encoding to two different H264 resolutions on imx.6

[liora]

Hi All,

I'm trying to setup a gstreamer chain that takes the camera input and encode into two different resolutions:  I get two errors on vpuenc1

negotiation problem

encoder not initialized

Does anyone have a clue about the meaning of this error ?  encoding one copy works fine as well as replacing one of the tee branch with fakesink so this is not an issue of threads etc.....

Thanks

Lior

Hello,

  Please try at first two separate (non parallel) streams with minimal

number gstreamer elements (source -> queue -> sink) – to define

what elements (parameters) are not “compatible”.

Have a great day,
Yuri
