Greetings, It's very difficult to decide which list this belongs on, sorry for the noise.
Something introduced in 4.4 has triggered a regression of some sort when watching XviD encoded videos in VLC/MPlayer or even the simplified ffplay utility. In 4.3 I watched XviD encoded videos in VLC and they preformed quite well, now since the upgrade, files that previously played well have noticeable audio/video glitches, these include synchronization issues. (Think Jackie Chan..) I'm not sure how to properly track down the cause of these problems, which appear to be reproducible on every system I own. In both VLC and MPlayer I've tried switching video output modules, this includes XVideo+XSHM/XVideo without XSHM/X11 overlay+XSM/X11 overlay without XSHM.. you name it, I've tried it. Regardless of what I try, the audio/video remain glitchy.. I can tolerate the brief visual problems, but the audio synchronization issues are annoying. Could this be a result of the new scheduler or malloc in 4.4? I have tried running vlc at a higher priority, -10/-20.. I think it helps somewhat, but the issue remains visible. The only solution I can find is pausing the video several times throughout the playback. It may not seem absolutely important, but I occasionally like watching media on my workstations. How can I be of further assistance? I'm more then willing to attach a dmesg, but considering I see the issue on all my system, from a variety of vendors, I doubt it would accomplish much of anything. ([i]The majority are AMD Athlon XP and Pentium 4, anything older I own is bound to have rendering issues anyway..[/i]). Even if I've accomplished nothing with this email, I would like hearing if anyone else is experiencing the problem. -Brynet
