[OpenSIPS-Users] h264 webrtc and opensips

Thanks for getting back to me. I was afraid of this as I didn't see any options in rtpengine that supported video codecs either. We are trying to upgrade some of our devices to support packetization-mode 0 and 1.

Hi, Ryan!

I don't have that much experience with H.264, but my first instinct was to look into the rtpengine packetization feature. But unfortunately rtpengine does not support H.264 codecs, so I doubt this can help. But perhaps you could look into different transcoding solutions that do support H.264 transcoding.

Best regards,
