is it acceptable if the encoder enforces some restrictions on the used features ? most general h264 likely cannot efficiently be decoded in lower resolution with acceptable quality Restricting the used intra modes may make it possible to do it though i dont know what the quality would be but better than without restrictions [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB In fact, the RIAA has been known to suggest that students drop out of college or go to community college in order to be able to afford settlements. -- The RIAA
