--- Comment #48 from Julien Isorce <julien.isorce at gmail.com> ---
This is a very good point! And it looks like "omxh264dec ! omxh264enc" is
already working with dmabuf on Zynq right ? ( omxvideodec -> OMX_AllocBuffer ->
pBuffer is a dmabuf -> OMXUseBuffer -> omxvideoenc), Guillaume do you confirm
it works with current upstream gst-omx ?

I knew about the decoder since I reviewed some Guillaume's patches but I missed
those for the encoder or I thought it was specific to use with v4l2.

And the requirement for the OMX headers is small, just 1 struct, 1 enum and 1
index:
OMX_ALG_PORT_PARAM_BUFFER_MODE
OMX_ALG_BUF_DMA
OMX_ALG_IndexPortParamBufferMode

Just do double check before I make a request to Tizonia to add something
similar to its Ext headers too, there will be no issue with licence, correct ?
