HI, I am working on validating Mlp encoder in Libavcodec . I have converted .wav file to .pcm file using acodec pcm_s16le . Now i want to convert .pcm file to .mlp file using mlp encoder which i am working on.
the command line tool i am using is ./ffmpeg -i ~/file.pcm -acodec mlp -b:a 18m -r 29.97 -strict unofficial -sample_fmt s16 ~/final.mlp But i am getting the below error user@user:~/ffmpeg_sources/ffmpeg$ ./ffmpeg -i ~/file.raw -acodec mlp -b:a 18m -r 29.97 -strict unofficial -sample_fmt s16 ~/final.mlp ffmpeg version 2.4.git Copyright (c) 2000-2014 the FFmpeg developers built on Oct 27 2014 22:58:52 with gcc 4.8 (Ubuntu/Linaro 4.8.1-10ubuntu9) configuration: --prefix=/home/soumya/ffmpeg_build --extra-cflags=-I/home/soumya/ffmpeg_build/include --extra-ldflags=-L/home/soumya/ffmpeg_build/lib --bindir=/home/soumya/bin --enable-gpl --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-nonfree --enable-x11grab --cc=c99 libavutil 54. 10.100 / 54. 10.100 libavcodec 56. 9.102 / 56. 9.102 libavformat 56. 9.101 / 56. 9.101 libavdevice 56. 1.100 / 56. 1.100 libavfilter 5. 2.100 / 5. 2.100 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 3.100 / 53. 3.100 [image2 @ 0x3d6ff60] Format image2 detected only with low score of 5, misdetection possible!

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.
