• 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.
