Thanks to Daniel Verkamp for contributing a Kega video (KGV1) decoder to FFmpeg<\/a>. I was about to demand samples for testing until I looked up what Kega is — a Sega game console emulator — when I realized that it would be more fun to create my own (be advised that only the Windows version of Kega<\/a> presently supports the AVI encoding option). Then I looked up the Wiki page<\/a> and realized that there is, in fact, one sample on record at the archive. Well, I went ahead and made my own sample anyway. I used the mountainside attract-mode scene from the Genesis game Strider<\/a>, one of my favorite sequences in any video game. It’s in the samples directory<\/a>.<\/p>\n

I am holding off on adding a FATE<\/a> test; there’s still an endian issue (PPC configs disagree with x86 configs). I’m also a little puzzled as to why FFplay insists on playing the video as 320×240 even though the video is encoded as 640×480. For that matter, I’m also bewildered trying to understand why Kega renders video as 640×480 by default; that’s not a native resolution for any of its emulated consoles.<\/p>\n","protected":false},"excerpt":{"rendered":"
