• How to configure X264 build before running make on OS X

  18 octobre 2013, par user1884325

  I'm trying to build an X264 executable which will run on any MAC OS X (>10.6) without any external dependencies. I downloaded the latest stable snapshot x264-snapshot-20131017-2245-stable.

  I haven't been able to find a lot of documentation on the build procedure for x264 on OSX.

  When I just run ./configure —disable-opencl and then make, I get several output files :

  x264
  libx264.a
  .depend
  x264.o

  I assume that the executable can run without the other files ?

  Anyway, I tested the x264 in a terminal and at first it seemed to work, but when I try to
  start x264 as a quiet background process like this :

  ./x264 —quiet —profile baseline —level 3.2 —preset ultrafast —bframes 0 —force-cfr —no-mbtree —sync-lookahead 0 —rc-lookahead 0 —intra-refresh —input-csp rgb —fps 15 —input-res 1280x720 —bitrate 1100 —vbv-maxrate 1100 —vbv-bufsize 600 —threads 1 -o - -

  nothing happens at all. If I go to Activity Monitor I should see x264 running, but it's not there.

  Looong story short : How should the x264 build be configured before running make ??? I do not want to use openCL (—disable-opencl)

• ffmpeg Drawtext with timer not working

  8 octobre 2017, par codeul

  ffmpeg Drawtext with timer not working.

  Here’s my CLI code :

  ffmpeg -t 20 -i song.mp3 -i bluebg.jpg   -s "1280*720"  -movflags +faststart    -y vwithaudio.mp4 
  
  
  
  ffmpeg -i vwithaudio.mp4 -vf "drawtext=enable='between(t,1,10)':fontsize=30:fontcolor=white:fontfile=pathtoofontfontfile.ttf: text='Test Text'" -acodec copy -y timerdemo.mp4

  No errors displayed at console.

  However, the text would not appear.

  I noticed that in the first command if I use a mp4 instead of bluebg.jpg, it works. So why cannot I use a background image for the first video so that drawtext timer works ?

  Would appreciate help from experts.

  Thanks in advance.
