Declaration
property PlayerForcedCodec: string read GetPlayerForcedCodec write SetPlayerForcedCodec;
__property wchar_t *PlayerForcedCodec=read=GetPlayerForcedCodec, write=SetPlayerForcedCodec
Property PlayerForcedCodec As String
Description
Used to specify particular codecs to be used by TVideoGrabber.
TVideoGrabber automatically selects the default appropriate codec to play a given clip.
However in some cases a different codec can be preferred. E.g. to play MPEG2 clips you can prefer the Elecard/Moonlight video decoder instead of the Intervideo video decoder.
Note that adding codecs to the graph can be achieved also by invoking ThirdPartyFilter_AddToList (tpf_AddToGraph...
To use the default codecs, leave PlayerForcecCodec emtpy.
To force the use of a given codec, simply assign to this property:
- either a significant part of the codec name,
- either the CLSID string of the codec.
E.g.:
VideoGrabber1.PlayerForcedCodec "= "Elecard MPEG2 Video Decoder"
or
VideoGrabber1.PlayerForcedCodec = "F50B3F13-19C4-11CF-AA9A-02608C9BABA2"
PlayerForcedCodec keywords
The following keywords are supported by the PlayerForcedCodec property:
PlayerForcedCodec = "NOFFDSHOW"
Prevents TVideoGrabber to use the FFDSHOW codecs when they are enabled by default on the current platform.
PlayerForcedCodec = "NOMPC"
Prevents TVideoGrabber to use the MPC (Media Player Classic) codecs when they are enabled by default on the current platform.
PlayerForcedCodec = "AVS"
enables the playback through AVISynth when AVISynth is installed
PlayerForcedCodec = "FFDSHOW"
enables the playback through FFDSHOW is the FFDSHOW video decoder is configured to decode the format to be played.
All these non-default settings can be restored to their default value by setting PlayerForcedCodec = ""
Note that reading the PlayerForcedCodec string does not reflect the state of these keywords, only codec names or codec CLSIDs appear in the PlayerForcedCodec string.
