AFAIK video decoding generally has its own chip, at least for supported codecs, separate from the GPU.

- mirimir 7y agoCan those things be exploited for other purposes?
- craftinator 7y agoSure. I've used the H264 encoder/decoder in lossless mode on the raspi3 compress large amounts of sensor data. You just need to format the data into image frames. It worked very well, and ended up being bottlenecked by the io bandwidth of the system.
- mirimir 7y agoDoes raspi3 have real gigabit Ethernet?
- masklinn 7y agoNo, that's a headline feature of 4. 3B+ has a GigE adapter working over USB2 so you can get ~200Mbps, on other models you can get an off-board adapter providing much better performances than the on-board one but still not "real GigE": https://www.jeffgeerling.com/blogs/jeff-geerling/getting-gigabit-networking https://www.jeffgeerling.com/blogs/jeff-geerling/getting-gig...
- lostgame 7y agoI’m not sure, that’s a great question. Practically, I’m not sure how that could be of use but I have seen some amazing things come out of the several processors in, for instance, SEGA Saturn homebrew, with chipsets certainly making innovative unintended uses, or at least insanely creative use. Here’s an example of what an H.264 decoder chip would be like: https://www.digikey.ca/en/product-highlight/s/system-on-chip-technologies/h264-hd-video-or-video-audio-encoder-decoder-modules https://www.digikey.ca/en/product-highlight/s/system-on-chip...
