Dear FIWARE coach,
we forward you a support request received from a CreatiFI applicant we are
not able to solve.
Please let us know if you need direct contact with the submitter.
Thanks.

*************************************

Dear

Problems: activating a recording of our video stream on KMS we get a file
that is misbehaving in reproduction in Google Chrome on Mac and Windows
platforms: the video file displays all the frames at an early stage, even
before it begins playback; once you started playback you see the last frame
(fixed) of the video, while audio is played correctly. No problem recorded
in a Linux environment.

Environment: the machine hosting KMS is our application server in the
network fi-ware of Trento. The same problem also plays on my development
machine (Kubuntu).

see in attach:
- log file of the procedure described above
- recorded webm file

can you suggest a solution

Stefano
