EXT-X-PLAYLIST-TYPE:VOD Setting

Question

Hi there,  
  
I'm using the web xonsole to test MediaConvert before building it out with the API.   
  
At the moment the m3u8 manifest files have the following at the top:  
  
#EXTM3U  
#EXT-X-VERSION:3  
#EXT-X-PLAYLIST-TYPE:VOD  
#EXT-X-MEDIA-SEQUENCE:0  
#EXT-X-INDEPENDENT-SEGMENTS  
  
However i'm looking to have them marked as VOD content, so for example:  
  
#EXTM3U  
#EXT-X-VERSION:6  
#EXT-X-PLAYLIST-TYPE:VOD  
#EXT-X-MEDIA-SEQUENCE:0  
#EXT-X-TARGETDURATION:4  
#EXT-X-INDEPENDENT-SEGMENTS  
  
I've looked through all the settings and can't see anything that would make this happen.  
  
My job JSON is included below (with a few things xxx'd out)  
  
Many thanks in advance,  
  
Stuart

Answer

Hi Sam,  
  
Many thanks for the help - i'm a little embarrased as I should have checked the child manifests, it's just the ones I was comparing against had it in the main manifest so was expecting to see it there - so thanks for letting me know and it seems fine to have it just there.  
  
Thank you also for the direction in EXT-X-TARGETDURATION  
  
Much appreciated!  
  
Stuart

Hi Stuart,   
  
What is the issue you are trying to resolve? Are you trying to add "#EXT-X-PLAYLIST-TYPE:VOD" in your manifest? This tag is already added in the child manifest.   
  
Following is the master and child manifest running with your JSON.   
  
#EXTM3U  
#EXT-X-VERSION:3  
#EXT-X-INDEPENDENT-SEGMENTS  
#EXT-X-STREAM-INF:BANDWIDTH=942707,AVERAGE-BANDWIDTH=461799,CODECS="avc1.4d401e,mp4a.40.2",RESOLUTION=640x364,FRAME-RATE=24.000  
big_buck_bunny_1_1.m3u8  
  
#EXTM3U  
#EXT-X-VERSION:3  
#EXT-X-TARGETDURATION:8  
#EXT-X-MEDIA-SEQUENCE:1  
#EXT-X-PLAYLIST-TYPE:VOD  
#EXTINF:8,  
big_buck_bunny_1_1_00001.ts  
  
If you want to set #EXT-X-TARGETDURATION:4, you can change the follow setting.  
"FramerateControl": "INITIALIZE_FROM_SOURCE"  
"GopSize": from 90 to 50 (if source's framerate is 50/25) or 60 (if source's framerate is 60/30/)   
"SegmentLength": from 6 to 4,  
  
Thanks,  
Sam
