How do I get videos to upload using ruby on rails carrierwave-video ?
9 juillet 2016, par EricUpdated as of July 9, 2016
I tried to follow the instructions on the github website for the video uploader process using carrierwave-video gem but get an error that says the file or directory mmpeg -i doesn’t exist.
The upload path for images functions correctly, just not the video one.
I have added all of the following code necessary to help solve the error and minified as much as i possibly could.
Video uploader code using carrierwave
class VideoUploader < CarrierWave::Uploader::Base
include CarrierWave::Video
storage :file
version :mp4 do
process :encode_video => [:mp4, resolution: "100x100"]
end
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
endHere is the movie controller code that handles uploading of videos
class MoviesController < ApplicationController
include MoviesHelper
def index
mode "index"
end
def show
mode "show"
end
def new
mode "new"
end
def edit
mode "edit"
end
def create
mode "create"

def update
mode "update"
end
def destroy
mode "destroy"
end
def review
mode "review"
end
def approve
mode "approve"
end
def deny
mode "deny"

endHere is the model data for the movie that goes with it

ffmpeg : How to get list of available codecs with PHP ?
9 août 2013, par IIIOXIIIProblem is, I am trying to convert (through php), a .3gp (or any video format) file to ogg.
When I do not specify -vcodec and -acodec, the video is converted, but does not have any audio.
I had read here and other places that I need to specify -acodec libvorbis, however, when I specify the codec as libvorbis, the conversion fails : video converts to 0byte file.
Basically, I am trying to determine if the codec specified is actually part of the ffmpeg build I am using as a process of narrowing down my issue.
Code that produces full length video without sound :
$srcFile = 'anyvideo.3gp';
$destFile = 'anyvideo.ogg';
$ffmpegPath = 'path/to/ffmpeg.exe';
$ffmpegObj = new ffmpeg_movie($srcFile);
$srcWidth = makeMultipleTwo($ffmpegObj->getFrameWidth());
$srcHeight = makeMultipleTwo($ffmpegObj->getFrameHeight());
$srcFPS = $ffmpegObj->getFrameRate();
$srcAB = intval($ffmpegObj->getAudioBitRate()/1000);
$srcAR = $ffmpegObj->getAudioSampleRate();
$srcLen = $ffmpegObj->getDuration();
exec($ffmpegPath." -i ".$srcFile." -ar ".$srcAR." -s ".$srcWidth."x".$srcHeight." ". $destFile);And the code that produces 0byte file :
exec($ffmpegPath." -i ".$srcFile." -acodec libvorbis -ar ".$srcAR." -s ".$srcWidth."x".$srcHeight." ".$destFile);
So, my question is, how do I determine the codec's available to ffmpeg using PHP ? Can it even be done ?
