unity 录制游戏内视频（1）

1，调用的api可以制作任何类型的视频类型（包含快照，and VR视频）

 92             );

 94         picture.Apply();
 95         var bytes = picture.EncodeToPNG();
 96         File.WriteAllBytes(Path + "/" + count.ToString() + ".png", bytes);
 97         count++;
 98         Debug.Log("Fin the work gender texture");
 99 
100         yield return new WaitForSeconds(0.1f);

102     }

106         while (IsRecord)
107         {
108             picture.ReadPixels(
109           new Rect(0, 0, Screen.width, Screen.height), 0, 0
110           );
111 
112             picture.Apply();
113             var bytes = picture.EncodeToPNG();
114             File.WriteAllBytes(Path + "/" + RecordCount.ToString() + ".png", bytes);
115             RecordCount++;
116             Debug.Log("Fin the work CaptureVideo texture "+ RecordCount);
117             yield return new WaitForEndOfFrame();
118         }
119       
120     }
121 
122 }

一个视频的组成可以看成 每秒24 帧的连续图像组成。

后期将调用ffmpeg的库将图片拼接成视频
