input/output raw rtp packet api about aiortc

[jlaine]

I'm not sure outputting the raw RTP is very useful, how would things like RTCP reports be handled/generated? Maybe you can elaborate on your usecase?

In the meantime if you absolutely want to do this, one way would be to monkey-patch RTCRtpReceiver._handle_rtp_packet and RTCRtpReceiver._handle_rtcp_packet which will give you the decoded RTP/RTCP packets. If you want to convert them back to bytes you can use bytes(packet).

Alternatively, you could also monkey-patch RTCDtlsTransport._handle_rtp_data and RTCDtlsTransport._handle_rtcp_data but then you will have to handle routing to the correct RTP receiver yourself.

user case like: save to file, forward to rtsp server without another decode/encode.

monkey-patch is way to do this.

Saving to file: ok, sure.

As to forwarding to another server, I'm not sure this would be the right place to do it. I agree you want to skip the codec decode/encode step, but I think you would still like to retain the benefit of the jitter buffer and the RTCP-based retransmission (which I'm currently implementing). For this usecase I think it would be more useful to have an API which hands you re-assembled (but not decoded) audio/video frames.

Anyway I'll close this issue for now, please do leave a comment if you have some additional feedback.

RTPReceiver still do rtcp-based retransmission and jitter buffer, just pass out the rtp packet after we got a full frame. like this line https://github.com/jlaine/aiortc/blob/master/aiortc/rtcrtpreceiver.py#L236
