use the log level to see if anything is bombing -loglevel warnings
use stats to watch it encode -stats check your raw source, x265 only handles "yuv420p" | "yuv422p" | "yuv444p” if your video is "yuvj420p" | "yuvj422p" | "yuvj444p" | "nv12" | "nv16" | “nv2 you need to use x264 you have two operations in one filter, i usually break these apart instead of using pipe as the threading is seems asynchronous > -video:f scale=1280:800 -video:f crop=1280:720:0:40 just try a simple conversion, see what’s broken ffmpeg -i test.avi -c:v libx265 -c:a faac test.mp4 Sent from somewhere in … The Twilight Zone > On Mar 4, 2016, at 23:04, 桃源老師 <[email protected]> wrote: > > >> 2016/03/05 3:12 A.M.
