I have some videos in HEVC x265 format. My usual media players don't support this format. when I go for a quick search I get HandBrake software for converting this kind of format.

Do you have any cool software of any idea for converting or play such video files without lag or fading gray color on picture.

You can use avconv for converting audio/video files

avconv -i your_x265file -qscale 1 -c:v libx264 -c:a copy output_x264file.mp4

Explanation: 

-qscale 1 - range from 1 to 31 where 1 is the best quality
-c:v - codec video convert to x264
-c:a - codec audio copy as is

You can check what encoders are present with avconv -encoders and you can use something different from x264

You have to be prepared it can take a long time according to your hardware

    This answer still (almost) works on Ubuntu 20.04! As there's no `avconv`, you can just substitute it with `ffmpeg` using the exact same options, and it works. Same holds true for `ffmpeg -encoders`. – mbdevpl Nov 17 '21 at 12:27
