convert KAZAM video file to a file, playable in windows media player

Question

I have some mp4 video files that are created by KAZAM in Linux. But I need to play those files on Microsoft Windows only by Windows Media Player (for example I can not install VLC media player). Also I can not use any codec. So I think converting propoerties of file (for example format of files) is the only solution. But I do not know which output format is best for video file

• without losing quality
• ability of playing result in Windows Media Player

Also I want to know how I can convert to that format?

Note:

• I prefer to use VLC media player for converting video files, but ffmpeg is also appreciable.
• Also do you know a simple, light software for screen casting and recording sounds from speaker in Linux-Ubuntu 14.04 which it's output is playable directly in Windows Media Player? I can replace KAZAM by this.

Edit:

I tested output by WMP 12 (for windows 7) and also MediaInfo says:

Answer 1

Your KAZAM video features YUV444P pixel format which WMP may not support without extra filters. Using ffmpeg, run

ffmpeg -i in.mp4 -pix_fmt yuv420p -c:a copy -movflags +faststart out.mp4

---

You can also use ffmpeg itself to capture screen and sound on linux. Basic syntax would be

ffmpeg -f v4l2 -i VIDEO -f alsa -i AUDIO -pix_fmt yuv420p -b:a 64k cap.mp4

where VIDEO is the name of the video device. See http://ffmpeg.org/ffmpeg-devices.html#video4linux2_002c-v4l2 for details.

AUDIO is the name of the audio device. See http://ffmpeg.org/ffmpeg-devices.html#alsa

You can also use x11grab to capture from the X-Window system. See http://ffmpeg.org/ffmpeg-devices.html#x11grab
