Perhaps I'm overstating the situation.
Yes, I was referring to any kind of hardware acceleration. My immediate context was an Epia board, which would have VIA's flavor of XvMC. However, even assuming no hardware acceleration for MPEG2, I would assume that MPEG4 results would correlate with MPEG2 results. It's an imperfect, yet nonetheless simplifying, assumption. Anyway, what's a good benchmark? Ripping a DVD seems like a reasonable task for benchmarking the combination of raw MPEG2 decoding and MPEG4 encoding performance, and we could probably agree on a specific DVD. How to benchmark playback, though? JB _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
