Thread: pixel aspect ratio

  1. #1

    Default pixel aspect ratio

    Hi there,

    How to change the pixel aspect ratio using WOWZA transcoder ?
    kindly let me know

    You can use <FrameSize> <FitMode> of "stretch" and then set up the frame size to the desired aspect ratio.
    This produces 16:9 aspect ratio.

    And a width of 1080 and height of 720 produces a 3:2 aspect ratio, and so on.

    Thanks Salvadore for the clarificationl.

    However I have another question.
    I have been trying to create a playlist. I have a smil file


    <stream name="Stream1"></stream>
    <stream name="Stream2"></stream>

    <playlist name="p11" playOnStream="Stream1" repeat="true" scheduled="2013-07-18 14:40:00">
    <video src="nc_prog_ba_sd_prog_ba_pivot_18.ts" start="5" length="5"/>
    <video src="nc_prog_ba_sd_prog_ba_pivot_132.ts" start="5" length="5"/>
    <video src="mp4:sample.mp4" start="50" length="5"/>
    <video src="mp4:sample.mp4" start="150" length="5"/>
    <video src="mp4:sample.mp4" start="250" length="5"/>
    <video src="mp4:sample.mp4" start="175" length="5"/>

    But I cannot play the .ts extension files using this url in safari browser
    http://<wowza ip address>:1935/live/Stream1/p11.m3u8

    but I could video the videos with mp4 extension

    Could you kindly let me know if there is some configuration Im missing ?

    also this is what error log shows
    WARN server comment 2013-07-18 16:05:50 - - - - - 4.544 - - - - - - - - Metadata appears to be bad: Stream1

    Hi Manoj,
    .ts files are not a supported file format for streaming.
