movie

问题 I would like with ffmpeg to slow down a movie I am creating using the flag: -filter:v "setpts=2.0*PTS" However the height of my still images is not divisible by 2, so to avoid the error: height not divisible by 2 (1238x833) , I am using the flag: -vf scale="trunc(iw/2)*2:trunc(ih/2)*2" (I also tried -vf scale=1238:-2 ). When I do this the film is generated but it isn't slowed down, like if the -filter:v "setpts=2.0*PTS" wasn't there. Is there something particular to do in order to have both

问题 I am looking for alternatives to the MPMoviePlayerController on the iPhone. As a video player its functionality is very limited. According to the class reference there is no way to get the current play back time or set a new time, for example. It's just play and stop. Are there any middleware solutions out there for iPhone video playback that offer more functionality? CRI has something in development but it has not been released. I haven't been able to find anything else. Thanks. 回答1: Keep in
