Hi,
I am trying to view video files from my security cam but VLC seems unable to play them, any ideas ?
When the camera detects movement, it produces a video file with the extension .265
When googling, I found that in Ubuntu you need to install vlc-plugin-libde265, but I don’t find this in pamac, AUR is activated.
I installed libde265 but that does not help.
Any ideas howto install this VLC plugin, or how to view my security cam footage with something else than VLC ?
At least I can say that the codec is available by default:
$ pamac list --files vlc | grep 265
/usr/lib/vlc/plugins/codec/libx265_plugin.so
So it must be another issue…
Maybe on the terminal you get some hints:
vlc /path/to/filename
When running:
man vlc
You get the manual of vlc. Or
vlc --help
for the help page.
I however mpv is minimalistic viewer. That could view the files.
Another is MPV.
pamac install mpv
/usr/lib/vlc/plugins/codec/libx265_plugin.so
Is present
When I run vlc from the terminal, I get this
vlc /home/marc/A220829_174142_174156.265 ✔

When I drag and drop the video file onto vlc while it has been started in the terminal, I get the same error messages.
Other video formats play normally.
mpv can play them, but in slow motion, and without sound.
Well no info about the file… I guess you need to use this: VLC secrets: Logging and how it helps with bad files (Never done this but can hold some hints)
What kind of codec is used?
pamac install mediainfo
mediainfo /home/marc/A220829_174142_174156.265
My guess is that the security cam just produces a bare video stream without a container and without sound.
Very likely this.
Put it in a container, then try playing it.
ffmpeg -i ~/A220829_174142_174156.265 -c:v copy ~/A220829_174142_174156.mkv
Edit: Also you can increase playback speed with mpv.
Mediainfo only gives the filesize

I'll have a look at the vlc secrets link later.
ffmpeg gives some more info, it looks like there is no audio stream, see next post.
After ffmpeg conversion, vlc plays the mkv first very slow, and then goes to normal speed.
ffmpeg throws a number of errors, and then makes the conversion to .mkv
It looks like there is no audio stream.

What if you add -vsync 2?
-vsync 2 does not make a difference, but I only have 1 or 2 seconds of slow motion, and then the video plays normal, so it is ok
