I have HCL me u1 android Tablet with following specs.

  • Android 4.0 rooted
  • display : 800x480
  • 1 gb ram
  • 1 GZH single core cortex a8 processor
  • 5.5 GB free space
  • Usb port

this tab is used only for watching movies with Mx Player App. Mx Player can smoothly play x264 (480p AND 720p AND 1080p) on Hw or Hw+ mode,but not on Sw mode.

But for hevc or x265 (480p OR 720p OR 1080p) video it cant play smoothely,The A-V sync is horrible.

I guess processor is too old for x265 format. So I convert x265 to x264 on pc using Handbrake (time 5 to 6 hours) and then I play x264 video on Tablet.

I am wondering If I could use my tablet for x265 to x264 conversion (tablet can be pluged to charging all the day or even more than 1 day,so no problem of power supply).

does anybody know any app to convert x265 video to x264 video on android?

    If the SoC is too old for playback (decode) of the format then certainly it'll perform even worse at converting (decode and re-encode) it. You can't expect it to take a reasonable time to complete on your tablet when it already takes hours on your way more powerful PC. – Andy Yan Sep 19 '17 at 8:40

  • I didn't put it as an answer either. Also, the -1 (not by me BTW) is for something else - app recommendations are explicitly off-topic on Android.SE. – Andy Yan Sep 19 '17 at 9:14
  • If you think people are not grasping the idea, it's up to you to explain it further via edits. – Andy Yan Sep 19 '17 at 9:16

You may do the conversion using the ffmpeg tool:

  1. Download Termux for Android
  2. Install ffmpeg binary by apt-get install ffmpeg
  3. The command to convert x265 to x264:

ffmpeg -i input.mkv -c:a copy -x265-params crf=25 output.mp4
