note that the bug could be also in ffmpeg muxer, however VLC nightly is able to open the file

:rillian are vp9 in MP4 specs even finalised yet?

Comment 3

[Alfredo Yang (:alfredo)]

This file is non-fragmented mp4. I'm not sure stagefright's status but mp4 rust parser doesn't support non-fragmented file yet.

Comment 4

[Ralph Giles (:rillian)]

What Alfredo said. This file hits the is-fragmented check at in MP4MetadataRust::ReadTrackIndex https://dxr.mozilla.org/mozilla-central/source/media/libstagefright/binding/MP4Metadata.cpp?q=MP4Metadata.cpp#853 and decode fails there. Support for the non-fragmented case is still pending.

I attached a file which *should* be a non-fragmented file, and nightly plays it fine.

That could be a bug in stagefright :-P

However our focus is on getting the Rust demuxer working for MSE so non-fragmented is not a high priority.
