Hello, everybody out there!

I have recently installed an Ubuntu 20.04. Of course, I have installed VLC, version 3.0.12. With it installed, I can read DVDs and Blurays without any problem, as well as video files. But I have some trouble while I try to read a stream from my media player. Here is the error message I get on the command line:

Code: Select all

Here is the error message VLC prints in a new window:

When using Totem, I can read the stream, so it seems the problems comes either from my installation of VLC or its configuration. Anyway, I have made this test to make sure the problem does not come from the firewall:

Can anyone help me solve this?

That's a server-side error (HTTP 404). URL does not exist.

Hello, everybody out there!

Thank you for the answer.

That's a server-side error (HTTP 404). URL does not exist.

Well, as I said before, I can read the stream “http://mafreebox.freebox.fr/freeboxtv/playlist.m3u” with Totem. I can also open this stream with my web navigator. I just tried with the Flatpak version of VLC, I can read the stream with it. Obviously, I could not have this behaviour if the stream did not exist.

My guess is the 404 error is unimportant: it is just that VLC is trying to access the URL “https://upload.wikimedia.org/wikipedia/ ... (2008).png” to get the logo of the streamer, and this URL does not exist indeed. But this is not a problem. What I need is to read the stream. So, the relevant error is:

Code: Select all

[00007f5a3d184a90] mjpeg demux error: cannot peek

And this error, I do not know how to solve it. However, as I can read the stream with the Flatpak version, it means it is possible to configure VLC such as it can read the stream.

By the way, I really rather use VLC version from standard repository than the Flatpak version, as for some reason Bluray support is better with the standard version.

Best regards.

Maybe look at the verbose logs like the error message suggest?

Please note that Debian VLC builds do not support RTSP by Debian policy decision. Use the Flatpak if you need RTSP.

Hello, everybody out there!

Sorry for the late response.

Please note that Debian VLC builds do not support RTSP by Debian policy decision. Use the Flatpak if you need RTSP.

Well, that pretty much solves it, as I try to read RTSP streams. So, I should use the Flatpak. I have few non-blocking issues with it, but I will do separate messages to solve them. So this issue is solved, thank you!

Best regards.

Or Snap, but not .deb's.
