Alerino Reis Posted August 22, 2019 Posted August 22, 2019 Kodi with KMS/DRM/GBM backend only Tried MPV, but it didn't seem to work . Looks like MPV is not supported http://linux-sunxi.org/Sunxi-Cedrus#Player_Support we're tweaking the sources and scripts to release a new RetrOrangePi version , so hopefully a working tutorial will be available soon 1 Quote
jernej Posted August 22, 2019 Posted August 22, 2019 @Alerino Reis If you're using ffmpeg patches from LibreELEC, then you need only this additional patch to make it compatible with mpv. I tested yesterday and it works for me when running without any window manager running with either of these commands: mpv --vo=gpu --gpu-context=drm --hwdec=auto video.mkv mpv --vo=drm --hwdec=auto video.mkv You can append "-v" parameter to check if mpv really uses HW decoding. 0 Quote
Alerino Reis Posted August 22, 2019 Posted August 22, 2019 Yes, i used some of the LibreElec patches and kwiboo and lrusak ffmpeg forks, i will recheck my sources and test your suggestion. thanks a lot 0 Quote
stulluk Posted February 29, 2020 Posted February 29, 2020 Any update on this topic ? Did anyone managed to run MPV with HW Video acceleration on 5.3+ Kernels from Armbian ? 3 Quote
Dreyk Posted March 28, 2020 Posted March 28, 2020 I am also still interested in manual, which explain how to manage HW accel in MPV or VLC at Armbian... 1 Quote
Alerino Reis Posted April 8, 2020 Posted April 8, 2020 Took some time to resume working on it... At the moment, i'm only able to get Kodi working fine with hw decoding. MPV and VLC are a no-go.

Pol Isidor Posted May 15, 2020 Posted May 15, 2020 Huh..it seams that it is not so simple for everyone to reach this poing to have a HW acceleration on H3. My goal is to reach transcoding from h264 full HD as input stream (satillite stream from enigma2 receivers) and lower down the resolution to SD in h264 with FFmpeg. I compiled myself the ffmpeg with h264 and libfdk-aac. All this working even without HW but from SD to SD. Is there some detail tutorial how can I reach this point? Thx! 1 Quote

jernej Posted July 20, 2020 Posted July 20, 2020 Well, kernel modification is needed for better decoding (less glitches). Probably new *-ctrl.h files contain new fields (not 100% sure) which also need to be filled. There is no any post processing implemented here like scaling. It would be possible to do that via SoC specific peripherals but that wouldn't be universal and thus it's out of scope of this library. Anyway, I'm glad you succeeded. 2 Quote

jernej Posted August 22, 2020 Posted August 22, 2020 BTW, while your approach may work to some degree, note that you don't set bunch of flags for h265. This may work only in very specific cases. Certainly h265 should be worse than before. 0 Quote
AnonymousPi Posted September 12, 2020 Posted September 12, 2020 Hi Jernej, are you able to elaborate on the h265 compile flags that should be set? 0 Quote
jernej Posted September 12, 2020 Posted September 12, 2020 I mean flags in source, not compile flags. Check what has been removed in h265.c and restore it, with new flag or field names. 0 Quote
UniformBuffer Posted September 30, 2020 Posted September 30, 2020 Hi, i'm interested in this topic, but since i use wayland i would like to get it working on mpv (for example). I got vaainfo detecting the library, but when launched using mpv i got green screen and a lot of "failed to destoy surface". I also have noticed that after a some try, i got an error about failed resource allocation (i imagine because it does not free correctly buffers). Someone have managed to get mpv working? For the context, i'm not using Armbian device, but a Pinephone with PostmarketOS (it's the only Allwinner device i have), but i think a lot of people could benefit from get this driver working. 0 Quote
jernej Posted October 10, 2020 Posted October 10, 2020 Sadly noone maintain vaapi layer, so you're mostly on your own there, which means learning a ton of internal details of vaapi, v4l2 request api and supported codecs. On the other hand, ffmpeg fork with v4l2 request api is pretty well maintained. I know this is not ideal, but for example mpv (with one patch) can work with that modified ffmpeg. 0 Quote

Codecs started stabilizing after 5.11. With 5.14 you'll have stable and fully working MPEG2, VP8 and H264. If you need low effort solution, build latest gstreamer 1.20 RC with gst-plugins-bad with one of the latest kernels. With proper pipeline, it works. If you need out of the box solution, use LibreELEC distro. 1 Quote

jernej Posted February 3, 2022 Posted February 3, 2022 13 hours ago, umtkyck said: how can i find armbian kernel 5.14 for orangepi pc? There is no 5.14 kernel available in Armbian, I talked about minimum version. In general, codecs are improved with (almost) every release, so latest version is best. I only see images with kernel 5.13 on download page, which should in theory work. You can build your own Armbian image with kernel 5.15 (edge). 0 Quote
umtkyck Posted February 5, 2022 Posted February 5, 2022 Jernej, what if i want to make backporting the 5.14 codecs to 5.4 release coming with openwrt for orange pi pc. Is that possible, what do i need to take care doing this operation. Just taking the cedrus drivers will not help generally, right? I wanna port the working librelec libraries to latest openwrt stable distro. Umit 0 Quote

umtkyck Posted February 8, 2022 Posted February 8, 2022 @jernej my main approach is backport drivers to kernel 4.19, due to the limitations they dont want to change it. What if i use ubarobov's images , i guess he used 4.20 for the tests. Also bootlin guys also says 4.20 is working for their toolchains. Do you see any risk on that? Can i run hw decode on kernel 4.19? Umit 0 Quote
jernej Posted February 8, 2022 Posted February 8, 2022 Kernel 4.19 was one of the first which has anything of request API framework IIRC. Task of porting mainlined patches there will be even harder. You can use WIP patches from Bootlin and accompanying libs, but then expect that many videos won't work, especially interlaced H264. Also gstreamer or patched ffmpeg won't be compatible with that API. That's even more futile IMO and don't expect any help from me. 0 Quote
umtkyck Posted February 8, 2022 Posted February 8, 2022 Thanks so much, i will try to backport i hope it works. 0 Quote
