It hangs to import with replaygain: gstreamer

Ubuntu 14.04 64 bits

I try to import a mp3 folder with replaygain: gstreamer but beets hangs.

You are using an old version of the GStreamer python bindings. Please upgrade to a version higher than 1.0 (you're using 0.10).

[simonbcn]

I have installed python-gst-1.0 and python-gst0.10. I have uninstalled python-gst0.10 and now it seems work well. I think beets should be select the right gst version automatically.

[yevgenybezman]

The code requires 1.0 and I've had luck running it with 1.0 and 0.1 installed concurrently. Are you sure you had 1.0 installed when it hung?

[sampsyo]

We've seen some hangs when using both versions simultaneously, as can happen when the chroma plugin is also enabled. Could that have been the case here?

[simonbcn]

Yes, I had installed both versions.

[yevgenybezman]

@sampsyo chroma uses acoustid, which in turn uses audioread, which in turn uses gstreamer. Maybe you're not enforcing the correct version in audioread?

Edit: Seems audioread uses the pre-1.0 bindings. I guess they don't like being imported simultaneously.

[sampsyo]

We are enforcing the correct version, but the correct version is (unfortunately) still 0.10 for audioread. See also: https://github.com/sampsyo/audioread/issues/11

[yevgenybezman]

Any reason? (other than lack of time)

[sampsyo]

Nope; just time.

FWIW, I ran into a similar issue while trying to run on Debian testing, where it would hang indefinitely after printing some errors. (This was a little disturbing since the manual warns you to expect the initial import to be very slow so I was unsure if it was broken or just very slow until I googled the error and got here.) Doing a sudo apt-get remove python-gst0.10 got it running again

But I am uncertain if the chroma plugin was working or not during my import. To be safe I ran beet fingerprint; beet submit after I was finished.
