dear teams, I have been trying to generate video and audio streams with ffmpeg.exe command line without success; does anyone know what codecs and formats association or MXF xml dict file to use ? my code looks like this : I have a multilingual MPEG2-TS input file that I need to remux into MXF Code: ffmpeg -i input_VAA.ts -vcodec mpeg2video -an -f mp2 video_V.mpg
ffmpeg -i input_VAA.ts -map 0:1 audioFRA_A.wav ffmpeg -i input_VAA.ts -map 0:2 audioENG_A.wav mxfwrap.exe -f video_V.mpg+audioFRA_A.wav+audioENG_A.wav output_VAA.mxf the output always turns to "ERROR: Could not identify the essence in file video_V.mpg" in advance, thank you Cedric |

I think video extraction is wrong : Probably something like this will work better : ffmpeg -i input_VAA.ts -vcodec copy -f mpeg2video video_V.m2v Need elementary stream for mxflib. (-f mpeg2video) and -vcodec copy takes the stream out without recompressing. .m2v extension is probably needed also. |
