FFmpegFrameRecorder encoding problem frame

[openmotion]

Hello
what is the format to encode a frame
i use the otaliastudios camera preview plugin for android
i get the frame in the addFrameProcessor function
the format of the frame is : 17

i get the bitmapbytes : final byte[] mdata = frame.getData();

and i put it directly the buffer
((ByteBuffer)yuvImage.image[0].position(0)).put(mdata);

but the video is black

i set the recorder with this parameters
recorder.setFormat("mp4");
recorder.setVideoCodecName("libopenh264");

i tried also to change
recorder.setPixelFormat();

thanks for your help

Maybe this class can help?

if i get byte array directly from frame
final byte[] bitmapbytes = frame.getData();

and push
((ByteBuffer)yuvImage_javacv.image[0].position(0)).put(bitmapbytes);
recorder.record(yuvImage_javacv,getFormatPreview);

where getFormatPreview = 17 (ImageFormat.NV21)

i have this result

according to this documentation
https://natario1.github.io/CameraView/docs/frame-processing

The default is ImageFormat.YUV_420_888.
and the frame of javacv is set to
org.bytedeco.javacv.Frame.DEPTH_UBYTE
( yuvImage_javacv = new org.bytedeco.javacv.Frame(getWidthPreview, getHeightPreview, org.bytedeco.javacv.Frame.DEPTH_UBYTE, 2); )

if i must use this class : http://bytedeco.org/javacv/apidocs/org/bytedeco/javacv/AndroidFrameConverter.html
can you provide an example ?

thanks

也许这个课程可以帮忙？http://bytedeco.org/javacv/apidocs/org/bytedeco/javacv/AndroidFrameConverter.html

如果我直接从帧中获取字节数组 final byte[] bitmapbytes = frame.getData();

并推送 ((ByteBuffer)yuvImage_javacv.image[0].position(0)).put(bitmapbytes); recorder.record(yuvImage_javacv,getFormatPreview);

其中 getFormatPreview = 17 (ImageFormat.NV21)

我有这个结果

根据此文档 https://natario1.github.io/CameraView/docs/frame-processing

默认是ImageFormat.YUV_420_888。 并且javacv的frame设置为 org.bytedeco.javacv.Frame.DEPTH_UBYTE ( yuvImage_javacv = new org.bytedeco.javacv.Frame(getWidthPreview, getHeightPreview, org.bytedeco.javacv.Frame.DEPTH_UBYTE, 2); )

如果我必须使用这个类：http://bytedeco.org/javacv/apidocs/org/bytedeco/javacv/AndroidFrameConverter.html 你能提供一个例子吗？

谢谢

My situation is similar to yours, it seems to be due to compatibility issues with the front-end decoder. But I don't quite understand how FFmpeg.grabAVPacket is converted into H264 stream and Frame is converted into H264 stream. What's the difference?
