You can simply place 32-bit dll (from http://www.trichview.com/forums/viewtopic.php?t=6880 ) in the same folder as your application, and RVMedia will be able to use it.

Note that RVMedia uses FFmpeg only for receiving video from a camera or external video streams. When communicating between TRVCamSender and TRVCamReceiver, our own video format is used; basically, jpeg images (of the full frames or changed fragments) are sent. I.e. the current version of RVMedia does not use FFmpeg when sending video to the network.

As I said, RVMedia does not support video + audio encoding using FFMpeg or GStreamer.
It sends video and audio in its own format. Video frames are sent as jpegs, with possibility of sending only changed fragments.
Audio is sent uncompressed by default, but can be zip-compressed if you specify CamSender.CompressionOptions

RVMedia supports sending files. So you can encode video + audio in a file, then send this file, and then play the received file. However, RVMedia does not have functions for video+audio compression, you must do it yourself.
