Here you will find all sources I have tested last days.
Logitech C525 is a very good Webcam HD that can give RGB24 (no need to decode Mjpeg) many modes up to 1600x896p 30 fps.
with autofocus and for 35 euros...
1024x576 is the real format display correspond to D1- 16/9 and don't need too much CPU power for software encoding.
1280x720 is my own preference...
about picture quality:
* using SR4000 is too low for HD higher than 720p-mpeg2 coding ,but can be used for H264
(good result with HDV camera firewire input 1440x1080i or C525 webcam with 1600x896p setting)
* with SR4000, mpeg2 can be used up to 1280x720p with good video
* with SR1500 or lower, H264 allow to keep good video. for this rate ,IMHO, Mpeg2 should be discarded.
I understand that for the moment many OM use satellite setTop Boxes that don't allow H264 decoding but if we use last dvb-S2 setTop box or a PC we can have H264 decoding possibilities.
same problem using SCART output that can't give progressive formats....
The last version of Tutioune in beta test allow to receive H264, even in full HD 1920x1080 with the mini Itx GA-D525 TUD motherboard with little Atom D525 under win XP.
( see TiouneBox description that can be 12v powered with a settop-Box look)
I am now testing the Elecard G4 SDK that give us all directshow filters we need.
I have tested Elecard Multiplexer. It runs well and can be used with no restriction for transmission.
I have to test now Elecard coder and other free coder we can find.
Perhaps some of you have already done this job and can give their results.

this morning I will send Digilite H264 HDV pictures received by Tutioune on my TiouneMonitor http://www.vivadatv.org/tutioune.php?om ... ation_id=2
