MPlayer should report whether tearsync is used or not in its log (visible when starting mplayer from x terminal or when pressing 'report' button after some video playback from GUI).

When playing flv videos from the included GUI, they play fine. They're not stretched to fit the screen (which I'm more than OK with. :-).
I did notice I played part of a video, and stopped it, and the GUI is telling me I can resume from 00:00:43. I'm not sure it resumed from that spot (It looks like it is resuming from about 3 seconds in), but it didn't start at the very beginning when I started it.

Yes, it resumes playback with several seconds backstep.

I initially upgraded it to see whether or not I could view the oldcartoon.tv channel that they were talking about in one of the threads here. (It's a thread about watching lots of channels) Initially, I tried with mplayer .26 and I can watch the cartoons, or I can listen to the cartoons, but I can't do both.

Version .27 performs the same, but I figure that it's because the site doesn't have the right resolution for the tablet.

It might be also slow audio or video codec. A more detailed information can be also obtained from mplayer log.

Anything specific you want me to test?

Not really, just report if anything is broken

I was wondering if anybody tried it.

p.s. I just went from full screen to windowed in Canola2 and there's a bunch of artifacting in the top left, where the small version of the image was. Seems like Canola didn't clear the screen, but the video is still playing fine..
(I'd wait till the end, but it's a LONG video. :-)

It is because mplayer writes directly to the framebuffer and can't synchronize properly with xserver, though it tries its best. That's a kind of hack, but it is needed for good performance.

p.p.s. 770, OS2006.

I hope you have WLAN memory corruption bugfix installed.

OK, All I see is this in the report:
[omapfb] Nokia 770 hardware detected
[omapfb] tearsync is disabled

So, I'm assuming I don't have a tearsync compatible kernel.
So...er.. should I? :-) What exactly is tearsync?
(I'll do some googling now, so that is probably a rhetorical question.. :-)

Also, yes, I have the WLAN memory corruption bugfix applied.

Thanx again,

desiv

edit: p.s. Tearsync information, for anyone interested, starts pretty well at this link:

Check the other mplayer thread, fanoush posted anew kernel with tearsync support (which is you'll experience as mplayer video playback without tearing - N800 already has it).

Well, I would say "check the first message in this thread"

Possible regression:

When i select menu-->settings-->there's an audio delay option of 200ms.

Does this exist for everyone or it happens only to me? Please check it out.

If i remember well, something similar was reported some versions earlier and was later fixed.

On my 770 - OS2006, the audio delay option is there, but it's set for 0ms.

It's audio latency compensation.

Earlier we had a problem with incorrect audio delay estimation for videos with single channel audio.

Please check if you have lipsync problems on your videos, that's more important.

On Nokia 770 this audio delay compensation value is hidden in '-ao gst' audio driver, so that it is not visible from outside.

Compensation for what? Digital to analog audio conversion latency? Or maybe for better audio/video syncing due to limited hardware?

I 've tested videos with both stereo and mono audio tracks: No lipsync problems.

But. i guess that happens because of the very low delay. Right? A 200ms delay is hardly noticed under normal playback conditions. Please correct me if i am wrong.

So, is this audio delay compensation built in the driver module? Is it automatically on? Or did you set up the value? Can we see its value in mplayer.conf under some option?

To sum up: No lipsync problems.

Excuse me for the many questions. I would be grateful if you (or anyone else) can answer them. It would help me a lot, in order to provide more accurate reports in the future mplayer testing.

Another quick post regarding a possible regression.

Back at version 25 we can see at the release notes that "Decoding at half resolution is now usable".

I haven't really tried "-lavdopts lowres" options before. So, a few minutes ago, i edited my configuration file to add it, but it didn't work. Mplayer doesn't open videos now.

I used all the lowres variables that can be found at mplayer's documentation with no success. Moreover, i tried a lot of different video files, but in the end nothing played at all.

Finally, i removed the lavdopts option and mplayer behavior went back to normal.

Can someone please confirm the above? Is it a regression or am i simply using wrong syntax?
