  • adaptives links for mpeg dash on wowza server not working, status error 404 Not Found

    12 août 2015, par jobin

    adaptives links for mpeg dash on wowza server not working with me, the following are the steps that I used to publish video on wowza :

    1. I install and configure Wowza server, and I tested it and it is working fine.
    2. Transcode this video using ffmepg (I bring these command from wowza documentation) :

      set inputFile="C :\video\sintel.mp4"
      set outputFile="C :\video\sintel"

      ffmpeg -y -i %inputFile% -s 320x180 -y -strict experimental -acodec aac -ab 64k -ac 2 -ar 48000 -vcodec libx264 -vprofile baseline -level 30 -g 48 -b 200000 -threads 64 %outputFile%_320p.mp4

    3. I test the files and all of them workig fine then I moved these files to wowza content folder and create the smil file as following :

    1. I use the mpd file (http://191.237.26.137:1935/vod/smil:sintel.smil/manifest.mpd) with http://www.jwplayer.com/innovation/roadmap/mpeg-dash/

  • Use FFMPEG to generate MPD files for MPEG-DASH adaptive streaming

    9 octobre 2020, par CMOS

    So I am trying to setup adaptive streaming and I have what I think is 80-90% of the problem finished. Right now I ingest my source video, transcode it into 5 resolutions each with 3 bitrates (low, medium, high) and then I split all of those videos into 5 second chunks so that the user can always have the best viewing possible. Now I am at the point where I need to generate / create my MPD manifest file and I am having a hard time figuring out how. Almost everyone just says to use MP4Box but their license is too restrictive for my project.

    &#xA;&#xA;

    Is there anyway to generate a MPD file using FFMPEG when I segment my video ? or maybe generate a HLS that I can then convert into a MPD manifest ? Any info would be awesome, this is my current FFMPEG command (working)

    &#xA;&#xA;

    Note the $ variables are inputs into a bash script that set the input file, bitrate and scale.

  • | NGINX | FFMPEG not creating DASH manifests or chunks in the designated DIR |

    7 avril 2020, par Mathew Knight

    Hopefully someone can help here, I have a setup that takes two input RTMP streams from two separate machines into my server. From here I am trying to serve some MPEG DASH manifests and chunks to an experimental spatial audio/360 web (.js) player.

    &#xA;&#xA;

    My issue is that while i can see the FFMPEG processes running and creating the Chunks the files themselves are not appearing in the specified folder and so the media player will not read the content.

    &#xA;&#xA;

    Is there something obvious that i am not doing that is preventing these files being written ?

    &#xA;&#xA;

    Any help with this would be amazing !!!
