So for example: I have file.mp3, I know that my desired format can play sound with out video (for example FLV) so how to put encoded mp3 data using ffmpeg from mp3 container into flv (where to get articles/code samples on this)?
I mean not from cmd but from C++ using ffmpeg as library. (see tags)
Here is the command to convert .mp3 file to .flv(which does not have any video data).
ffmpeg -i test.mp3 -ab 32k -acodec libmp3lame -ac 1 -ar 44100 audio.flv.
You can execute this command from your program.
If you need help on how to install and use ffmpeg you can go to their site:
http://ffmpeg.org
