* Fix a segmentation fault on some samples when the memory type is 3 (OUT_SURFACE_MEM_NOT_MAPPED) and attempting to save the output (which is not supported)
* update the videoDecodeMultiFiles sample
* update the readme for videoDecodeMultiFiles
* add comments
* use OUT_SURFACE_MEM_NOT_MAPPED instead of integer number 3
[ROCm/rocdecode commit: 31c7c7c104]
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 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.
