FFmpeg four audiochannels but the first two are static noise
2 octobre 2014, par sebastianI have a handful of videos with one audio stream in which includes four audio channels. I am having trouble in getting the last two channels wherein lies the actual sound. I don’t want to create wave files or anything like that I just want to create a video out of it with the two channels correct channels (three and four). I was thinking about using the
-map 0:a:2
and-map 0:a:3
but it does not work quite as well as I had hoped for. Does anyone know a better way or what I am doing wrong ?
Any help would be appreciated.Audio

ffmpeg combining audio tracks on copy
22 janvier 2024, par janedenI tried to copy all streams (video, audio, subtitle) and add a tag with the following command in order to play the files using QuickTime player :


ffmpeg -i in.mp4 -vcodec copy -tag:v hvc1 -acodec copy -scodec copy -map 0 out.mp4



The resulting file does open with QuickTime player, and the video/subtitles play fine, but the two audio tracks (E-AC3 in English and German) from the input file cannot be selected (
View → Languages → None
) and are in fact merged into each other while playing the video, even though both tracks are shown separately inInspector → Audio Details
and VLC handles them correctly. Is this a bug in QuickTime player, or would I need to add another option for QuickTime ?
