반송파 설정 content_type이 잘못되었습니다

내 Rails 앱에서 안개가있는 Carrierwave를 사용하고 있으며 Carrierwave-Video 및 Carrierwave-Video-Thumbnailer 보석을 사용하여 업로드 한 동영상에서 동영상 업로드 및 미리보기 이미지 만들기를 사용하고 있습니다.반송파 설정 content_type이 잘못되었습니다

mp4 파일을 업로드 할 때 mp4 파일로 변환하여 mp4로 만들고 webm 버전을 만들고 두 가지 다른 크기의 미리보기 이미지 (.png)를 만들 것을 기대합니다. 현재 모든 파일이 Amazon S3에 성공적으로 업로드되지만 컨텐츠 유형은 모든 파일에 대해 비디오/퀵타임으로 처리됩니다. 이것은 HTML 5 Video 태그를 사용하여 Firefox에서 webm 파일을 재생하려고하기 때문에 문제가되는데 비디오의 콘텐츠 유형이 video/webm이 아닌 video/quicktime으로 설정되어 있기 때문에 재생할 수 없습니다.

이 내 업 로더 파일, 나는 비디오가 업로드 될 때

수동으로 콘텐츠 유형을 설정하는 방법을 찾았 으면 내 대답을 업데이트하는 것을 잊어 버렸습니다. 이것이 내가 끝내었던 것입니다.

require 'carrierwave/processing/mime_types' 
class VideoPathUploader < CarrierWave::Uploader::Base 
    include CarrierWave::MimeTypes 
    process :encode 

    def encode 
    video = MiniExiftool.new(@file.path) 
    orientation = video.rotation 
    model.rotation = orientation 
    Rails.logger.debug("orientation: #{orientation}") 
    Rails.logger.debug("video wxh #{video.imagewidth} #{video.imageheight}") 

    if orientation == 90 && video.imagewidth.to_f > video.imageheight.to_f 
     Rails.logger.debug("rotating video") 
     aspect_ratio = video.imageheight.to_f/video.imagewidth.to_f 
     encode_video(:mp4, custom: "-vf transpose=1", resolution: :same, aspect: aspect_ratio) 
    else 
     aspect_ratio = video.imagewidth.to_f/video.imageheight.to_f 
     encode_video(:mp4, resolution: :same, aspect: aspect_ratio) 
    end 

    instance_variable_set(:@content_type, "video/mp4") 
    :set_content_type_mp4 
    end 

    version :webm do 
    process :encode_video => [:webm] 
    process :set_content_type_webm 
    def full_filename(for_file) 
     "#{File.basename(for_file, File.extname(for_file))}.webm" 
    end 
    end 

def set_content_type_mp4(*args) 
    Rails.logger.debug "#{file.content_type}" 
    self.file.instance_variable_set(:@content_type, "video/mp4") 
    end 

    def set_content_type_webm(*args) 
    Rails.logger.debug "#{file.content_type}" 
    self.file.instance_variable_set(:@content_type, "video/webm") 
    end 
end

희망이 있습니다.

나를 도왔습니다. 감사! – moritz

야심을 느끼는 경우,이 버전에서 작동하지 못하도록 캐리어 웨이브 자체의 버그로 격리 할 수 있습니다.

빠른 검토에서 은 full_filename 대신에 the base file's original_filename을 사용합니다. that's 값 set_content_type은 s3으로 전송 된 콘텐츠 유형을 조회하는 데 사용됩니다.
