When capturing input with ffmpeg can't set video bitrate
11 mai 2014, par EmanueleWhen capturing input from FFmpeg with following command line :

As you can see the video is being saved with 200kbs no matter what option I set ; what am I doing wrong ?

FFMpeg : no essence (Invalid data found when processing input)

[mxf @ 0x272de60] no essence
/tmp/TEST_4K.MXF: Invalid data found when processing inputThe file is quite large ( 30GB). Could this have something to do with this issue ? I googled for the no essence error but this doesn’t seem to provide any useful information. I checked the permissions on the file and those are not an issue. Also, I tried the same command for a smaller file (approx. 12 GB, which does work). Has anyone had any problems handling large files with FFMpeg ? Thanks !
