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.
