I don’t know about videos but having a look at the OSI model is a good way to start. It covers the abstract framework for packetizing data including things like the distinction between hardware and software, envelope, encryption, application layer stuff, the whole shebang. The cool thing is by going hardware, network, application you can see where responsibility are and it helps you understand where things can go wrong.

If you are interested there are plenty of CCNA style courses available on the internet, licit and otherwise, and they go into more depth, and the same applies to RHCE/RHCSA material. The training for certifications like that covers what you want to know but also puts it in context, and again licit and otherwise sources are available.

I had a psychiatrist for my ADHD who went off the deep end on Q and Trump. It is entirely possible to get a high end degree without critical thinking skills, so seeing someone with at least 10 years of university, medical school, and specialisation in psychiatry going off the deep end is not impossible, just a bit odd to process.

That said, I think Australians tend to be a little more up front than North Americans, so when someone seems to just spew whatever they are thinking they seem more familiar. That said, someone spewing garbage should not be seen as normal but here we find ourselves I guess.

Nah, we have what we call casual racism, but the real far right intense stuff is a vocal minority. I live in regional NSW and we have a growing immigrant population, largely from Asia and Africa. The colour difference between what was here 5 years ago and now is there if you care to look but honestly it is just people being people for the most part, nobody really seems to care. That said, our billionaires are a major issue and government capture seems inevitably unless major reform goes through.

It looks like it is downsampling the video or streaming after converting to another codec. Some codecs are fine for decoding on the server but the app may not support them so the server converts them. Some files are of higher quality than what the server is configured to deliver so it downsamples to stream it.

Check the configuration and look for anything to do with codecs, hardware decoding, streaming quality, and so on. It may also be on the app, so if you can access a different interface then test that to narrow down the issue.

Something I have found is missing from both of these suggestions as well as every podcast app on device is transcoding to speed up so it is not sped up on the fly. For a lot of phones and other devices the task of playing back at 2x speed is enough to demand a higher power state than what is required to play a sped up file. For efficiency doing a single pass of speeding up the audio then playing back at that speed would use less power during the playback phase, allowing you to download and speed up all of your podcasts at home while on charge then listen for long periods without completely killing the battery. I have checked with a few if the open source devs and this is not a feature they see utility for so nobody intends to make it.
