• ffmpeg not working with filenames that have whitespace

  1er avril 2017, par cmw

  I’m using FFMPEG to measure the duration of videos stored in an Amazon S3 Bucket.

  I’ve read the FFMPEG docs, and they explicitly state that all whitespace and special characters need to be escaped, in order for FFMPEG to handle them properly :

  See docs 2.1 and 2.1.1 : https://ffmpeg.org/ffmpeg-utils.html

  However, when dealing with files whose filenames contain whitespace, ffmpeg fails to render a result.

  I’ve tried the following, with no success

  ffmpeg -i "http://s3.mybucketname.com/videos/my\ video\ file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d
  
  ffmpeg -i "http://s3.mybucketname.com/videos/my video file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d
  
  ffmpeg -i "http://s3.mybucketname.com/videos/my'\' video'\' file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d
  
  ffmpeg -i "http://s3.mybucketname.com/videos/my\ video\ file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d

  However, if I strip out the whitespace in the filename – all is well, and the duration of the video is returned.

  Any help is appreciated !

• Text on video using FFMPEG

  22 novembre 2017, par Rao

  i am trying to add text on a video using ffmpeg. I have seen so-many helps in stackoverflow and followed, but hard luck i couldn’t succeed.

  i have followed this thread.

  Here is my command

  ffmpeg -i C:/source/TestScene.mov -vf drawtext="fontfile=c:/windows/fonts/arial.ttf: text='TestMessage': fontcolor=white: fontsize=24: box=1: boxcolor=black@0.5: boxborderw=5: x=(w-text_w)/2: y=(h-text_h)/2" -codec:a copy C:/source/TestScene_test.mov

  Here is my error traceback

  F:\SW\ffmpeg\bin>ffmpeg -i C:/source/TestScene.mov -vf drawtext="fontfile=c:/windows/fonts/arial.ttf: text='TestMessage': fontcolor=white: fontsize=24: box=1: boxcolor=black@0.5: boxborderw=5: x=(w-text_w)/2: y=(h-text_h)/2" -codec:a copy C:/source/TestScene_test.mov

• avcodec/mpegvideo : Only keep the actually used unquantize funcs

  19 mars, par Andreas Rheinhardt

  avcodec/mpegvideo : Only keep the actually used unquantize funcs
  For all encoders and all decoders except MPEG-4 the unquantize
  
  functions to use don't change at all and therefore needn't be
  
  kept in the context. So discard them after setting them ;
  
  for MPEG-4, the functions get assigned on a per-frame basis.
  Decoders not using any unquantize functions (H.261, MPEG-1/2)
  
  as well as decoders that only call ff_mpv_reconstruct_mb()
  
  through error resilience (RV30/40, the VC-1 family) don't have
  
  the remaining pointers set at all.
