Asterisk Video Playback Issue

Hi All,

I am able to play back recorded video of extension .h264, generated along with .ulaw.
It is very slow while playing back.
I found the link below as a solution but still playback is too slow.
https://issues.asterisk.org/jira/browse/ASTERISK-26554ideo

Can anyone suggest me anything to speed up the playback.

Suggestion for combination of Video coding type along with SIP phones that support the video coding that works well with asterisk to speed up playback will be appreciated.

Regards
Senjam
