Uwe,

I am not sure about the use case here, so can't give you
specific
answer. Have you considered using
CVideoPlayerUtility::OpenURL ? 
If it is SDP initiated multicast then you may pass the SDP
file directly
to CVideoPlayerUtility::OpenFile. In both the cases,
CVideoPlayerUtility
would be able to play live streams. H/W accelerated  codecs
would be
used if available on the phone. No additional efforts are
required from
the user to use the h/w accelerated codecs.

Thanks
Ashish

Hi and thanks for your response Ashish,

So I can forget using xps and will have to write an mmf
controller(sigh). At least I hope that I can use the
hardware
accelerated codecs. If you have any advice or could tell me
what I
should look at please let me know.

Thanks,

Uwe

Hallo Ashish,

The application was developed some years ago for the S90. It uses a datastream broadcast on DVB-H demuxes it and writes the audio to CMdaAudioOutputStream and draws the videoframes using CDirectScreenAccess. The demuxing has to be done in the application because the stream contains text and application data also.

I have to get this application working on S60 3rd with N96 and N77 and the main missing pieces are the codecs. I would like to use the preinstalled hardware accelerated codecs. At first I thought I would use the MMF but there seems to be no way of passing encoded frames to it. I could create a new stream from the demuxed video and audio but then it seems easier to just use CMMFCodec directly. If you have any other suggestions I would be glad to hear them.

Thanks for your help,

Uwe

Hallo,

I am working with a live stream containing a video stream that has to 
be displayed on a Nokia device. If I understand the xps correctly I 
could pass the video frames to it and let the Helix controller handle 
decoding and display. The latest Nokia devices with live video 
capability have the RealPlayer preinstalled - some of it hardware 
accelerated. My questions are:

1) Is it possible to use xps with the preinstalled RealPlayer engine 
to display a video stream on a Nokia device ?

<Ashish> No. XPS is part of helix. Nokia S60 3.1 and  prior devices 
use installed realplayer (or microcore).

2) Is xps part of the RealPlayer engine or does it have to be 
installed ?

No. XPS can't be installed on pre-installed real-player as it is 
tightly inetegrated with Helix Client.


3) Is there documentation available for the xps api or do I have to 
look at the source ?

I would start looking at datatype/xps/test.


4) Do we need a commercial license to use the xps ?

<Ashish> I am not expert on the licensing issues but I guess usual 
helix community licenses should help. You can get better response from
    

  
helixcommunity.org">licensinghelixcommunity.org.


Thank you for your help,

Uwe
