Dear Friends, For http://www.kdenlive.org project, I am trying to determine the hardware requirements to decode h264/AVCHD interactively.
When using AVCHD camcorder, we would like to inform end-users of hardware requirements. I know hardware acceleration is coming along with Nvidia VDPAU patch that we ***may*** implement in MLT, depending on development resources. Until then, we rely entirely on FFmpeg optimisations and multithreading. My questions: * Is anyone with a dual-core/quad-core computer able to decode one of these movies interactively: http://www.kdenlive.org/videos/avchd-test-1.mts http://www.kdenlive.org/videos/avchd-test-2.mts http://www.kdenlive.org/videos/avchd-test-3.mts http://www.kdenlive.org/videos/avchd-test-4.mts http://www.kdenlive.org/videos/avchd-test-5.mts These files come out a HD AVCHD camcorder. Use ffplay to test. If one movie plays in slow motion, others will. No need to test everything. My dual-core computer is not able to decode interectively any of these movies. * Does h264 and AVCHD use sliced decoding which I saw in SVN? Is h264 decoding really multi-threaded? When using ffplay, I see only one core working at 100%. How to activate multi-threading decoding. Can we expect to decode AVCHD with a quad-core? Thank you for your answers. According to your information, we will publish information on kdenlive web site.
