[mythtv] DVB: Nexus-s w/PBSHD & framerate

Is it even possible to turn that flag off for FF cards? When I turn off that
option I get the standard 15 second timeout message unless I turn off wait
for sequence start, which then gives me no video.

 

I'm using svn 7607.

Another thing I always notice is that audio and video are ways out of sync,
even with SD content until I pause/unpause. This doesn't seem to happen with
a budget card.

I've done some searching around getting HD content on my Nexus-s using
MythTV but have never been entirely successful. The video is choppy and
garbled most of the time with short periods of perfect video. I assumed this
was due to limitations of the card. However, people are reporting success
with vdr/softdevice on a Nexus-s by altering DEFAULT_FRAMETIME in
mpeg2decoder.h from 400 to 0.

 

I started digging into Myth to see if I could reproduce that and found that
when the picture was good, fps was at 29.98/29.98. However, when the picture
started garbling it went down to half that. I'm unable to figure out why. 

 

Has anyone had success with PBSHD on AMC3 with a Nexus-s?

Yes, I have Nexus mythtv-svn working with PBS-HD on AMC3.  Works pretty much
100%.

 

I found the hardware decoder of the card can not keep up with the high bit
rate for the single HD stream (or that's what I suspect).  Check to make
sure you have "Using hardware MPEG decoder" turned OFF in "mythtv-setup /
Capture Cards / DVB : 0 / Recorder Options".
