Once an for all, does GStreamer support .pls playlists?

GStreamer-devel mailing list
Hi.
Having troubles with playing a particular radio stream in Clementine, and
getting the reply for one of the maintainers there that "It's working for me
with gstreamer 1.18.2" whereas I have "1.14.4-1", I built from source the
latest version, GStreamer 1.19.0 and tried the following:

```
[gst-master] buster@debian:~/gst-build/build$ gst-launch-1.0 --version
gst-launch-1.0 version 1.19.0
GStreamer 1.19.0 (GIT)

[gst-master] buster@debian:~/gst-build/build$

```

```

GStreamer does not natively handle PLS. Though applications like Totem (Gnome
Video), do have various playlist parsers and can use GStreamer to play the
content.

Just tried this one in Totem, and it fails with "open: File name too long". From
what I understood it is using GVFS to access the files over HTTP, and this seems
like a limitation of it. Would have been nicer to use souphttpsrc for that, but
this is application design choice.

The playlist is the following:

[playlist]
File1=https://1fm.gscdn.kbs.co.kr/1fm_192_1.m3u8?Expires=1619111851&Policy=eyJTdGF0ZW1lbnQiOlt7IlJlc291cmNlIjoiaHR0cHM6Ly8xZm0uZ3NjZG4ua2JzLmNvLmtyLzFmbV8xOTJfMS5tM3U4IiwiQ29uZGl0aW9uIjp7IkRhdGVMZXNzVGhhbiI6eyJBV1M6RXBvY2hUaW1lIjoxNjE5MTExODUxfX19XX0_&Signature=mnNon5XupF~K1FJ2mdzn-k~ffjgnM4zlTxLI19pfnGuHbfBtjjw2ojGZdn862qkHfAFhnM85hqAM6CryIsi2HC8nrduJrlaCJHC0TGwcv2N9kQaHRdYfJCw12O0r9ChkE48ldqgxkg7cYqPfIdvlAbxoAv1yL-ogVER6o4OdGtbBS5LCiaLZ0b6svpA6FbtKuLHhCAJnupkNyrf97cbgHMnwXTNVeKs5u3uiSvNMAW3LLgKVfuOIzbwvJxKkNlKbXg05YKkRaSJgHzCPk9ucM1Ka6XSOpPmxkqcHKCV~mWJC199qKzcAivbNKqUlXfBCzQYIaNfwTLoHtGT7KoBqUg__&Key-Pair-Id=APKAICDSGT3Y7IXGJ3TA
Title1=KBS Classic FM
Length1=-1

So it points to an .m3u8 playlist, this one is special playlist, it's an
adaptive HLS stream, which GStreamer handles natively. You can test with:

gst-play-1.0
"https://1fm.gscdn.kbs.co.kr/1fm_192_1.m3u8?Expires=1619111851&Policy=eyJTdGF0ZW1lbnQiOlt7IlJlc291cmNlIjoiaHR0cHM6Ly8xZm0uZ3NjZG4ua2JzLmNvLmtyLzFmbV8xOTJfMS5tM3U4IiwiQ29uZGl0aW9uIjp7IkRhdGVMZXNzVGhhbiI6eyJBV1M6RXBvY2hUaW1lIjoxNjE5MTExODUxfX19XX0_&Signature=mnNon5XupF~K1FJ2mdzn-k~ffjgnM4zlTxLI19pfnGuHbfBtjjw2ojGZdn862qkHfAFhnM85hqAM6CryIsi2HC8nrduJrlaCJHC0TGwcv2N9kQaHRdYfJCw12O0r9ChkE48ldqgxkg7cYqPfIdvlAbxoAv1yL-ogVER6o4OdGtbBS5LCiaLZ0b6svpA6FbtKuLHhCAJnupkNyrf97cbgHMnwXTNVeKs5u3uiSvNMAW3LLgKVfuOIzbwvJxKkNlKbXg05YKkRaSJgHzCPk9ucM1Ka6XSOpPmxkqcHKCV~mWJC199qKzcAivbNKqUlXfBCzQYIaNfwTLoHtGT7KoBqUg__&Key-Pair-Id=APKAICDSGT3Y7IXGJ3TA"
