WebWhen using FFmpeg the tool, HW-assisted decoding is enabled using through the -hwaccel option, which enables a specific decoder. Each decoder may have specific limitations (for example an H.264 decoder may only support baseline profile). HW-assisted encoding is enabled through the use of a specific encoder (for example h264_nvenc).
