Note - More test streams are in the ref'd issue (which may or may not be exactly the same issue - it's worth checking those ones too).

Could be that the ref'd issue is different after all. This stream (#5107) apparently doesn't detect a video track at all, whereas the other one (#5108) detects a track but only shows a black screen.

Do I have any update on this issue. We are eagerly waiting for your feedback.

It would seem to me that the video in [1] uses a stream type that we don't support. I'll mark as an enhancement and will have a look as soon as I have some time. @chakravarthidantu you are also welcome to send a pull request for adding support.

Even though the stream type is not supported, at least video track should appear right. If video track is rendered and exo player dont have support for that format, I can understand, but how to solve video track issue.

Do you have any solution to get video track to be rendered by exo player (even if playback fails).

[AquilesCanta]

We don't support as in ExoPlayer's TS extractor doesn't support. The video track is not detected by ExoPlayer, and implementing extraction of this type of track (for future reference [1]) might not be a trivial task. MP4-part 2 has some similarities with h263 (see #1603) on sample level, from what I've seen. But I don't know if extraction has any overlapping work to be done. I cannot look into this for the time being, unfortunately.
