Hi Andreas (2020.08.29_16:06:32_+) > A totally unrelated question: What transcoding procedures could you > recomment to make sure a video can be seen flawlessly on phones and > other systems than Linux. I had trouble with my own videos - if > you have some hints - I'd love to learn this (in a smaller To: list > thought) Non-trivial question, that. MDN has some guidance: https://developer.mozilla.org/en-US/docs/Web/Media/Formats https://developer.mozilla.org/en-US/docs/Web/Media/Formats/Video_codecs Generally, the most compatible codecs are a little behind the state of the art in compression. Peertube is transcoding to h.264 High Profile + AAC LC audio, which is probably the lowest common denominator. However, these are both patent-encumbered codecs. VP8, VP9, AV1 don't have those problems. But aren't quite as widely supported. (esp AV1 which is still very new). So, no quick easy answer :) SR -- Stefano Rivera http://tumbleweed.org.za/ +1 415 683 3272
