This is a follow-up to Marcelo's e-mail on this subject from 3/2/2009.
In subsequent discussion with TI we confirmed that the likely reason this
didn't work was that the codec itself did not support 1080i encode. For this
reason, there are checks in the demo code that make sure > 720p is not allowed.
We did verify that Mahendra's changes do enable 1080i capture on our setup
(thank you very much, Mahendra!). Now we are running into a different issue --
it seems that the 1080i capture is running no faster than 15fps (even though
the encoder we are running it with does run at > 15fps for 1080i).
We are in the process of trying to figure out if this is something inherent in
the video driver or maybe something in the way the demo works. Before diving
into the ioctl code in davincihd_capture.c in the drivers directory, I thought
I'd check to see if anyone else has run into this issue (or, alternately, were
you able to get 30fps through these changes?).
We are using DVSDK 2.00.01.15 for HD DaVinci (and the DMAI 1.18.00.01 that
comes with it).
If anyone has any thoughts / can shed some light on this, please let me know.
Thank you!
Sincerely,
Robert Chen

Hi, it didn´t work.
I ran the new loadmodules.sh and received this message:
[email protected]:/opt/dvsdk# ./loadmodules.sh

Seems to be right, but when I tried to run the encode program (with the
modified capture.c), I received this error:
[email protected]:/opt/dvsdk# ./encode -a audio.aac -v video.264
> Encode demo started.
