termux-sdl

这是一个termux sdl插件，为编译运行SDL2和native app程序！

同时我把ffplay也添加了进来，因此它也可以作为一个本地播放器，ffplay目前实现了进度条，时间的显示，滑动屏幕左边控制亮度，右边控制音量，进度条的实现是通过SDL2_gfx进行绘制的，时间的显示是通过SDL2_ttf来绘制的

ffplay目前存在的bug，当以倍速进行播放时，拖动进度条，时间不准确，视频与音频不同步

ffplay播放：

# example/SDL2/ffplay/ffplay 是一个shell命令，并不是真正的二进制文件
cp example/SDL2/ffplay/ffplay /data/data/com.termux/files/usr/bin

# 播放视频
ffplay -i /sdcard/video/test.mp4

# 播放音乐 1.5倍速
ffplay -af atempo=1.5 -i /sdcard/music/hello.flac

# 2倍速度播放
ffplay -af atempo=2.0 -vf setpts=1/2*PTS -i /sdcard/video/test.mp4

# 任意倍速度播放：atempo=x setpts=1/x*PTS
......

如何使用：

解压examples/libs.zip文件，复制SDL库文件到/data/data/com.termux/files/usr/lib

解压examples/heades.zip文件，复制SDL头文件到/data/data/com.termux/files/usr/include

# 进入examples的示例代码下，执行 make run
# 比如...
cd /sdcard/termux-sdl/examples/SDL2/draw2
make run

This is a termux sdl plugin for compiling and running SDL2 and native app programs!

At the same time, I added ffplay, so it can also be used as a local player. ffplay currently implements a progress bar, time display, slide the screen to control the brightness on the left, and the right to control the volume. The progress bar is drawn by SDL2_gfx , The time display is drawn by SDL2_ttf

The current bug of ffplay, when playing at playback speed, drag the progress bar, the time is inaccurate, and the video and audio are not synchronized

ffplay playing:

# example/SDL2/ffplay/ffplay is a shell command, not a real binary file
cp example/SDL2/ffplay/ffplay /data/data/com.termux/files/usr/bin

# 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

How to use:

Extract the examples/libs.zip file and copy the SDL library file to /data/data/com.termux/files/usr/lib

Extract the examples/headers.zip file and copy the SDL header file to /data/data/com.termux/files/usr/include

# Enter the demo code under examples and execute make run
# for example
cd /sdcard/termux-sdl/examples/SDL2/draw2
make run
