Thread: Multi-bitrate Streaming for Iphone, Ipad, Andorid and symbian

    Default Multi-bitrate Streaming for Iphone, Ipad, Andorid and symbian

    Good day, I am currently working with MP4 video recording 750 kbps, 128 kbps audio.

    of the problems we had before. We can solve with the new update. all is well on the pc and iphone by wifi.

    But there is a problem with 3G and 2G connections is low freezing videos on mobile.

    Now we wish to lower the bitraje of the videos up to 128 kbps to avoid this problem. what we're trying to make is with this article.

    but we have a doubt. "as stated in the kind of global variable. That is the general level" as we have more than 8TB mp4 video and want to take through a system, all the videos at the time of production, are taken in this way automatically. according to my connection.

    128 kbps, 250kbps, 320kbps, 750kbps and 512 kbps

    NOTE: pc all is well in our request is only for the phones. because currently we are working only in direct mode

    Not sure what the problem or question is. Have you seen this article on encoding for multi-bitrate delivery:

    videoe.mp4 videod.mp4 videoa.mp4 videof.mp4 videob.mp4 videog.mp4 videoc.mp4 .............. etc etc

    I'm guessing that you are asking about .smil files for multi-bitrate sets. For what you are doing, the only option is to create each smil as necessary.

    That means that if I have 1000 files mp4? create 100 smil?

    I did not understand it very clear in this case. but what we want to do is yoked a general for all files.
    since currently use this mode of recognition by php for example.
    http:// [Wowza-address]:1935/vod/mp4:<?=$url;?>/playlist.m3u8

    where "url":
    $url = mysql_query($videos);

    because here there are hundreds of records and the user can click for example.
    "Tarzan stories" = history-of-tarzan.mp4
    php and automatically place the name in order to be played.

    if not let me understand. to see the videos are uploaded every day and be saved by a system with a database.
    Deamer therefore make a global smil but help us recognize the videos.

    Normal working today because it always takes a name and that file, this is repreoduce the mobile terminal but as this work with a single smil? because we only use a VOD for all videos

    Hi netandino,

    You need 1 .smil file for each video which is encoded into several different bitrate files. For example, one smil for each video encoded as 128 kbps, 250kbps, 320kbps, 750kbps and 512 kbps.

    You cannot have just one .smil for 1000's of files. Hope this helps.

    Hi
    If you can write custom you could probably advance on the code found here,
    http://www.wowza.com/forums/content....der2-interface

    This will give you a base to work off and if the logic is correct should solve your problem.

    If you have problems or can't modify the code, then you can get a list of independent consultants.
    Email support@wowza.com and ask for the list.

    For 1 mp4 create 1 smil
    For 50 mp4 created 50 smil

    Currently I have 3865 250mb to 1.2TB files from mp4 each one does all this mean smil and codes work: (

    Now the question is if I have the 3865 MP4 videos in a single folder I have to put the smil also with a different name?

    Tarzan, avatar, etc etc? but how I recognize from my system.

    This is very tedious if you give me more work and even think.

    Ask you to be thinking about a general platform or a global module to solve this kind of detail. Because if you want to do is not for VOD 1 videos mp4, but to many to be added and are added automatically. And Wowza and must be prepared for it.

    I say this because we are also people who produce the videos, we are sent from different sites and they do not have the slightest idea of a smil. And that we create each smil generate more and more work. Since many videos are uploaded daily. This means that we have to be stuck on the server every day creating and creating and ordering smil.

    So, or I misunderstood what I explained.

    This is the best method as you can intercept the request for a file, even if it does not exist, perhaps create it , then continue.

    There may be some performance overheads the first time you created the file, so smil, and you would be restricted to the same format file each time, so all the bitrates of the files available would be assumed, but should work.
