 2:aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa:bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb --fragments-info orig\init.mp4 orig\stream-000000000000000000.m4s enc\stream-000000000000000000.m4s
Both calls seem to generate an encrypted fragment named stream-000000000000000000.m4s in the folder enc, but I cannot get them decrypted (see below).
Decryption attempts
===
I tried to decrypt the encrypted segment (that I generated with mp4encrypt) in two different ways - with mp4decrypt and with a specifically designed playlist to be used with FFplay.
mp4decrypt
---
.\Bento4-SDK-1-6-0-637.x86_64-microsoft-win32\bin\mp4decrypt.exe --key 1:aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa --key 2:aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa --fragments-info orig\init.mp4 enc\stream-000000000000000000.m4s dec\stream-000000000000000000.m4s
This call seems to succeed, but the output segment is bit-identical to the input file. mp4decrypt seems to just copy the file and there is no error message.
FFplay
---
To play back the encrypted segment (forcing decryption in the process), I copy the initialization segment (init.mp4) and the encrypted segment into a new folder, add a key.bin file with 16 bytes of "aa" (hex) and design a playlist (index.m3u8) file like the following:
```
#EXTM3U
#EXT-X-VERSION:7
#EXT-X-TARGETDURATION:2
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-MAP:URI="init.mp4"
#EXT-X-KEY:METHOD=AES-128,URI="key.bin",IV=0xBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
#EXTINF:2.000000,
stream-000000000000000000.m4s
#EXT-X-ENDLIST
```
*Note: I adjust the IV depending on the method, see above*.
Attempting to play back the playlist with
ffplay -allowed_extensions ALL .\index.m3u8
results in FFplay not recognizing the file properly:
Could not find codec parameters for stream 0 (Video: h264 (avc1 / 0x31637661), none, 1920x1080): unspecified pixel format
Question
===
How can I use Bento4 to encrypt and decrypt an FFmpeg-generated fMP4 segment? Decryption can be done by either Bento4 or FFplay. I explained my attempts above - if I have made a mistake somewhere, please let me know and maybe use it as input for some more detailed error messages, where applicable.

] | Hi!
When creating hls playlist from video, duration of last segment in variant playlist calculated incorrectly. When last segment is one sample only, this cause to create playlists with zero duration chunks `#EXTINF:0.000000,` which cause `-16240` error on ios 14.2+ devices while trying download content.
Here command to reproduce issue:
```(sh)
wget https://storage.yandexcloud.net/github-public/video_sdr_avc_1280x534_2400_4000_720p.mp4
mp42hls --hls-version 7 --segment-duration 4 --verbose --segment-filename-template %d.ts --segment-url-template %d.ts --index-filename video_sdr_avc_720p.m3u8 --iframe-index-filename video_sdr_avc_720-iframes.m3u8 video_sdr_avc_1280x534_2400_4000_720p.mp4
```
Result playlist contains zero duration segment:
```(sh)

] | Hi @barbibulle ,
I have some feedback on using mp4dash to create HLS multi-DRM with cbcs encryption:
When using a command such as the following:
`mp4dash --encryption-key=43215678123412341234123412341234:12341234123412341234123412341234 --encryption-cenc-scheme=cbcs --hls --fairplay-key-uri=skd://43215678123412341234123412341234 --widevine --widevine-header=provider:intertrust#content_id:2a ToS-360_keyint_24_frag_4s_wk.mp4 ToS-540_keyint_24_frag_4s_wk.mp4 ToS-720_keyint_24_frag_4s_wk.mp4`
Although it creates Widevine and FairPlay signaling, it can only playback properly with Widevine, and not FairPlay
1. FairPlay documentation state that
FPS does not support the IVs listed in EXT-X-KEY tags,
FPS does not support using IVs as media sequence numbers
All segments must be encrypted with the same IV
The license server must deliver the IV in the CKC response, hence has to know the IV upfront
The option I found to set the IV is to use --encryption-key option such as the following undocumented way:
`--encryption-key=<KID>:<KEY>:<IV>`
Could you add that in mp4dash documentation maybe ?
Also, since that is the only supported option with FPS, it would be good to restrict to only this encryption-key setting when hls and FairPlay are set. What do you think ?
2. As for Widevine signaling, an example of such signaling is
`AAAASXBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAACkIARIQQyFWeBI0EjQSNBI0EjQSNBoKaW50ZXJ0cnVzdCIBKkjzxombBg==` which decodes into

"algorithm":"AESCTR",
"keyIds":["QyFWeBI0EjQSNBI0EjQSNA=="],
"provider":"intertrust",
"contentId":"Kg==",
"protectionScheme":1667392371
}
per Widevine UAT Diagnostic console https://integration.uat.widevine.com/diagnostics
In order to be consistent, I think it will be better to have the Widevine PSSH to signal CBCS instead of CTR encryption | CMAF HLS cbcs | https://api.github.com/repos/axiomatic-systems/Bento4/issues/555/comments | 2 | 2020-09-30T16:44:32Z | 2020-10-03T15:14:45Z | https://github.com/axiomatic-systems/Bento4/issues/555 | 712,107,252 | 555 |

so i am trying to cut segments to have a certain start_time and duration by constructing a video of a certain length then forcing ffmpeg to add an Iframe every **duration * fps** frames ` ffmpeg -i video.ts -force_key_frames "expr:gte(t,n_forced*GOP)" video.mp4` ,
The problem is that mp42ts doesn't always respect the ` --segment` option and just adds between 0.5-1.5 seconds,
So i suspected Iframes and i used ffmpeg to make every frame of the video an Iframe which resulted in a huge video but i can live with it and i checked that iframes truly exist `ffprobe -select_streams v -show_frames -show_entries frame=pict_type -of csv video.mp4 | grep -n I | cut -d ':' -f 1`,
The problem with that particular case is that mp42ts decides to ignore the decimal part and just treats as an integer so if i put an option `--segment 8.4` , it cuts to 8.0
I tried it with many videos.
The reason why i insist on using Bento4 actually is its extreme speed,

I wonder if anyone tried playing back DASH + PR CBCS in Edge/IE? I tried a test content from MS Test Server (https://testweb.playready.microsoft.com/Content/Content4X - APPLESET-DASH-CBCS-bbb) in the dash.js (3.0.3) and it plays fine after getting a license in Edge Chromium and IE11. I have tried packaging my own content with the same keys and the playback fails.

The command that I have used is above. First four groups of data in the Content Key were reversed to be correctly represented in hex format. But, neither "7d5b7d5b7d5b7d5b7d5b5b7d5b7d5b7d", nor "5b7d5b7d5b7d5b7d5b7d5b7d5b7d5b7d" make the playback work, so it may be something different.

Not sure if it's me using a wrong command or something else. Any advice is highly appreciated.

] | > mp4hls is a tool that creates a multi-bitrate HLS master playlist from one or more MP4 files, including support for encryption and I-frame-only playlists. **This tool uses the mp42hls low level tool internally, _so all the options supported by that low level tool are also available_.**
This is not holding true here. A flag supported by `mp42hls` is not being respected by `mp4hls`.
Command:
```bash
$ mp4hls \
--hls-version 3 \
--encryption-key `openssl rand -hex 16` \
--encryption-iv-mode random \
--output-single-file \
--output-encryption-key \
--segment-duration 10 \
--segment-filename-template randomstrhere \
input.mp4
``` | mp4-hls.py: error: no such option: --segment-filename-template | https://api.github.com/repos/axiomatic-systems/Bento4/issues/541/comments | 3 | 2020-08-10T09:33:13Z | 2020-08-17T03:56:52Z | https://github.com/axiomatic-systems/Bento4/issues/541 | 675,999,528 | 541 |
