# Video Decode Sample
|
|
This sample illustrates the FFMPEG demuxer to get the individual frames which are then decoded on AMD hardware using VAAPI.
|
|
|
|
This sample supports both YUV420 8-bit and 10-bit streams.
|
|
|
|
This sample uses fork() to create multiple processes to decode the same input video parallely.
|
|
|
