Gstreamer Kaldi plugin is blacklisted #67

Open alerenato opened 6 years ago

alerenato commented 6 years ago

Hello, I installed the last version of Gstreamer (1.14) on Ubuntu 17.10 with apt-get install. Gstreamer doesn't recognize the plugin because is on the blacklist. The offset of gst-inspect-1.0 command is: /*** Plugin Details: Name libgstkaldionline2.so Description Plugin for blacklisted file Filename ./libgstkaldionline2.so Version 0.0.0 License BLACKLIST Source module BLACKLIST Binary package BLACKLIST Origin URL BLACKLIST

0 features: ****/ There are several problems related to the blacklist. I do not know if the problems mentioned above are the cause or there may be others. Thanks in advance.

in gstreamer 1.14, name of the built .so library should match plugin name since symlinks are extracted automatically

in this case, it should be called libgstkaldinnet2onlinedecoder.so

this unmerged pull request fixes it https://github.com/alumae/gst-kaldi-nnet2-online/pull/65

FYI, you can debug these kinda problems as follows

GST_DEBUG=5 gst-inspect-1.0 ./libgstkaldionline2.so

and the output will tell you that it can't find plugin entry point
