mythtv can not work with HW MPEG2 encoder of AUSU PVR-416
|
|
Dear mythtv fans,
I am using a AUSU PVR-416 card with mpeg2 encoder to improve the TV program quality. It is said to be compatible with AVerMedia_M150-D according to the wiki.
However, mythtv failed on either Live TV or record. I am using the module driver and firmware provided by 2.6.24-24, and I have tested that either of the following actually works fine:
cat /dev/video1 > foo.mpg # this generate a valide mpeg2 file.
mplayer /dev/video1
The video quality is very good, although not voice yet. I am very puzzeld why the mpeg2 can be accessed directly without any error, while mythtv can not work with it? I have noticed that mythbackend requires 'ivtv' driver, however, on ivtv's wiki, it says the drive won't work with AUSU PVR-416.
Anyone has idea on how to make it work? thanks very much,
Clark
