  • Amazon S3 : how to combine all images into a video ?

    17 mars 2015, par scientiffic

    I’m in my Rails app, I enable users to upload images, which get processed using ffmpeg to create a video slideshow.

    I have this working locally, but am wondering how to do this when deploying the app using Heroku. In particular, I know Heroku has limited storage and has a read-only filesystem, so using Carrierwave without S3 or an external storage option doesn’t seem like an option.

    But how would I run a task like the following using S3, where I combine all images into a video ?

    The ffmpeg command is

    ffmpeg -r 5 -i https://s3.amazonaws.com/[]/uploads/image/image_file/26/img%03d.jpg output.mp4 -y

    And the AWS "folder" contains the following :
    https://s3.amazonaws.com/[]/uploads/image/image_file/26/img001.jpg
    https://s3.amazonaws.com/[]/uploads/image/image_file/26/img002.jpg
    https://s3.amazonaws.com/[]/uploads/image/image_file/26/img003.jpg

    When I try to do the following, I get an error with ffmpeg not knowing what to do with :

    https://s3.amazonaws.com/[]/uploads/image/image_file/26/img%03d.jpg

    Note, this whole video compilation process works fine for me locally, so I know in theory it should work.

  • Intsallation of ffmpeg-php on Amazon Ec2 Linux AMI

    1er décembre 2015, par Tanny

    I am about two days into attempting to install FFMPEG-php with dependencies on an AWS EC2 instance running the Amazon Linux AMI. I’ve installed FFMPEG, and have read reportedly successful instructions on installing on Red Hat/Fedora. I have followed a number of tutorials and forum articles to do so, but have had no luck yet. As far as I can tell, the main problems are as followed :

    I have installed all the dependency for ffmpeg-php. I run the following command successfully.

    $wget http://downloads.sourceforge.net/project/ffmpeg-php/ffmpeg-php/0.6.0/ffmpeg-php-0.6.0.tbz2
    $tar xvfj ffmpeg-php-0.6.0.tbz2
    $phpize

    But when I run the following command it throw the error like below :

    $sudo ./configure

    configure : error : ffmpeg shared libraries not found. Make sure ffmpeg is compiled as shared libraries using the —enable-shared option}

    I have used enable shared option with shared enable option but it throw the same error.

    On to my question : Has anyone successfully installed FFMPEG-php on Amazon Linux ? Is there a fundamental incompatibility ? If anyone could share specific instructions on installing ffmpeg-php on amazon linux I would be greatly appreciative. Any other insights/experiences would also be appreciated.

  • NVIDIA accelerated ffmpeg (nvenc_h264 ) is dead slow on Amazon G2 instance

    16 novembre 2015, par Abhijit Pathak

    FFMPEG when compiled with following options give abysmal performance on Amazon G2 instance( g2.2xlarge, GRID K520) when compared with standalone Dell-Precision-T1700 (Quadro-k620)

    "--enable-nonfree --enable-gpl --enable-version3 --enable-shared --enable pthreads [b]--enable-nvenc[/b] --enable-runtime-cpudetect --disable-doc --enable-libmp3lame"

    Above ffmpeg binary took 66 seconds to transcode 5.22 mins BVE_Localize.mp4 file with following command.

    time ffmpeg -y -i BVE_Localize.mp4 -strict -2 -vcodec nvenc_h264 -b 5000k -acodec aac -ab 256k -f mpegts BVELocalize.ts ( took 1m6.990s on G2)

    When same ffmpeg command is executed on Dell-Precision-T1700 (Xeon Dual core, Quadro K620) based workstation takes 0m41.572s.

    I would like ffmpeg to perform better on Amazon G2 instance. What do you think I might be missing ? My Amazon G2 instance configuration is Ubuntu 14.04 64 bit, Cuda 7.0 , 352.55 drivers, MSI disabled,NVIDIA SDK 5.0.1
