@evelyn@misskey.bubbletea.dev It was apparently a standard feature of the OS it used, and also appeared in a number of other PMPs at the time, but the A320 was the only one that gained any real notoriety. I think they treated it as just another video/animation format
@evelyn@misskey.bubbletea.dev For context, this was back when ~every "MP4 player" on the market in Europe still required using weird proprietary apps to convert videos to a custom player-compatible format, and smartphones were in their infancy - having an affordable device with such a wide range of natively(!) supported video formats requiring zero transcoding upfront was nothing short of revolutionary
@evelyn@misskey.bubbletea.dev In fact, it's so interesting that a (rare) second-hand unit nowadays can easily sell for more than it used to cost brand new back then!
@evelyn@misskey.bubbletea.dev (The Dingoo A320 was generally very interesting in a lot of different ways, defying a lot of assumptions at the time, like how they actively worked together with homebrew developers and encouraged Dingux, a Linux distro for the device - all of this from what was ultimately a cheap off-brand Chinese handheld/mediaplayer. It's also a big but largely unknown part of the heritage of many handheld emulators and "tiny laptops" that exist today.)
