morning @Ray i see the 7th may image is still suffering with the live tv dvb-t2 slowdown issue (not rebooted box recently so havent checked latest nightly yet), is there any movement on a resolution for this, other than to disable deinterlace (assuming thats what the line below does). The command below does ‘fix’ the issue, im just not sure if this is THE solution or simply a workaround for now?, one thing i can say is that it does fix the slowdown issue when watching hd live tv.
If it is a workaround only then im happy to do some debug for you if it helps identify a better solution.

echo 1 > /sys/module/di/parameters/bypass_all

Use the bypass_all. It also looks better than using Deinterlace. Other than that debug logs are not helping right now.

1342

What video? What codec? h264 or h265?
For h265 there is a parameter to set to get hyperion.ng working properly:

I do own only a 1080p TV so I can’t test it.

1343

Ok cool, thanks Ray, can I assume then that the bypass_all hack will make it into a nightly release or do I need to keep that in the autostart.sh for the foreseeable?

1344

No it won’t because it is personal taste. I do not care about interlaced video. Imo it is something useless from the past. Everyone can decide for themselves what looks better.

1345

i understand what you are saying about personal taste, but for hd live tv it is broken without this fix, so its a bit more than personal taste in regards to deinterlace capability, at least this is true for people who need hd live tv, i accept that is probably a minority of the user base.

in any case, im happy with the workaround, and appreciate the reply ray, i shall carry on with the entry in my autostart.sh :slight_smile:

Nothing more right is possible than bypass_all. Imo Deinterlace is just shit and bypass_all looks better but that’s my personal taste :wink:

It does depend on the type of stream. I use it daily with HD Live TV streams and have no issues.

1348

ahh right!, for reference im viewing HD Live TV via Freeview DVB-T2 in the UK

1349

I have the same issue with hyperion.ng. It happens for h264 videos with 1080p resolution.

1350

You may use the bypass_all parameter? Hyperion is not working with this parameter != 0.

1351

I have just set bypass_all to 1 but still have the issue with hyperion.ng.

Hello Portisch,

thank you for your answer an effort. I’ve this problem with all videos >=1080p in my movie collection.

I’ve downloaded some trailers (hd-trailers) to test, and i have also the issue. The same clip in 720p work, in 1080p not.

Here a example with Avengers:

720p:

720p%20final
720p%20final1702×1104 306 KB

dmesg%20720p
dmesg%20720p1796×827 57.1 KB

1080p:

1080p%20final
1080p%20final1957×1121 381 KB

dmesg%201080p
dmesg%201080p2131×1168 151 KB

->1080p partially the left side is working

Btw: I’ve a clean Coreeelc Version (testing), changed only the language and install from Coreeelc Repo the Hyperion.ng addon (9.1.100.3).

Changing “bypass_all” to 1 isn’t also working here.

Thanks & regards

Changing bypass_all to 1 is just the opposite of what Portisch said.

Hmm, ok i misunderstood something. :flushed:
But it was worth a try…

1355

Same here. Just could not reproduce why the colors dont match. I was watching 1080i where the colors did not fit on middle and right side.

1356

ic, looks like I need to read up on how the firmware/bootloader works here then

1357

Did someone have an idea why Ubuntu doesn’t boot on sd card with Coreelec on EMMC?
There is a boot.ini present.
I have the Coreelec boot logo on screen and it does nothing?
If I put another testing Corelec it boot well on the sdcard version.
I tried to compare boot.ini but not enough familiar yet.

@drdemin @DaM please set enable_switch_fense to 1

echo 1 > /sys/module/amvdec_h264/parameters/enable_switch_fense

Hello Ray,

thank you. Unfortunately it does not work.

Now the playback stutters on 720p & 1080p and also the ambilight stopped working.

Regards
