There appear to be several discrepancies between the video I captured with RTMPdump and the source video for me FMS server. 1) The source video is mp4, however, the RTMPdump video appears to be in a flv container. Is this correct? I read something about this here http://stream-recorder.com/forum/showpost.php?p=19224&postcount=5. 2) The source video is 74.1 MB on disk (74,139,578 bytes), however, the RTMPdump video is 36.5 MB on disk (36,457,236 bytes). Why is this? Are there elementary streams in the source video that are not being transfered from the RTMP server? 3) The RTMPdump video is not seekable, however, the source video is seekable. Below is the verbose output for my stream.
