 # Video decode memory sample
 
-The video decode memory sample illustrates a way to pass the data chunk-by-chunk sequentially to the FFMPEG demuxer which are then decoded on AMD hardware using rocDecode library.
+The video decode memory sample illustrates a way to pass the data chunk-by-chunk sequentially to the FFMPEG demuxer which is then decoded on AMD hardware using rocDecode library.
 
 The sample provides a user class `FileStreamProvider` derived from the existing `VideoDemuxer::StreamProvider` to read a video file and fill the buffer owned by the demuxer. It then takes frames from this buffer for further parsing and decoding.
