Comment (by vijm1972):

 Hi Team,

 Having same issue while transcoding from audio.mxf to mp3. My source file
 is created using Clipster IMF package creation. We have separate audio and
 video streams in IMF package. We need to transcode audio.mxf to mp3 using
 FFMPEG. I am getting below error message after processing.

 versi
 on to the newest one from Git. If the problem still occurs, it means that
 your file has a feature which has not been implemented.
