gstreamer-bad-plugin: removesilence runtime link error

[Sagar]

hi,

I built the .so file but following steps provided on github page for gstreamer-bad-plugin but I am getting this error Failed to load plugin '/usr/lib/x86_64-linux-gnu/gstreamer-1.5/libremovesilence.so': /usr/lib/x86_64-linux-gnu/gstreamer-1.5/libremovesilence.so: undefined symbol: gst_base_transform_get_type

also I am not able to gst-inspect on removesilence. I understand there are some CFLAGS missing but where it is missing I am not able to figure out. can you please help

Which steps provided on which GitHub page? You're probably using
Kurento's GStreamer fork here, not the official one.

Check with ldd if libgstremovesilence.so is linked to libgstbase-
1.5.so.0. It is in the official GStreamer version but it was since the
very beginning, so not sure what the problem here could be.

using ldd command gives libgstbase-1.5.so.0 => /usr/lib/x86_64-linux-gnu/libgstbase-1.5.so.0 (0x00007f427df45000)

and sorry for not mentioning, I am using https://github.com/Kurento/gst-plugins-bad fork

Is ldd showing some missing dependency?

Here is the mine for reference

I don't know what solved the issue but I did two changes

1. added GST_BASE_LIBS = -lgstbase-1.5
2. installed gstreamer1.5-tools

now its working fine.

ldd libgstremovesilence.so

@Nicola : I have a question related to vad-private.c

#define VAD_POWER_THRESHOLD 0x000010C7  /* -60 dB (square wave) */

I want to change -60 to -40 but I 0x000010C7 is not an hex value, can you please tell what type of value it is? what will be the equivalent value of -40db ?

-40db should be 0x00068DB9 (untested)

let me know if it works as expected,

how do you calculate it ? is there any specific formula/method ?
I thought in 0x000010C7  C7 will be 2's compliment of -60. and -40's 2's compliment will be DF meanwhile I will test the value which you gave.

[Sagar]

https://it.wikipedia.org/wiki/Decibel
-60Db = 0.000001
4294967296 * 0.000001 = 4295 or 0x000010C7 hex
-40Db = 0.0001 using the formula above you should have 0x00068DB9,
please confirm that this value give you the expected results,

-Nicola

0x00068DB9  Worked for me thanks...

[Mailing List SVR]

OK, thanks for confirming, after the actual pending modifications are
merged to master maybe I can do another patch to make this threshold
configurable with a property,
