Hi, I'm using ffmpeg libav library for live streaming via RTMP. I want to know how to give my choice of audio and video codec for the particular format in avformat_alloc_output_context2.
In Detail: The following command works perfectly for me. ffmpeg -re -stream_loop -1 -i ~/Downloads/Microsoft_Surface.mp4 -vcodec copy -c:a aac -b:a 160k -ar 44100 -strict -2 -f flv -flvflags no_duration_filesize rtmp://192.168.1.7/live/surface In the output, I have set my audio codec to be aac and copied the video codec from input, which is H264. I want to emulate this in the library, but don't know how to. avformat_alloc_output_context2, with parameter format name as "flv", sets oformat audio codec to ADPCM_SWF and video codec to FLV1. How to change that to AAC and H264 ? So far, used av_guess_format to construct AVOutputFormat. It accepts only format as input. And I don't know where to mention audio and video codec. Also tried giving filename to avformat_alloc_output_context2 with the rest of the parameters NULL. The file has AAC audio and H264 video. But still ffmpeg loads oformat with ADPCM_SWF audio and FLV1 video codecs. Any hint/guidance is hugely appreciated. Thank you.
