<tr valign="top"><td rowspan="13">90<td><tt>OMX_IndexParamPortDefinition</tt>
|
|
<td> Sets the port definition type to describe the input video
|
|
stream. Typically this is called by the component itself when this
|
|
port is tunnelled with an appropriate output port. This port also
|
|
supports setting the port definition to an image domain, which allows
|
|
connecting this port with an output image port - for example from a
|
|
still image decode.
|
|
<tr valign="top"><td><tt>OMX_IndexParamVideoPortFormat</tt>

with a number of different pixel formats.

scaling is implicit in the destination rectangle specified via

Must be less than or equal to 2. If 0 (default), buffers are allocated
