Hyperion issue: playback slowdown and halting.

Hi everybody! I'm using LE8 (builds from kszaq, afl1 and johngalt) either on s905 (K1 Plus) and s905x (Coowell V5) devices, and i've faced same playback problem only when hyperion enabled: absolutely randomly video becomes glitchy, slows down and finally hangs for a while (live-tv) or jumps-over a little bit forward (other media). Same time in kodi.log appears "Process - stream stalled" and "WaitForBuffer - timeout waiting for buffer" warnings. One more thing i've noticed - during hyperion's running there is enormous amount of "codec:amvideocap"-related messages floods the kernel's log (see example below). Googling this messages gave me this, so now i believe that my problems are related to kernel.
Please, could someone of our amazing developers help me to overcome this annoying bug? Many thanks in advance!

I will include the amvideocap from Memphiz in my next build. I'm wondering why I forgot it, perhaps nobody need it before.

Remember that amvideocap may not work properly for 4K videos.

Thanks for your efforts, kszaq! But problem still persist with same symptoms

Maybe this bug is related to kernel log spam from amvideocap (check the link in my 1st post).

Yup same issue, using Hyperion from LE repo.

i think it may have to do with the cache size in advancedsettings.xml, particularly readfactor.

I originally had readfactor set to 5 and buffermode set to 0.

now its the below.

<cache>
<buffermode>0</buffermode>
<memorysize>139460608</memorysize>
<readfactor>2</readfactor>
</cache>

its taking much longer for the slowdown to occur, before it was 40 minutes now its 1:10.

EDIT: In the kodi logs i see NOTICE: CVideoPlayerAudio::Process - stream stalled, trying again with buffermode set to 1.

Please, maybe someone of the developers could try to build kernel with changes, mentioned in my first post? I'm not experianced enough for build a kernel by myself, but i can do heavy testing There is no need to rebuild a whole LE on every testing iteration - i need just kernel image, so maybe somebody could spend some time for this? Thanks in advance!

The patch is included in my 8.0.2e build.

Kszaq been running 8.0.2e since release and tried everything but the video still slows down. I read it was related to having both the internal grabber and AML grabber, removing the internal grabber had no effect.

Hi kszaq! Obviously, you missed my report

Also, Memphiz amvideocap doesn't solve the kernel log spam issue.

No, I did not. You asked to include kernel patches, I told you they are already included.

Oh, ok, you're right So, as i reported, those patches (Memphiz's implemetation) didn't solve the problem. May i ask you also try to remove klog messages from amvideocap, as it done in provided example from my first post? Without those corrections systemd-journal process consumes even more CPU's time than hyperiond itself. And i really hope that this is a reason of playback issues, bacause i don't have any other clue...

TIA from all ambient lighting lovers

In case someone of the developers wants to reproduce amvideocap issue by himself: you don't really need any additional hardware for this. Just install Hyperion from LE repo (or via HyperCon), put any config file with "/dev/null" as output (example), and just use device as usual - problem will appear, sooner or later.

I have the same on my odroid C2.

And on my second odroid C2 i installed raybuntu's rb-leia4.3 and no issues so far with hyperion and live tv and other media.

Yes

EDIT:

Tested with latest raybunyu's krypton 15.3 on my odroid C2 and no issues with hyperion after i edited my advanced settings.
