web stream HTML5 video - web_Stream_play function doesnt play

Hi Experts,

I am trying to replay HTML5 embedded video in vugen, which starts download with web_stream_open function however while adding web_stream_play - it keeps buffering and time out. however manually it works on UI.

I am using LR12.60, with 2mb size mp4 video -

below is the replay log.. 

web_stream_open started [MsgId: MMSG-26355]
Action.c(1538): Stream "https://*********************" [MsgId: MMSG-35157]
Action.c(1538): Notify: Dump-file("*************\Iteration1\t8_21_content") has been saved.

Action.c(1571): Error -35042: Stream(id=2) closed due to buffering timeout. timeout setting: 60 s, buffering time: 60 s. [MsgId: MERR-35042]
Action.c(1571): web_stream_play highest severity level was "ERROR" [MsgId: MMSG-26391]

also, I am not clear if video is of 1GB size, web_stream_open create a dump file for full 1GB or keep chunks and proceed to next web_stream_play.

any suggestions on the issue!! I wasn't able to gather much on this topic other then MF manual samples on help documents.
