From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[Resolved] After updating through both APT and the Software Store, I can't play mp4 videos with VLC anymore. The screen goes blank for a second or two then the audio starts playing without the video.. (self.linux)

I'm using Debian 12, Ryzen 7 5700X processor, and Radeon HD 5450 graphics card. I have tried uninstalling and reinstalling VLC but it didn't resolve the issue. Here's an excerpt from the VLC's log file:

glconv_vaapi_x11 error: vaDeriveImage: operation failed

main error: video output creation failed

main error: failed to create video output

avcodec info: Using G3DVL VDPAU Driver Shared Library version 1.0 for hardware decoding

How do I resolve this issue?

Check /var/log/dpkg.log to be sure. Most modern systems use dkms to make it automatic, but you can try reinstalling the driver to be sure.

And also reboot if you haven't already done that, to make sure your kernel and driver are the latest and loaded properly.

I have rebooted multiple times. How do I reinstall the driver for my Radeon HD 5450 graphics card?

I used this command to search through the dpkg.log but didn't get any results for radeon or ati:

cat /var/log/dpkg.log | grep -i ati

Replying to my own post here. I tried to reinstall my video driver but the terminal messages I received essentially said that the files were already installed:

Though my issue has been resolved I'll try this and update this post afterwards

Edit:

I reinstalled the video drivers and rebooted twice to be sure but VLC wouldn't play mp4 files unless I changed “Hardware-accelerated decoding” to “VA-API video decoder”.
