FFmpeg: Decoding
https://ffmpeg.org/doxygen/0.11/group__lavc__decoding.html
Use avcodec_alloc_frame to get an AVFrame, the codec will allocate memory for the actual bitmap. with default get/release_buffer(), the decoder frees/reuses the bitmap as it sees fit. with overridden get/release_buffer() (needs CODEC_CAP_DR1) the user decides into what buffer the decoder decodes and the decoder tells the user once it does not need the data …

http://wiki.aasimon.org/doku.php?id=ffmpeg:avcodec_decode_video
The avcodec_decode_video () function decodes a video frame from the input buffer buf of size buf_size. To decode it, it makes use of the video codec which was coupled with avctx using avcodec_open (). The resulting decoded frame is stored in picture. Warning: The input buffer must be FF_INPUT_BUFFER_PADDING_SIZE larger than the actual read bytes because …

Use av_read_frame() to read individual audio packets from the muxing format, and feed the resulting AVPacket into the decoder using avcodec_decode_audio4(). See e.g. the dranger api tutorial. I know api-example.c uses the above code, but that unfortunately only works for a very limited subset of cases.

Strange, avcodec_decode_audio3 calls avcodec_decode_audio4, see util.c. Are you sure that input buffer is of sufficient size and not underunning? Also, does it fail on the first or the second decode call, or sometime later? –
