Microsoft Smooth Streaming playback issue

[Majaja]

Dear all:

I have met an issue in MSS.

It is, in the test link below, GSTMSSDEMUX will request each fragment but without MOOV BOX.

http://playready.directtaps.net/smoothstreaming/

http://playready.directtaps.net/smoothstreaming/SSWSS720H264/SuperSpeedway_720.ism/Manifest

It is bacause we cannot (at least, I found none) control to request the header (FTYP + "shaped MOOV")

as dealing fromal fragmented MP4 file.

FFMpeg will regard the action as a failure since it has not gotten, ex MVEX BOX in advance (before handling each fragment).

Has anyone had met this isse?

Does anyone know if there is a solution?

Thank you.

Seems to work fine here with latest GIT master. Please retest with that
version and otherwise file a bug at https://bugzilla.gnome.org against
GStreamer/gst-plugins-bad.

Hi Droge:
Do you know how the latest GIT master overcome this problem?

I mean the parser(demuxer) of FFmpeg  (mov.c) will make some checks.

But I cannnot find the flow to fix it even I have ported the latest MSSDEMUX according to your suggestion. I still see the first data from SoupHTTP is the first MOOF segment instead of the "shaped MOOV" box.

Could you kindly provide some suggestion please?

Thank you.

I have no idea, you'll have to try yourself with the code and follow
what exactly happens. There were hundreds of changes related to
smoothstreaming and adaptive streaming in general.

You can always try git bisect, find the first commit in which things were OK and compare with what you have now. 

Cheers

Check that the player volume isn't muted. Check that your system volume isn't muted. Check that your audio device is plugged in and turned on. Check that your "playback device" in the settings of Windows are set the correct device
