DVCPRO is incorrectly identified as 16:9 aspect ratio. You must use
libdv from CVS or a post 0.101 release.

- mcrescale
-
- Description
-
- Scale the producer video frame size to match the consumer.
- This filter is designed for use as a normaliser for the loader producer.
-
- Constructor Argument
-
- interpolation - the rescaling method, one of:
- nearest (lowest quality, fastest),
- bilinear (default; good quality, moderate speed),
- hyper (best quality, slowest).
-
- Initialisation Properties
-
- int in - in point
- int out - out point
-
- Mutable Properties
-
- string interpolation - see constructor argument above
-
- If a property "consumer_aspect_ratio" exists on the frame, then
- rescaler normalises the producer's aspect ratio and maximises the
- size of the frame, but may not produce the consumer's requested
- dimension. Therefore, this option works best in conjunction with the
- resize filter. This behavior can be disabled by another service by
- either removing the property, setting it to zero, or setting
- frame property "distort" to 1.

- Dependencies
-
- the mainconcept rescaling sdk.

- Description
-
- BlueFish444 audio and video output module.
-
- Constructor Argument
-
- card - a numeric card id starting at 1, default is 1.
-
- Initialisation Properties
-
- string standard - "PAL" (default) or "NTSC"
- - default is based upon MLT_NORMALISATION
- environment variable, which defaults to PAL.
- int frames - the number of DMA video frames. default is 8.
- minimum is 2. maximum on my system is 11.
- int buffer - the number of frames to buffer within MLT, minimum 1,
- default 25.
- string rescale - a rescale method, see the Filters/rescale.

-
- Dependencies
-
- BlueVelvet SDK installed parallel to mlt in "bluefish."
-
- Known Bugs
-
- Does not work with any service that uses pipes!
-
- If mlt crashes, you might need to reload the BlueDriver kernel
- module due to unreleased DMA buffers.
-
- Only supports 2 channel audio at the moment.
