H264 sei_rotation 竖屏播放支持

[zhangyutv]

ijk是否支持根据sei_rotation 来确定渲染画面的方向

[Android4MediaPlayer]

支持的 用textureview做渲染就好了

[zhangyutv]

videoview 是不能支持旋转？我看C代码里面有处理旋转角度的。最终的原理是通知外层设置方向，而不是渲染的时候旋转？

[zhangyutv]

ffmpeg 能不能支持输出旋转之后的视频帧？

[Android4MediaPlayer]

可以，用filter功能

[bbcallen]

Yes, for ffmpeg. No, for ijkplayer with SurfaceView.

[Android4MediaPlayer]

只支持软解

[zhangyutv]

我看到源代码里定义了下面这个，是不是说目前是disable掉avfilter的？

define CONFIG_AVFILTER 0

[bbcallen]

Yes, it only works with avcodec. Not valuable enough for ijkplayer.

[zhangyutv]

But if I set CONFIG_AVFILTER to 1, I get compile error in iOS.

[bbcallen]

You need also modify config/module-lite.sh

[zhangyutv]

In config/module-lite.sh, I can see that "--enable-avcodec". And I also try to enable ffmpeg options. And I have re-compile the ffmpeg according the guidelines from the README. But still I get "libavfilter/avcodec.h not found" error.

[bbcallen]

--enable-avfilter

[zhangyutv]

--enable-avfilter is already there.

[bbcallen]

Can you show your full build steps and logs?

[zhangyutv]

when I run ./compile-ffmpeg all, I can see the config as below in which you can check that the avf ilter is already enabled.

But when I change "#define CONFIG_AVFILTER 0" to "#define CONFIG_AVFILTER 1" and build the IJKDemo using xcode, I got the previous error which says "libavfilter/avcodec.h not found"

[zhangyutv]

In ijkplayer/ff_ffplay.c, line 56, after I change libavfilter/avcodec.h to libavcodec/avcodec.h, I build it success. From the build log, I suppose that the avcodec.h is install into libavcodec not libavfilter. Is it a bug?

[bbcallen]

Yes, seems like a bug. Fixed on master. Thanks
