This video is not playing smoothly with totem or VLC under Ubuntu:

http://thomas-guettler.de/tmp/20181011_113036-0.MP4

It works with Windows.

What I mean with "is not playing smoothly" is:

• I see it, but it looks like there are only four frames. The playing jumps.


• On Windows it is smooth. You see the car in the background drive along.

Version: Ubuntu 18.04.1 LTS

Is there a way to get it working like it should???

_{Background: This is just an example. All videos created by my Lumix camera don't play well under Ubuntu :-(}

This is an H.264 30FPS high-resolution video and to play it smoothly you need hardware acceleration, and as it plays smoothly under Windows and not under Ubuntu, (I'm assuming this is on the same machine) this leads me to believe you have installed the correct video drivers under Windows but not under Ubuntu.

So this has nothing to do with Ubuntu or the video itself, but with the video drivers under Ubuntu...

• Go here for nVidia


• Go here for AMD

If it plays well on a fast new Windows machine and doesn't play well on an old clunker that has Ubuntu installed, just transcode the video to a lower resolution and frame rate and the old clunker will be able to play it smoothly as well:

ffmpeg -i 20181011_113036-0.MP4 -c:v libx264 -strict -2 -r 25 -s 1110x832 -c:a libmp3lame -b:a 256K 20181011_113036-1.MP4

_{Note: On my machine running Ubuntu, 20181011_113036-0.MP4 plays smoothly out of the box...}

I can play the video in Firefox and VLC (both installed on Ubuntu 18.04 LTS inside VirtualBox).

So it seems that you have not installed some codecs. Install them with:

sudo apt install ubuntu-restricted-addons

and try again :)

Note: for integrated Intel hardware acceleration is provided by i965-va-driver package; for Nvidia it is provided by libvdpau_nvidia.so library (installed with proprietary driver). You can check status of your VA with vainfo command.

Remarks: on physically installed Ubuntu MATE 16.04.5 LTS the video is played flawlessly only on Haswell i7 (using Intel® HD Graphics 4600). Mobile Ivy Bridge with Intel® HD Graphics 4000 plays video with jumps (in vlc, mplayer, totem, kaffeine, mpv, parole).

If the video is really 4K, then it may be too hard for old graphics :)

18.04 with Gnome Desktop on an old Sandy Bridge processor's Integrated Graphics would be very slow simply moving around windows and resizing them. Try the Unity Desktop instead:

• Install Unity instead of Gnome in 18.04

For even greater speed and possibly stability try Ubuntu 16.04 with Unity Desktop:

On Firefox:- Doesn't simply play. Browser doesn't hang either, it's just shows the video thumbnail. Maybe because of low server speed or maybe Firefox can't handle, not sure.

On MPV with SMPlayer frontend:- Plays smoothly, probably without frame-drop (as it isn't allowed in SMPlayer settings). Though it looks a bit strange on my 720p display. Especially the railings of the gate.

I'm a newcomer in Ubuntu but I've installed these stuff after installing it-

ubuntu-restricted-extras ffmpeg libavfilter-extra i965-va-driver-shaders va-driver-all beignet-opencl-icd

However you probably can't install the beignet-opencl-icd as Open CL isn't officially supported on 2nd generation (Sandybridge) processors.

Hardware decoding is enabled in SMPlayer (video output driver and hardware decoder is set to vaapi, no. of threads for decoding is set to 4)
