By the way, a new build of MPlayer was released today. As promised, it contains some video decoding performance improvements for mpeg4 (up to 10% faster at about 1000kbps video files, this effect is smaller for lower bitrates). Also some video decoding artefacts are now gone as a side effect of replacing old buggy idct code. Most of the work for this optimization was done by Mans Rullgard, and some minor improvements were added by me :)

Success!
Added the following in .mplayer/input.conf so I can now adjust the sound delay in video that were unwatchable because of playing audio out of sync. I discovered there are a ton of other keymappings you can do too.

UP audio_delay 0.100
DOWN audio_delay -0.100

Sure you can do that, always refer original mplayer documentation, it can use tons of configuration options :)

But it would be much better if you provided some additional information about such videos because such behavious is not normal for sure. If you have more than one such file (your report implies that), try to find out what was common in all of them. Maybe it is better to get full mplayer log and submit a bugreport at garage trackers with this information. Thanks.

A very useful discovery indeed - I didn't know that mplayer (any version) could do that. And the annoying thing is: such a feature makes an enormous amount of sense. This bit of info will be very useful to me as I use mplayer to play my video collection over HTTP, and it *appears* that the sound sync problems get worse when viewing videos that way.

Initial version of webpage is now created: http://mplayer.garage.maemo.org/

Please check it for spelling/grammar errors. Also if you have any suggestions about what information can be added there, feel free to propose them here. It is a good idea to have some comprehensive information so that anyone can start using MPlayer for watching video easily and avoid encountering any issues :)

You'll probably want to add a bit about Opera integration.

2Nikster: The most easy way to add this information is to checkout 'www' subdirectory from maemo mplayer SVN, add all the necessary information to 'index.html' and submit a patch. Webpage will be updated in no time :) I used nvu to edit webpage, it seems to be quite convenient for this task.

By the way, did you consider trying to make some .deb package which could add opera integration for mplayer so that it would be much easier for end users?

Please bear in mind that I imagine normal users, will no not want a complete switch from built in video player to Mplayer for all video streams (i.e. RealMedia AV uses built in player)

"I would prefer a plain .deb for mplayer only (nonintrusive and guaranteed not to break user's system) and another one for opera and probably file manager integration"

Additional package with a name something like 'mplayer-opera-integration.deb' which has 'mplayer' in its dependencies would be useful for those who really want it.

I would even prefer a separate .deb package for GUI, but expected some silly questions like 'I installed mplayer package but don't see it anywhere in my system', or 'why do I need to install 2 packages just for a single video player?' :) So everything is now bundled in a single package right now.

I also have this issue, where half of my videos - converted with Kottori's Media Converter - are slightly out of sync, the sound being a fraction of a second ahead of the video. It's too bad because the video quality is terrific.

I assume that if you edit the configuration file like that, you have to re-edit it all the time (depending on whether the video is out of sync and by how much). Bit of a hassle; obviously I concur with the suggestion to make it a feature inside MPlayer...
