Odroid HC2 + hardware transcoding = green line.

[NormSwarm 13]

Hello,

 

I'm trying to get the HW transcoding to work on my odroid HC2 (it's the same chipset as the XU4).

I'm getting green line everytime I set the HW transcoding with V4L2 (OpenMax doesn't work and fallback to SW).

 

I'm using Amrbian with kernel 5.4.19 and Emby 4.5.0.1 for armhf.

 

Moreover, the HW transcoding is slower than using SW transcoding.

Hi, we're looking into it. At the moment we're just not sure yet.

@@Luke If I can provide anything to help testing it/reproducing it don't hesitate.

I have all the deb of the built kernel to be able to exactly have the same version.

If I downgrade the kernel back into a stable version (4.14.y), Emby Beta 4.5.0 doesn't run, it crashes with a segfault as soon as I access the dashboard.

 

 

Same if I try to run Emby stable 4.4.2.0.

 

The problem also is the kernel 5.6.y isn't stable at the moment, I had to go back to 4.14.y, but by doing so, Emby doesn't work anymore.

[Luke 40096]

What do you mean by the kernel not being stable? Do you know what the issue is?

[NormSwarm 13]

The kernel 5.4.y for the Odroid XU4 is still considered unstable. (cf : https://forum.armbian.com/topic/13742-odroid-hc2-kernel-5430/ & https://dl.armbian.com/_test-reports/2020-04-14_23.51.46.html )

The memory module will crash randomnly when trying to allocate pages.

 

About Emby, on 4.5.0.6 with kernel 4.14.y, emby crash either by doing some memory violation ( http://ix.io/2icL ) at boot or when reaching the dashboard.

 

Or also crash at Boot on on LibraryChangedNotifier:
