Interlace video encoding and decoding with DMOs |
|
|
Can any body figureout exect procedure for the interlaced
configurations with DMOs.I am not able to configuring the interlaced
video encoding/decoding.
I am using Windows Media Advanced profile DMO's encoder and decoder
wrapper filters with WMFSDK95 . I am not able to passon
VIDEOINFOHEADER2 structure on input and outputs of the DMOs for the
interlace video encoding and decoding. I would like to know what other
steps that are missing for the interlaced video encoding and decoding
.. Or i have to manage VIDEOINFOHEADER to VDIEOINFOHEADER2 conversion
to finaly passon to the VMR for the interlaced video rendering. I am
realy confused how i can pass interlacing information to VMR with
consideration of the above conditions.
1. I have been written my own encoder filter based on the DMO Encoder
for passing the data unit extension. But I can not see the interlacing
information while decoding the content.
2. How i can conform that my encoded buffer having interlacing
information ?
3. Wheather i need to write my own decoder filter based on the DMO
Decoder for passing data unit extension agian during the decoding.
4. If am using VMR with high end display card in my system i need to
passon VIDEOINFOHEADER2 for the interlaced video playback. How it
could be done.
Thanks
