Question

我正在尝试使用Camera的onPreviewFrame回调来学习编码mp4或任何类型的视频文件。

目前，我正在尝试此帖子中的示例代码

Encoding H.264 from camera with Android MediaCodec

不幸的是，我一直在

上遇到IllegalException

mediaCodec.configure（mediaFormat，null，null，MediaCodec.CONFIGURE_FLAG_ENCODE）;

来自另一篇文章 IllegalStateException when MediaCodec.configure Android，我注意到我必须为MediaCodec设置一些强制值。

我尝试了所有强制性mediacodec的强制性值，但仍然没有幸运的过去

IllegalException。

现在我有点想要尝试的想法。任何建议，意见或提示将不胜感激。

感谢

Answer 1

E/ACodec﹕ [OMX.qcom.video.encoder.avc] does not support color format 19

看起来您正在尝试在Qualcomm设备上使用颜色格式19（COLOR_FormatYUV420Planar，a / k / a I420）。对我的一个设备进行快速测试表明他们的编解码器需要颜色格式21（COLOR_FormatYUV420SemiPlanar，a / k / a NV12）。

EncodeDecodeTest sources中的缓冲区到缓冲区测试显示如何查询MediaCodecInfo以获取适当的颜色格式。由于您正在接收来自摄像头的输入，因此您需要将预览格式设置为半平面布局（NV21），然后在将其传递给MediaCodec之前执行U/V swap。

如果您使用的是Android 4.3或更高版本，则可以跳过所有格式体操并使用Surface预览输出。有关示例，请参阅CameraToMpegTest sources。
