Buffer error in avcodec_decode_audio4()

问题:

I have upgraded my ffmpeg version to the latest commit and Now I can see that the audio decoding funciton avcodec_decode_audio3 has been deprecated and when I use the new function avcodec_decode_audio4, as per the changes required in it, I get the error as

[amrnb @ 003a5000] get_buffer() failed.

I am not able to find what causes this error. Anyone has a sample example of usng this new function:

avcodec_decode_audio4((AVCodecContext *avctx, AVFrame *frame,int *got_frame_ptr, AVPacket *avpkt);

回答1:

Check decoding_encoding.c example from ffmpeg source. It uses function avcodec_decode_audio4.
