Can EMS change the bitrate/resolution of my video stream?

In order to change the bit-rate of a video stream, the video needs to be completely decoded and then re-encoded at the new bit-rate. This is a very computationally intensive process. The EvoStream Media Server focuses on the efficient distribution of media streams, and so does not usually handle the decoding and re-encoding of data. However, if your CPU has extra cores at your disposal, you can use the EMS transcode API command to do this.
