+ | ---- | ||
+ | The script opens mpv with all active (currently streaming) streams from [Chaos Computer Club](https:// | ||
+ | Optionally it can also try to open all streams given in a valid playlist. | ||
+ | |||
+ | First make `strobs` executable with `chmod +x strobs`. Then execute `./strobs`. | ||
+ | Install mpv if not existing. | ||
+ | |||
+ | |||
+ | == Options | ||
+ | Usage: strobs [ -d | -D | -f | -h | -j | -k | -m | -n | -p _file_ | -s | -t | -v | -V | -x] | ||
+ | * -d debug mode: print commands and arguments while executed | ||
+ | * -D debug mode: print script lines while read | ||
+ | * -f forces (with -p / -j) open playlist / download full json | ||
+ | * -h help shown | ||
+ | * -j json export to disk | ||
+ | * -k keys/ | ||
+ | * -m man page shown (`strobs.1` needed) | ||
+ | * -n name stream with technical extension | ||
+ | * -p playlist _file_ with servers in format m3u8 | ||
+ | * -s sort server list alphanumerical | ||
+ | * -t timetable of running and coming events shown | ||
+ | * -v verbosity increasing with _v_ | ||
+ | * -V version print | ||
+ | * -x exit before mpv, keeps current-playlist.m3u8 | ||
+ | |||
+ | ==Details | ||
+ | The script downloads [http:// | ||
+ | It reads then [https:// | ||
+ | With this informations it builds a playlist in m3u8 format and starts mpv with this playlist. | ||
+ | |||
+ | == Examples | ||
+ | * `strobs` - opens current streams in mpv. | ||
+ | * `strobs -p 36c3.m3u8 -s` - uses the playlist 36c3.m3u8 for mpv. In addition it will sort the returned streams alphanumerical. | ||
+ | * `strobs -j -f` - will download and save status\_liveber.xsl, | ||
+ | |||
+ | == Files | ||
+ | * `current-playlist.m3u8` - generated playlist while running | ||
+ | * `input.conf` - user-defined key bindings for mpv | ||
+ | * `keys.lua` - script with key bindings for audio, video and rooms | ||
+ | * `strobs` - the shell script to execute | ||
+ | * `strobs.1` - man page | ||
+ | * `voctocat.png` - image used as last playlist item, so mpv does not stop | ||
+ | |||
+ | Only `strobs` is absolutely necessary observe running voc video streams. | ||
+ | |||
