Bug 119869 – mplayer-bin dvb can't detect tuner type

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Ryan Olf 2006-01-21 15:17:45 UTC]

When trying to open a dvb stream, mplayer-bin gives the following error:

mplayer (64 bit), has no problem detecting the tuner type (but has other problems that I'd like to see if mplayer-bin can help me get around):

They seem to be the same version of mplayer, but compiled with different versions of gcc and maybe different USE flags?  My mplayer use flags are:

Update:  still having the same problem with mplayer-bin.  But there's more, which may help explain the problem (though I still can't explain it.)

I tried installing mplayer in a 32bit chroot with exactly the same USE flags... same problem.  So I set up a bootable 32bit system with exactly the same USE flags.  I boot into it, recompile mplayer, and mplayer dvb runs fine.  If I mount that SAME SYSTEM as a chroot (making sure /proc /dev and my home are mounted in the chroot) I get the same "can't detect tuner type" error as in mplayer-bin.  Can anyone explain this?

The kernel dvb drivers are apparently not cross-bit safe.  There's not a whole lot I can do about it, unfortunately.  I don't even have access to any dvb hardware.

slightly old bug, please test w/newer versions and report back if same issue is still present.

thanks, Ryan
