] | #### Description:
I want to merge 2 (or more) dash manifests into 1, each in a different period.
I understand this can be done using a playlist `gpac -i playlist.m3u -o manifest.mpd:sigfrag` and `sigfrag` for manifest generation only.
```
##begin pl.m3u
#props=#Period=1
asset1/manifest.mpd
#props=#Period=2
asset2/manifest.mpd
##end playlist
```
#### Expected:
All AdaptationSets & all Representations are in the new manifest.
#### Actual:
Only 1 video and 1 audio AdaptationSet/Representation is taken from the original manifests.
#### Environment:
- macOS Monterey 12.0.1 (Apple M1)
- GPAC version 1.1.0-DEV-rev1491-g5bed60917-master and 1.0.1 (released in September 2020) from the Downloads page | How to merge 2 (or more) existing DASH manifests | https://api.github.com/repos/gpac/gpac/issues/1954/comments | 1 | 2021-12-08T07:01:55Z | 2021-12-08T20:47:38Z | https://github.com/gpac/gpac/issues/1954 | 1,074,078,493 | 1,954 |

Detailed guidelines: http://gpac.io/2013/07/16/how-to-file-a-bug-properly/
Sorry for the question, but I just wanted to confirm something.
I'm trying to move an H.265 video from an MKV container to an MP4 container. When doing this with FFmpeg, it mangles the framerate (changing what was constant to a variable framerate). For integer framerates, I am able to use `-video_track_timescale 60` to work around this issue with FFmpeg, but it doesn't work with framerates like 59.94.
I am able to successfully do what I need with MP4Box after extracting the video with mkvextract, but, as I often work with files in the hundreds of gigabytes, I wonder if this is possible with one step. `:fps=x` works fine with the extracted H.265 file, but not with the original MKV. Just wanted to make sure I wasn't overlooking anything and that extracting the file first with mkvextract is my only option here.

] | **Info:**
MP4Box - GPAC version 0.5.2
Ubuntu 20.04
**Problem:**
I have .h264 video files which i need to convert to .mp4.
This works perfectly fine on test files that have no special characters in their names.
Working command: `MP4Box -add ./static/video/myfile.h264 ./static/video/test.mp4`
Now my production files have a different file name which contains the date and time of creation
separated by "-" "@" ":" and "/" characters. MP4Box can't work with them i guess because of the file name.
The files are fully intact and not corrupted or anything. If i change file name to something without the
special characters it works fine.
The following command does not work:
`MP4Box -add ./static/video/2021-05-10_11:20:03.h264 ./static/video/2021-05-10_11:20:03.mp4`
```

Error importing ./static/video/2021-05-10_11:20:03.h264: Requested URL is not valid or cannot be found
```
I can tell that in the first line of the error message the file name gets cut off. I don't know if this could give a hint to the solution of the problem.
Using the same file names works perfectly with tools like FFmpeg etc. I can't really tell if my file names are too long for MP4Box or if MP4Box doesn't like special chars in file names.

`-splitz (string): extract the specified time range so that ranges A:B and B:C share exactly the same boundary B:`
it only takes `start_second:end_seconds`, why does document mention 3 points?

] | While running `MP4Box -diso ...` xml dump on files in the ISOBMFF conformance suite, I noticed that MP4Box has issues with some of the files:
1. Two files produce invalid xml files ([09_text.mp4](https://conformance.mpeg.expert/ISOBMFF/published/isobmff/09_text.mp4), [22_tx3g.mp4](https://conformance.mpeg.expert/ISOBMFF/published/isobmff/22_tx3g.mp4))
The issue seems to come from the dump of the `DefaultBox` where the closing xml tag is missing.
It looks like `gf_isom_box_dump_done` call is missing in https://github.com/gpac/gpac/blob/54bce6b07332fabb016cf9a4ae9b80aa33bca3cd/src/isomedia/box_dump.c#L1929
2. Three files can not be opened at all.

"gpac",
"gpac"
] | Hi, I'm using GPAC in order to do DRM encryption with m4s chunks (from preiously generated dash), like in #924 and #1607
So I use commands:
MP4Box -stats -crypt gpac_drm_widevine.xml init_a.m4s -out init_a_drm.m4s
MP4Box -stats -crypt gpac_drm_widevine.xml init_v.m4s -out init_v_drm.m4s
MP4Box -stats -crypt gpac_drm_widevine.xml -init-seg init_a.m4s seg1_a.m4s -out seg1_a_drm.m4s
MP4Box -stats -crypt gpac_drm_widevine.xml -init-seg init_a.m4s seg2_a.m4s -out seg2_a_drm.m4s
MP4Box -stats -crypt gpac_drm_widevine.xml -init-seg init_v.m4s seg1_v.m4s -out seg1_v_drm.m4s
MP4Box -stats -crypt gpac_drm_widevine.xml -init-seg init_v.m4s seg2_v.m4s -out seg2_v_drm.m4s
...
The problem is that I'm not sure how to use the values given by my content provider in the conf.xml file. It gives me this info:
"key_id_hex":"652B...4DB", (32 chars)
"content_key_hex":"E49F...907", (32 chars)
"iv_hex":"34323...3562", (32 chars)
"playready_pssh_data":"iAMA......", (very long pssh data)
"playready_system_id":"9a04f079-9840-4286-ab92-e65be0885f95",
"widevine_drm_specific_data":"Igtnb2...bBg==", (base64, but if i convert to HEX, 34 chars)
"widevine_drm_specific_data_with_key_id":"EhB...tTbIgtnb2...bBg==", (contains the widevine_drm_specific_data). Base64, 70 chars in hex (36 + 34)
"widevine_system_id":"edef8ba9-79d6-4ace-a3c8-27dcd51d21ed",
Here I have two keyIDs, the main one, and a widevine specific data one. How should i use this information. I've tried all combinations, here is one of them:
```xml
<?xml version="1.0" encoding="UTF-8" ?>
<GPACDRM type="CENC AES-CTR">
<!-- Widevine -->
<DRMInfo type="pssh" version="0">
<BS ID128="EDEF8BA979D64ACEA3C827DCD51D21ED"/>
<BS data="0x08011210"/>
<BS ID128="0x652B...4DB"/>
<BS data64="Igtnb2...bBg=="/>
</DRMInfo>
<CrypTrack trackID="1" IsEncrypted="1" first_IV="0x34323...3562" saiSavedBox="senc">
<key KID="0x652B...4DB" value="0xE49F...907"/>
</CrypTrack>
</GPACDRM>
```
The process works ok, but then I can't see the content in my provider player.
So I supose there is a problem with the encryption, because if I use other encription process (from unified streaming), the video plays fine.
Please, can you help me to know how should I use my encryption provided info in the conf.xml?
Thank you very much

] | Hi, so it looks like the compositor still has issues whilst trying to playback live tiled dash streams as it stops and displays:
`[Compositor] Could not detect end of stream(s) in the last second, aborting`
However, when just playing in normal mode (dashin->vout), the stream plays back smoothly.
Here are the commands used:
For the encoder:
```
#!/bin/bash
export ISIZE=6000x3000
export TILES=6x6
export OSIZE=1024x512
gpac -i test_30fps.mp4:FID=I reframer:rt=on:SID=I:FID=REGULATED\

ffenc:SID=Y:FID=K1:c=libkvazaar:b=10M:size=$OSIZE:fintra=4:rc\
tilesplit:SID=K1:FID=1\
-o http://localhost:8080/live.mpd:gpac:dmode=dynamic:segdur=4:cdur=2:asto=2:llhls=off:profile=live:rdirs=outdir:template=seg_live_:SID=1 -stats -logs=all@info -lu -log-file=file_to_tiles.log
```
For the compositor playback:
```
#!/bin/bash
gpac -blacklist=nvdec --lowlat=no compositor:src=http://192.168.123.203:8080/live.mpd#VR vout:buffer=8000 -graph -logs=dash@info -lu -log-file=play_compositor_not_ok.log
```
For the regular playback (dashin->vout)
```
#!/bin/bash
gpac -i http://192.168.123.203:8080/live.mpd dashin:lowlat=no tileagg ohevcdec vout:buffer=8000 -graph -logs=dash@info -lu -log-file=play_equirect_ok.log
```
As you can see, the content is streamed and played back from 2 different machines, on the same gigabit local network. (this could have an effect)
Both machines run:
GPAC version 1.1.0-DEV-rev1382-g08e1f404e-master
Ubuntu 21.04

So, when encoding a FFAVIN stream into a tiled dash, I have this warning message:
`[FFAVIn] Unknown frame rate, will use 25 fps - use `:#FPS=VAL` to force frame rate signaling`
However, when looking at the filters documentation either [here](https://github.com/gpac/gpac/wiki/ffavin) or `gpac -hx ffavin `, nothing seem to be corresponding to this warning message.
1. What is the relevant option?
2. Is there a way to make the warning message more explicit?

```
MP4Box -add dav1_10.obu -new test.mp4
[AV1] parsing for metadata is not implemented. Forwarding.
[Importer] Error probing dav1_10.obu
Error importing dav1_10.obu: Bad Buffer size (too small)
```
Now I think this might be an experimental file, but I'm not sure at all.
The OBU file parses correctly using https://github.com/yohhoy/av1parser
But `aomdec` does say the frames are corrupted.
The file also does not seem to follow AV1's ITU-T T.35 specification for the Dolby Vision metadata, so it might just be bogus.
I am using GPAC on Arch Linux, 64 bits.

I was wondering if mp4box could be used to turn the depth map stream (Track No. 2) into the main video track. For example, how would one go about changing `Type "auxv:dish"` into `Type "vide:hvc1"` to see if any player would be able to render the depth map?

```
int main(int argc, char *argv[])
{
gf_sys_init(GF_MemTrackerSimple, NULL);
gf_log_set_tool_level(GF_LOG_ALL, GF_LOG_INFO);
FILE* logfile = gf_fopen("/home/rodolphe/api_compositor_no_mainthread.log", "wt");
gf_log_set_callback(logfile, on_atscd_log);

// loadSource("/home/rodolphe/test_30fps.mp4", fsess); works OK
loadFilter("compositor:src=/home/rodolphe/test_30fps.mp4", fsess); // cracking sound
loadFilter("vout", fsess);
loadFilter("aout", fsess);
while(!gf_fs_is_last_task(fsess)) {
usleep(1000);
gf_fs_run_step(fsess);
}
gf_fclose(logfile);
}
```
When executing this file but using the loadSource version, it works perfectly, the video is smooth, the audio plays perfectly.
When the loadSource is replaced by a compositor filter with the file as source, the audio cracks.

Side questions:
- How can we influence upstream parameters from the compositor? (lowlat/tiledrop)
- The playback using live DASH sources seems very choppy too, maybe this is also related to this issue.

```
produces a sync file.
Uploaded the files to my [url=https://drive.google.com/drive/folders/1X4xxJ5h8I6Ed00yc8sTIfJmDG-DnSpXL]GoogleDrive[/url].
I also reencode the audio file with different aac encoders, but that didn't change a thing. Muxing with mkvmerge works fine, muxing with MP4Box is async.

Hi,
I am having trouble packaging a VVC bitstream using the current master branch. The CTS timestamp for the encoded frames jumps, when a CRA or IDR frame with leading pictures is encountered. The problem lies somewhere in the parsing of the bitstream.
For example, given a bitstream with GOP size 16 and an intra period of 32 I get the following output, when inspecting the raw bitstream (`bin/gcc/gpac -i BasketballPass_QP37.266:fps=50 inspect:deep`):
```

The interesting part is around PCK 18. This is the CRA picture with POC 32, but it gets assigned CTS 17, although there are some leading pictures, which should come before it. Due to that error all following pictures in decoding order also get wrong a CTS (e.g. next PCK is a RASL with POC 24, but gets cts 41).
This is what the corresponding log file from the encoder looks like:

I used VVenC here, but the problem is basically the same when using VTM (13.2).

Different from issue 1911, the overflow memory is related to szXmlFrom parameter. The szXmlTo para has the same problem, please fix them together.
Buggy code at dmx_nhml.c:1008:
```

Detailed guidelines: http://gpac.io/2013/07/16/how-to-file-a-bug-properly/
This is with gpac master 8d9ccb02e (`GPAC1.1.0-DEV-rev1210-g8d9ccb02e-master`). The issue is not dependent on the host operating system, but for your information, I am using Ubuntu Linux 20.04 LTS here.
As input we have a AV1 elementary stream, provided as a [input.ivf](https://live.unified-streaming.com/dimitry/gpac-av1-mux/input.ivf) file (~347 MiB). We then create a progressive MP4 file using MP4Box, e.g.:
```
MP4Box -add input.ivf output.mp4
```
The resulting MP4 file has more sample descriptions than necessary, because it repeats the first sample description, but leaves out the Sequence Header OBU. E.g., the first sample description contains the Sequence Header OBU, followed by two metadata OBUs (HDR_MDCV and HDR_CLL), while the second sample description contains *only* the same two identical metadata OBUs:
```xml

In the `SampleToChunkBox` you can see that it flips between these two sample descriptions:

...

<SampleToChunkEntry FirstChunk="600" SamplesPerChunk="2" SampleDescriptionIndex="2"/>
<!-- counted 6314 samples in STSC entries (could be less than sample count) -->
</SampleToChunkBox>
```
But it seems that having more than one sample description is not needed at all. You could have just the first sample description, and point all the samples to that first one, since the Metadata OBUs are exactly the same, and any valid sample description should really contain a Sequence Header OBU. At least, this is how I would interpret the [AV1 Codec ISO Media File Format Binding](https://cdn.rawgit.com/AOMediaCodec/av1-isobmff/v1.1.0/).
I did some debugging of the logic in `src/filters/mux_isom.c` and `src/filters/reframe_av1.c`, and it turns out that the `mp4_mux_setup_pid()` function (in `src/filters/mux_isom.c`) concludes every few samples that the decoder config changed. I.e. `needs_sample_entry` gets set to nonzero, because the CRC of the `GF_PROP_PID_DECODER_CONFIG` property changed. However, this change is only because `av1dmx_check_pid()` (in `src/filters/reframe_av1.c`) always throws away *all* OBUs and starts from scratch:
```c
} else if (ctx->is_av1) {
//first or config changed, compute dsi
while (gf_list_count(ctx->state.config->obu_array)) {
GF_AV1_OBUArrayEntry *a = (GF_AV1_OBUArrayEntry*) gf_list_pop_back(ctx->state.config->obu_array);
if (a->obu) gf_free(a->obu);
gf_free(a);
}
dsi = NULL;
dsi_size = 0;
while (gf_list_count(ctx->state.frame_state.header_obus)) {
GF_AV1_OBUArrayEntry *a = (GF_AV1_OBUArrayEntry*) gf_list_get(ctx->state.frame_state.header_obus, 0);
gf_list_add(ctx->state.config->obu_array, a);
gf_list_rem(ctx->state.frame_state.header_obus, 0);
}
gf_odf_av1_cfg_write(ctx->state.config, &dsi, &dsi_size);
if ((!ctx->fps.num || !ctx->fps.den) && ctx->state.tb_num && ctx->state.tb_den && ! ( (ctx->state.tb_num<=1) && (ctx->state.tb_den<=1) ) ) {
ctx->cur_fps.num = ctx->state.tb_num;
ctx->cur_fps.den = ctx->state.tb_den;
}
}
```
I think it should always keep at the last encountered Sequence Header OBU, and not throw it away. For example, in the first loop where it pops all the list items from `ctx->state.config->obu_array`, save the Sequence Header OBU separately, and if `ctx->state.frame_state.header_obus` does *not* start with a Sequence Header OBU, insert it again. But this could be done in several different ways.
In any case, if the resulting `ctx->state.config->obu_array` will then start with the same Sequence Header OBU, the decoder configuration (`dsi`) will come out as bit-identical, so its CRC won't change and the same sample description can be re-used for all samples in the stream.

Hi, there.
There is a segmentation fault caused by null pointer dereference in mpgviddmx_process, reframe_mpgvid.c:643 in commit d003a572d57. It seems to be an incomplete fix of issue #1887 and causes another problem.

Hi, there.
There is a segmentation fault caused by buffer overflow (overwrite) in svc_parse_slice, av_parsers.c:5788 in commit 592ba2689a3.
This vulnerability is similar to the npd reported in #1898. However, this one is more serious since it allows memory manipulation.

The reason for this bug is that the program does not check the nullity of the pointer before copy memory to it.

Buggy code and reason:
in isom_hinter.c:950
```
for (i=0; i<gf_isom_get_sample_description_count(tkHint->file, tkHint->TrackNum); i++) {
u8 *tx3g; <---with out init
...
gf_isom_text_get_encoded_tx3g(..., &tx3g, &tx3g_len); <--- supposed to init tx3g
...
gf_free(tx3g); <--- free tx3g
...
}
```
It is supposed to init tx3g in gf_isom_text_get_encoded_tx3g, but in gf_isom_text_get_encoded_tx3g, it might forget that mission.
```
GF_Err gf_isom_text_get_encoded_tx3g(GF_ISOFile *file, u32 track, u32 sidx, u32 sidx_offset, u8 **tx3g, u32 *tx3g_size)
{
...
// it returns without init tx3g once a->type equals another value;
if ((a->type != GF_ISOM_BOX_TYPE_TX3G) && (a->type != GF_ISOM_BOX_TYPE_TEXT)) return GF_BAD_PARAM;
...
*tx3g = NULL; <--- real init here
*tx3g_size = 0;
gf_bs_get_content(bs, tx3g, tx3g_size);
gf_bs_del(bs);
return GF_OK;

Detailed guidelines: http://gpac.io/2013/07/16/how-to-file-a-bug-properly/
Hi GPAC Devs,
I followed the official wiki guidance and setup a hevc tiling live streaming on a linux server, building latest gpac main branch code and ffmpeg with libkvazaar.
Everything works fine when the input stream res is 1920x960. But when I change the stream res to 3840x1920, I can not get the output dash stream to play. The gpac player (windows based) continues to pop error infos like this:
**[DASH] Error in downloading new segment http://192.168.1.213:8070/stream/liveTest4K/live_dash_track1_20.m4s: Requested URL is not valid or cannot be found**.
Would you guys kindly help me out of this?
Thank you very much.

It's a heap-buffer-overflow bug caused by missing '\0' check of the end of URI.
**Step to reproduce:**
1.get latest commit code (MP4Box - GPAC version 1.1.0-DEV-rev1169-gbbd741e-master)
2.compile with --enable-sanitizer
3.run ./MP4BOX -hint poc -out /dev/null

Archive of the files used for this issue: https://www.mediafire.com/file/laq9u10c8jdgecx/tiled_playback_error.zip/file
It contains:
- cnpp.mp4, the video file used as input
- the logs of the player and the encoder sessions
### How to reproduce
Server Side:
```

-graph -lu -stats -logs=all@info -log-file=file_to_tiles_server.log
```
Client Side:
`gpac -i http://localhost:8080/live.mpd dashin:tile_mode=center tileagg ohevcdec vout -graph -logs=all@info -lu --skip_lqt -log-file=file_to_tiles_player.log`
### Observed behaviour
The playback is choppy. Every N seconds, the playback stops, I see the segments being downloaded in the terminal, and starts again. This behaviour is only observed in tiled mode, when the tiling parameters are removed from the encoder (tilesplit acting then as a pass-through) and from the client, everything plays smoothly.
The encoder seems to run perfectly, however it displays warnings like this:
```
UTC 2021-08-08T19:15:12Z (TS 1628450112654) - [Dasher] AS-1 Rep 1 segment 3 done TOO LATE by 1000 ms

UTC 2021-08-08T19:15:12Z (TS 1628450112654) - [Dasher] AS-1 Rep 5 segment 3 done TOO LATE by 1000 ms
```
When the same configuration is ran with tiling disabled, the same warning appears (though only once since there is only one representation), though it seems to have no impact on the playback.
I have tried also by disabling the lowlatency mode on the player and encoder side, the playback is still choppy.
### Configuration
OS: Ubuntu 20.04
Version: f42841f7105433023fcbdace975713873474ac95 compiled in release

Hi,
I'm trying to use GPAC with python.
The process is a little tidious as the `libasan.so.5` has to be preloaded, even though I'm using the sanitizer option upon configurating it:
### Configuration // Compilation
I'm doing :
```sh
./configure --use-ffmpeg=local --enable-debug --prefix=/folder --bindir=/folder/bin --extra-cflags=-I/usr/local/cuda/include -I/folder/include --extra-ldflags=-L/usr/lib -L/usr/local/cuda/lib64 -L/folder/lib --enable-sanitizer
#compile
make -j$(nproc)
sudo make install
```
### Usage
1) Edit `/etc/ld.so.conf` and add `/folder/lib` , then `sudo ldconfig`
2.1) Find libasan :
```sh
echo 'void foo() {}' | gcc -x c -fPIC -shared -fsanitize=address -
ldd a.out | grep libasan.so | awk '{print $3}'
```
gives me : `/lib/x86_64-linux-gnu/libasan.so.5`
2.2) Preload it :
```sh
LD_PRELOAD="/lib/x86_64-linux-gnu/libasan.so.5" python3 test.py
```
test.py :
```python
import sys
sys.path.append("/folder/share/gpac/python")
import libgpac as gpac
gpac.init()
fs = gpac.FilterSession()
f1 = fs.load_src("/home/pierre/Documents/test.mp4")
f2 = fs.load("vout")
f3 = fs.load("aout")
fs.run()
```
I'm on ubuntu 20.04, running GPAC `1.1.0-DEV-rev1165-gccba035a1-master` .
This seems rather convoluted to get it to work no?
If I'm removing the flag `--enable-sanitizer` then gpac throws the error about the sanitizer:
```sh
==20499==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.
```
If I don't add 2), then the python command throws that same error, :/ .
Or am I missing something in my config?
Best,
