The idea of encode tunneling is to use video buffer directly for
encoder,
but currently the encoder doesn’t support interlaced surface, the OMX
decoder set progressive surface before on that purpose.
Since now we are polling the driver for interlacing information for
decoder, we got the interlaced as preferred as other APIs(VDPAU,
VA-API),
thus breaking the transcode with tunneling.
The solution is when with tunnel detected, re-allocate progressive
target
buffers, and then converting the interlaced decoder results to there.
This has been tested with transcode results bit to bit matching as
before
with surface from progressive to progressive.
