After running 0.16 from RPMs for a while, I got bold and decided to rebuild my own from CVS. I have an Athlon XP 1800+ CPU and set the -march=athlon-xp. I read about some people in the past having slower performance with this flag over pentiumpro, but it's been a long time since anyone recently complained of this, so I figured I'd try it.
The problem I'm having is this. I start watching TV, and everything is just fine. If I stay on the channel, it's fine. If I switch channels, the next channel starts off fine, but about 4 seconds later, the video gets choppy. The audio is flawless. The video stutters, like I'm only seeing every nth frame. It's consistent, it doesn't seem to get better or worse with time. I'm guessing this is a capture issue and not a decoding issue, because when I rewind live TV and watch from the buffer, it is choppy in the same way. Maybe that's an ignorant statement, possibly when I watch live TV I'm just watching from the buffer anyway, I don't know. I'm using a Hauppage 250 card and I'm using an FC3 build following Jarod's guide, except I decided to build all the myth modules myself. I have a 5200FX video card, enabled OpenGL on all builds that had the option, and am NOT using XvMC. I tried a build with XvMC, and got the weirdest distortions in the video. Looked like a psychodelic trip. I'm seeing this in mythfrontend.log: 2005-02-04 12:01:11.123 GetNextFreeFrame() served a busy frame. Dropping. #Frames=38/31. 2005-02-04 12:01:11.128 GetNextFreeFrame() served a busy frame. Dropping. #Frames=37/31. 2005-02-04 12:01:11.128 GetNextFreeFrame() served a busy frame. Dropping. #Frames=36/31. I see nothing in my mythbackend log that pertains. I'm open to any suggestions. Thanks, Larry
