Disable "match original framerate" in settings. It does not work with 
Android TVs and does not seem to be necessary with Android TVs.

The video formats supported are dependent on the TV decoder 
implementation. leanfront does not use software decoding for video. 
Audio plays with either the TV decoder or with software decoding.

VC1: Likely not supported by the TV decoder.

H265: It looks like the TV decoder is under-powered.

H254: Likely the file is formatted in a way that is not supported. In 
particular, AVI files are not supported. You can quickly and easily 
convert files that are in an unsupported format to mkv using mkvmerge.

Please open an issue in github for the feature request.
