I’m equally interested in ad filtering when external tools use yt-dlp just to extract an M3U URL with -get-url or -dump-json.

Obviously native HLS downloader can be fixed and adapted to filter ads but it would cover just that i.e. Related issues are, Yt-dlp side of thingsĪs far as I understand native HLS downloader doesn’t support Twitch at all because yt-dlp always † switches to ffmpeg. I’m not sure if any of them work right now. #+js(json-prune, /^X-TV-TWITCH-AD/)Īt some point there were server side ways to prevent Twitch from serving you ads at all by cloaking as specific ad-free client. There is also a filter list for uBlock Origin for web based player. Or any(attr_key.startswith('X-TV-TWITCH-AD-') for attr_key in daterange.x.keys()) Or str(daterange.id or '').startswith('stitched-ad-') Here is how streamlink feature –twitch-disable-ads works.ĭaterange.classname = 'twitch-stitched-ad' At worst you get a few seconds gaps in a stream but you don’t get full length ads either. My understanding is it involves stripping-filtering-skipping ad segments from an M3U based on their # comments. There are well known tools that successfully deal with Twitch ads.

There are no embedded ads if you download VODs (at least for now). Twitch does this only to live streams and reruns. Both prevent you from getting actual stream content. Mid-roll ads can take up to a few minutes. They usually take about 15 seconds to finish. Pre-roll ads play right after you start grabbing a live stream. It doesn’t contain actual ad streams but you get placeholder segments lasting as long as ad would. Twitch has a system that embeds ad segments directly into an M3U playlist.

I’ve searched the bugtracker for similar site feature requests including closed ones.

I’ve verified that I’m running yt-dlp version 2021.09.25.
