Is there any case for a mov and mp4 containers be interchangeable ?
13 avril 2018, par danielfrancaThe question migh be silly,
But I got the following situation.I have a bunch of MOV video files from some clients, I was going to convert them to MP4 to be able to run on a browser.
However, when I just tried to open it on the browser it worked fine, both in Firefox and Chrome.When I run ffmpeg on one of those files I get fhe following :
ffmpeg -i MyVideo.mov -hide_banner

ffmpeg adding 6 secs of black frames in the beginning of a file
7 août 2014, par user3842039Trying to convert a .mov file (h264 and pcm) generated in Mpegstreamclip (MacOS) and the result is strangely out of sync with around 6 seconds of black frames at the beginning. I have tried many differente audio and video codec and the result is the same even with a -vcodec copy and -acodec copy. Below the return of ffmpeg (git version compiled today - 06/08/2014) :
ffmpeg -i /media/dados/x/PGM-970.mov -vcodec copy -acodec copy /media/dados/convertidos/PGM-970-converted-ffmpeg-compilado.mov
