Hi, thank you for such a great project.
I encountered a problem of blurred screen when using jmuxer. I use websocket to transmit the real-time data of the camera to the browser for display, but the bottom half of the image cannot be displayed. There will also be problems when I transfer the h264 file to https://samirkumardas.github.io/jmuxer/h264_player.html.

but it does not appear when I use the client [potplay] that supports h264 file playback.

This problem has been improved when I modified the video head parameter I frame interval to be lower. It seems that jmuxer has some problems with I frame processing.

Hi，Samir Das
This seems to be a problem with the calculation of P frames when there are small fluctuations.

Thank you for the file. Yeah, I also got the same as you described. Will investigate when I get some time.
Don't forget to share if you find the solution meanwhile.
