Trying to build MLT on CentOs6 #4

toddrimes · 2014-07-13T00:14:49Z

I'm trying to build MLT on CentOs6 -- is it actually possible?

I already had frei0r installed, but the MLT build script kept blowing up on it, so I disabled it in the build script.

Now I'm getting

g++ -DQT_SHARED -I/usr/include/QtCore -I/usr/include/QtGui -I/usr/include/QtXml -I/usr/include/QtSvg -I/usr/include/QtOpenGL  -I../.. -I/root/melted/20140712/include -DARCH_X86_64 -Wall -DPIC   -O2 -pipe -ffast-math -DUSE_MMX -DUSE_SSE -DUSE_SSE2 -g -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fPIC -pthread -DARCH_X86_64 -Wall -DPIC   -O2 -pipe -ffast-math -DUSE_MMX -DUSE_SSE -DUSE_SSE2 -g -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fPIC -pthread -DARCH_X86_64 -Wall -DPIC   -O2 -pipe -ffast-math -DUSE_MMX -DUSE_SSE -DUSE_SSE2 -g -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fPIC -pthread  -DUSE_EXIF  -Wno-deprecated   -c -o consumer_qglsl.o consumer_qglsl.cpp

but when I add

#include <stdlib.h>

into ~/melted/src/mlt/src/modules/qt/common.cpp, the code is overwritten with un-edited code (so losing my edit) and the error happens again.

How can I fix this? I am really anxious to use MLT as it seems to be exactly what I need!

Thank you,
~Todd

If you only want MLT and melt, then use the build-mlt.sh script instead.
To prevent overwriting your source after the first run and fetch stage of the script, edit the top of the script and set ACTION_GET_COMPILE_INSTALL=0 and ACTION_COMPILE_INSTALL=1.

toddrimes · 2014-07-13T01:10:00Z

Thank you, Dan. I made the configuration changes you specified, added the stdlib include in common.cpp, and it seemed to run a bit longer. However, I still got:

...

toddrimes · 2014-07-13T01:30:36Z

Oh, I see build-melt doesn't build rugen...trying that.

toddrimes · 2014-07-13T01:35:56Z

Okay, running build-melt (not meltED), I got past RUGEN. Now I get:

should I run ./configure before trying to run the script?

bmatherly · 2014-07-13T01:56:11Z

Movit is failing to configure. This is totally a guess, but maybe try moving "AC_INIT(movit, git)" to the very top of movit/configure.ac.

Movit is a very new project. So it is quite possible that you are in uncharted territory here.

toddrimes · 2014-07-13T02:05:51Z

Thank you, Brian. That fixed it. Now I'm installing glew, so -- progress!

toddrimes · 2014-07-13T02:20:46Z

Well, not so fast! Back to my original issue:

Any suggestions greatly appreciated!

Oh duh, somehow I reverted back to /root/melted, not /root/melt...

but... same issue:

Aha!

I needed TWO new includes in '/root/melt/src/mlt/src/modules/qt/common.cpp':

#include <string.h>
#include <cstdlib>

Now I got:

Thank you for your help!

bmatherly · 2014-07-13T03:35:18Z

I would have expected "#include <stdlib.h>" to do it.
I'm glad you got it to work.

toddrimes · 2014-07-13T03:47:54Z

Thank you.

But... I don't know what to do next.

Following the instructions at : http://www.mltframework.org/bin/view/MLT/BuildScripts

Run the build
Then, run start-melted-server ** can't find this, ***. Wait a couple of seconds to let the server start. Next, run start-melted-client. ** or this, ***

Configure the runtime environment
Edit etc/start-melted.conf to set the MLT profile to use. ** or this **

SO close! Thanks again--
~Todd

toddrimes · 2014-07-13T04:05:58Z

Ok - sorry I think I get it. I only installed the framework, not the application. Will this still get me to where I can run(??) :

melt https://archive.org/download/IMB_SF_R35_C8/IMB_SF_R35_C8_512kb.mp4 in=400 \
    -track https://archive.org/download/IMB_SF_R19_C9/IMB_SF_R19_C9_512kb.mp4 in=450 \
    -filter chroma key=0x00ff0000 variance=0.45 \
    -transition composite

That's what I'm after... I'll try it -- sorry for the floundering...

Thank you,
~Todd

toddrimes · 2014-07-13T04:43:42Z

Ugh - this is not great. I already had ffmpeg installed and working but I guess melt installed its own version of it, creating a new default path to its ffmpeg, for which my web server no longer has execute permission. If I uninstall MLT will my previous ffmpeg be reinstated? It took me weeks to get that working. Help!

bmatherly · 2014-07-13T05:40:16Z

The script doesn't install anything on your system and it doesn't change any system paths. It just builds the binaries and puts them all in the directory specified by the script. In your case, that looks to be "/root/melt/20140713". In that folder, you should look for a script called "melt" which wraps the compiled melt with additional shell variables to make it work. You can call that "melt" script as if it were the melt binary and it will pass the arguments along to the real melt binary.

toddrimes · 2014-07-13T06:21:38Z

Awesome! I figured that out when I accidentally blew away my whole melt
install! So I'm starting over, though I don't expect the do-over to be
hard at all. If I comment out the FFMPEG config lines at the top of the
build script, will melt work with my already-installed ffmpeg
(/usr/local/bin/ffmpeg), which I already have working with my web server?
I'm trying that -- in the morning. Good night and thanks so much for
your help!

No, the script does not support using the system-installed FFmpeg as that entirely defeats the purpose of the script. Build without using the script if you want that.

ddennedy · 2014-07-13T18:33:10Z

Added missing cstdlib include in MLT git commit 4035fc1. I did not add cstring because it is not needed in qt/common.cpp. The dependency might be elsewhere.

toddrimes · 2014-07-13T18:34:21Z

Thank you, Dan. I just added absolute paths to my PHP scripts so the web app uses the 'system' FFmpeg but MLT uses its own -- seems to work. Thank you for the help!
