It can be used to make animations and video games.įFPlay is often used as a testing tool in order to verify the FFMPEG output. SDL stands for “ Simple Direct Media Layer”, meaning a cross-platform development library designed to provide low level access (access to the hardware of a computer) to audio, keyboard, mouse, joystick, and graphics hardware. I still have issues with bigger files.As mentioned in the official documentation, FFplay is a very simple and portable media player using the FFmpeg libraries and the SDL library. This command with formmating stream as mp4 actually works with smaller files.

I'm trying to convert stream into mp4 file using ffmpeg ffmpeg -i pipe:0 -c:v libx264 -crf 20 -an -s 800圆00 -q:v 31 output.mp4
