Mibox and Kodi playback choppy?

by blusky75

Although I use Nvidia shield, I bought my dad a mibox android tv (to replace an older Intel atom htpc he used to run).

I was hoping the mibox would resolve choppy playback issues with many of his movie rips (xvid / divx 24fps).

Symptom - when a movie is played full screen , some of these Avi files result in choppy playback (15Fps max). When I escape out (i.e. the movie still playing) , it's butter smooth if there are UI elements on the screen (e.g. Kodi home screen with movie playing in the background ), when I drop to full screen again the choppy playback returns.

Very strange. Both the htpc and mibox do this.

Could it be their TV? They have a Sony 1080p LCD (can't remember the model number) and video smoothing is turned off (they hate he soap opera effect that 120hz brings).

Other files (e.g. 1080p h264 MKV rips) play just fine in Kodi on the mibox (no choppy playback)

The mibox display setting are at their default.

I also tried experimenting with the system > video settings to no avail.

Any ideas?

I have a shield TV and a Samsung 1080p LCD and I cannot replicate these issues with my setup (the very same video files play fine)

Use the SPMC App, it has software decode support for older stuff like Xvid & DivX that is mpeg4 encoded.

You could try turning off all video optimization on the TV. Like ‘Reality Creation’, ‘Smooth Gradation’ and ‘Noise Reduction’ . Look for anything to do with fps or refresh rate since your source videos are 24fps.

Then fiddle with those types of settings in Kodi.

But it could very well be that the mi box just doesn't handle xvid/divx through hardware acceleration, instead having to use software decoding. This is fairly common on tablets and phones for them to only accelerate a handful of newer, common formats like h264, hevc but skipping older ones like xvid, MPEG 2.

A quick test, convert a video from xvid to h264/mp4.
