OpenELEC Testbuilds for RaspberryPi (Kodi 16.0)
Thanks to Milhouse I could get vdr-addon installed. I used http://milhouse.openelec.tv/builds/addons/RPi2/ though to manually install and then updated vdr addons until nothing was left to update.

Some impressions in random order, figuring people googling will find this useful:

- USB on RPi/RPi2 is sadly mediocre only, compared to say an Intel desktop board. I had to ressort to the dwc_otg.fiq_fsm_mask=0xF cmdline.txt hack to get a H264 720p stream at around 10 Mbps working even somewhat reliably. Lots of "FIQ reported NYET. Data may have been lost." before. And even now, every minute or half there is a serious dropout with blocky video and brief pause in audio. 30 minutes into viewing, audio/video is getting pretty skippy to the point where Kodi tries to resample audio, producing squeaky voices.

- Latest vdr-addon Live-TV web interface on port 8008 crashes with segfault on browser connect.

- Quality 2A+ USB power supply is key and even more key is using a thick and short (0.5m) cable from the power supply to the RPi2.

- Snapshot 5.95.3 RPi2 OpenElec does not boot on my RPi2. I have a Hifiberry Digi+ and DS3231 RTC attached, maybe it does not like the new DTBs or those devices.

- If your zd1211rw stick is not recognized (no wlan0 showing up), be aware that new_id was changed in later kernels. The syntax with FFFFFFFF's no longer works. I got mine working using this:

# cat zd1211rw.rules
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0ace", ATTRS{idProduct}=="a215", RUN+="/bin/sh -c 'echo 0ace a215 0 0586 3413 > /sys/bus/usb/drivers/zd1211rw/new_id'"

Coming from Windows with MPC-HC, external Lavfilters (with dtsdecoder.dll) and DVBviewer/vPlug, I may have expected a bit too much of this box. Wink

I'll revisit in a couple of months to check you guys out again. Thanks!

#0726 and #0727 work fine, so the problems started with build #0729c and have continued since, in the same manner. I tried with OMX player checked and it's all the same.

Same problem I reported a couple of days ago. I am on 0727 and that is working fine. Any build higher starting with 0729c and I cannot play mkv files.

And unfortunately I have the same behaviour with #0803 build

What USB tuner are you using?

I have no problems with 8-15Mbs+ 720/50p DVB-S2 satellite streams from a Technisat USB Skystar HD satellite receiver, and have no problems with DVB-T2 August T210 and Pinnacle USB PCTV290e tuners. I've not had to use any config or command line hacks to get them working. TV Headend works pretty well - including CI support. I was able to just about get two 8-13Mbs H264 streams running simultaneously (one viewed, one served to a secondary machine) from the same transponder (and both being decrypted). I've had similar results with multiple DVB-T2 H264 1080i streams - and the deinterlacing support in the recent builds has been pretty good too.

Both AC3 and AAC audio and H264 and MPEG2 video have worked with no major problems

Does enabling omxplayer acceleration fix the problem?
Not RPI specific I'm sure, but between 0802 and 0803 the EPG no longer seems to be updating for live TV. There are no strange errors in the logs either.

Edit: Deleted Epg10.db and rebooted once or twice and now it's working...

I am using a USB Terratec Cinergy H5 (card=79):
Bus 001 Device 013: ID 0ccd:10ad TerraTec Electronic GmbH

It astonished me that Linux would even support such an obscure and long end-of-life Empia
chip. In Windows finding drivers that did not bluescreen during unplug took ages. Oh well
maybe I'll snipe on eBay a compatible stick with a different chipset.

Thanks for taking the time to reply!

As promised debug-enabled builds of the last build - please use if you are experiencing crashes as it will provide a more detailed crashlog (requires FAT partition of at least 384MB).

Nope, back to #0727
(2015-08-04, 11:10)Kiralina Wrote: Nope, back to #0727

Can you provide a sample file that fails to play?
Build #0803 didn't fix the playback problem of x265/HEVC videos when subtitle turned on. Please note that I never had subtitle problem with playback of x264 videos, no matter the subtitle is in .srt, .ass, .pgs, .idx + .sub format, whether it is only English or English and Chinese.
@noggin I dug up a http://www.linuxtv.org/wiki/index.php/Te...k_CT2-4400 online, avoiding eMPIA chipset altogether.

An alternative was a PCTV tripleStick 292e but that one has eMPIA.

Sundtek appear to offer userspace driver support, but it is closed source and I'd like to keep blobs to a minimum. It bugs me already that there is no usable disassembler for start.elf. Also I can forward port a DVB driver to a later kernel's changes myself, but closed source userspace would keep me stuck. No chip porn for Sundtek and chipset unknown.

Chinese sticks with Realtek RTL2832U and Panasonic MN88472 demodulator are limited to QAM128 because the Realtek can't handle QAM256. Driver support also lacking.

It applies to any online content (movies, tv series ) from add ons like istream, genesis, etc. The same content works flawlessly on #0727 . It also applies to all the mkv files I have tried, from my external HDD connected to the router. I have high speed internet (1gb) and an AC class router and the RP2 is wired to the router with less than 1m FTP cable.

Once again, I have no problems with build #0727 and under. Problems have begun with build #0729c and continued with all builds above #0729c.

I have played many mkv files without any issues with the latest builds. To fix the problem I need to be able to reproduce it.

Find an mkv file that is failing. Download mkvtoolnix and run mmg.
That has an option to split a file into multiple chunks. Make a 2 minute sample file from the original. Check the sample fails in the same and upload
(e.g. to dropbox or google drive). If I can reproduce the problem you have I can fix it. Without an example file I'm stuck.

I experienced very similar problem, if not the same, starting after build #0727. In my case it only happened with MMAL player. Activating OMXPlayer solved to eminent problem. Therefore I would expect that MMAL player has a problem affecting all builds after #0727.
