  • 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

    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.
