All other commands also work normally except the audio. Without having looked at the files. My conclusion is that the problem appears after cutting with H264Player_install.exe, is that correct ? If correct, cut under linux. If you know where to cut, it’s quit easy. ffmpeg -ss 10 -i source.ext -t 30 source-cutted.ext Result: 30 seconds from source.ext where the first 10 seconds are skipped. > > - https://www.dropbox.com/s/qgyulo8mbnqkwub/Video1.264?oref=e&n=451062852 > (file full) > > On 30-07-2015 17:33, Henk D.
