• When reading a file line by line, I only get to execute ffmpeg on the first line

  12 avril 2016, par Shmuel

  I’m writing a Bash script in which I read a file line by line ( well, <(find /home/user/ -iname "*.MP4") to be exact ) , and for each line I execute ffmpeg, so I’m doing something like this :

  while read -r line; do
  
      ffmpeg -i "$line" [ MORE OPTIONS ... ]
  
  done < <(find /home/user/ -iname "*.MP4")

  Though, for some reason, only the first line is being processed successfuly.

  Any idea why my code ignores all other lines ?

• Android FFmpeg build : cannot find -lavutil

  4 novembre 2016, par Jon G

  I am trying to build FFmpeg for Android JNI using the guide here (forked from appunite’s build). One difference between my build and theirs is that I am trying to use the FFmpeg master branch instead of commit 82db8ee, maybe that is relevant. I am coming across a build issue when I try to build for multiple architectures in a row.

  The code that is running is :

  ${LD} -rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -L$PREFIX/lib -soname $SONAME -shared -nostdlib -Bsymbolic --whole-archive --no-undefined -o $OUT_LIBRARY -lavformat -lavcodec -lx264 -lavfilter -lavutil -lswscale -lswresample -lavresample -lfribidi -lvo-aacenc -lvo-amrwbenc -lpostproc -lc -lm -lz -ldl -llog --dynamic-linker=/system/bin/linker -zmuldefs $PREBUILT/lib/gcc/$EABIARCH/$COMPILATOR_VERSION.x/libgcc.a

  The logs that are outputted in the MIPS case are :

  ...
  
  FINISHED ffmpeg for mips
  
  + build_one
  
  + echo 'Starting build one for mips'
  
  Starting build one for mips

  /home/jon/Development/android-ndk-r10e/toolchains/mipsel-linux-android-4.9/prebuilt/linux-x86_64/bin/mipsel-linux-android-ld: cannot find -lavutil

  Everything seems successful until that point. Why would libavutil.a be incompatible ?

  I find that if I revert FFmpeg to commit 82db8ee, build for MIPS (successful), change back to master, then build for MIPS again, it does not raise the error. Perhaps something is not being cleaned up properly ?
