Second on Optimization

What the hell is seconds , Just be quick when changing channels , It doesn't matter how much , Add whatever you can , Run again after 、 contrast , Um. 、、、、、、 I can't see it at all , But you just add it ;

		// Frame loss    When the video frames cannot be processed, some frames are discarded to achieve the effect of synchronization 
        ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "framedrop", 5);
        // Set whether to turn on loop filtering : 0 Turn on , High picture quality , High decoding overhead ,48 close , Poor picture quality , Low decoding overhead 
        ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_CODEC, "skip_loop_filter", 0);
        // Solution to playback delay , Set the detection time before playing  1, Achieve the first screen second on effect

        ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "fast", 1);

        ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "mediacodec-auto-rotate", 0);

Introduction to channel change

---

This is interesting , I read a few online Ijkplayer Code for , Since the change is suicide Activity Switch , The effect of running is that every time you change the station, it's dark , And then opened a new world , I still love life , Look below ;

	/**
     *  Change station 
     */
    public void player() {
        TextView.setText(" Playing ：" + url[i]);
        mProgress.setVisibility(View.VISIBLE);
        mVideoView.setVideoPath(url[i]);
        mVideoView.toggleRender();
    }

Article summary

---

Not much thought , I just want to have an article with more than 10000 clicks , Of course not necessarily this one , I don't know if it's my selfishness or my being too good , The articles written are always against everyone's appetite , But I think it's interesting to see a sentence recently , Let's end with it ！

I used to expect others to help me , Then give them double the return , But they often end up disappointed , But recently I've tried to help others , I suddenly found that more and more people are helping me ;
