I am using carrierwave video thumbnailer for making thumbnail of videos. It is working fot .flv files very well. But not working for .swf, .avi, .mpeg, .mp4 files??

If you take a video from an iPad, and the camera is on the left side, the thumbnail appears upside down.

If the camera is on the right side, it works as intended.

hey,I have known about that if this error happend just because I haven't install ffmpegthumbnailer and to solve this problem just install this lib . But for some reason,I can't install this lib successfuly, such as the version of the server dosen't support this. In that case, how can I try this exception? bellow is what I did,but it dosen't work at all !

version :thumb do
  begin
    process thumbnail: [{format: 'png', quality: 10, size: 90, strip: true, logger:Rails.logger}]
    def full_filename for_file
      png_name for_file
    end
  rescue
    nil
  end
end

Hi, how do I use the generated thumbnail in the view? It doesn't seem to mandate the creation of a new column, so presumably it isn't an attribute of the file, no examples are provided either.

I'm currently having an issue where I receive the message below. I tried to install ffmpegthumbnailer using Ubuntu on Windows 10, but nothing seems to solve the issue, directly.

this is the code in video_uploader ,on uncommenting resize to fill gives undefined method error
Please tell how to customize my thumbnail to particular height and width using this gem.

HI,

When i upload a mp4 video, video and video thumbnail both content types are storing as video/mp4. how can i set vide content type to video/mp4 and thumbnail content type image/png.

Uploder.rb:

version :thumb do
    process thumbnail: [{format: 'png', quality: 10, size: 260, workaround: true, strip: true, logger: Rails.logger}]

    def full_filename for_file
      png_name for_file, version_name
    end
end

def png_name for_file, version_name
    %Q{#{version_name}_#{for_file.chomp(File.extname(for_file))}.png}
end

Not exactly an issue with this gem, but I decided it makes sense to mention it here.

Is there any way to recreate the thumbnail for a video with new parameters without having to upload the video again?

When I try to use the url for the video inside of the show action, it tells me that no location is provided. What is the default URL for the thumb extension? **<%= image_tag(@post.post_video_url(:thumb) %>** doesn't work

In document

size: thumbnail length in pixels (defaults to 128).

My question

Is it possible to keep original size?
For example the video may be 1920x1080,
Can I generate a thumbnail also the same size?(1920x1080)

Thanks

Hello~

Dont know why the thumb is rotated.
I upload the video from my i phone.

Why is that?

Hello,

Thumbnail has incorrect mimetype in case of fog storage. On s3 the picture has, for example, AVI type after all.
Everything works well if storage :file

Version 0.1.4
Rails 4.1
Ruby 2.1.0

Is it possible to use ImageMagick processes like resize_to_limit or resize_to_fill from a created thumbnail? For example, I tried:

version :square_thumb do
process thumbnail: [{format: 'png', quality: 10, size: 105, strip: false, logger: Rails.logger}]
def full_filename for_file
png_name for_file, version_name
end
process resize_to_fill: [105, 105]
end

But I get the error "Wrong number of arguments (1 for 0)"

I have been working on building my video thumbnail but haven't been able to get it working. So I figured I would give your's a shot.

I keep receiving this error and not exactly able to narrow down the issue.

When i am generate thumbnail by using carrier wave thumbnailer, the image generating with left and right film stripe how can i remove this stripes.

note: check

I tried to setup the gem with fog storage to amazon s3 but it does not seem to be working.
There are no errors, the png is uploaded to amazon but when i open it it is a 1 second black video.

When i change the storage to :file it is working fine.
I tried the command itself and it is outputting the png correctly.
I tried replacing current_path with a local directory and the thumbnail is showing up just fine.

Any advise on how to get the thumbnail to upload to amazon correctly?

http://f.cq.tl/T1Rb

version :small_thumb, from_version: :thumb do
process resize_to_fill: [20, 200]
end

it doesn't work with a current version carrierwave
it creates a video file instead of image

When I try running the thumbnailer on my video, I get the error:

Errno::ENOENT: No such file or directory

Here are my logs:

This is what my uploader file looks like:

class VideoPathUploader < CarrierWave::Uploader::Base
include CarrierWave::Video
include CarrierWave::Video::Thumbnailer

process encode_video: [:mp4]

Choose what kind of storage to use for this uploader:

storage :fog

Override the directory where uploaded files will be stored.

This is a sensible default for uploaders that are meant to be mounted:

def store_dir
"#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end

version :thumb do
process thumbnail: [{format: 'png', quality: 10, size: 158, strip: true, logger: Rails.logger}]
def full_filename for_file
png_name for_file, version_name
end
end

def png_name for_file, version_name
%Q{#{version_name}_#{for_file.chomp(File.extname(for_file))}.png}
end

end

Hey there,

I am processing video thumbnails using this:

process thumbnail: [{format: 'jpg', quality: 10, size: 175, seek: '50%', square: true, logger: Rails.logger}]

For some reason unknown to me, it is not adhering to the seek. Any chance for some assistance?

I'm trying to create a thumbnail 3 seconds into a mp4 video I've transcoded.

Running....ffmpegthumbnailer -c jpg -q 10 -s 175 -t 00:00:03.0 -a -i /<FILEPATH>/thumb_20160816182847.MP4 -o /<FILEPATH>/tmpfile.jpg

The thumbnail is still showing second 0...what am I doing incorrectly?

The command is successful.

I am having issues running the thumbnailer on Heroku. Everything seems to work fine locally.

The error I receive is:

ffmpegthumbnailer: error while loading shared libraries: libjpeg.so.62: cannot open shared object file: NO such file or directory
Errno::ENOENT: No such file or directory @ sys_fail2 - (/app/public/uploads/tmp/1441312607-10-0856/tmpfile.png, /app/public/uploads/tmp/1441312607-10-0856/thumb_2015-06-02_17.43.37.mp4)

Any idea what might be causing this?

*Note: This happened after upgrading to cedar-14; the thumbnailer worked fine on cedar-10
