对于固定速率的媒体,如固定帧率的视频或固定比特率的音频,可以将时间信息(帧率或比特率)置于文件首部(header),如AVI的hdrl List、MP4的moov box,还有一种相对复杂的方案是将时间信息嵌入媒体流的内部,如MPEG TS和Real video,这种方案可以处理变速率的媒体,亦可有效避免同步过程中的时间漂移。 FFMPEG会为每一个数据...
PyLivestream.get_framerate(vidfn) gives the frames/sec of a video file. PyLivestream.get_resolution(vidfn) gives the resolution (width x height) of video file. Notes Linux requires X11, not Wayland (choose at login). If Wayland is required, consider OBS Studio. x11grab is used for scr...
