Hi, I've compiled both hyperion and hyperion.ng with AMLogic support for my Vero4K. Both version work (although the "classic" version appears a more stable) fine for h264 files but produce a random "pastel coloured" pattern when playing HEVC content. Is this a known issue? N.
I'd like to let you know I encounter the same issue. With HEVC (x265) content ambilight is working so bad that I can't use it at all. Could you guys look into this and try to find a fix? If testing is needed please let us know!
Not necessarily. This one says 8bit.

Execute this: echo 1 | tee /sys/module/amvdec_h265/parameters/double_write_mode works fine with 4k HEVC HDR media on my Odroid C2, although it cant display 10 bit correctly (washed out colors)
I tried it but get a permission denied both with and without sudo: osmc2:~$ echo 1 | tee /sys/module/amvdec_h265/parameters/double_write_mode tee: /sys/module/amvdec_h265/parameters/double_write_mode: Permission denied 1 osmc@osmc2:~$ sudo echo 1 | tee /sys/module/amvdec_h265/parameters/double_write_mode tee: /sys/module/amvdec_h265/parameters/double_write_mode: Permission denied 1
try echo 1 | sudo tee /sys/module/amvdec_h265/parameters/double_write_mode What OS do you use? I'm on LibreELEC, so I don't need sudo
Thanks, that worked . So should I see a difference now with hyperion and ambilight? In that case I'll do some testing again. I use the Vero4k OS: https://osmc.tv/vero/
Yeah you should see a difference, at least for the Odroid C2 which uses the S905 CPU. On LibreELEC you need to execute this command on every startup, not sure about OSMC
Sorry for the very late reply. I was superbusy and even forgot about your suggestion. Just tried it and.............works! Didn't try a lot of HEVC stuff but at least 1 movie is working. Any idea how I can automate the automatic running after a reboot? Now I still need to fix the colors/saturation/brightness item. That is on the Vera4k I run Hyperion NG and I can't seem to get the colors/saturation/brightness like I had them in Hyperion (on the pi3). I already messages penfold42 who hopefully can help me with that.
Nice!! In LibreELEC theres a autostart.sh file. I dont think that works for omsc, but im sure you can find a way to run that script on startup. Maye crontab
