windows 10 cannot play video generated by skvideo.io.vwrite about scikit-video

I got this to work in Windows media player. The key is to output videos with yuv420p pix_fmt. By default, skvideo uses yuv444p, which isn’t supported by many decoders.

You can try other video file extensions, but you should be able to play a h264 mp4 on pretty much any system. You should try ffplay and vlc players since they use the ffmpeg libraries.

Hi Beyondmetris
Thanks for your help. Yes, I tried VLC player and it works for playing skvideo generated videos. and I was able to use VLC to convert the video to a file that can be played by windows media player:

This seems to be workaround for me so far.
Maybe I will need to specify some ffmpeg writing options in order for skvideo.io.write generated file to be directly playable by windows media player. I am checking.

thanks
