Examples of com.xuggle.xuggler.IStreamCoder.encodeAudio()

com.xuggle.xuggler.IStreamCoder.encodeAudio()
Encode the given samples using this StreamCoder. The VideoPicture will allocate a buffer to use internally for this, and will free it when the frame destroys itself. Callers should call this repeatedly on a set of samples until we consume all the samples. Also, when done in order to flush the encoder, caller should call this method passing in 0 (null) for pSamples to tell the encoder to flush any data it was keeping a hold of. @param pOutPacket [out] The packet to encode into. It will point to a buffer allocated in the frame. Caller should check IPacket::isComplete() after call to find out if we had enough information to encode a full packet. @param pSamples [in] The samples to consume @param sampleToStartFrom [in] Which sample you want to start with This is usually zero, but if you're using a codec that packetizes output with small number of samples, you may need to call encodeAudio repeatedly with different starting samples to consume all of your samples. @return number of samples we consumed when encoding, or negative for errors.
