Hi All, I am new to ffmpeg library and modified muxing.c demo (written by Fabrice Bellard) so I gather audio from a file using libsndfile and create frames (based on audio) in AV_PIX_FMT_RGB24 format. It currently encode the stream pix format with AV_PIX_FMT_YUV420P.
Here's my code: http://www.oifii.org/ns-org/nsd/ar/cp/audio_spi/spiffmpegmuxingspectrum_qt2016/spiffmpegmuxingspectrum_qt2016.c My question is: How can I encode lossless .mp4? Do I have to change the stream pix format to AV_PIX_FMT_RGB24? Do I have to install a codec that support that pix format?
