I will point out that my file outaaceditlist.mp4 is invalid in one little case, because of this bug in ffmpeg: https://github.com/FFmpeg/FFmpeg/commit/f37e66b3937a914e16d89a9050f042ad89567245 mdhd atom MUST CONTAIN duration pre media time's editlist...

New sample https://user-images.githubusercontent.com/31514790/151662537-de43900f-ecdf-4238-9ede-d5d2de671a80.mp4 and EAC3 (EAC3 is still wrong duration though in edit list and no sgpd/sbgp, though standard says roll is needed) https://user-images.githubusercontent.com/31514790/151820288-94c8a78b-1f8a-48e7-b4ca-32de01b59c87.mp4

Updated eac3 sample that I duplicated by mistake with aac sample. So again, no roll metadata in eac3 that is supposed to be there per standard, and no correct media...

This is now fixed. Channel layout : C L R Lw Rw Ls Rs LFE > FFmpeg might be helpful in these cases Be very accurate about aac in ffmpeg....

> will Google let you stream a video file with TrueHD in your browser? Yes. But it reencodes it... e.g. https://drive.google.com/file/d/1e0gfDIsNQKfJSrKV7eaL3izQWZg1XUQ-/view?usp=drivesdk You can say since ffmpeg can see AC3 stream...

That is confusing, for example, if for aac and eac3 delay of 1024 samples and 256 samples is specified (it is always there), but that does not means there is...
