EXT-X-PLAYLIST-TYPE:VOD Setting

0

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

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

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
