  • Drawtext, drawbox or overlay on only a single frame using FFmpeg

    10 juillet 2013, par waxical

    I'm using the drawtext and drawbox avfilters on FFmpeg, two of the most poorly documented functions known to man.

    I'm struggling to work out if and how I can use them on only a single frame, i.e., drawtext on frame 22.

    Current command :

    ffmpeg -i test.wmv -y -b 800k -f flv -vcodec libx264 -vpre default -s 768x432 \
    
  -g 250 -vf drawtext="fontfile=/home/Cyberbit.ttf:fontsize=24:text=testical:\
    
  fontcolor=green:x=100:y=200" -qscale 8 -acodec libfaac -sn -vstats out.flv

    Two elements mentioned in the documentation are n and t. However, I only seem to be able to use them in x and y. Not in text or even as other parameters.

    Any help or FFmpeg guidance would be gratefully received.

  • FFMPEG for Android - missing alsa format

    24 août 2012, par user1545779

    @rowntreerob has an android-ffmpeg implementation that build successfully using the default file settings.

    When you remove disble-avdevice and disbale-devices from the configure_ffmpeg script, ndk-build fails. The following is the error message :

    CP ffmpeg

    collect2 : ld returned 1 exit status

    make : ** [/home/jasongipsyblues/android-ffmpeg/Project/obj/local/armeabi-v7a/ffmpeg] >Error 1

    Please pardon my poor formating skills, I still dont get the formating thing. It appears the deletion of the references is to avdevices is definitely affecting the use of ndk-build.

    All the alsa source files exist in the ffmpeg code. How does one build ffmpeg in such a way that alsa is included in the formats ?
