Logitech C525 does not work anymore since????

Post by F4DVK » Mon Nov 27, 2017 7:23 pm

Hello,

Excuse me for my English (google translate),

My LOGITECH C525 camera no longer works with RPIDATV.

I had a version of the beginning of the year, and after updating, it does not work anymore.
When switching to transmission, the indicator lights up and then goes off immediately.
Transmission is not done.

Have you noticed this problem?

Thank you.
Cordially,
Stephane.

Hi Stephane

What software are you using? Evariste's rpidatv, or the Portsdown software?

If Portsdown, please check in the rpidatv/scripts folder for the contents of the prev_installed_version.txt file. This will tell you the last version before your update. And also check the latest_version.txt file for the current version. That will help us with finding the problem.

However, it may not be easy, because the Logitech C525 is not part of the "core" hardware configuration and I do not have one to test with.

Hi Stephane

Some more questions:

Please run the Linux command

Code: Select all

v4l2-ctl --list-devices
and tell me the response (all of it).

Does the C525 have a microphone? If so, please run

Code: Select all

arecord -l
and tell me the response.

Hi Dave,

v4l2-ctl --list-devices:

pi@rpidatv:~ $ v4l2-ctl --list-devices
HD Webcam C525 (usb-3f980000.usb-1.5):
/dev/video0

arecord -l:

pi@rpidatv:~ $ arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: C525 [HD Webcam C525], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0

Thanks,
Stephane.

Hi Stephane

I cannot see why it does not work. Which transmission mode are you using? ANALOGCAM or ANALOGMPEG-2?

If ANALOGMPEG-2, please try it with the audio OFF (Console, System Setup, Audio Input, No Audio, press space bar to select, then enter).

My last idea would be to go back to the "transmitting" script file that worked for you:

Code: Select all

cd /home/pi/rpidatv/scripts
mv a.sh a.sh.201711031
wget https://raw.githubusercontent.com/BritishAmateurTelevisionClub/rpidatv/6f2efd8d94246f9ade005280ac81dc17c10e384f/scripts/a.sh
chmod +x a.sh
cd ~
rpidatv/scripts/menu.sh menu
Then see if it works. If not, you can reverse the change with:

Code: Select all

cd /home/pi/rpidatv/scripts
mv a.sh a.sh.201706301
mv a.sh.201711031 a.sh
cd ~
rpidatv/scripts/menu.sh menu
Without a C525 to test with, that's all I can do unless you have more information about the error messages.

In fact, I used "CAM MPEG2", which worked before with this webcam.
Now it works with "VID H264", but not MPEG2.

I will add an easycap, but how to select one source or the other when both are connected?

thank you,
Stephane.

Hi Stephane

Pleased that you have something working. If you need MPEG-2 you will have to go back to the older script.

It will not be possible to switch between the EasyCap and the C525 without unplugging them (and possibly rebooting). Sorry - there are limits to what is easily achievable.

I'll move this topic to the Portsdown Forum.
