PE 1.4.2

ValueError: max() arg is an empty sequence Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/PulseEffects/gst.py", line 346, in on_message if max(magnitudes) > -100: ValueError: max() arg is an empty sequence Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/PulseEffects/gst.py", line 346, in on_message ....

and keeps repeating

Hi

I released a new version that should fix this error.

[teamosceola]

I also have no spectrum visualization, but with a different repeating error.

Traceback (most recent call last): File "/home/chris/pulseeffects/PulseEffects/gst.py", line 343, in on_message magnitudes = msg.get_structure().get_value('magnitude') TypeError: unknown type GstValueList ...

This is as of: commit 6fe629e4d5d8100eb29807d80ec5d0b45b267425 Author: wwmm wellington.melo@cefet-rj.br Date: Sun May 28 17:46:55 2017 -0300

updated readme image

This is on Ubuntu 16.04 LTS with Unity

Thanks!

Hi,

Use version 1.4.1 https://github.com/wwmm/pulseeffects/archive/v1.4.1.tar.gz. Higher versions will need gstreamer 1.12. You probably have a lower version in your system. Before Gstreamer 1.12 we needed a hack to get spectrum magnitudes using Python. The type GstValueList was not exposed in gst-python api. Gstreamer developers added the missing types in Gstreamer 1.12

1.4.4 - still the same error BUT

I see that i don't have visuals if i use $ pactl load-module module-echo-cancel and set the default output to that module

If i just switch default back to soundcard it works.

While switched to soundcard:

While switched to echo cancelled soundcard:

I was able to reproduce the problem with module-echo-cancel. Its lower sampling rate(32000 Hz) is triggering this bug. If I have the time I will release a new version fixing this in 1 or 2 days.

I released version 1.4.5. It fixes the problem with module-echo-cancel in my system.
