If you meant something else, could you please double-check the spelling or provide more context (e.g., field like video encoding, materials science, finance, biology, or a typo for something like H.264, PPP, PPE, etc.)? That way I can put together a useful guide for you.
I’m unable to find any verified or clear information about something called “pppe264.” It doesn’t correspond to any known standard, technology, codec, protocol, product, or research term I can identify. pppe264
