4k video missing codecs

I want to test my 4k monitor.

I've downloaded a 1GB 2D 4k 60fps video from here:
http://bbb3d.renderfarming.net/download.html

When i start video with Gnome Video Player i have a missing codec error about missing of AC-3 (ATSC A/52)Decoder and  H.264 (High Profile) Decoder:

Re: 4k video missing codecs

You probably need to install either the appropriate gstreamer or gst packages - whichever the GNOME Video Player uses.  Do a "pacman -Qi <package>" on it to see which are the optionals.

Re: 4k video missing codecs

Arch's mplayer has faac support so that's probably your best bet to just test if something works.

Great things come in tar.xz packages.

Re: 4k video missing codecs

FAAC? He has been talking about AC-3 (Dolby Digital). Also FAAC is the encoder, the decoder mplayer/vlc deps on is FAAD2. Also, what's better than mpv + system ffmpeg

pacman -Sii a52dec:
...
Required By    : ... gst-plugins-ugly

I am not sure what gstreamer use for h.264 decoding, maybe the libx264 pulled by gst-plugins-ugly?

If you don't want to guess every time you can simply installed all five plugins (gst-libav  gst-plugins-bad  gst-plugins-base  gst-plugins-good  gst-plugins-ugly)

Re: 4k video missing codecs

Maybe mplayer is using hardware acceleration. Try to get gstreamer-vaapi too. It also requires you to have proper backend/driver. What's your gfx card?

EDIT: do you mean it's sluggish or there is screen tearing by "joggles"?

Isn't it always true that: mpv > mplayer > vlc > gstreamer though.
