xine-hd locks up after a few minutes but...

Whenever I run xine-hd from the command line like:
Code:
xine -C[channel X] dtv://
I get a 50-50 chance of getting the audio and video to work at standard definition, but any interference received will crash xine. Any 780p or 1080i just wont even start, I just get a blank window in xine. But if I use
Code:
getatsc /dev/dtv. "channel X" > x.vid
and then in a different terminal window
Code:
xine x.vid
it will play anything that getatsc will put out, even 1080i content will play without dropping any frames and any interference just messes up a frame of video and keeps on going like nothing happened. I have a dual athlonMP 2200+ with a GeForce 6800 running xine-hd with xvmc active.. Is this just some immaturity in xine-hd or am I doing something wrong? I could care less about storing video on my hard drive. I just want to watch hdtv without filling up my hard drive.

Have you tried "xine -V xvmc" to be totally sure it's using XvMC?

Try running "xine --verbose=8" to see how far xine is getting.

I did try running xine with the "-V xvmc" option, but that made no difference. With standard definition video I can get it working until the station drops it's signal for less than a second about every few minutes. When ever I have getatsc save the stream to a file and have xine play that file, xine will just mess up the video a bit when the station drops and keep on playing the rest of the video. When I run "xine -V xvmc dtv://" standard def video will run just fine for a while until the signal drops for a bit and the video will just loop the same three frames at about 1 frame per second indefinitly. --verbose=8 prints this out whent he error happens:
Code:
 demux error! transport error
demux error! transport error
demux_ts: PID 0x0014: unexpected cc 7 (expected 4)
demux_ts: PID 0x0011: unexpected cc 13 (expected 12)
liba52:a52 frame failed crc16 checksum.
video_out: throwing away image with pts 8756899 because it's too old (diff : 10068).
video_out: throwing away image with pts 8798010 because it's too old (diff : 15391).
video_out: throwing away image with pts 8838161 because it's too old (diff : 20687).
video_out: throwing away image with pts 8878858 because it's too old (diff : 24891).

When ever I try to get any 780p or 1080i video with "xine -V xvmc dtv://" I just get a blank screen and --verbose=8 mode will just print out "demux error! transport error" repeatedly. Dtvsignal shows that every digital station in my area has about 90~95% signal strength, so I don't think it is an issue with bad reception. The signal dropping I described before is from the transmitter as people I know who have an HDTV have noticed the occasional video corruption every few minutes with that station.

It's almost certainly a problem with your reception. You are probably experiencing multipath. This can be causing by passing vehicles and other unpredicable conditions. I had a problem just like this until I figured out my breakups were caused by a bus going down a street.

If the station's transmitter is dying, you better give them a call and tell them to fix it. You won't be able to fix it on your end.

In any case, xine will never be able to play a stream that's this corrupted.

Bullshit -- that is not acceptable. TVs don't crash and require power cycling when they receive a bad stream. They wait until they get a good stream then they display it just fine.

I really home that some effort is getting put into making a movie player that can handle occassional stream corruption...

Not bullshit, It's a fact. If you don't like it, go to the xine homepage and enter it as a bug.

Your computer is not a TV. ATSC receivers don't crash because companies spend millions of dollars designing a specific piece of hardware to receive ATSC without crashing. Well, actually they do crash but have a built-in timer to automattically reset themselves. And they don't "wait until they get a good stream:. They just display garbage or a "waiting to acquire signal" message. And if you think STB's don't lock up, you must have bought one of the more recent models.

And give it away for free like xine? Rolling Eyes

I get occasional corruption when a plane flies over. xine and mplayer almost always recover from it. If you can't receive a station without getting a bad packet every minute, you are much better off watching it with an ATSC STB with a fourth generation receiver. This will cost somewhat more than the HD-3000.
