Repository for v4l2request hardware video decoding (rockchip, allwinner)
I don't like my chances of any resolution to this problem but here goes. I'll start off by saying thanks for providing this repository, I recently went on holidays and was able to use my little magcubic box to watch content off my nas remotely. It was mostly great. One issue I have come across is most of my SD content (ripped from DVD) just displays a black screen. I encode it to 10 bit x265 the same as I do for blurays. Blurays at 1080p play fine, the DVD rips at 480p and 576p just display a black screen, audio works. When comparing them with MediaInfo the only real difference (aside from resolution) is the color primaries, transfer characteristics and matrix coefficient tags. Blurays are bt.709 and the DVD rips are bt.601. Also NTSC vs PAL for the blurays. I've also come across some files that I believe I downloaded at some point that are DVD resolutions, 10 bit x265 PAL that play ok. In MediaInfo these files are missing the all the tags mentioned above. I don't know how this is possible... To troubleshoot I've tried converting a non working file to 25 FPS (PAL) and setting the elements above to bt.709 but no dice. I've run mpv from the terminal in verbose mode and tried to compare a working file to non working file and nothing is really standing out. I think ffmpeg is just serving up black frames with v4l2 in certain circumstances, maybe when the color primaries are bt.601. I'm not overly confident the method I used above to set the bt.709 values would actually work. I installed mplayer and this plays the files ok but doesn't have hardware acceleration. This is why I think the issue is ffmpeg and v4l2. Probably not relevant but 2160p content plays (bt.2020). It really struggles with it but it displays an image. Any ideas would be great. At this stage I'm probably going to take a 10 second clip of a non working file and just run it through bunch of different encode settings until I get something that displays and work backwards from there. -

Hello everybody. I'm new to this and I would like to install Linux on my BTV X p212 TV box. I saw that there are several versions of systems but I couldn't find them for this specific one and I would like to know if you can help me? Please. Ps: I searched here on the forum, google but I couldn't find it. -

Orange Pi RV2
Good news: this is merged in Armbian main now, many thanks to @c0rnelius and @Igor for reviewing this. So no more need to grab my fork, just clone Armbian/build:main. I was able to build and quick-test orangepirv2/edge-kernel and this looks fine including Wifi. There are of course unsolved quirks currently. With edge-kernel, Wayland does not work, we need to use Xorg. And with the current bcmdhd Wifi driver, AP mode is not possible. This is caused by outdated file in armbian-firmware for bcmdhd and may be the same on OrangePi5. There is a mechanism to load a different fw_bcm43456c5_ag.bin (the one downloadable from github/xunlong seems to work). LG // Sven-Ola
