@popcornmix I'm experiencing a strange issue with your latest newclock4 updates, on XBian.

I have a build from 20141004 that is working fine (unfortunately I don't have a backup of the newclock4 patch file). Yesterday I have updated to latest master and latest newclock4, I've also updated the firmware.

From time to time I randomly get a blank screen and no audio when using passthrough. I have tried to:
* disable GPU accelerated resampling (set to High) - this, and the firmware, seem to be the only changes since 20141004;
* disable Adjust PLL (set to any other value), just to be sure;
* both.

A debug log doesn't show anything relevant and anyways no ERROR lines.

When this happens, CEC is still working (indeed I can stop the video, and the GUI is then shown).

If I disable passthrough the issue magically disappears. So far I have only tested with AC3 (2.0, 5.1) videos. My TV also supports DTS so I'll test later.
I know this is usually related to the power supply, but I've measured it a few months ago, and I'm not sure why disabling passthrough would fix it if that's the case.

I'd like to try the older firmware and I'm wondering if it'd be safe to do so (I'll make sure to disable GPU resampling), or it would explode.

Edit: if it's relevant, all acceleration settings are enabled, so I'm using OMXPlayer.

Tried to investigate it further. It seems I only get this with 25 fps videos.

The video still continues even if I don't see anything. *Some times* it recovers itself after a few seconds (rarely minutes), otherwise I have to stop the playback, resume from there and rewind.

I've noticed 25 fps videos were played at 50, so I have tried adding this to advancedsettings.xml:

Code:

<video>
    <adjustrefreshrate>
        <override>
            <fpsmin>24.99</fpsmin>
            <fpsmax>25.01</fpsmax>
            <refresh>25</refresh>
        </override>
    </adjustrefreshrate>
</video>

I *think* (as I said, it's random, so I'm not sure...) the issue is more rare now, but I still get this.

As a test I have also tried config_hdmi_boost up to 7, but it didn't change anything.

Any suggestion on how to further debug this? (As I already said, a debug log when this happens is not different from a debug log when it doesn't.)

Do you get the issue with an OpenELEC build (either latest stable or Milhouse's newclock4 build?)
Do you get the issue when building from master (rather than newclock4)?

Thanks.

I'm building from master and applying newclock4 on top of it.
I'll see if I can try OpenELEC tomorrow.

I'm building from master and applying newclock4 on top of it.

But if you don't apply newclock4 do you have the same problem?

[pootler]

I have tried all the recent builds, and without exception, if I leave omx acceleration ON, ( i.e default) then searching through video is unusable and results in huge audio/video sync issue when returning to play. It works a bit better OFF, but it introduces a lot of stuttering.

Most of the dev focus is currently on dvdplayer as that has has the most changes since Gotham (and that's what my home xbmc setup is configured to use).
I test omxplayer on and off and it seems to behave fine.

Ideally upload a sample file that demonstrates the problem. Explain exactly what you do to trigger it (e.g. wait 10 seconds then seek forwards twice by 30 seconds, now audio is out of sync).
A debug log when doing this will help confirm if my settings are the same and that I'm seeing the same issue as you.

O.K. - I am hopeful I have stuff for you.

I am afraid the data is in two separate places.

here is the link to the ( not wonderful )video sample which shows the a/v problem.

https://www.dropbox.com/s/683bmiysvk8azw...4.mp4?dl=0

There is no special set of actions that create it - it happens whether you FF for ten seconds or two hours.
As you can see in the video , I only FF for a short distance.

here is the link to the debug log that was running during the video sample.

I hope that is the right data.

many thanks popcorn mix

Hi popcornmix,

I'm sure you are very busy, but- did you catch this post from earlier?

thanks

[*]firmware: audio_mixer: Add more support for 24-bit formats. See: [url=http://forum.xbmc.org/showthread.php?tid=206262]

This build may fix white noise bug with 24-bit audio sound cards (e.g. HifiBerry) with GPU accelerated resampling enabled. If you've had this issue please test and report.

[doveman2]

Moved.

@doveman2 - I think a separate thread would be best for this, it's OT for test builds...

Sure, I'll do that.

Strange,

The last two builds have broken my remote control?

It is a Hauppauge which is used in conjunction with the built in IR receiver of my hauppauge DVB tuner.

I can't even FTP/SFTP into openelec to check if the firmware is still there

Anybody else ?

USB IR dongle and SSH/SFTP working fine here...

But if you go back to #1010, it's all working for you again?

Thanks for the reply.

rolled back to latest official build- everything works fine.

Will try your build suggestion.

[pootler]

O.k, not working with any of the latest at the moment. ( fine with official latest)

Works fine by using usb mouse etc.

Might be an add-on causing it- is that possible?

I don't suppose there is anyway of removing /disabling all addons en masse is there?- I have a lot of addons

Thanks for your time

Ok, what's most useful to know is the last test build when it worked.

Just stop xbmc (systemctl stop xbmc) and rename your .xbmc folder to .xbmc.bak then restart xbmc (systemctl start xbmc) - you'll start with a fresh xbmc setup with no additional third-party addons (or movies etc.).
