What is the default video codec in WebRTC?How can I change this?

There is no default video codec in WebRTC. You always have a choice. The API allows developer to change the video/audio codec.

Really, please show me the way to change video codec in webrtc.I used Libjingle peerconnection.

I want to use h.264 codec instead of VP8 :d

[ArikYa]

Due to licensing limitations, H.264 in WebRTC is only available on devices that support H.264 hardware acceleration. Right now it is hard coded to support only devices that use Qualcomm chipsets, except the Galaxy S4 (due to some specific issues on that phone).

I know that, but I have some special reason to use h.264.Please help

[ArikYa]

What device are you using? If the device supports H.264 using hardware, but it isn't Qualcomm based, you can always get WebRTC sources and add that chipset to the list of supported devices

I just want to know how to use H.264 in libjingle_peerconnection lib.I dont care about supported devices. Just how to coding for this

[ArikYa]

Not sure I'm following you. If you are using unsupported devices, you can only do VP8. If you are using supported devices, you need to prefer H.264 in the SDP, because the preferred codec is VP8 even when H.264 is supported. Please elaborate more about what you are trying to do

Thanks @ArikYa. How to prefer h264 in sdp? It is a little experiment.
