CM4 on CM4IO with Auvidea B102 try 2
These accompany the forum topic CM4 on CM4IO with Auvidea B102 play dead try 2.
Pages with videos are named by original video timestamps, i.e. 210525-1543 is short for 2021-05-25-15:43 and so on.
This section is related to a new sibling of the topic CM4 on CM4IO with Auvidea B102 play dead which I am yet to hopefully create on Raspberry Pi forum.
As in the pictures at:
Fri May 21, 2021 4:52 pm post except not the CM4-eMMC but CM4-lite is what I use now.
So the case is as per these:
210522-1531
210522-1558
210522-1559
(these are from the
rpi-CM4 page of four days ago).
But I'm only trying to get going this hopefully working setup, i.e. all the same, but with CM4-lite instead of the CM4-eMMC.
And so I followed this guide:
TC358743 HDMI to CSI-2 install instructions
My /boot/config.txt, the three last lines:
dtoverlay=dwc2,dr_mode=host dtoverlay=tc358743,4lane=1 dtoverlay=tc358743-audio
The former allows me to attach RPI-keyboard and its mouse, the latter two should get me the video and audio.
Rebooting gets me the /dev/video device:
crw-rw----+ 1 root video 81, 7 May 23 17:56 /dev/video0
I downloaded the EDID file: 1080P50EDID.txt.
And this is what the commands from the guide got me:

But here's a script, because I got tired of running these by hand. I had to run the script quite a few times as well, because I do have issues that I don't know how to deal with:
echo "v4l2-ctl --set-edid=file=Downloads/1080P50EDID.txt" v4l2-ctl --set-edid=file=Downloads/1080P50EDID.txt read NOOP echo "v4l2-ctl --query-dv-timings; sleep 1.5; v4l2-ctl --set-dv-bt-timings query; sleep 1.5" read NOOP v4l2-ctl --query-dv-timings; sleep 1.5 v4l2-ctl --set-dv-bt-timings query; sleep 1.5 echo "v4l2-ctl -V" read NOOP v4l2-ctl -V echo "v4l2-ctl -v pixelformat=UYVY" read NOOP v4l2-ctl -v pixelformat=UYVY v4l2-ctl -V echo "v4l2-ctl --log-status" read NOOP v4l2-ctl --log-status >> v4l2-ctl--log-status_$(date +%y%m%d_%H%M%S)
I saved it as /usr/local/bin/CM4_Auvidea_B102_setup.sh. (Do$ chmod 755 /usr/local/bin/CM4_Auvidea_B102_setup.sh and you can run it on command line, like$ CM4_Auvidea_B102_setup.sh.)
And regarding the audio:
v4l2-ctl --list-ctrls

User Controls
audio_sampling_rate 0x00981980 (int) : min=0 max=768000 step=1 default=0 value=48000 flags=read-only

power_present 0x00a00964 (bitmask): max=0x00000001 default=0x00000000 value=0x00000001 flags=read-only
And now I tried to get the video recorded.
I'm much more familiar with FFmpeg than gstreamer, so here's the command that should have worked:
ffmpeg -f v4l2 -input_format uyvy422 -probesize 12M \ -s 1920x1080 -i /dev/video0 -b:v 256k -f mpegts \ EuroNews_$(date +%y%m%d_%H%M).ts
But instead, it got me just a few frames from the source (pls. download):
EuroNews_210524_1818.ts
You can also view the FFmpeg's log of the try:
EuroNews_210524_1818_ffmpeg.log.
That's just one of many tries.
So I thought, let me try ustreamer.
Here's the command that I constructed to get me less typing for the many tries. I would, say, just change ll=2 to ll=1 to get less logging. This is on my SOHO, which is something equivalent to: 192.168.5.0/24.
The read NOOP is just to give a pause to see how the script fares, it isn't supposed to do anything. I'm also inserting newlines for readability, but I actually run it all on one line.
ll=2; echo log-level set to: $ll; read NOOP;
ts=$(date +%y%m%d_%H%M);
touch ustreamer_${ts}.log ;
ustreamer/ustreamer -m UYVY -n -s 192.168.5.103 \
-r 1920x1080 -t --log-level $ll \
|& tee ustreamer_${ts}.log
The |& tee is redirection to ustreamer_${ts}.log. To see what ts=$(date +%y%m%d_%H%M); does, run it in a terminal.
Once the ustreamer got going, I ran from elsewhere on my SOHO:
ffmpeg -i http://192.168.5.103:8080/stream \ -thread_queue_size 256 -r 50 -f alsa -i hw:0 \ -s 1920x1080 -b:v 2048k \ EuroNews_$(date +%y%m%d_%H%M)_ffmpeg-from-ustreamer.ts \ |& tee EuroNews_$(date +%y%m%d_%H%M)_ffmpeg-from-ustreamer.log
And these got me (pls. download/view):
EuroNews_210524_1809_ffmpeg-from-ustreamer.ts
EuroNews_210524_1809_ffmpeg-from-ustreamer.log
I also post two log-status logs, that show the same now you see me, now you don't differences btwn them:
v4l2-ctl--log-status_210524_180752
v4l2-ctl--log-status_210524_180836
Both have the No video detected line and many other info that I currently have very little if any understanding of.
Have I forgotten any details?
We'll know as I ask for help on Raspberry Pi Forums:
UPDATE 2021-09-24: CM4 on CM4IO with Auvidea B102 try 2 (and try 3) (of which topic I of course did not know the location when I wrote this page).
