I am now using APS-DIRECT. > First of all, the aps-direct branch is supposed to be an internal branch and we're not quite finished with it so expect few rough edges here and there. Even the API is not quite finalized yet, so it's really not ready to be used for anything. But I do appreciate, and surprised at the same time, with the level of interests that this has generated. Answering your question. When using APS-Direct, you always need to remember that the whole point of having APS-Direct is to enable codec compression in sound device (APS/VAS), hence to let encoded frames flowing end-to-end from the microphone down to the socket and vice versa. The sample on_stream_created() snippet shows how to open the sound device in codec format according to the codec being used by the call. So since the sound device is opened in codec mode, you can't no longer feed it with PCM frames (e.g. the tone generator). To use the tone generator (or any other pjmedia features that works on PCM frames such as WAV files), you will need to open the sound device in PCM mode to play the ring tones, then when you want to communicate with the call/stream, you will need to close the sound device, and re-open it using the codec that is used by the call. The on_stream_created() snippet currently doesn't show how to do this, so you need to do it yourself. cheers Benny -------------- next part -------------- An HTML attachment was scrubbed...
