[QUOTE="misterd, post: 266999, member: 19503"] Hi, it will be possible to change many things in the graph after 1.0. This will also include the encoders/muxer etc. A reason for not using the configuration panes of the filter is also that the configuration program doesn't have access to the filter atm. The whole graph handling etc. is completely done in the service. We try to make everything as simple as possible for the normal user. Also I'm not talking about the Intervideo encoder settings in MP. In MP you can define the frame size in the configuration dialog of an analog card. There are interfaces for the filters of the card itself (tuner, capture, ...) which can be used to set the configuration options that are available for those filters. So we don't have to implement a configuration pane for each card. And there are also standard interfaces for the encoders which we are using now. Currently we have only implemented the one for video encoders. As already mentioned each encoder can have its own minimum and maximum bitrate, so we don't use exact bitrates in the configuration. When you choose "High" in the configuration, than the TV-Server will set the bitrate to the maximum value that is reported by the encoder itself. For example the M$ MPEG2 Video encoder which is included in Vista doesn't have a configuration pane but supports the interface which we are using. This filter can't be used with TV-Server atm, because it isn't in the internal list of supported encoders, but I think that it can be used in the future. I understand that there users that want to control every possible option, but this makes it also more complicated for us to understand what is happening on the system when we get bug reports. BTW: I had a look at the code and there is already some code which sets the frame size to 720x576 (640x480) on the capture filter. Unfortunately it will be only used with HW-encoder cards atm. When I have some time I will check if we can use it for software encoder cards too. MisterD [/QUOTE]
