Scene7 html5 video player buffering time is more than eexpected

[ankitv12295055]

HI Team,

Scene7 HTML5 video player start the video with good speed but in the middle, it takes much time buffering, is there any bitrate setting that can be applied here?

Hi @ankitv12295055,

As far as I know, even with default settings it should work fine. I suggest you to test with the actual end URL of scene5 video and entering that URL in the browser window which will itself load a HTML5 modal and play in your browser rather than including it in your AEM component and then testing.

Also, what is the media type and size you're trying to access? Have you tested this on different network as well?

Hi @ankitv12295055,

I checked the video page and found that the Scene7 URL is https://s7mbrstream.scene7.com/hls-vod/agilentstage/_media_/21c/21c05e4f-6b17-4d1c-a088-77a6df24500c...
This URL has multiple fragmented TS files which are responsible for playing the video. This file has 56 fragments.

I observed that buffering occurs if fragment is not loaded with 200 response. In my case as well, there was buffering for fragment 18 and 27 and both requests failed with 503 response - Service Unavailable. The CORS error issue I fixed by modifying the headers using chrome extension.

My question:
1. What is this type of media? .mp4.m3u8? Is it accepted format by Dynamic Media?
2. Have you tried with other media type say a sample file of 8 minute with mp4 type?
3. 503 response is intermittent, but I think its related to CDN/Scene7 delivery server. You can consider raising a ticket with Scene7 Customer Support.

Hi @Jineet_Vora, The video type is mp4, yes I have tried with more mp4 videos, problem is there mainly in seeking video to forward and backward.
