  10 septembre 2016, par TNTWap WapChat

  FFMPEG is not working in exec but its working when using ssh on that us
  but other commands work with exec !

  Here is the code :

  exec("ffmpeg -i /home/setare/public_html/kanalmanager/wt/230307754.mp4 -i /home/setare/public_html/kanalmanager/wt/230307754_logo.png \
  
   -filter_complex  "[1]colorchannelmixer=aa=1,scale=iw*1.4:-1[wm];[0][wm]overlay=x=(W-w)/2:y=(H-h)/2" /home/setare/public_html/kanalmanager/wt/230307754_send.mp4 -y");

• How to compile ffmpeg with x11grab ? xlib missing

  12 décembre 2015, par Shuman

  I am compiling ffmpeg on centos 7.1 x64. The error message I got is

  #### FFmpeg static build, by STVS SA ####
  
  *** Building FFmpeg ***
  
  ERROR: Xlib not found

  config.log

  but I have yum installed libxcb, what could be the reason for this ?

  $ rpm -qa | grep libxcb

  edit : it turns out that it’s because I’m not using the correct configure commandline, after following this guide, it works now

  CFLAGS="-I$TARGET_DIR/include" LDFLAGS="-L$TARGET_DIR/lib" ./configure --prefix=${OUTPUT_DIR:-$TARGET_DIR} --extra-cflags="-I$TARGET_DIR/include" --extra-ldflags="-L$TARGET_DIR/lib"  --pkg-config-flags="--static" --enable-gpl --enable-nonfree --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-librtmp

  in which, $TARGET_DIR is where all the dependency libs installed, this is part of my static ffmpeg build script ( with librtmp and libx265 and x11grab)

• 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

  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 ?
