Do you know what video codec is used for messengers?
I'd like to know the video codec 开发者_Python百科used for MSN, yahoo, QQ or any other XMPP messengers.
Thanks for help.
For video codecs it's something like this:
- Skype: On2's VP7.
- Yahoo! Messenger: JPEG 2000, i.e. only I-frames.
- Google talk: H264 and others.
- MSN Messenger: Siren Codec.
- iChat: H.264/AVC.
