Contents: per camera view, every stride-th decoded frame (stride = ceil(fps) // 4: 15 at 60 fps, i.e. 4 fps), short side
resized to 256 px (aspect kept, antialiased bilinear), JPEG quality 90, in the TAS frame-cache "jpeg"
format: <view>/<recording>.s<stride>.ss256.jpg.bin (the JPEGs back to back) + .jpg.idx.npy (n + 1 byte offsets);
<view>/meta.json per recording: decoded frames, fps, stride, sampled frames, cached size. Built with
