h234 topic hijacking

Has anyone had any luck outputting H264? I kept hearing that it's the latest, greatest codec, makes much smaller output files, brings you breakfast in bed, etc. But after trying a variety of output options to ffmpeg, the best I could come up with something that had the same quality as the normal quicktime .mov's I'd been producing, but took 15 minutes to create instead of the usual, whatever low number (negligible, or I'd remember it.), and ends up about the same file size.

Encoding to H.264 takes tons and tons of CPU time and I doubt it's really worth it, even to do it on the fly with transcoding. The best option would be having a hardware H.264 encoder / decoder - but it would defeat the way Zoneminder works.
