# Video decode RGB sample
This sample illustrates the FFMPEG demuxer to get the individual frames which are then decoded using rocDecode API and optionally color-converted using custom HIP kernels on AMD hardware. This sample converts decoded YUV output to one of the RGB or BGR formats(24bit, 32bit, 464bit) in a separate thread allowing to run both VCN hardware and compute engine in parallel.

This sample converts decoded YUV output to one of the RGB or BGR formats(24bit, 32bit, 464bit) in a separate thread allowing it to run both VCN hardware and compute engine in parallel.
This sample uses HIP kernels to showcase the color conversion. Whenever a frame is ready after decoding, the `ColorSpaceConversionThread` is notified and can be used for post-processing.
