I belive live555 don' t support yet h264/SVC :(<BR>
<BR>
look from openSVC with there modified MP4box for SVC, you can hint the SVC.264 in a standard MP4 cointainer wich "H264VideoStreamFarmer" can use.<BR> <BR>

<P class=ecxMsoNormal><SPAN style="COLOR: black" lang=EN-US>Thats right. I mean that SVC stream is a container with up to 9 layers (3 temporal and 3 spacial), where each layer could be represented as an AVC stream. It is possible to extract the needed layer with i.e. “svcext library”. But I want to do that with the help of live555. </SPAN></P>
<P class=ecxMsoNormal><SPAN style="COLOR: black" lang=EN-US>Processing SVC stream with </SPAN><SPAN style="FONT-FAMILY: 'Courier New'; COLOR: black" lang=EN-US>"H264VideoStreamFramer" produces a .ts file with spacial layer equal to 0 and temporal layer also equal to 0. And my question was about extracting a user-defined layer to save it in a .ts file. I use as an example testH264VideoStreamer application from the original library package.</SPAN><SPAN style="COLOR: black" lang=EN-US></SPAN></P>
