Even though the h.264 Pro Recorder is currently not Direct Show compatable I am wondering if it will be supported in future versions of FMLE? Blackmagic did release a SDK which a few people have begun using the help make streaming support available for this device. Currently there is MX Light as well as Livestream which now support it but the options are limited.
The potential for this device to free up CPU usage as compression is already done could make it one of the best capture for streaming devices currently on the market as there is no post processing needed.
