Comment (by jjlee3):

 I found the same problem.
 I modified the ffmpeg/doc/eamples/decoding_encoding.c function
 audio_decode_example to test it.

     assert(codec);
     c = avcodec_alloc_context3(codec);
     assert(c);
     if (avcodec_open2(c, codec, NULL) < 0) { assert(false); }

     outbuf_size = AVCODEC_MAX_AUDIO_FRAME_SIZE;
     outbuf = (uint8_t*)av_malloc(outbuf_size);

     for (int i = 0; i < _countof(audioPacket); ++i) {
         av_init_packet(&avpkt);
         memcpy(inbuf, audioPacket[i].data, audioPacket[i].size);
         memset(&inbuf[audioPacket[i].size], 0,
 FF_INPUT_BUFFER_PADDING_SIZE);
         avpkt.data = inbuf;
         avpkt.size = audioPacket[i].size;

         out_size = AVCODEC_MAX_AUDIO_FRAME_SIZE;
         len = avcodec_decode_audio3(c, reinterpret_cast<int16_t*>(outbuf),
             &out_size, &avpkt);
         assert (len >= 0);
         assert(len == avpkt.size); // only for nellymoser
         assert(c->frame_size);
     }

     av_free(outbuf);
     avcodec_close(c);
     av_free(c);
 }
 }}}

 I always got an assert for "assert(c->frame_size);".
