Oh, cool. I didn't see H.262 in the list of supported codecs, so I thought it wasn't allowed.I don't test using H.263 but I tested mpeg2video (aka H.262) and it runs around 20~30fps(depending on scene) on o3ds.
Oh, I misunderstood. Sorry about that. Isn't this a bug, though? The upper screen is 800x240, isn't it? It doesn't make much sense to encode 800x480, only to have it downscaled to 800x240 during playback, since 800x480 will take many more CPU cycles to decode and will use more space on your SD card.I mean here is that drawing library consider top screen as 800*480 not 800*240 if 800px mode is enabled.
For example, if you look at HoriHD-Gallery, the screenshots for 800px mode are 800x240, not 800x480.
