There is noting else we can do to help you out, since you provide little
valuable information.
OK, firstly make sure that you already registered the codecs.
check the API avcodec_register_all()

Hi List,
I write live transcoder for our IP-cameras, in some cases audio straem also
need to transcoder.
But I have a problem with non-equal frame_size in input codec context and
output codec context:
1. I read audio packet
2. I decode it with avcodec_decode_audio4()
It provides AVFrame's with nb_
Hi,
My avcodec_find_encoder(CODEC_ID_THEORA) returns null ptr
Is there anywhere I can check why this encoder is not supported?
Thanks!

do i need to unregister when there is no need of ffmpeg or before the
program exit?

Hey Carl,
thank you for your hint! With that I was able to create a video stream, an
audio stream and muxed them into a file.
But I guess I was too naive to think that I could decode the frames and encode
them back to file as they come in without setting new presentation time stamps
and so on.
Call av_register_all() only at the beginning of your main program, not before
each open file; but, depending on what you are doing, you may also need to call
avcodec_register_all() and/or avfilter_register_all(). Refer to the
documentation if you’re not sure what each does.

Hey all,
I'm trying to write a simple program which decodes the video and audio frames
and encodes and mux it back to a file.
How can I generally accomplish that?
decoding and encoding the videostream for itself works.
decoding and encoding the audiostream for itself works.

Look in doc/examples/muxing.c and search for "global" in it.
