[mythtv] More on saa7134 + v4l2
Wed, 06 Nov 2002 23:59:07 +1000
Here is an update on using v4l2-old + saa7134 with mythtv
I have managed to get a picture out of it (used v4lctl to set to
composite input), no code changes were necessary, defining V4L2 was
enough, however if have a couple of issues:
If I use 640x480 the picture is virtually live but it drops 3-5 frames a
second using both rtjpeg or mpeg4 (I have a Duron 1.2 and rtjpeg uses
less than 10%)
Using 320x240 I get no dropped frames but the picture lags the actual
feed by about 5 seconds.
X is running at 640x480 using the Nvidia NVdriver binary driver.
Specifying a resolution somewhere in between will cause a seg fault most
of the time, especially if the aspect is wrong.
I am using todays CVS.
Any suggestions are welcome.
