[Live-devel] SVC -> AVC

[Joao Almeida]

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

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. 
Processing SVC stream with "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.
