I see. It was libdvd depended on ffmpeg.
Is the video player still not working after running --fix-broken install?
Have you tried removing and then reinstalling your video player?
I am as confused by this as you are.
Perhaps you can test it with a different aac video to test it to check if it is just This Video that is troublesome?
Is your normal screen resolution 1920 x 1080?
What is the output of
ffmpeg -i input.mp4
Also, have you tried using a different media player, like VLC?
No help there…
Have you tried using a different video player?
zoom please:
I can see it. It makes it look fuzzier. But at least we are moving in the right direction.
I think you were using Totem before trying VLC. I read somewhere at some time that Totem struggles with MP4. There are many different video players available on Linux. Perhaps you could test a few out and see which one works the best?
I have used Xine player and was happy with it. On Zorin Lite, I use Parole.
There is also Mplayer and SMplayer as well as many others.
I understand that it is tedious, but having tested with VLC, please try a few players and see if you can narrow down the best performance.
Also, thank you for providing translations with your posts. 
Lo puedo ver. Lo hace parecer más difuso. Pero al menos nos estamos moviendo en la dirección correcta.
Creo que estabas usando Totem antes de probar VLC. Leí en algún lugar en algún momento que Totem lucha con MP4. Hay muchos reproductores de video diferentes disponibles en Linux. Tal vez usted podría probar algunos y ver cuál funciona mejor?
He utilizado Xine jugador y estaba contento con él. En Zorin Lite, uso Parole.
También hay Mplayer y SMplayer, así como muchos otros.
Entiendo que es tedioso, pero después de haber probado con VLC, pruebe con algunos jugadores y vea si puede reducir el mejor rendimiento.
