Hi All,

We have developped some components for MythTV that we needed to enable 
IP streaming and H264 video. We have submitted them as enhancement 
tickets to the MythTV project. If someone is interrested to try these 
new features you can take a look at ticket #1787 and #1788. Here is a 
short description of the two patches. More detailed documentation can be 
found in the Doxygen documentation of the new files and in the readme 
included with each patches.

Ticket #1787 - IP Network Recorder
This patch contains a IP Network MPEG-TS recorder. This new type of 
"Capture Card" will record MPEG-2 Transport Stream feeds over UDP/IP. It 
is possible to use this input with MPEG1/2/4 video. It can also support 
H264 video with the h264_tools patch.

Ticket #1788 - H264 tools
This patch contains a set of tools needed to enable H264 support in 
MythTV. It contains a minimalist state machine class used to detect 
H.264 keyframes. A usage example is included in the IP Network Recorder 

After installing these two patches, it is possible to record streamed 
MPEG2-TS over UDP/IP encoded in MPEG1/2/4 or H.264. We have used VLC 
0.8.5 (www.videolan.org) to test these functionnalities.

Comments are welcome,
