aiortp

Very, very pre-alpha software. Buyer beware!

RTP and basic SDP support for AsyncIO written in pure Python/Cython.

Seems to have good performance charactistics when playing static audio samples.

Lots of work needing to be done, has a horrible API, and need to explore if a pure playback loop in pure C without the GIL will improve performance.

Built with a focus of SIP testing, but I do hope to build something more general purpose out of the base.

Example

# Create the scheduler and attach a stream
rtp_scheduler = aiortp.RTPScheduler()
rtp = rtp_scheduler.create_new_stream((local_ip, 49709))

# Get the SDP and send an invite off
payload = rtp.describe()
headers['Content-Type'] = 'application/sdp'
response = send_invite(headers=headers, payload=payload)

# Then feed in the SDP from the 200 OK
rtp.negotiate(response.payload)

# Start playback
await rtp.start('some_audio_sample.flac')

# Wait for the audio sample to finish playback
await rtp.wait()

TODO

• Expose the received RTP stream
• DTMF
• Comfort noise
• More codecs
• Better SDP support
• Jitter buffer and RTP statistics (jitter, etc.)
• Support for other operating systems
