Hi all, I recently switched ffmpeg from version 1.x to 3. Now I got some warning when I transcoding MXF files to youtube compliant MP4s.
command: ffmpeg -y -i file.mxf -filter:v yadif -b:v 8000k -minrate 8000k -maxrate 8000k -bufsize 4000k -vcodec libx264 -flags +cgop -pix_fmt yuv420p -f mp4 -filter_complex "amerge,volume=14.4dB [aout]" -map [aout] -c:a libfdk_aac -b:a 384k -ac 2 -ar 48000 -cutoff 20k -movflags faststart -ss 00:00:00 file.mp4 warnings: Codec AVOption bf (set maximum number of B frames between non-B-frames) specified for output file #0 (file.mp4) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream. [mp4 @ 0x39156b0] Using AVStream.codec to pass codec parameters to muxers is deprecated, use AVStream.codecpar instead.
