Hi I am new to github so please excuse my poor etiquette. I too was trying to download shrouds first vod on mixer. I also previously have had issues downloading videos and after some googling and reading around on youtube-dl issues, I found the "" quotes trick. What I learnt from that first experience trouble shooting was to look around the webpage using the browsers inspector. This is the method I used previously to fix my issue of downloading videos from roosterteeth.com. The visual tool that allows to select elements and by hovering over the video playing and going to to video player src= attribute and finding the akamaized cdn url. Since the akamaized src attribute had a key pair that had to be enclosed in quotes to be accepted as a good valid url to youtube-dl. I tried the same thing on the shroud first mixer.com vod and there wasn't src attribue that would be accepted as a download url on youtube-dl. So I digged deeper using the network monitor in the browser. Using that I could see each video .ts segment being downloaded on mixer. I snooped around more and found this url https://mixer.com/api/v2/vods/h3nT6aCznEezn6d4Em33aw once I visited this I got back some json and in that json there was an url with the locatorType: SmoothStreaming https://vodcontent-5001.xboxlive.com/channel-103551540-public/e9d37987-b3a0-479c-b39f-a778126df76b/manifest.m3u8?__gda__=2202937527_4faa4e6c116e84de66df25c29f6002e0 . I chopped of the end until .m3u8 . I used that url on youtube-dl and it worked like a charm. If any developer wants to use this info and fix the mixer download and roosterteeth download function in youtube-dl that would be much appreciated. If you have any more questions feel free to message me. I apologize for being so rambly I am new to github any constructive criticisms would be apprenticed. Thanks
