• Error : No such filter : '"movie', what's the isssue ?

  16 mars 2019, par uno

  I am using the code to add watermarks to videos on upload for carrierwave-video :

  process encode_video: [:mp4, resolution: "640x480", watermark: {
  
      path: "app/assets/images/logo-nike.jpg",
  
      position: :bottom_right,
  
      pixels_from_edge: 10
  
    }]

  When i use this code, i get error :

  (in short)

  Stream mapping:
  
    Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264))
  
    Stream #0:1 -> #0:1 (aac (native) -> aac (native))
  
  Press [q] to stop, [?] for help

  Error reinitializing filters!
  
  Failed to inject frame into filter network: Invalid argument
  
  Error while processing the decoded data for stream #0:0
  
  Conversion failed!
  
  ):

  my ffmpeg version is 4.1.1

  Is there something missing from ffmpeg i need to install ? I have looked around and found no issues with others using this code (most posts are years old though)

  I found this : No such filter : ’drawtext’

  but isn’t the same thing ?

• FFMPEG not "decoding" the right url input

  9 mars 2019, par Tayax

  Ok sorry everyone if the title is not very clear. Any idea would be helpful.

  Basically I am trying to save small portions of videos and upload them to my server. The thing is, it seems that somehow the video input url I put is being redirected during the process, and FFmpeg get rid of some of it.

  Explanation with a practical example :

  ffmpeg -ss 5 -i "https://serverigetmyvideofrom.com/videos/xxxxx.mp4" -t 139 -y \
  
  -codec:v libx264 -codec:a libfaac /var/www/vhosts/www/36.mp4 \
  
  > /var/www/vhosts/xxx/block.txt 2>&1 &

  And in the block.txt file, I have this error :

  https://serverigetmyvideofrom.com/videos/x/xxxx/xx.mp4?someparameter%3D: Server returned 401 Unauthorized (authorization failed)

  And so it seems that FFMPEG stopped the url at the caracter " : " but somehow I doubt it’s the end of the url.

  Nonetheless, I would like to know how I can access directly the end url ?

• FFMPEG - concatenating mp4s from different sources - unable to stop "Non-monotonous DTS in output stream" warning

  19 novembre 2018, par Sam P

  I need to concatenate mp4 files from different sources, this means some of the variables are out of my control such as timebase, aspect ratio and encoding. So to get around this I re-encode and attempt to standardise the files before concatenating them. Unfortunately, despite this I get Non-monotonous DTS in output stream warnings during the concatenation stage, and the output video seems to always have broken audio/video syncing by the last segment.

  I know there are a lot of other questions out there about resolving the warning above, but I’ve been through them all and reviewed the documentation.. but unfortunately I’ve been still been unable to solve it..

  I think the thing which I don’t understand is : if I have mp4s from different sources, what exactly do I need to do to ensure that the files will always neatly concatenate together ?

  What I’ve tried so far

  The script I’m using to standardise the mp4 files before concantenation is the following (amends resolution, frame rate, timebase, bitrate for audio, bitrate for video, audio encoding and video encoding) :

  ffmpeg -y -i $1 -vf 'scale=1280:720:force_original_aspect_ratio=1,pad=1280:720:(ow-iw)/2:(oh-ih)/2' -r 30 -video_track_timescale 90000 -b:a 128K -b:v 1200K -c:a aac -c:v libx264 $2

  Here’s the ffprobe output on two of the files, there are some differences but I’m not sure if they are significant ?

  They all have normal video and audio at this point.

  After that I concatenate them and add a watermark using the following (it sucks that I need to re-encode here) :

    ffmpeg -y \
  
      -f concat \
  
      -safe 0 \
  
      -i $INFILES \
  
      -c:v libx264 \
  
      -c:a copy \
  
      -preset fast \
  
      -vf drawtext=enable="'between(t, $DRAW_TEXT_DELAY, $DRAW_TEXT_DURATION)': fontfile=$FONT_DIR/$FONT: text='$TEXT': fontcolor=$FONTCOLOR: fontsize=$FONTSIZE: $POSITION" \
  
      $OUTFILE

  INFILES is a path to a text file formatted like :

  file /usr/src/app/data/test/out/intro.mp4
  
  file /usr/src/app/data/test/out/middle.mp4
  
  file /usr/src/app/data/test/out/outro.mp4

  What am I missing here ? Is there a way to debug this further ?
