I just upgraded from FC1 where I didn't have any problems with tvtime at all. After upgrading I too an seeing the picture fade to black (more like 99% black for me). This happens with XDS on or off, doesn't make a difference. I see the following error on the command line when the screen goes black: videoinput: Can't read frame. Error was: Input/output error (975). In addition the following errors are logged to syslog: May 20 10:47:04 penguin kernel: bttv0: timeout: drop=227 irq=75976/75976, risc=24d5b07c, bits: VSYNC HSYNC OFLOW FDSR May 20 10:47:04 penguin kernel: bttv0: reset, reinitialize May 20 10:47:04 penguin kernel: bttv0: PLL can sleep, using XTAL (28636363). After removing tvtime and installing the package I used on FC1, which I obtained from the DAG Weirs repo filename tvtime-0.9.12-0.rhfc1.dag.i386.rpm I found the problem is still there. This indicates to me that the problem is in the bttv, v4l, tvtuner or related driver, not in the tvtime application. However, on another system that was an FC1 -> FC2 upgrade that still had the xawtv application I had no trouble at all with xawtv yet tvtime would go black after a few seconds. There is a long-standing problem with the version of bttv that ships in 2.6 kernels where the card will reset itself if you use the VBI device and capture video in tvtime. The problem does not exist in bttv 0.7 that was shipped with 2.4 kernels. It was reported to the bttv maintainer before 2.6 shipped, but he cannot reproduce it and the bug still exists. When bttv resets, all of the colour controls are reset to random values, resulting in a usually black or red screen. The only known workaround at this time is to not use XDS or closed captions in tvtime. If you can at all help with the debugging of this problem, please contact the bttv maintainer (see http://bytesex.org/bttv/). ok, it's a bug in bttv drvier. reassign to kernel. what kernel version is this ? |
