vaapiencode in push mode

[Cyril Baletaud]

Hi all,

My application use appsrc to push GiGE Vision buffer in a live pipeline.
I want now to record the stream in h264 ts mux.
With vaapi element : appsrc -> queue -> tee ->queue ->vaapipostproc ->
vaapiencode_h264 -> mpegtsmux -> filesink

The link failed with :
