Hi @cappadocia5050

This seems like an issue with VLC: https://www.raspberrypi.org/forums/viewtopic.php?t=277903 and https://www.raspberrypi.org/forums/viewtopic.php?t=272977

Could you make sure to have the latest VLC installed?

sudo apt update
sudo apt full-upgrade
sudo apt --reinstall install vlc libvlc-dev
sudo pip3 install python-vlc

Then remove the vlc cache

rm -r /home/pi/.cache/vlc
rm -r /home/pi/.config/vlc

Then do a reboot and try again.

i installed last rasbian and update today , i followed your order ,still get the same mistakes,

btw i use this codes on "raspberry pi zero w " and "no usb hard drive"

i got this mistakes

[markszabo]

Hm. Could you open VLC itself and try to play the network stream there? http://www.messoa.com/faq_detail.php

I have a similar problem.
I can use VLC on my raspberry pi3 but using the vlc lib i see this errors.
As workaround (or better solution?) I have now found another way to capture images through ffmpeg changing the protocol to tcp as explained here
Stackoverflow link
Then you should not get any corrupted images (but i did not test this deeply yet...)
e.g. ffmpeg -y -rtsp_transport tcp -i rtsp://username:[email protected]/stream1 -vframes 1 test.png

You can also use test.jpg and you'd get a jpg file.

Hi,

I have exactly the same problem with the main decoder error: Could not convert timestamp when starting python3 capture.py

Is there any workaround for that? Thanks in advance.

[markszabo]

Hi @Shendrach

Have you tried the steps discussed in this thread? Other than those, I don't know about any workaround.
