• Ffmpeg error in Docker Container : ffmpeg exited with code 1 :

  2 octobre 2017, par Uğur Kaya

  I am currently working on a project and almost ready to deploy, but there is one problem : the code which is working perfectly on my Ubuntu 16.04 (Elementary OS Loki) machine does not work in Docker container. What might be the problem in my code ?

  Here is my Dockerfile :

  FROM beevelop/nodejs-python:latest
  
  
  
  RUN apt-get -y update && apt-get install -y libav-tools
  
  RUN ffmpeg --help
  
  
  
  # Global install yarn package manager
  
  RUN apt-get update && apt-get install -y curl apt-transport-https && \
  
      curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - && \
  
      echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list && \
  
      apt-get update && apt-get install -y yarn
  
  
  
  WORKDIR /app
  
  COPY package.json .
  
  RUN yarn
  
  COPY . .
  
  RUN yarn prod:build
  
  EXPOSE 8080
  
  CMD [ "yarn", "start" ]

  I run sudo docker exec -it  ffmpeg --help and it outputs the expected help print. In my code, I download a Youtube video in mp4 format with this code :

  const download = idParam => (
  
    new Promise((fulfill, reject) => {
  
      const id = `http://www.youtube.com/watch?v=${idParam}`
  
      let videoMeta
  
      youtubedl(id, ['--format=36'], { cwd: __dirname })
  
        .on('info', (info) => {
  
          const customDimensions = calculateCustomDimensions(info.format)
  
          videoMeta = { ...info, ...customDimensions }
  
        })
  
        .pipe(fs.createWriteStream(`temp/${idParam}.mp4`))
  
        .on('finish', () => {
  
          console.log('Dirname: ', __dirname)
  
          fulfill(videoMeta)
  
        })
  
        .on('error', (err) => {
  
          console.log('There is an error:', err)
  
          console.log('Dirname: ', __dirname)
  
          reject(err)
  
        })
  
    })
  
  )

  And then try to process the video with fluent-ffmpeg :

  const processVideo = (videoName, cropStart, cropEnd) => (
  
    new Promise((resolve, reject) => {
  
      try {
  
        console.log('Trying to run ffmpeg binary.')
  
        ffmpeg()
  
          .addInput(`temp/${videoName}.mp4`)
  
          .seekInput(cropStart)
  
          .duration(cropEnd)
  
          .outputOption('-movflags frag_keyframe+faststart')
  
          .on('end', () => {
  
            console.log('Processing has finished with ffmpeg. ')
  
            console.log('Resolved for upload: ', [`temp/cropped_${videoName}.mp4`, `temp/${videoName}.mp4`])
  
            console.log('Going out of processVideo script.')
  
            resolve([`temp/cropped_${videoName}.mp4`, `temp/${videoName}.mp4`])
  
          })
  
          .on('error', (err, stdout, stderr) => {
  
            console.log('Error. Output option olmasına rağmen: ', err.message)
  
            console.log('ffmpeg output:\n', stdout)
  
            console.log('ffmpeg stderr:\n', stderr)
  
          })
  
          .save(`temp/cropped_${videoName}.mp4`)
  
      } catch (e) {
  
        console.log('There has been an error while converting ffmpeg binary!')
  
        console.log(e.msg)
  
        console.log(e.code)
  
        reject(e)
  
      }
  
    })
  
  )

  It gives the following error :

  Entering download script.

• can't stream rtsp with ffmpeg

  7 novembre 2017, par xswxw222

  I want to stream rtsp with ffmpeg and ffserver

  I use on this config

  <feed>
  
  
  
  
  
  File /tmp/feed1.ffm
  
  FileMaxSize 200K
  
  
  
  # You could specify
  
  # ReadOnlyFile /saved/specialvideo.ffm
  
  # This marks the file as readonly and it will not be deleted or updated.
  
  
  
  # Specify launch in order to start ffmpeg automatically.
  
  # First ffmpeg must be defined with an appropriate path if needed,
  
  # after that options can follow, but avoid adding the http:// field
  
  #Launch ffmpeg
  
  
  
  # Only allow connections from localhost to the feed.
  
  ACL allow 127.0.0.1
  
  
  
  </feed>
  
  #<stream>
  
  #Format rtp
  
  #Feed feed1.ffm
  
  #VideoCodec libx264
  
  #VideoFrameRate 24
  
  #VideoBitRate 100
  
  #VideoSize 480x272
  
  #AVPresetVideo default
  
  #AVPresetVideo baseline
  
  #AVOptionVideo flags +global_header
  
  #
  
  #AudioCodec libfaac
  
  #AudioBitRate 32
  
  #AudioChannels 2
  
  #AudioSampleRate 22050
  
  #AVOptionAudio flags +global_header
  
  #</stream>

  and run ffserver.
  Now i run the ffmpeg like ffmpeg -i input.mp4 http://x.x.x.x:8090/out.h264.

  When i tried to watch on this url with ffplayer i got 2 error :

  1 : On ffplay terminal I see stream ends prematurely al 0 should be (SOME NUMBER) .

  2 : On ffserver terminal I see max packet size 0 too low   Error writing output header for stream live.h264

  I tried to add -packetsize 9999 but it stil show me those errors

  What can I do to fix that ?

• Ffmpeg stream rtsp via h264 with low quality

  9 novembre 2017, par dscsdc

  When i stream rtsp with ffmpeg via upd i got lot of errors of error while decoding MB 48 31, bytestream. and i see the video with low quality.

  I stream with ffmpeg according to this command :ffmpeg -i rtsp://x.x.x.x/... http://y.y.y.y:zzzz

  On this way I send the data to ffserver and then I can watch the video via ffplay or vlc according to url :rtsp://w.w.w.w:(port)/live.h264
  (I have ffserve conf that stream to h264 file).

  When i stream via rtsp tcp all is fine, and i see the video well. but when i stream with rtsp udp i got video with very low quality, freezes or gets stuck.

  I want to understand 2 stuff :

  1. I know that udp is less reliability then tcp, but when i watch on stream from another streaming via rtsp udp i see the video with much more quality.
     is ffmpeg has a problem to stream udp or is that because i stream h264 with rtsp udp.
     What can i do to improve performance of ffmpeg with rtsp udp ?

  2. What does it matter witch type of file i stream (on rtsp udp) if this will be h264 or avi or mp4 or ffm or amp ?
     i see lot of streaming that stream amp , and another that streaming h264
