MPEG muxer/demuxer custom elementary stream support

Hi,

We are developing a publish /subscribe based application that streams video over a network environment.

But in this streaming data we use video and an elementary streaming that has a different format than audio elementary stream.

We've developed transport part but trying to replace it with IPP - UMC libraries.But before starting this process , we should assure that UMC fulfills project needs.

So , does UMC supports transporting video and private elementary stream?

Thanks...

Hello,

sorry for delay, our expert was on vacation. So, his answer is

Of course, private elementary streams are supported.

Important thing is that muxer/demuxer should be able to evaluate the type of data carried inside elementary stream.

Streams of unknown type will be discarded.

Regards,
Vladimir

So how should we identify this private stream AUDIO_TRACK VIDEO_TRACK VBI_TRACK ? UNDEF_TRACK is discarded due to answer.And only we know the format of private stream ,UMC or IPP has any information about it.Should we write our handler to format data?

And sorry for delay , this private stream support problem has an affect on SU development part.We'll migrate our mux/demux to IPP only if IPP support user defined private streams.

Sorry for the delay, there is developr's comment:

VBI isnt fully supported by mpeg2mux although there is some code.

He mean that there is no complete workable solution yet. This is the reason why it was not released in IPP sample.
