Is there support for SVC encoding/decoding?

[Mal Pirie]

Does gstreamer support H264/SVC encoding and decoding.  Does it support adaptive streaming, i.e. is there a plugin that will strip away the extra layers depending upon some feed back from downstream?

Thank you.

Does ffmpeg support it?
Take a look at avdec_h264 in gst-ffmepg.

ffmpeg doesn't support SVC, there is an open SVC decoder called "Open
SVC Decoder", but I don't think anyone has bothered to wrap it.

One of the reasons for that is that there is no open source SVC encoder
and writing one is entirely non-trivial. But if one licenses a
proprietary one, then it would be relatively easy to wrap it. I guess
the lack of an encoder explains that no one has written a layer-pealing
plugin.

Thank you for the information.

Is there a plugin that will remove temporal layers, since this is supported in AVC?

Mal.

Thanks for taking the time to explain the situation and why it is this way.
