cutting mp4 with codec copy results no audio in browser
16 novembre 2020, par LukaI'm editing a video clip with ffmpeg. The original does not play in Firefox browser by itself. It does normally in Chromium. I do something like :


ffmpeg -ss 00:05:10 -i INPUT.mp4 -c copy OUTPUT.mp4



the resulting clip plays in Firefox but there's no audio. This happens in Firefox (82.0.3), but not in Chromium (86.0.4240.75). In chromium the sound is ok.


If audio is reencoded with


ffmpeg -ss 00:05:10 -i INPUT.mp4 -c:v copy -ab 360kb OUTPUT.mp4



resulting clip is playing ok in Firefox.


Could anyone explain what is happening here and is it possible to cut the mp4 without reencoding audio resulting in a clip that plays in Firefox too ?

EDIT :


I'm providing links to original files, but a bit of warning, they are 4-5GB big each :


- 

- original recording from blackmagic switcher/capture/recorder (this does not play in firefox at all, but does in Chromium)
- cut version made with
-codec copy
(plays in firefox but no audio. plays in chromium ok) - cut version with re-encoded audio (plays ok in both firefox and chromium)
