Hi, are there any open source DRM implementations for protecting Theora streams over RTP? I only know of the ISMACryp specification which seems to be licence free and so could be used in an open source project. Regards, Franz

Hi, is there a good concept to lower the quality of a Theora stream without completely reencoding it? For example to make a lower bitrate stream out of a higher bitrate stream on the fly on some sort of proxy server. I am thinking about something like requantization. If you think requantization is also the best (or the only) option for Theora please let me know. Kind regards, Franz

Hello, I am very slowly working on the NHW Project.I recently made a speed comparison with x265 and wanted to share it with you. On my processor Intel Core i5-6400, in average the NHW encoder (totally unoptimized) is x10 times faster to encode than x265 (png decoding time removed), in average 30ms vs 300ms for a 512x512 24bit color image, and in average the NHW decoder (totally unoptimized) is

As far as my very limited knowledge goes the Theora video format is less complex than H.264 (High Profile for example). Please correct me if I am wrong. Does this also mean that I can expect that decoding a Theora stream is easier/faster to decode than a H.264 stream with comparable quality / or comparable bitrate? My (very practical) tests do show that it's easier for my computer to
