Fails to catch Xv errors properly with fglrx driver

[Andreas Oberritter]

This bug report comes initially from democracyplayer, but it seems that it's not democracy's fault.

Binary package hint: democracyplayer

After pressing the play button to watch a downloaded video, the program first froze and then crashed after a short delay.

It seems from the backtrace that X is crashing while trying to query your driver's XVideo capabilities. Does playing video work at all with libxine? Programs that use libxine include totem (with the totem-xine backend package) and the xine player itself. Can you use the open-source "ati" drivers, and if so, does democracyplayer work with them?

[Andreas Oberritter (mtdcr)]

X continued to run. I can play video using vlc and totem-gstreamer (although the last one shows weird colors), but not with xine or totem-xine. I can't even start them without a video file. xine produces the following output:

This is xine (X11 gui) - a free video player v0.99.5.
(c) 2000-2007 The xine Team.
X Error of failed request: BadMatch (invalid parameter attributes)
  Major opcode of failed request: 140 (XVideo)
  Minor opcode of failed request: 14 ()
  Serial number of failed request: 2407
  Current serial number in output stream: 2407

Totem dies with this output:

Gdk-ERROR **: The program 'totem' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 42 error_code 8 request_code 140 minor_code 14)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
aborting...
Trace/breakpoint trap (core dumped)

However, there is no core file in the current directory.

Unfortunately I can not use the ati driver, because it doesn't support my graphics chipset. I could try the vesa driver, but IIRC it doesn't support xv.

[Chris Halse Rogers (raof)]

Thank you for that. It seems that this is actually a problem in xine-lib, so I'll reassign to that package and update the description to match.

While hunting through the backtrace, I've seen that democracy doesn't do enough error checking in its xine bindings. I'll spin that off as a separate bug.

[Reinhard Tartler (siretart)]

does this problem also happen with gxine? can you attach an example file to this bug?

Does this bug also happen with the updated fglrx driver in hardy?

That version has died long ago; no more supported
