Container types and efficiency
This may be dumb, but my question is: How much does the container type affect CPU efficiency? Or is it what's on the inside that counts?
I've become more and more involved in live web streaming and I'll hear people say things like "We're going to H.264 so it will be way more efficient than flash. The CPU difference is dramatic." And I think "most flash these days is H.264." Assuming the same H.264/AAC stream inside, does it make a big difference whether viewers are watching an MP4, flash file, or H.264 (though an H.264 file would be video only, right?)? But it's also very possible I'm just naive. Which is why I ask the guys who really know their stuff.

I guess the difference in decoding time between a .flv, .mp4 or .mkv container will be minimal compared to what the actual content takes. Also you can use .mp4 files with AVC and AAC in flash. IIRC Adobe even recommends the MP4 container over FLV for that use.

Now there is slight bandwidth overhead with some container formats (I recall AVI had slightly higher overhead than MP4, for example), but it's also not particularly significant. Quote:
