Decoded byetbuffer to bitmap

[sam21abc]

I tried to get bitmap

val byteBuffer: ByteBuffer? = decoder.getInputBuffer(inIndex)

                val imageBytes = ByteArray(byteBuffer!!.remaining())
                byteBuffer!!.get(imageBytes)
                val bmp = BitmapFactory.decodeByteArray(
                    imageBytes,
                    0,
                    imageBytes.size
                )

or

bytes = ByteArray(byteBuffer.remaining())

                byteBuffer[bytes, 0, bytes.size]

                byteBuffer.clear()
                bytes = ByteArray(byteBuffer.capacity())
               byteBuffer[bytes, 0, bytes.size]

                val bmp: Bitmap = BitmapFactory.decodeByteArray(bytes, 0, bytes.size)

but every time bitmap returns null. is there any way to get bitmap.

BitmapFactory creates Bitmap from byte arrays already containing bitmap RGB data. Buffers are in YUV format. The easiest way to create Bitmap is to use PixelCopy API. See how it is done at https://github.com/alexeyvasilyev/rtsp-client-android/blob/43a6b20de60683edc83aade76c2a89c8e3464088/app/src/main/java/com/alexvas/rtsp/demo/live/LiveFragment.kt#L80

I want generate bitmap/image from raw(h264/h265) frames. without using surface.
