Remove support for libswresample as we have libavresample

[rgonnering]

I've installed all of the dependencies that I can uncover, and when I do:
$ ./waf configure --mode=release --with-python --with-examples --with-vamp --with-cpptest

I get:

But when I do:

I get a bunch of errors. Some are below and all seem to bee related:

Can anyone help? I am using Ubuntu 14.04.

[dbogdanov]

There were some compatibility issues with Ubuntu 14.04 that were fixed in the 2.0.1 branch. It is written in the notes for the 2.0.1 release.

You can install from that branch, but for more updates use 2.1_beta2 release instead.

[rgonnering]

Thanks for your help.
2.01 is the branch I am using, and is the one with the reported problems.
I'll try 2.1 beta2.

[rgonnering]

I tried 2.1 beta 2. The results are the same as before.

$ ./waf configure --mode=release --with-python --with-examples --with-vamp --with-cpptests
Again, shows that everything is present.

$ ./waf
Again, fails the same way:

[rgonnering]

I have now tried essentia-master.

With $ ./waf configure --mode=release --with-python --with-examples --with-vamp --with-cpptests
Now there is a new dependency and it says not found

but it is installed:

Now when I do $./waf

[dbogdanov]

What is the version of libavformat/livavcodec/libavutil packages? You can check that in build/config.logfile.
For building from master branch you will need more recent LibAv packages from Ubuntu 14.10.

[rgonnering]

Hi,

[rgonnering]

Does anyone have any ideas on how to proceed. Essentia still doesn't build.

[dbogdanov]

You are missing another library, if you are building the master branch or 2.1beta2. Install libavresample-dev package.

I've checked the code and there is an error in the case libswresample is detected. Libavresample is a replacement for this library and we would probably get rid of supporting libswresample.

Thank you for your report!

[rgonnering]

Thanks again for responding. I already have libavresample-dev installed.

$ sudo apt-get install libavresample-dev

Sorry, try again.

Should I get rid of libavresample or libswresample?

Thanks, again.

[dbogdanov]

Remove the libswresample

[dbogdanov]

Btw, if you are building master branch, and you have libavresample installed and detected by Essentia (check in log), the error should not appear.

[rgonnering]

We might get this yet.

I removed libswresample. (Actually, I did
$ sudo mv /usr/local/lib/pkgconfig/libswresample.pc /usr/local/lib/pkgconfig/libswresample.pc.sav
so libswresample couldn't be found.)

I also downloaded and extracted essentia-2.1_beta2 for this go.

$ ./waf configure --mode=release --with-python --with-examples --with-vamp --with-cpptests
now shows:
Checking for 'libavcodec' >= 53.25.0 : not found
Checking for 'libavformat' : not found

'configure' finished successfully (0.448s)

$ sudo ./waf install

SUCCESS!

Dmitry, YOU ARE THE MAN!

Thank you for all of your help. I'll share this success. Thanks, again.

[dbogdanov]

It is strange however, that is reports you that

Checking for 'libavcodec' >= 53.25.0 : not found
Checking for 'libavformat' : not found 

Before you did not have this problem, according to your log copy-paste.
We'll keep this ticket open until the libswresample issue is fixed.

[rgonnering]

Dimitry,
Back when my essentia adventure started, "Checking for 'libavcodec' >= 53.25.0 : not found" was an indicator the ffmpeg was missing. It is beyond me, especially since
$ whereis libavcodec
libavcodec: /usr/local/lib/libavcodec.a /usr/include/libavcodec

This shows that libavcodec is installed.

At any rate, I really appreciate all of the help you provided.

Thanks,
Roger

[dbogdanov]

Check the config.logagain. Before it was reporting that 57.15.100version was detected

Just to add to the confusion a bit, I also have a Windows computer with VirturalBox and a Ubuntu 14.04 Guest OS.

I ran all of the same steps, except with --with-gaia
./waf configure --mode=release --with-python --with-examples --with-vamp --with-cpptests
I built, and I was able to import essentia into ipython, but I got this:

This is different.

[dbogdanov]

You got some mess with your libav installation. In your case libavcodec depends on libswresample and this is probably because you've built libav/ffmpeg from source.

Your libav is installed in /usr/local/lib. Remove all that installation and start from scratch. If you are ok with that, the best way would be to use apt-get:

sudo apt-get install libavcodec-dev libavformat-dev libavutil-dev libavresample-dev

[rgonnering]

Dimitry,

As I understand it, ffmpeg is needed and the only way to get it is to build
it on Ubuntu 14.04. Please let me know if there is another way.

Thanks,
Roger

No, only some parts of ffmpeg are required, and that are present in Ubuntu. You can install all required packages via apt-get as suggested in documentation:

sudo apt-get install libavcodec-dev libavformat-dev libavutil-dev libavresample-dev

[dbogdanov]

I have fixed the issue with libswresample. You can restore the pc file from /usr/local/lib/pkgconfig/libswresample.pc.sav and check if it works.

[rgonnering]

I originally did that, only to find that I needed to install ffmpeg.

OK. I'll try. I assume I have to start over, by downloading the source then
run through the steps.

Did I do something wrong or miss a step?

Additionally, I forgot to add, from build/config.log:

Checking for 'libavresample'
['/usr/bin/pkg-config', '--cflags', '--libs', '--modversion', 'libavresample']
err: Package 'libavresample' requires 'libavutil = 52.3.0' but version of libavutil is 54.31.100
not found

from /home/roger/github/essentia/src: The configuration failed

$ whereis libavresample
libavresample: /usr/include/libavresample

[dbogdanov]

Still there is a mess. Remove everything libav* related from /usr/local
It is where Essentia configure script first looks for libraries. And this produces all the mess.

If you are on Ubuntu 14.04 - use Essentia 2.1beta2.

[rgonnering]

Should I

$ sudo apt-get remove libav-tools

or

$ cd /usr/lib
$ rm -r libav*

Remove libav* files from folders:

• /usr/local/include/
• /usr/local/lib/
• /usr/local/lib/pkgconfig/

[rgonnering]

Dimitry,
I'm happy, and I'm sure you'll be happy because I will no longer need to bother you. Your fix worked.

Get rid of libav*
$ cd /usr/local/include
$ sudo rm -r libav*
$ cd ../lib
$ sudo rm libav*
$ cd pkgconfig/
$ sudo rm libav*

I downloaded and extracted Essentia 2.1beta2 to $HOME/essentia-2.1_beta2.

$ sudo apt-get install build-essential libyaml-dev libfftw3-dev libavcodec-dev libavformat-dev libavutil-dev libavresample-dev python-dev libsamplerate0-dev libtag1-dev

I had previously done this
$ sudo apt-get install python-numpy-dev python-numpy
$ sudo apt-get install python-pip
$ pip install pyyaml

libswresample is present:
$ ls /usr/local/lib/pkgconfig
essentia.pc fdk-aac.pc gaia2.pc libswresample.pc libswscale.pc vpx.pc

$ cd essentia-2.1_beta2/
$ ./waf configure --mode=release --with-python --with-examples --with-vamp --with-cpptests --with-gaia

Here's the message:

$ ipython

run centroid <--------- this works!!!!!!!!

Again, Dmitry, thank you for all of your help.
