i tried use ffmpeg to convert some types video to h265 to save disk space but for some video, successfully converted and the file size smaller, but cannot play。 the result video codec name is "rawvideo",not hevc.
the ffporbe of raw video is

then, i used ffmpeg simple (I'm guessing that this problem is just a stupid mistake of newbie,maybe like not use avi? And the raw video is nsfw, maybe not suitable for release, XD————but if really need it,can also supply)

does i need any config to specify in ffmpeg commands to get the right codec? (btw, does this video bitrate is normally?)
