Re: Raspberry Pi 4 possible h.265 decoder?

German DVB-T will switch to T2 with 1080p50 H265 in about 6 weeks. I think that's a job which the current RPi will not be able to do. No, that is too much. We have looked at sample streams. They also broadcast 1280x720@50 and 960x540@50. 1280x720@50 doesn't currently play, but it's one of the examp...

Re: Raspberry Pi 4 possible h.265 decoder?

what video player does kodi use for hevc videos? omxplayer? No, omxplayer only handles pure gpu decoders. HEVC is a hybrid using the 4 arm cores with NEON, plus two cores of VPU and 3D QPU hardware. Its API is ffmpeg running on the arm but it offloads transform, intra, mot-comp and deblock to the G...

Re: Help needed to get omxplayer on SUSE aarch64

The aarch64 kernel doesn't currently support some of the firmware APIs (e.g. openmax/mmal) so you can't do this currently.

Re: Raspbian/Kodi completely scambled video only when using

Post your kodi.log to a paste site (e.g. pastebin.com and I'll have a look.

Most likely I suspect the firmware is too old for the kodi build (these are reported in log file).
Output of "vcgencmd version" would provide some of the information.

Re: Raspbian/Kodi completely scambled video only when using

Can you try disabling deinterlace, or setting deinterlace to Bob (x2)?
(Bring up OSD when playing the video and look in video menu)

Also enable debug logging and post a debug log (.kodi/temp/kodi.log)

Re: Interlaced video output

Have a look at command line omxplayer and --nativedeinterlace option. Be aware that is purely an experimental option that will only work in a very limited set of use cases.
Have a read of this thread for some details of the complexities involved.

It cannot possible be a hardware issue as in "the hardware can't physically handle the stream data size" anymore. It is a hardware issue. The Pi can output 8 channels of 48kHz PCM audio.

Anyway, thanks again; 2400x1080 is a lot better then 1920x1080 :) I've had a look as I wasn't aware of where the 2400 came from. Turns out default max_framebuffer is 1920x1200 (if you don't override in config.txt). There is a limit of virtual framebuffer size of double the physical size. But for so...

Re: touchscreen inversion stopped working PIXEL

The multiplication would be:

Code: Select all

⎡ -1  0 1 ⎤⎡x⎤
⎜  0 -1 1 ⎥⎜y⎥
⎣  0  0 1 ⎦⎣1⎦
with x and y normalised to [0,1]

So (0,0) would give (1, 1, 1) which when un-normalised gives (1280, 720)

You can't achieve a translation with a 2x2 matrix. You may want (0,0) to end up at (1280,720) when display is rotated 180 degrees.

Re: Kodi Image problems with some files

At a guess the file is 10-bit H.264 (Hi10p) which can't be decoded by any hardware decoder. (You can check with mediainfo).
You'll need a pretty powerful PC to software decode it.
If you want to play it on the Pi then convert it to 8-bit H.264 (e.g. with handbrake or ffmpeg).
