• FFMPEG "no such file or directory" on Android

  25 mars 2013, par Feras

  I am trying to use the ffmpeg binary and call it via a native linux command in android. Most of the commands work fine but the problem is that when i need to pass an http url as an input to the -i option i get "No such file or directory" for the url. The url however is existing and running the SAME command on a mac does the job as expected.

  Here is my compile config for the ffmpeg build :

  ./configure \
  
  $DEBUG_FLAG \
  
  --arch=arm \
  
  --cpu=cortex-a8 \
  
  --target-os=linux \
  
  --enable-runtime-cpudetect \
  
  --prefix=$prefix \
  
  --enable-pic \
  
  --disable-shared \
  
  --enable-static \
  
  --cross-prefix=$NDK_TOOLCHAIN_BASE/bin/$NDK_ABI-linux-androideabi- \
  
  --sysroot="$NDK_SYSROOT" \
  
  --extra-cflags="-I../x264 -mfloat-abi=softfp -mfpu=neon" \
  
  --extra-ldflags="-L../x264" \
  
  \
  
  --enable-version3 \
  
  --enable-gpl \

  --enable-ffplay \
  
  --enable-libmp3lame \
  
  --enable-network \
  
  \
  
  --enable-libx264 \
  
  --enable-libfaac \
  
  --enable-zlib

  Its based off of this project : https://github.com/guardianproject/android-ffmpeg-java

  Command is something along the lines of that :

  ffmpeg -i "http://someurl" -f mp3 -ab 192000 -vn demoo.mp3

  The idea being to download the audio track from a video and encode it as mp3. I explicitly added multiple enable protocols options but nothing seems to do the job. I tried an alternative config as well, removing everything below enable-gpl just to make sure there arent any conflicts, but it fires the same error. If i give it a normal filesystem path it works fine.

  Following the comments here is the exact output of the command and the output :

• PHP ffmpeg conversion error

  6 mars 2016, par Enn Fenn

  I tried to convert some videos with ffmpeg and PHP.

  When I execute the following command in PHP exec()

  /usr/local/bin/ffmpeg -i /home/test/public_html/test.m4v -vcodec libx264 -acodec libmp3lame -r 30 -s 640x480 -b 100k /home/test/public_html/output_640x480_test.m4v

  The same conversion is working fine in another server. But not in our current server. What should I do to get rid of this error ?
