This was filed as bug 197410 and fixed. It seems that even after the fix the playback of those streams is much slower than in WebKitGTK 2.24.0. Here are the steps (as reported by a Debian user): --------------------------------------------------- 1) Go to http://radio.dos.nl/ 2) Go to settings (drop down in right top corner) 3) Click "Choose protocol" until it shows HLS 4) Click on arrow (back to radio) 5) Click on "Page menu" (bottom left corner) and choose "news" 6) switch between the BBC stations (they're all HLS) (check the Info button on the left top corner, at the bottom of the info page there is the protocol that is used, it should show "HLS") 2.24.0 takes only tenths of a second (switches almost immediately), 2.24.1/2.24.2 takes several seconds. This is an issue that shows up with HLS stations. 2.24.0 switches much faster anyway. --------------------------------------------------- In addition to that there's also this problem, reported by the same user: --------------------------------------------------- switching too fast between two HLS stations (e.g. 5 Live and BBC Worldservice) makes the whole beast hang. No way anymore to switch between stations. Note: I use a Debian unmodified version of the "surf" webbrowser to play these stations. I need to stop "surf" in order to make it work again. --------------------------------------------------- There's another regression that I filed as bug 198376 which might be related to this one. I chose to file them as separate bugs for the time being.
