Re: HDMI to CSI-2 via TC358743 on kernel 4.1

[..] Sorry, unless someone can - find a contact for the manufacturer and get them to check it (I'm prepared to help them if they make contact) - or fancies doing a reverse engineer on this board around the audio PLL pins. then I think these eBay boards are going to be video only. Awesome, thanks. C...

Re: HDMI to CSI-2 via TC358743 on kernel 4.1

In case someone eyes the H2C-RPI-B01, I also finally got around to solder the 4 wires which were rumoured/expected to provide audio grabbing from the HDMI stream, that still does not work for me. Maybe I have not properly soldered it, or connected incorrectly, but there is also one further report th...

Re: HDMI to CSI-2 via TC358743 on kernel 4.1

Hoi, I can get vision with raspivid but it's cropped and stretched (think a 640x480 crop and then stretched to 1920x1080). [..] That's using firmware mode. I would also try $ mplayer tv:// -tv driver=v4l2:device=/dev/video0:width=1280:height=720:fps=30:outfmt=yuy2 (with a source which offers that re...

The (unsupported) firmware drivers were limited at 1080p25 as they always used RGB 24bpp at a different CSI2 link frequency. All boards support up to 1080p50 as UYVY using the kernel drivers.
Tried with custom mode for the HDMI output of my thinkpad, @50Hz works indeed. Thanks!

Re: HDMI to CSI-2 via TC358743 on kernel 4.1

./yavta -f UYVY --capture -n 3 --encode-to=- -m -T /dev/video0 | ffmpeg -i - -c:v copy -an -f rtp rtp://192.168.1.192:4242 Nice! Seems like real copy indeed. Interestingly, even that has many seconds of latency for me, over gbit ethernet, 0.3ms RTT. For latency, the firmware based approaches are be...

Re: HDMI to CSI-2 via TC358743 on kernel 4.1

I'm trying to achieve a simple task again: I'd like to stream the HDMI stream to a VLC player on the same local subnet. Device is PI0W, HDMI source is 1920x1080, with UYVY to fit into PI0W's CSI. (grabbing one frame works, and saving a raw h264 with yavta also works). My board can only 25Hz at 1920...

Re: HDMI to CSI-2 via TC358743 on kernel 4.1

Most of the Chinese boards I've seen include a silkscreen describing the pinout of the unpopulated header, so combined with the wiring info of | Signal | B101 header | Pi 40 pin header | |----------|:-----------:|:----------------:| | LRCK/WFS | 7 | 19 | | BCK/SCK | 6 | 18 | | DATA/SD | 5 | 20 | | ...

Re: HDMI to CSI-2 via TC358743 on kernel 4.1

It is possible to send the audio via CSI2 on an alternate data type, but not with any of these drivers. Using Google translate on that blog it appears to be using raspivid or the firmware V4L2 stack - both the unsupported options, and no audio. Both do make a monolithic thing that includes the opti...

@6by9 I am working with the B101 HDMI Input board. I am having trouble wading through this forum on how to get audio to work.

Re: How to install 64-bit centos on Raspberry Pi 4B?

How to install 64-bit centos on Raspberry Pi 4B 2G? That should work with aarch64 centos userland, and either kernel from RaspiOS, or from Fedroa32 or Fedora rawhide. These are instructions to run Fedora32 userland with the RaspiOS kernel, these can be modified for centos userland: https://fluxcoil...
