RE: OpenELEC Testbuilds for RaspberryPi Part 2 - allan87 - 2013-11-25

Does it occur with passthrough/non-passthrough? - Passthrough
While playing normally or during pause/seeking? - playing
What make/model of receiver/TV? - Samsung HDTV, C7000 series
Does the receiver indicate any sync loss when the chirp happens? - Not aware of such an indicator
Does it occur with all files? - Don't think so. See additional detail below.
Does reverting to an earlier firmware (start_x.elf/fixup_x.dat) solve the problem? - will have to test. will try later.
Can you identify the firmware version that introduced the problem. - The first time I noticed it was after I installed the November 20 nightly build from xbmcnightlybuilds.

Anything in common with files that chirp? (i.e. sampling rate, coded, number of channels) - One file I noticed the effect on was an MP4 with 2 channel AAC audio. The other occasion I noticed it was streaming the Doctor Who 50th anniversary show from the BBC. 2 channels also. No idea what the encoding was. I did not notice the issue in 2 multichannel Mpeg2s recorded OTA and played back with the myth plugin. I can try other files if it will help.

Code:
30.000 40.000 0
may skip from 30-40 seconds of any video file.....

Yes, that seems to work, and actually jumped from about 20s to 40s I believe, so I've got something to debug.

I've added this commit to newclock3 branch (https://github.com/popcornmix/xbmc/commit/d4fc5db82358ad50a159b5bdc2169f6f254f12f7)
that makes my EDL test file skip at the right start point.

No, /var/log/messages has been replaced by journalctl with the change to systemd in OpenELEC 4.0.

Ah, thanks. Wrong assumption on my part.

Need to go and read up on journalctl now, and hopefully armed with that knowledge I'll be able to diagnose my LIRC issue.

this not working getting
grep: /var/log/messages: No such file or directory

With Gotham you need to run:
Code:
journalctl --no-pager --unit xbmc-autostart


Thank yo MIlehouse your build working perfect now ! First i geting an black screen but after changing an option in video settings now i can enjoy live tv !

Also i need to delete the addon15.db to install addons from repos .
Thank you for your amazing build !

Can you explain exatly which option causes the blank screen?


RE: OpenELEC Testbuilds for RaspberryPi Part 2 - ranem123 - 2013-11-25

Popcornmix the options was enable fixed latency playback mode and Frame Multi Threaded Decoding

I had the same Problem with all video files.

I don't believe "Frame Multi Threaded Decoding" has any effect on the Pi - are you sure that was relevant?

Do you get black screen with "fixed latency playback mode" enabled or disabled?

Sorry, now i switch on/off it has no effect.

Hi guys. Is there a repo up that can be setup to run with the awesome openelec-dev-update add on? Would love to be able to roll updates through that if possible. Makes it easier to follow as things progress than looking for dropbox links in this thread. Thanks for all the great work!


RE: OpenELEC Testbuilds for RaspberryPi Part 2 - swetoast - 2013-11-26

well it would be pretty simple of someone with a server setup a test repo and synced it with dropbox so the devs could just add it builds whenever they publish this way the devs gets to keep using dropbox while the rest get a repo they can turn their addons to but again whos willing to host that is the question Smile a simple apache server spinning with the dropbox application is all that is needed Smile

Here's a 100MB sample mkv on dropbox, it's the opening titles from Blade Runner Directors Cut, 1080p/DD5.1. Audio starts at 13 seconds, however chirping is usually evident as the green tree is being traced line by line.

A second 100MB sample mkv (dropbox) - the opening titles from Blade Runner Final Cut, 5 audio streams: default TrueHD, DD5.1 and 3x DD2.0 - is even worse, though I'm not sure if the multitude of audio streams (including TrueHD) is a complicating issue. If you play it then cycle to the DD5.1 audio, stop it and restart playback with the DD5.1 audio, you should hear chirping from the outset.

Note that the chirping isn't continuous, but it is frequent, and sound quality is much worse as a result. I'd say many films are now unwatchable (or maybe that should be "unlistenable").

Let me know if/when you download these samples so that I can delete them! Smile

Going back through my builds, the problem starts with the following build:
Code:
-rw-rw-r-- 1 neil neil 106260480 Nov 20 03:14 OpenELEC.tv/target/OpenELEC_Gotham-RPi.arm-devel-20131120031424-r16398.tar

The build log is here: pastebin - it's not very large, so may not be complete (if a build fails and is restarted to completion, I'm only keeping the log for the successful part of the build). There is a new bcm2385 firmware in this build, but not sure if it is the only change. It's also possible I did a mkpkg_bcm2835-driver of the next firmware to create this build so take any hashes in the log with a pinch of salt. Lucky if I can remember what I had yesterday for lunch let alone what went into this build... Smile

The build prior (created Nov 20 02:51:51) is fine, playing both samples without a problem.
