Hello, i am not really a C-developer so my question is: i call ffmpeg only with an input file "xxx.mmf" for some smaf files i see the rate / bitrate / Hz and so on ... but for a lot of files i see the following message: [mmf @ 0x40090d6c]Unsupported SMAF chunk 0552544d what it means and how can i fix it. Thanks for a response, Joerg
