I have been trying to create a source client for ice cast for ios. I have been able to connect using asyncsocket to connect to the socket. I am also able to write data to the server. The icecast configuration is done for mp3 format. But the mp3 file written to the server is corrupt. I am providing some code snippets.
Header:
NSString *string = @"SOURCE /sync HTTP/1.0\r\n"
"Authorization: Basic c291cmNlOmhhY2ttZQ==\r\n"
"User-Agent: butt-0.1.12\r\n"
"User-Agent: butt-0.1.12\r\n"
"content-type: audio/mpeg\r\n"
"ice-name: sync's Stream\r\n"
"ice-public: 0\r\n"
"ice-genre: Rock\r\n"
"ice-description: This is my server description\r\n"
"Connection: keep-alive\r\n"
"ice-audio-info: ice-samplerate=44100;ice-bitrate=48;ice-channels=2\r\n\r\n";
NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding];
//sending http request to write the header
NSLog(@"Sending HTTP Request.");
[socket writeData:data withTimeout:-1 tag:1];
//write buffer data to server
[socket writeData:self.dataBuffer withTimeout:-1 tag:1];
for recording i am using aqrecorder using the following code to record it.
void AQRecorder::MyInputBufferHandler( void * inUserData,
AudioQueueRef inAQ,
AudioQueueBufferRef inBuffer,
const AudioTimeStamp * inStartTime,
UInt32 inNumPackets,
const AudioStreamPacketDescription* inPacketDesc)
{
AQRecorder *aqr = (AQRecorder *)inUserData;
try {
if (inNumPackets > 0) {
// write packets to file
XThrowIfError(AudioFileWritePackets(aqr->mRecordFile, FALSE, inBuffer->mAudioDataByteSize,
inPacketDesc, aqr->mRecordPacket, &inNumPackets, inBuffer->mAudioData),
"AudioFileWritePackets failed");
aqr->mRecordPacket += inNumPackets;
NSLog(@"size = %u",(unsigned int)inBuffer->mAudioDataByteSize);
data = [[[NSData alloc]initWithBytes:inBuffer->mAudioData length:inBuffer->mAudioDataByteSize]retain];
server *srv = [[server alloc]init];
srv.dataBuffer=data;
[srv connecting];
}
// if we're not stopping, re-enqueue the buffe so that it gets filled again
if (aqr->IsRunning())
XThrowIfError(AudioQueueEnqueueBuffer(inAQ, inBuffer, 0, NULL), "AudioQueueEnqueueBuffer failed");
} catch (CAXException e) {
char buf[256];
fprintf(stderr, "Error: %s (%s)\n", e.mOperation, e.FormatError(buf));
}
}
void AQRecorder::StartRecord(CFStringRef inRecordFile)
{
// server *srv=[[server alloc]init];
// [srv connecting];
int i, bufferByteSize;
UInt32 size;
CFURLRef url = nil;
try {
mFileName = CFStringCreateCopy(kCFAllocatorDefault, inRecordFile);
// // specify the recording format
// SetupAudioFormat(kAudioFormatMPEG4AAC);
// specify the recording format, use hardware AAC if available
// otherwise use IMA4
if(IsAACHardwareEncoderAvailable())
SetupAudioFormat(kAudioFormatMPEG4AAC);
else
SetupAudioFormat(kAudioFormatAppleIMA4);
// create the queue
XThrowIfError(AudioQueueNewInput(
&mRecordFormat,
MyInputBufferHandler,
this /* userData */,
NULL /* run loop */, NULL /* run loop mode */,
0 /* flags */, &mQueue), "AudioQueueNewInput failed");
// get the record format back from the queue's audio converter --
// the file may require a more specific stream description than was necessary to create the encoder.
mRecordPacket = 0;
size = sizeof(mRecordFormat);
XThrowIfError(AudioQueueGetProperty(mQueue, kAudioQueueProperty_StreamDescription,
&mRecordFormat, &size), "couldn't get queue's format");
NSString *recordFile = [NSTemporaryDirectory() stringByAppendingPathComponent: (NSString*)inRecordFile];
//url = CFURLCreateWithString(kCFAllocatorDefault, (CFStringRef)recordFile, NULL);
url = CFURLCreateWithFileSystemPath(kCFAllocatorDefault, (CFStringRef)recordFile, kCFURLPOSIXPathStyle, false);
// create the audio file
OSStatus status = AudioFileCreateWithURL(url, kAudioFileCAFType, &mRecordFormat, kAudioFileFlags_EraseFile, &mRecordFile);
CFRelease(url);
XThrowIfError(status, "AudioFileCreateWithURL failed");
// copy the cookie first to give the file object as much info as we can about the data going in
// not necessary for pcm, but required for some compressed audio
CopyEncoderCookieToFile();
// allocate and enqueue buffers
bufferByteSize = ComputeRecordBufferSize(&mRecordFormat, kBufferDurationSeconds); // enough bytes for half a second
for (i = 0; i < kNumberRecordBuffers; ++i) {
XThrowIfError(AudioQueueAllocateBuffer(mQueue, bufferByteSize, &mBuffers[i]),
"AudioQueueAllocateBuffer failed");
XThrowIfError(AudioQueueEnqueueBuffer(mQueue, mBuffers[i], 0, NULL),
"AudioQueueEnqueueBuffer failed");
}
// start the queue
mIsRunning = true;
XThrowIfError(AudioQueueStart(mQueue, NULL), "AudioQueueStart failed");
}
catch (CAXException e) {
char buf[256];
fprintf(stderr, "Error: %s (%s)\n", e.mOperation, e.FormatError(buf));
}
catch (...) {
fprintf(stderr, "An unknown error occurred\n");;
}
}
Do i need to change the format to write to the server?
