Description Bernhard Stiftner 2012-12-26 21:53:07 UTC
Some frei0r plugins (most notably cannot be used with kdenlive for rendering a video project. Although effect previews in kdenlive work fine, rendering the project does not - it silently fails, yielding an empty output file.

Kdenlive's rendering process uses melt. Invoking melt on the command line gives a clue about the actual error:
/usr/bin/melt /home/bernhard/kdenlive/scripts/ -profile dv_pal_wide -consumer avformat:/home/bernhard/kdenlive/Unbenannt.mp4 progress=1 f=mp4 acodec=libmp3lame ab=128k ar=44100 vcodec=mpeg4 minrate=0 vb=12000k

/usr/bin/melt: symbol lookup error: /usr/lib64/frei0r-1/ undefined symbol: hypotf

Seems like the rendering process breaks due to undefined symbols (at runtime!) in The undefined symbol is hypotf - should be defined in, but doesn't link against it.

Reproducible: Always

Steps to Reproduce:
1. Start new kdenlive project
2. Import video track
3. Attach Deform -> Defish effect to the video track (previews in kdenlive may work fine)
4. Render the project
Actual Results:  
Kdenlive rendering starts, but stops almost immediately. It doesn't report any error, but the output file is empty.

Expected Results:  
Expected kdenlive to render the file, applying the defish effect from

Quick and dirty patch

Quick and dirty workaround: 
* Force all frei0r plugins to be linked against
* Remove the --as-needed linker option (may also cause problems?)
Comment 2 vylaern 2013-02-01 10:32:02 UTC
I have similar problem with Vertigo effect in Kdenlive from frei0r plugins.

Actual Results:  
Kdenlive rendering starts, but stops almost immediately. It doesn't report any error, but the output file is empty.

I was checking with new mlt-0.8.8 which was released few days ago, but still the same. I will check it with a new Kdenlive o.9.4 which will be in portage soon.
Comment 3 vylaern 2013-05-08 21:10:36 UTC
There is a new version of frei0r - 1.4.0 (not yet in portage, but there is bump request)
hopefully it should solve our problems

1.4.0 - 24 February 2013

	This release fixes several major bugs in existing plugins,
	adds new filters and the optional dependency to cairo.
	New filters (18): IIRblur, Vignette, Keyspillm0pup, Timeout,
	  Posterize, Dither, Spillsupress, Emboss, Colgate, RGBNoise,
	  Colorize, Softglow, ColrHalftone, Sigmoidaltransfer,
	  Colortap, cairogradient, cairoimagegrid, medians
	New mixers: cairoblend, cairoaffineblend

Patch for frei0r-plugins-1.4 to fix underlinking issues

Just tried again with frei0r-plugins-1.4.0, but the problem still persists.
Other frei0r effects are affected as well, it's not defish0r and vertigo, but probably about half of the available frei0r effects.

The problem is still the same: A lot of frei0r plugins include <math.h>, but do not explicitly link against When /usr/bin/melt tries to dlopen() those plugins, math symbols cannot be resolved and /usr/bin/melt dies. That's the reason why kdenlive rendering fails.

I've attached a patch for frei0r-plugins-1.4 which should fix those underlinking issues. Unlike my first quick&dirty patch from Comment #1, this one does not force every frei0r plugin to be linked against, but only adds where it's really necessary. It also doesn't remove the --as-needed linker option anymore.

Using the patched frei0r plugins, kdenlive rendering works again.

Proposal for frei0r-plugins-1.4.1-r1.ebuild

Attached proposal for frei0r-plugins-1.4.1-r1.ebuild which applies the underlinking patch from Comment #4.
Comment 6 Rafal Lalik 2017-09-08 23:29:27 UTC
Problem still exists in 1.5.0. Please add these two lines to src_configure section and problem will be solved (I run it with 1.5.0, didn't test with ~amd64)

    append-ldflags -lm

Comment 7 Pacho Ramos gentoo-dev 2018-03-01 10:50:36 UTC
are you still hitting this with 1.6.1 ?
