I recently upgraded mplayer to rc2. I tried to watch a dvd, and for some reason it only works as root. The error I get when attempting to play as myself is the following: All the normal stuff... Then: ========================================================================== AO: [alsa] 48000Hz 2ch s16le (2 bytes per sample) Starting playback... a52: error at resampling a52: CRC check failed! 0.038 ct: 0.000 1/ 1 ??% ??% ??,?% 0 0 a52: error at resampling a52: CRC check failed! a52: error at resampling When I play as root, it all works perfectly. At first, I thought that this problem related to region encoding, but i have set the region of my dvd to the correct region and the fact it works as root I think disproved that theory (as an aside, for the life of me I couldn't find a tool which could tell me what region a dvd in the drive was!!!) Any help would be appreciated!! Oh - and I tried setting the suid bit on /usr/bin/mplayer and it made no difference.

Sorry - I forgot to mention another quirk. It is only track 1 (of 4) of the DVD which has this problem. Output of lsdvd: Disc Title: THE_SHAWSHANK_REDEMPTION_SE_D1 Title: 01, Length: 02:16:26.060 Chapters: 40, Cells: 42, Audio streams: 02, Subpictures: 02 Title: 02, Length: 00:02:06.000 Chapters: 01, Cells: 01, Audio streams: 03, Subpictures: 03 Title: 03, Length: 00:00:12.020 Chapters: 01, Cells: 01, Audio streams: 03, Subpictures: 03 Title: 04, Length: 00:00:47.020 Chapters: 01, Cells: 01, Audio streams: 03, Subpictures: 03 Longest track: 01
So it happens with all DVDs as the summary suggests? Or with one chapter of one DVD as comment #1 suggests? Or... ???
Good question! I've tried a couple of more dvds and they work perfectly fine??? I assumed it wasn't a problem specific to the actual DVD given that I could play it fine logged in as root (and the problem occurred with the first DVD I tried after the mplayer update). However, I can't think of a reason why a physical fault with the DVD would go away when I play the track as root. I've also tried the dvd on a windows box and it works fine. Not sure where this leaves it all! Why would I have to be root to play this specific track on this specific DVD? Is there some way I can give you more info on the dvd itself?
It could be anything. There are lots of reasons for crappily encoded DVDs.
hmmm. Given that the DVD works without fault on a Windows box AND as root, I would more have thought that the bug was with mplayer. It stands to reason that it's just some kind of permissions fault, but I have no idea how to fix it! I've done some more ferreting around, and one bit of information in the output that I noticed was different about the dvd that wasn't working is the following line: (somehow I missed this earlier!!) VIDEO: MPEG1 720x576 (aspect 3) 25.000 fps 9100.0 kbps (1137.5 kbyte/s) In the other DVD that I've tried that worked, the line was: VIDEO: MPEG2 720x576 (aspect 3) 25.000 fps 9800.0 kbps (1225.0 kbyte/s) Is there any reason why the fact that it's MPEG1 encoded make any difference re necessary privileges?
Old bug, please test and reopen if it's a problem with newer ( 1.0_rc2_p20090731 )
