Using ffplay to play video and audio

At the same time, I added ffplay, so it can also be used as a local player.

ffplay has implemented a progress bar and time display.
swipe the left side of the screen to control the brightness, swipe the right side of the screen to control the volume.
the progress bar is drawn by SDL2_gfx, the time is drawn by SDL2_ttf.

# copy ffplay to /data/data/com.termux/files/usr/bin
cp example/SDL2/ffplay/ffplay /data/data/com.termux/files/usr/bin
chmod 755 /data/data/com.termux/files/usr/bin/ffplay

# play video
ffplay -i /sdcard/video/test.mp4

# play music whit 1.5x speed
ffplay -af atempo=1.5 -i /sdcard/music/hello.flac

# 2x speed playback
ffplay -af atempo=2.0 -vf setpts=1/2*PTS -i /sdcard/video/test.mp4

# play at any speed: atempo=x setpts=1/x*PTS

# no window title(set title is null)
ffplay -window_title -i /sdcard/video/test.mp4

# full screen
ffplay -fs -i /sdcard/video/test.mp4

Issues

• There are still some problems with ffplay, when playing at playback speed, drag the progress bar, the time is inaccurate, and the video and audio are not synchronized.

• You can also add some external libraries, such as libx264 libx265 fdk-aac etc, to better support ffplay.
