Description
~$ streamlink --no-config --version
streamlink 6.5.0
For at least several weeks, Pluto has not been properly filtering out ads during the ad breaks. However, the issue manifests itself differently, depending on the Pluto channel, the time or show being presented on that channel, and the particular player (VLC and MPV) being used. Depending on the channel or time or show, the ads might be filtered like used to be normal. On other channels, most or all the ads are unfiltered. Sometimes, during an ad break, the show is paused, but the audio of the advertisements play, and the stream breaks. If the user starts watching a pluto channel during an ad break, I have seen the ads run smoothly and the actual program get filtered out as though it was the ad.
The variable, changing nature of the issue makes it hard for me to select a good sample of debug log output for diagnosing the issue. A channel which is experiencing the problem today might start filtering out ads properly later in the day during a different show. Or maybe the issue exists during one day but manifests itself a little differently on the next day. I am pasting a sample debug log from a couple of days ago, from a stream which, at the time at least, was not filtering out ads but otherwise running fairly smoothly. Also keep in mind that issue #5475 is still relevant, which requires the user to know the old urls of each stream in order to use streamlink. Please let me know if this debug log is not sufficient for some reason.
Step 1: enter "streamlink https://pluto.tv/en/live-tv/star-trek-1 best --loglevel=debug --auto-version-check=True --player=mpv --player-no-close=True" (I use a config file to enter most of these options, and I use one-click launchers on my desktop Linux to enter the command into the terminal for each stream I am interested in).
Step 2: watch the stream and wait for an ad break
Step 3: observe results and hope that the stream does not break
Step 4: close out of the stream after the ad break is over and the normal content resumes
Step 5: copy and paste the debug log from the event into a text editor.
