• 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 \
  
  \
  
  --disable-doc \
  
  --enable-yasm \

  --enable-decoders \

  --enable-encoders \
  
  --enable-muxers \
  
  --enable-demuxers \
  
  --enable-parsers \
  
  --enable-protocols \
  
  --enable-protocol=http \
  
  --enable-filters \
  
  --enable-avresample \
  
  \
  
  --disable-indevs \
  
  --enable-indev=lavfi \
  
  \
  
  --enable-hwaccels \
  
  \
  
  --enable-ffmpeg \
  
  --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 :

• FFmpeg for automatic video generation from images ?

  22 janvier 2018, par Dionisis K

  I want to implement an automatic video generation from images, like facebook’s anniversary video. And I would also like to add some filters. I’ve been searching a lot and read FFmpeg’s documentation which is pretty amazing.

  In the future I want to have 10-20 "bashscripts" with different filters leading to different themes (e.g. fade-in, zoom, overlay images, left-to-right, etc..)

  So my biggest concern is having an interface which offers readable code and provides scalability. Since ffmpeg is a bashscript i searched for a wrapper

  There are wrappers in

  • https://github.com/PHP-FFMpeg/PHP-FFMpeg for php ,which doesn’t support image convertion to videos and complex filters .
  • https://github.com/fluent-ffmpeg/node-fluent-ffmpeg which looks promising but also difficult to go with complex filters
  • and https://github.com/kkroening/ffmpeg-python for python.I think that it s pretty good

  Are there any other wrappers worth to check ?
  Would you recommend something from the above ?
  Is there any pros and cons using a specific programming language for this particular case ?
  Is there anything else i should bear in mind before I make a decision ?

• Overlay Image on moving object in Video (Argumented Reality / OpenCv)

  30 juillet 2017, par Karandeep Atwal

  I am using FFmpeg to overlay image/emoji on video by this command -

  "-i "+inputfilePath+" -filter_complex "+"[0][1]overlay=enable='between(t,"+startTime+","+endTime+")'[v1]"+" -map [v0] -map 0:a "+OutputfilePath;  

  But above command only overlay image over video and stays still.

  In Instagram and Snapchat there is New pin feature. I want exactly same ,eg blur on moving faces or as in below videos -

  

  Here is link.

  Is it possible via FFmpeg ?

  I think someone with OPENCV or Argumented Reality knowledge can help in this. It is quiet similar to AR as we need to move/zoom emoji exactly where we want to on video/live cam.
