Raspberry Pi VLC Fullscreen with Aspect Ratio problem

[skakabop]

Hello everyone,

We are trying to use aspect ratio with fullscreen but the aspect ratio command does not work when in fullscreen.

This is the command we are using;

Code: Select all

cvlc file.mp4 --aspect-ratio=16:9 -f

Without fullscreen command, aspect ratio works. But when we put fullscreen command, aspect ratio does not work in the fullscreen video. It seems that, this only happens on Raspberry Pi.

Do you have any idea why?

Hi, can you open a ticket on https://trac.videolan.org with the file ?

Hello,

Trac ticket: https://trac.videolan.org/vlc/ticket/22128

I've added the files from drive and added as comment.

[unidan]

Thank you, I might have a fix, I'll try in the evening.

Hello, is there any update regarding this problem?

[unidan]

Hi, I couldn't reproduce the issue unfortunately, I would need more details.

Hello,

Which Raspberry Pi are you testing on? Our model is 2 years old now, maybe this is an hardware issue. It might probably be interchangable for us if this is a hardware issue.

In addition to this, I can provide further details if you need any. Trac ticket have the logs but do you need something extra?

[unidan]

Desktop environment maybe ? You're using latest raspbian ? I'm using raspberry pi 3 model B+.

Below are the command outputs of the several commands.

Is there any significant difference with your setup? We are planning to change the board if we come across any important difference. Maybe you can suggest some different approach.

Thanks for your time!

Hello,

Sorry for bothering you, we are still trying to resolve the issue. If the only difference is Raspberry Pi version we are planning to purchase B+ and test on that. Are there anything suspicious, or you want to comment further?

[unidan]

Hi, unfortunately I can't advise you on this. I would like to reproduce on a device but don't own your variant.

[skakabop]

Hello again,

We've purchased B+ and it works. This is probably a hardware issue on older versions of RaspberryPi.

FYI.

Hello,

We encountered another problem regarding this. When we started the VLC with the command line parameter -f with --aspect-ratio, first we've seen full screen fully stretched video, but after some milliseconds, it's back to video with black bars. We've tried --deinterlace=0 parameter and now it is working. Have you got any comments about this behavior?

We think the core problem lies in the deinterlacer part. Since when we bypass deinterlacing, it works. I'm going attach logs soon.

Any idea about this behavior?

Thanks...

This is the log with deinterlacer (no --deinterlace set)

This is the log without deinterlacer (with --deinterlace=0 flag)

Maybe deinterlacer overrides custom aspect ratio specified from command line and falls back to source aspect ratio? Our best guess is this.

FYI.

Hi
Just updated my raspberry pi 4 B. And now I can't see vlc video in full screen. Do anyone have a solution?
