Do you think it is possible for you to make a patch for raspberry to boost center channel on downmix 5.1->2.0. for today rpi behaves differently (i think) than linux build and center channel is "quiter" on raspberry than on linux.

I'm pretty sure the mixing is identical on Pi and other linux platforms. We use the mixing matrices from ffmpeg.
You'll need evidence to convince me we are behaving differently.

It is something that's possible to artifically boost and is on my list of things to do.

I do not know how i can make evidence for you, i have tested it on several movies on xbmcbuntu nightly from 2014.08.08 and #807b build from this thread.
and levels of center channel in 2.0 configuration is definetly diffrent maybe i'm not an audiofile but this configuration is useless for me for wathing files with multichannel audio.

Maybe you can point me where can i find downmix matrix, in which file is it now i can try to change it and compile for myself.

[popcornmix]

You could get evidence by finding a channel test file (you get these that cycle a tone or noise burst on each channel) and use a sound level meter (you can get these as Android or iPhone apps).
Play it with xbmc on linux box and xbmc on raspberry pi and report the levels measured.

Also, on the Pi, try playing with omxplayer and dvdplayer. They should use the same matrices but have very different code paths, so it would be interesting if you think omxplayer and dvdplayer behave differently.

Make sure all the audio settings are the same with each test (e.g. voilume on full, amplification on zero, passthrough disabled, number of channels set to 2.0, normalize levels on downmix enabled, stereo upmix disabled).

Got some logs for you. Hopefully these help. I did notice right away that CleanDatabase failed on #0805

Let me know if you need anything else.

Yep, from #0805:

So it looks like the clean is failing while deleting the tvshow.

The description for the error code is:

Error Code: 1442. Can't update table 'tvshowlinkpath' in stored function/trigger because it is already used by statement which invoked this stored function/trigger.

Doesn't look like an easy fix, and another nail in the MySQL coffin.

Experimental newclock4 build uploaded: #0809c

Same as build #0809b, but with newclock4 patches in place of newclock3. See here for details.

newclock4 additions since previous build #0807b:

• [omxrenderer] Use mmal stereo regions
  
• [omxcodec] Correctly use width/height and crop.width/crop.height
  

[SenorLoco]

Doesn't look like an easy fix, and another nail in the MySQL coffin.

Yikes...that doesn't sounds good. I hope that's not the case. Are there any other good ways to share library/watched status between multiple devices?

[Milhouse]

Yikes...that doesn't sounds good. I hope that's not the case. Are there any other good ways to share library/watched status between multiple devices?

It looks like a fix should be possible, by iterating over the items to be removed (as is already done for movies and episodes and in fact pretty much all of the other tables, but for some reason not for tvshows and tvshowlinkpath), so MySQL may have just dodged another bullet.

Trakt.tv is the other way to share watched statuses, although I've never used it myself. From a quick read, I think Trakt.tv is designed to work best with local libraries, so you'll be back to scanning for updates on each of your clients, although the clients should have synced watched statuses as long as they all have the same media metadata etc. Personally, I'd stick with MySQL as long as you can...

[Huuh]

Will the newclock4 patches in the future allow vdpau sharpness to be adjusted, like it can be with newclock3?

I'd not seen much evidence of sharpness being used.
Any other users setting sharpness to a non-default value?
Out of interest what sharpness setting do you prefer?

I left it at around .07. It was a pretty subtle difference, so if it's hard to reimplement, it's no big loss.

Good to hear. I wasn't looking forward to finding a new solution. Thanks again!

Based on tip of OpenELEC master (f49048a, changelog) and tip of XBMC master (08cc0a7, changelog) with the following modifications:

Build Highlights:

1. newclock3-based build.
   
2. Browsing into archives (zip, rar etc.) is now disabled by default as this is often very slow and can also lead to out-of-memory situations. Can be re-enabled in Settings -> Appearance -> File lists -> Support browsing into archives. How many users are using archives?
   
3. When commencing playback, a 1280x720 black jpg is loaded into GPU memory, the purpose of which is relevant only when video is being played in the background (window mode). Not loading this texture saves about 100ms at video startup, and reduces GPU memory usage by 4MB. The only downside is that the skin background is visible while video is in the background, when before it would have been blacked out. This change affects only Confluence. How many users are watching videos in background mode?
   

Build Details:

1. OpenELEC:
   • repository.unofficial.addon.pro: show project/arch

   • [android] Add 5.1 PCM playback support (PR:5082, 1 commit, 5 files changed)

3. newclock3:
   • filesystem: Make support of browsing into archives optional
     
   • confluence: Remove media-overlay.jpg for when video is backgrounded
     

[slack3r]

Have you problems with newclock4 and subtitles? Try skip backward/forward during playback.

Thanks

Have you problems with newclock4 and subtitles? Try skip backward/forward during playback.

Same with newclock3. Sometimes subs do not work. Skip Forward fixes it most of the time.

Lately my TV turns itself on even though I turned this behaviour off in the CEC-Settings.
This happens mostly when I am not at home or at night, so it's a little difficult to provide a debug-log.

Can you narrow down a build when this started happening, does it happen with stock 4.0.7?
