制作可流式传输/可定位的视频

The expected results should be that the video can be streamed at 127.0.0.1:8080 with seeking functionality. If I remove the FFMPEG functionality, I can stream the video and seek. The same goes for removing the seeking functionality, I can successfully stream the converted video with the file path as input rather than a read stream. Also, if anyone knows an alternative way (rather than chunking) to accomplish this as I know some clients aren't compatible, one of them being the Chromecast.
