play PCM audio

bendeguy — Mon, 07 Aug 2006 23:33:17 GMT

Hi!

I would like to play a pcm audio data. I haven't got any header just the data. I know it's bitrate is 64kbit/sec and a sample is 8 bit. Is there any simple way to play it (similar to the MJPEGVideo Decoder example)?

A program continuosly sending me Mpeg4 video data and PCM audio. I have to deocde the video and send it back to the program. I've solved this part. But I have to play the audio and this is my problem. Please help. Thanks in advance:

Hi Bendeguy,

we do not have such a special sample, but actually I should not be too difficult as you have almost all needed information about your data. Take a look on MSDN description for WaveOut function.

I also recommend you to take a look on IPP media sample, which is not so simple as you probably want, but it do that job. See simple_player.cpp, avsync.cpp and codec_pipeline.cpp files
