Default [Q] Certain .mkv file cannot play

Hi,

I download MX player on my Toshiba L4300VM Android TV and stream the movie using MX player from my computer through ES file manager networking feature. Working great so far, but there is one .mkv file I not able to play (but I able to play from my computer), and it cause my TV restart everytime I click on it.
I use mediainfo to compare the 2 working videos and the not-working one, any idea why?

That's the problem. Yes it's an mkv container, but the video is encoded in RealVideo format. Since RV is proprietary, I doubt your device supports hardware playback. Since it's proprietary, I don't think ffmpeg supports it. MX Player is based on ffmpeg, so whatever ffmpeg plays, MX Player can play.

Try playing it on software mode. If that doesn't work, then you'll probably have to reencode the video.
