Using the 1/29 build and I tried the suggestion to use the two devmem commands. When I do that, playing back live TV 1080i60 content results in a blank screen and I see this in the logs over and over:

[ 1863.756964] mxc_sdc_fb fb.27: timeout when waiting for flip irq
[ 1863.773152] imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x08800000
[ 1863.773201] imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000
[ 1863.789629] imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000
[ 1863.789729] imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x08800000

Perhaps those settings for IPU priority don't work on the Cubox I2?

Install the image I gave you freshly. To get the flash parameters updated and see.

Will do this evening! I don't believe the I2 can set the VPU to 352mhz though, if I read the specs correctly.

[smallint]

The VPU@352M is not really important for me, only for testing with some HD+ content and double rate. All free HD channels are working just fine without it even my 1080i60 test samples.

OK, you have an I2 which is an iMX6 DualLite. Then the addresses probably don't work there. Wolfgar extracted the addresses from the reference manual but I must admit that I am not an expert reading that kind of documents. You can download the reference manual from Freescale (IMX6SDLRM.pdf) and check yourself. I don't have an I2 to test with, just an Hummingboard Solo which should exhibit the same behaviour. I can try to check it.

It could be that I'm paying more attention, but menu navigation did seem slower and the IR response seemed to miss some keypresses periodically. Not sure if the menu navigation is related to the move from 16 back to 32pp in uEnv.txt.

You can set bpp back to 16. It works as well but comes with visual penalties if both video and GUI is shown. Actually not too bad but not as nice as with 32 bpp (no transparency but colour keying). At least for slower hardware it is an option.

First of all thanks for the develpment and making our Solidrun devices work much better than "out of the box"!

I am a Linux noob, but can follow directions like a trained monkey.

Do we need to make a clean burn of the image or can we just replace the files in the boot partition?

For my second question I am going off topic (hope you and the admins don't mind):

I'm having the follow problems with the audio:

- passthrough enabled for all types: audio dropouts all of the time on all formats (so bad the indicaors on the AVR go out).
- passthrough enabled exept DTS-HD and DTS-MA: audio works like a charm but no HD formats..
- passthrough disabled: random static noise on all audio formats. reduced it a bit by disabling "sync audio to video" and "sync refresh to display"

For now I have passthrough enabled but without the HD formats, the reason I upgraded from the R-Pi is the HD audio.

Jim, this isn't a support thread. I've got these problems also, but this thread is about development and smooth video playback. Let's focus on this.
Nevertheless you can install the test-version of fritsch, if you extract KERNEL, SYSTEM and the two corresponding .md5 files to \\openelec\update. Then restart the box and OpenELEC updates to the new image.
Now back to topic....

[smallint]

The devmem settings don't work on my Cubox I4 neither. I get a flip irq timeout. So lets wait for wolfgars input ...

[zaphod24]

Thanks for the quick feedback! Guess we see what Wolfgar has to say. In the meantime, the deinterlacing does look nice and quite happy that it works even on my I2.

[fritsch]

Fernetmenta mostly acked the PR smallint did. It can now go in any time! Very nice.

Installing now, sorry for going of topic, I posted to hastley after a hard day and trying to find some distraction online.
I thought the my issue might be related because most of the time the audio goes awall is just before "something big is happening on the screen".

With the latest image, I get the following trying to use the devmem settings:

[ 5370.142896] imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000
[ 5370.392878] imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000
[ 5371.309593] imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000
[ 5371.442908] imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000

The picture pops in and out but definitely isn't watchable. Without those devmem settings, things seem to be working pretty good.

[fritsch]

I am testing completely without the devmem settings at home and it works fine.

The only thing I did not add to the kernel was the 352 Mhz patch. All my HD+ Channels work find with the 25 fps deinterlacer already without that.

[bubi]

Wow! Thanks for your work, this image is a huge step forward.
This was just quick-testing (~2h), but I'm going to post further long term issues - if they occur.
So far on a CuboxTV (quad-core):
- I didn't recognize any HDMI-disconnects
- VPU tweaking three days ago made things severely worse in conjunction with fritsch's 1/29 image (didn't check it with this image, yet). I got permanent (= every 5sec) HDMI disconnects with even a "simple" video. Perhaps the mem address is wrong?
- 1Gbps networking works, but buffering is quite slow on seeking (still have to check that issue)
- 100Mbps networking: buffering slow also
- bitstreaming of TrueHD 5.1 & DTS-HD 7.1 works without HDMI-disconnects

Now to the test streams (meaning Auto+auto deinterlacing settings):
All of mine (except 1920x1080i60, see below) and all of fritsch's test-streams (http://solidrun.maltegrosse.de/~fritsch/) work perfectly except
- if 720p50: showing codec-info triggers many frame skips
- if 1080p50: massive audio async, and slowed down video.

Remaining issues:
- 1920x1080i60, 29.97fps interlaced (no MBAFF!) https://www.sendspace.com/file/h3znta => video slowdown and quick audio async
- (1080p50 still not working)
- frame-skip or -doubling every 41.66sec from 23.976fps content. Any tips on TV/playback settings? Is HDMI-24p 24.000fps or 24000/1001fps?
- some, but very few
