installing yasm / nasm on heroku with vulcan
21 novembre 2013, par scientifficI'm trying to do a build of ffmpeg on Heroku, and I need to use libvpx. In order to install libvpx, I need to have nasm or yasm. I tried installing both using vulcan, but I keep getting the error Neither yasm not nasm has been found
Here is what I did
Installing Nasm
- get nasm source from http://www.linuxfromscratch.org/blfs/view/svn/general/NASM.html
- tar file using : tar -xJf nasm-2.10.09.tar.xz
- build using : vulcan build -v -s . -c "./configure -prefix=/app/vendor/nasm && make && make install"
- add the output of the tar file from vulcan to vendor/nasm
- push to heroku
Installing Yasm
- get yasm source from http://www.linuxfromscratch.org/blfs/view/svn/general/yasm.html
- extra tar file and build using : vulcan build -v -s . -c "./configure -prefix=/app/vendor/yasm && make && make install"
- add the output of the tar file from vulcan to vendor/yasm
- push to heroku
Installing Libvpx
- get libvpx source from http://www.linuxfromscratch.org/blfs/view/svn/multimedia/libvpx.html
- build libvpx using : vulcan build -v -s . -c "./configure —enable-shared —disable-static —prefix=/app/vendor/llibvpx && make && make install"
Attemping to build libvpx yields this error :
Packaging local directory... /.rvm/gems/ruby-1.9.2-p320/gems/vulcan-0.8.2/lib/vulcan/cli.rb:49: warning: Insecure world writable dir /usr/local in PATH, mode 040777
done
Uploading source package... done

**Neither yasm nor nasm have been found**
Configuration failed. This could reflect a misconfiguration of your
toolchains, improper options selected, or another problem. If you
don't see any useful error messages above, the next step is to look
at the configure error log file (config.err) to determine what
configure was trying to do when it died.How can I successfully build libvpx on heroku using vulcan ?
The instructions I've been (loosely) following are from here :
https://gist.github.com/czivko/4392472
And the reason I need to use libvpx is that I'm using the carrierwave-video gem in my Rails app to convert videos, and it needs libvpx to convert to webm to support video playback in Firefox.

libopenjpeg encoding with ffmpeg
21 décembre 2012, par stibThe libopenjpeg codec for ffmpeg is deemed experimental. Does anyone know if it is useable for storage of archival video material, i.e. if I write a whole bunch of video files with it, am I likely top be able to open them in the future ?
Is there any other Free/OSS alternative to using ffmpeg for encoding motionJpeg2000, or for archiving video in general ?
