Bitmap

[Salabda]

Is there any way of getting a Bitmap from the dji decoder in version 4.16.2 Using the MSDK and an M300 RTk

[DJI-William]

You can setYuvDataCallback in DJICodecManager. In each callback return, save the data into bitmap by yourself. You can refer to the DJI decoder demo.

Is that anywhere in the demo? Sorry, maybe I haven't been able to find it.

[DJI-William]

Saving to JPEG or Bitmap is similar things.

Thanks for that, but I don't really know how or where to set up the setYuvDataCallback methods. My application is pretty simple right now, mind checking it up? Where should I add the Yuvmethods?

Now if I tried to add mCodecManager.enabledYuvData(true); the app crashes, is it possible to have a videosurface and collect the yuv data, at the same time, in any MSDK V 4.x?

[DJI-William]

When the YUV data is enabled, the video surface will stop rendering. In other words, you will see a freeze screen.

Noticed. I managed to get the data from a textureview listener and then pass it to a Bitmap. So it's working now. Thanks for the help.
