I alluded to this earlier and have been trying to debug it, but it's difficult as the info bar extends past the edge of my display.

When skipping or jumping forward/backward in WMV files, there is a brief (2-4 second) period where the framerate very noticeably drops, usually to 10-15FPS. It then recovers fine. This is duplicatable on videos where it occurs. Thing is, it doesn't seem to happen on all WMV videos, just the vast majority of them, and the videos that work fine appear to be decoded the same method by the codec data in the info bar. The info bar itself extends past the edge of my display, so I can't see the CPU usage and definitively say it's a CPU issue-- but I can't imagine it is, since I'm running a C2D at 2.93Ghz.

Anyone else run into this?

Nobody else has this problem with WMV videos?

[Jezz_X]

probably not many people have wmv files
since its a MS closed source format the hacks to get wma audio and workign probably arn't the best anyway

[rodalpho]

Sure, but other linux media players do work. I'll test out mplayer with the opengl switch later tonight to confirm.

[rodalpho]

OK, I tested it out in mplayer with both the gl and gl2 switches. Both work fine; no slowdown when jumping around in the video. Full logs below.

I am having problems with playing wmv-files too. (Sorry for bouncing an old thread btw.)

I cant forward or rewind in a wmv movie. It's really annoying. Now I'm looking for plugins or scripts that will fix this but I can't find anything.

I'm Using XBMC Live 9.04.1 r20654 (Compiled: May 25 2009)

[rodalpho]

The slowdown has been somewhat fixed, or at least I don't notice it anymore. Instead, as you noted, trick play is totally broken. I opened ticket 5089 for it over a year ago. XBMC has been unable to seek through WMV files for at least a year and a half.

There's a partial fix using external FFMPEG libraries detailed in this thread. With this fix, WMV movies with constantly extending durations now seek perfectly, but those that were totally unseekable remain so.

I don't see it being fixed anytime soon as the devs don't use this functionality. If you really need to watch WMV files, XBMC (and it's derivatives plex and boxee) probably aren't the best choice for you.

[motd2k]

I think theres only one genre that uses WMV... /giggle

[johnny2]

I don't see it being fixed anytime soon as the devs don't use this functionality. If you really need to watch WMV files, XBMC (and it's derivatives plex and boxee) probably aren't the best choice for you.

Welcome to open source, where the only bugs fixed are those that directly affect the developers. If its wmv or rmvb, you're fucked. If the developers have no intention of fixing playback of these formats, they should remove all support of them from XBMC so that end users are not given a false hope that playback of said formats will ever work in an acceptable manner in XBMC.

[rodalpho]

It's not 100% broken, some movies do work, so I would appreciate it greatly if support wasn't entirely removed.

Beyond that, well, yep. This is the reality of open source software.

this means I can´t watch porn! .... almost every clip from hdbits is unwatchable in 9.11 !

this means I can´t watch porn! .... almost every clip from hdbits is unwatchable in 9.11 !

oh my and I was just about to try the new release in hope that WMV might have been fixed ... I better stay with the only 3/4 broken old release then...
