Hi,

In GPUMovieWriter.m:450 after for (int bufferCount=0; bufferCount < audioBufferList.mNumberBuffers; bufferCount++) { SInt16 *samples = (SInt16 *)audioBufferList.mBuffers[bufferCount].mData; self.audioProcessingCallback(&samples, numSamplesInBuffer); }

You should release CMBlockBufferRef with CFRelease(buffer);

If you don´t do this, after X audio samples buffer processed the system stops filling AudioBufferList with the retained block buffer information
