boba23 Wrote:Well, I don't know what TV/Projector you are outputting your material to, but since VDPAU is only used with HD content, 720p and up. I don't want any scaling to take place on XBMC side. I got a 1080p Panasonic display, and hence I output 1080p on a 1080p unscaled or 720p that is scaled by the Panasonic scaler which does an excellent job.

boba

Well, my TV is running pixel 1:1 at 1360x768 and works nicely with XBMC. I don't change resolution so I am relying purely upon XBMC's scaling capabilities (are you really changing output resolution all the time?). My content ranges from low quality SD content to 1080p, with most at 720p which is slightly lower resolution than my TV. I want to make sure high quality upscaling happens whenever possible...

Hello elupus!

I've been testing and with at least 30 tries with svn r19948, I'd not a single crash to desktop, so I guess that, at least for me, the changes on r19937 fixed the problem =)

Thank you so much!

Just one more addition to that.
After the most recent changes, the bug, which cause XBMC to crash during stoping vdpau playback, when vdpau and XrandR enabled, but strictbinding disabled is come back.

Personally I don't care too much, as I use strictbinding, but as we know, Jaunty was shipped with an nvidia driver which not supporting strictbinding. I just wanted to report back on this.

Hello olympia,

I'm testing now with:
<advancedsettings>
......
<videoplayer>
<strictbinding>false</strictbinding>
<vdpau_allow_xrandr>true</vdpau_allow_xrandr>
</videoplayer>
</advancedsettings>

and still everything is ok, but i dont know if i'm using the right settings (or if they can be set in the advancedsettings.xml or just in the guisettings.xml).

what settings do I've to use to reproduce the problem?

thanks for the info!

Hi maksimenko,

Only this in advancedsettings.xml:

<advancedsettings>
......
<videoplayer>
<strictbinding>false</strictbinding>
</videoplayer>
</advancedsettings>

And enable auto-refresh rate on the GUI (video settings/player)


- boba23 - 2009-05-05 16:24

Could you guys try and clear up for me what exactly those settings do? XrandR is for detecting displays, settings resolutions and rotating, is this enabled by default e.g. in Ubuntu Jaunty? And what does "Strict Binding" do?

Confused I couldn't reproduce the crash... here are my guisettings.xml and advancedsettings.xml for videoplayer:

guisettings.xml:

        <sep3></sep3>
        <upscalingalgorithm>7</upscalingalgorithm>

</videoplayer>

advancedsettings.xml:
Code:
<videoplayer>
         <strictbinding>false</strictbinding>
</videoplayer>

I've tested using svn r19949 and nvidia drivers: 180.51, 185.19 and 185.18.08 and playing/stopping/letting h264 vid finish, worked ok.

Here are some relevant parts of my xorg.conf, just for the sake of comparison:

Code:
...
Section "ServerFlags"
    Option         "Xinerama" "0"

Section "Monitor"

    # HorizSync source: edid, VertRefresh source: edid

....

hope it helps finding the problem...

I am really not sure that using this xorg.conf, the changing of refresh rates are even works at you. Are you sure you can use different refresh rates?


- motd2k - 2009-05-05 21:18

What error do you get upon the crash? Do you have a backtrace?


- boba23 - 2009-05-05 22:03

Alright, first I can confirm that after a svn up and recompile vdpau playback seems fixed for me, no crash to desktop.
I got a question though, about the auto adjust refresh rate feature. How can I see from within xbmc what refresh rate is put out over hdmi? My Plasma screen only shows resolution info like 1080p but not the input refresh rate.
So I can't tell right now if adjust refresh rate is working for me or not.

When watching a movie push z on your keyboard. It will tell you the resolution and refreshrate.

Unfortunately there is no dump file generated so all I can provide is the debug log:

with the crash (strictbinding false):

Without crash (strictbinding true):

I thought what you see there is the source resolution and refresh rate. That's indeed what XBMC sends to the display?

Edit: Alright, I didn't check the Info that pressing "Z" gives me. It seems that I always get 1080p@50hz when playing video, no matter if it's 24p or other content. So I guess "Adjust refresh rate" does nothing for me. XBMC simply seems to use the Resolution/Refresh Rate that's set in Appearance settings.
What do I have to adjust to get auto refresh rate working? Here's my xorg.conf:

The source don't has a refresh rate, it has a frame rate.

...and yes, XBMC is at the refresh rate which is shown there, and this is what you should see on the display if it support the given refresh rate.

I am sure my display supports 24p 50 and 60hz. It's a Panasonic 46PZ80. Question is what am I missing, that XBMC only outputs 50hz constantly, and doesn't adjust the refresh rate according to the movie frame rate, as u stated?
