+Determining the right values to pass to AVCodecContext:
+
+One user [https://lists.ffmpeg.org/pipermail/ffmpeg-user/2012-June/007410.html shared] this advice for determining all the correct values:
+
+ [An] approach to figuring this out is:
+
+ 1. come up with the ffmpeg app command line which does what you want
+
+ 2. use the gdb debugger to execute the ffmpeg_g app, put a breakpoint on avcodec_encode_audio2() (or whichever method you need), and see what values the ffmpeg app uses for AVPacket and for the (audio or otherwise) related fields in AVCodecContext.
