The MXF _file format_ is essentially a series of KLV packets. Yes it is possible to add additional KLV packets. You would need to modify libavformat/mxf*. However I am unware of any systems capable of processing such files. > Is KLV from user supported in any other formats (mpeg-ts) ? Yes FFmpeg mpegts muxer and demuxer supports this. Also samples here: http://samples.ffmpeg.org/MPEG2/mpegts-klv/ > Are you familiar with other methods or libraries that support KLV from user ? No. -- Peter (A907 E02F A6E5 0CD2 34CD 20D2 6760 79C5 AC40 DD6B)
