Iphone Streaming and playing Audio Problem
20 août 2011, par KayKayI am trying to make an app that plays audio stream using ffmpeg, libmms.
I can open mms server, get stream, and decode audio frame to raw frame using suitable codec.
However I don't know how to do next.
I think I must useAudioToolbox/AudioToolbox.h
and make audioqueue.
but however when I give audioqueuebuffer decode buffer's memory and play, Only plays the white noise.
Here is my code.What am i missing ?
Any comment and hint is very appreciated.
Thanks very much.while(av_read_frame(pFormatCtx, &pkt)>=0)
{
int pkt_decoded_len = 0;
int frame_decoded_len;
int decode_buff_remain=AVCODEC_MAX_AUDIO_FRAME_SIZE * 5;
if(pkt.stream_index==audiostream)
{
frame_decoded_len=decode_buff_remain;
int16_t *decode_buff_ptr = decode_buffer;
int decoded_tot_len=0;
pkt_decoded_len = avcodec_decode_audio2(pCodecCtx, decode_buff_ptr, &frame_decoded_len,
pkt.data, pkt.size);
if (pkt_decoded_len <0) break;
AudioQueueAllocateBuffer(audioQueue, kBufferSize, &buffers[i]);
AQOutputCallback(self, audioQueue, buffers[i], pkt_decoded_len);
if(i == 1){
AudioQueueSetParameter(audioQueue, kAudioQueueParam_Volume, 1.0);
AudioQueueStart(audioQueue, NULL);
}
i++;
}
}
void AQOutputCallback(void *inData, AudioQueueRef inAQ, AudioQueueBufferRef inBuffer, int copySize)
{
mmsDemoViewController *staticApp = (mmsDemoViewController *)inData;
[staticApp handleBufferCompleteForQueue:inAQ buffer:inBuffer size:copySize];
}
- (void)handleBufferCompleteForQueue:(AudioQueueRef)inAQ
buffer:(AudioQueueBufferRef)inBuffer
size:(int)copySize
{
inBuffer->mAudioDataByteSize = inBuffer->mAudioDataBytesCapacity;
memcpy((char*)inBuffer->mAudioData, (const char*)decode_buffer, copySize);
AudioQueueEnqueueBuffer(inAQ, inBuffer, 0, NULL);
