#7883: Problems in LiveTV with analog card (BT878)
--------------------------------------+-------------------------------------
Reporter: andrew@… | Owner: ijr
Type: defect | Status: new
Priority: minor | Milestone: unknown
Component: MythTV - General | Version: 0.22-fixes
Severity: medium | Mlocked: 0
--------------------------------------+-------------------------------------
When I start live TV in EPG mode with an analog channel configured as
starting channel I get a small preview picture OK, though without sound.
If I go to full screen, or move to another analog channel in EPG, I get an
error message saying "Irrecoverable recorder error". Sometimes I get a few
seconds of full screen video, but other times mythfrontend crashes. See
logs below - there appears to be a problem with audio capture, don't know
if it is related to the video playback problem.
This card has worked fine previously on 0.21 using OSS audio capture
device names, and works fine now in xawtv or tvtime. The following command
pipes analog TV sound to HDMI audio, which shows that it is the correct
capture device name and it is working properly:-
{{{
arecord -D hw:3,1 -r 119466 -f S16_LE | aplay -D plughw:2,3
}}}
DVB-T, DVDs, video files etc. all work fine in MythTV, and setting Audio
Output Device to "ALSA: plughw:2,3" sends sound to HDMI audio without
problem. I can play back the .nuv file in mplayer, though without sound -
sound is not being captured, not just not played back.
The analog card is BT878 (Hauppauge WinTV Go!). System is Fedora 11
(kernel 2.6.30.10-105.fc11.x86_64). I have removed Pulseaudio.
