    Question RTSP syntax


    I have a mp4 file that I want to stream (on demand). I can do it successfully with this URL:


    But I cannot do it with this one:


    I have used ffmpeg previously to transcode "myfile.mp4" into h.264 AVC format.

    What's the difference between both URL? Is there any difference in terms of performance?

    Thanks in advance, regards!

    If the stream plays with out the mp4: prefix it means the the file is really a .flv file with an .mp4 extension.
    if you do not use a mp4: prefix, Wowza assume it is .flv, since that works it is .flv

    Hi Salvadore!

    The thing is, the mp4 file I transcoded was the one in the article you say. As far as I know, that sample file (Butterfly_HD_1080p.mp4) isn't in FLV format but in MP4. I used one of the ffmpeg commands in the article to transcode the sample file so as to stream it later.

    The player I use couldn't open the URL [rtsp://] but it could without mp4:

    From what you say... using mp4: in the URL doesn't have anything to do with performance, am I right?

    Correct, the prefix has nothing to do with performance.
    Adding mp4: prefix is necessary when it is necessary and not when it is not. You don't have a choice when it is.
