Through thisffmpeg-rockchipfork, users can obtain the fastest hardware transcoding and filtering speed on the Rockchip platform via CLI (command line). And the code style has been kept as consistent as possible
-preset ultrafast as the name implies provides for the fastest possible encoding. If some tradeoff between quality and encode speed, go for the speed. This might be needed if you are going to be transcoding multiple streams on one machine. -acodec aac sets the audio codec (internal AAC enco...
