bug#41743: gst123

[Kyle Andrews]

When I install gst123 and try to play an mp3 file no sound comes and I
see:

: Error: Your GStreamer installation is missing a plug-in.

This happens both when I use 'guix environment' and from my default
profile. In contrast, mpg123 had no trouble playing the file.

Does adding ‘gst-plugins-bad’ to the profile fix it?  It let me 
play a random .mp3 file[0], but only without --pure.

Kind regards,

I tried adding all the gst packages I could think of to the environment,
but it still did not work. Here is what I ran:

guix environment gst-plugins-base gst-plugins-bad gst-plugins-good gst-plugins-ugly gst123 -- gst123 "/path/to/music-file.mp3"

Error: Your GStreamer installation is missing a plug-in.
=> file cannot be played and will be removed from playlist

Use ‘guix environment --ad-hoc’.  The command above doesn't add 
any of the packages to the environment, only their build 
dependencies.

I forgot about gst-plugins-base, maybe it suffices.

Kind regards,

Thanks for the tip. Unfortunately, I still see the error:

Error: Your GStreamer installation is missing a plug-in.
=> file cannot be played and will be removed from playlist

after running:

guix environment --ad-hoc gst-plugins-base gst-plugins-good
gst-plugins-bad gst-plugins-ugly gst123 -- gst123
~/path/to/music-file.mp3

You also need 'gstreamer' in the environment to get the
GST_PLUGIN_SYSTEM_PATH variable, so that the plugins are actually
found.  A long-standing bug in Guix.  :-/

I still get the error with:

guix environment gstreamer gst-plugins-base gst-plugins-bad gst-plugins-good gst-plugins-ugly gst123 -- gst123 '/path/to/file.mp3'

Following Leo's advice, I also ran:

guix environment strace gstreamer gst-plugins-base gst-plugins-bad
gst-plugins-good gst-plugins-ugly gst123 -- strace -f gst123
'/path/to/file.mp3'

There were 3403 lines of output, which seems bigger than the Debian
pastebin will let me show, so I'm not sure how to share the whole
thing.

However, here is a list of references to the store in the output
produced with:

: cat $STRACEF_OUTPUT | grep -i -o '"/gnu/store/.*"' | uniq

https://paste.debian.net/hidden/14fe8b8b/

The last lines of output from strace -f looked like:

ioctl(1, TCGETS, 0x7ffff8747000)        = -1 ENOTTY (Inappropriate ioctl for device)

Let me know if there is something else I could be looking for.

For now I'm resigned to just using mpg123 for mp3's instead which works
perfectly fine.

Can you attach the output as a file? If it's too big you can compress it
with gzip or xz.

I think you forgot to add '--ad-hoc' here, unless it was a copy-paste error?

You should run the program with `strace -f` to see exactly what file is
missing.

I wonder if it's a problem with alsa-lib:
