Video Codec Libraries
The goal of this list is to list the potential encoders and decoders that are available to use, and review what the potential licensing and/or patent issues there might be with each of them. We will be focusing only on codecs that may be suitable for review. The hope is to identify what could be included in precompiled applications without requiring any licensing costs, or side effects (like GPL).
