I just installed it and videos are playing flawlessly without any syncing problem. One thing I noticed is the audio volume (100%) is not as loud. I played the same video with the default player and the volume is much louder. Is anyone having the same problem?

If you have mplayer installed, uninstall it and then refresh applications in appmanager. It should show you a new version.

AUDIO="-oac mp3lame -lameopts cbr:br=96:vol=8"
VIDEO="-ovc lavc -lavcopts"
VIDOPTS1="vcodec=mpeg4:vbitrate=600:autoaspect:vpa ss=1 -ffourcc DIVX -idx"
VIDOPTS2="vcodec=mpeg4:vbitrate=600:autoaspect -ffourcc DIVX -idx"
SOURCE=$1
nice -n 15 mencoder $SOURCE $RESIZE $AUDIO $VIDEO $VIDOPTS1 $LOG -o /dev/null
nice -n 15 mencoder $SOURCE $RESIZE $AUDIO $VIDEO $VIDOPTS2 $LOG -o "$OUTPUT"

Video encoded this way worked well on OS2007, but the audio is ~0.25 sec delayed on OS2008. Would other settings work better? Any fixes in the works for mplayer? I am using the lastest version, maemo.23.
In this script, shouldn't LOG be set to something?

Mooler:

Here's my problem. Evidently Mplayer is part of the preinstalled software and doesn't show up in appsman installed software, so I can't uninstall, or don't know how, and therefore can't refresh to the new version. If I refresh installed apps, then only map shows up as only update. I'm new at this so bear with me.

Can't find the preinstalled version either when mpalyer is loaded. Clearly, it's loaded, I've used it both audio and video.

Any help would be appreciated. I've exhausted wiki and search and I'm not finding answers, maybe it's me!

Thanks so much!

Have been testing .24 on N800/2008 final with a couple of transcoded files (media converter, N800 hq preset) and wanted to give some feedback.

- This is my preferred video player on the tablet.

- Lipsync works nicely for me.

- When the OS shows a pop-up system message while a movie is playing, e.g. when the battery is low or it needs to signal that it has lost the WLAN connection, this garbles the video for as long as the system message is being displayed (most of the screen goes black, and a small false-coloured still picture of the last video image is shown in the top left corner of the screen). This happens both in full-screen and windowed mode. This is quite distracting. Quick fix: suppress system messages during playback (suboptimal, since you might not notice you're running the battery down) Compromise, if that's even feasible in Maemo: Suppress the original system messages, but replicate them in Mplayer's OSD overlay style (still suboptimal, since inconsistent with standard system behaviour). Best: let system popups overlay regular video output, even if that drops frames.

- When I try to switch from full-screen mplayer to another app via the menu button, this also triggers the same false-coloured ghost image; this even overlays the OS's tasks menu, so that one cannot see adequately which app one is about to switch to. When switching to a browser page including flash elements, the ghost image overlays the flash elements. When switching to GMPlauncher, its window remains blank.

- From a usability perspective, I'd recommend that the launcher and the Mplayer playback window should be unified into one app with one app icon in the left vertical icon bar.

- The app doesn't seem to remember which sound level I set it to for the last video via the OSD. Would be nice if it did.

- In some cases, after a video has ended, the app starts the same video over again untill I kill the process. I wonder why that is - perhaps I am missing something simple...

- In some videos I have transcoded with Media converter from MP4 sources (N800 hq preset 400x240pix, 384Kbit/s for video, 96KBit/s for sound, 2-pass conversion and colour boost boxes ticked), saturated cyan areas show magenta pixel noise that is not visible when I play the file with VLC on my PC.

Apart from these observations, I am already a happy user!

Mplayer is heavily hacked to provide optimal performance. One of those hacks (xsp pixel doubling) means that other apps must not display or things will get garbled. Disabling this hack means mplayer would get something like 4-6 times worse performance so 'let system popups overlay regular video output' is not an option.

One possible change, afaik, would be for mplayer to register its window as 'completely on top of everything' to the X server, so that status messages won't overdraw it. Although, come to think of it, if it hasn't been implemented yet there might be some reason why it can't work.

Serge's Mplayer delivers performance many times faster than a 'standard' media player port. Performance-wise, it is likely the most optimized application ever released for the tablets, and we all owe him huge thanks (if that link doesn't work, here's here's the thread ) for his countless hours of work on it.

You give a good description of issues relating to mplayer - again, most are related to the accelerated playback hacks, and thus are not 'problems to be solved' by mplayer but rather issues related to the underlying OS (issues that will likely be addressed in future tablets). Feel free to stop by the Mplayer project page to leave your comments and feedback.

ArnimS, I am quite aware that this is already an awesome player and I congratulate Serge on the technical achievement. Hacking around system limitations must be a b**** to troubleshoot.

I was just lying on the couch yesterday with my user hat on watching transcoded TED talks with an unstable WLAN connection, and I wondered whether there's a better way of handling the garbled screens.

It'd actually be a major step forward if screen redraw were slide-show-like *while* system windows are being displayed on top (optimised playback at all other times - don't know whether the ITOS actually notifies running apps about the fact that it is about to throw a notification, though). A very minimalist fix would be to just keep a still image of the video while the notification is shown and resume video playback once it has gone away. I still quite like the idea of a hack re-routing notification messages to Mplayer's own OSD code. However, I might just be dreaming

Anyway, great work Serge, it's appreciated.

its been said before, but yes it plays xvid and it really depends on the bitrate of the movie you are trying to play.
