• How to create a video from image buffers using fluent-ffmpeg ?

  23 juin 2016, par Zacky Pickholz

  I’ve been trying to create a slideshow from a series of images using nodejs + fluent-ffmpeg, however it is not working well or consistently. ffmpeg occasionally emits "Error : ffmpeg exited with code 1 : pipe:0 : Invalid data found when processing input", and in case an eventual video (mp4) is created it seems to be missing images/frames.

  The process is as follows : images are loaded into memory, transformed resized to same dimensions using lwip, written sequentially into a passthrough stream, which is fed to ffmpeg as input.

  Relevant code snippets :

  var lwip = require('lwip');
  
  var ffmpeg = require('fluent-ffmpeg');
  
  var stream = require('stream');
  
  var imagesStream = new stream.PassThrough();
  
  
  
  ...
  
  
  
  image.batch()
  
              .contain(options.video.width, options.video.height, 'lanczos')
  
              .toBuffer(options.frames.format, {quality: 100}, (err, buffer) => {
  
                  if (err) {
  
                      throw ('error convering image to buffer. ' + err);
  
                  }
  
                  imagesStream.write(buffer, 'utf8');
  
                  resolve();
  
              });
  
  
  
  ...
  
  
  
      ffmpeg(imagesStream)
  
          .inputOptions('-framerate 1/' + options.frames.secsPerImage)
  
          .input(path.join(AUDIO_ROOT, options.audio.track))
  
          .save(path.join(path.join(OUTPUT_FOLDER, `${options.video.output.prefix}${timestamp}.${options.video.output.format}`)))
  
          .size(`${options.video.width}x${options.video.height}`)
  
          .on('start', () => {
  
              console.log('creating the clip now...')
  
          })
  
          .on('progress', (progress) => {
  
              var progPercent = Math.round(100 * progress.frames / (numImages * options.frames.secsPerImage * 25));
  
              progPercent = Math.min(progPercent, 100);
  
              console.log(`processing: ${progPercent}% done`)
  
          })
  
          .on('stderr', (line) => {
  
              console.error('ffmpeg error: ' + line);
  
          })
  
          .on('error', (error) => {
  
              reject('ffmpeg transcoding error: ' + error);
  
          })
  
          .on('end', () => {
  
              console.log('done!');
  
              resolve(true);
  
          })
  
          .run();

  And here is the output :

• Building my own FFmpeg for android in Ubuntu 14.04 LTS (Vitamio)

  16 août 2016, par EduardoUstarez

  I am trying to build FFmpeg because I realized that my app doesn’t work for android 6.0 in x86 devices before that I have published my app with targetsdkversion 23 (It has text relocations) and now I can’t publish my app using targetsdkversion 22 (This is the way that I could fix the problem). So I read a lot about this problem It seems there isn’t a solution. Some people say that I can compile ffmpeg using —disable-asm flag and I can solve the problem. I want to generate a libffmeg.so for vitamio that works on x86 android 6.0.

  I am using

  Ubuntu 14.04 LTS

  Android NDK r12b

  And my example project is Vitamio-5.0.2 from Download

  So I am working on this tutorial

  The other files are the same as url provides

  Then the result is

  

  I have deleted -Werror=strict-aliasing from CFLAGS and it generates the other .so files less libffmpeg.so

  

  The error is in this code line

  $CC -lm -lz -shared --sysroot=$SYSROOT -Wl,--no-undefined -Wl,-z,noexecstack $EXTRA_LDFLAGS libavutil/*.o libavutil/arm/*.o libavcodec/*.o libavcodec/arm/*.o libavformat/*.o libswresample/*.o libswscale/*.o -o $PREFIX/libffmpeg.so

  I have removed ccache from export CC="ccache arm-linux-androideabi-gcc"
  and I have an error

  

  I have changed —disable-asm to —enable-asm and I have compiled FFmpeg-Android.sh correctly

  

  I copied the libffmpeg.so generated in armv6, armv7, neon and vfp files in my android studio project.

  I don’t know if I copied libffmpeg.so files in the correct place

  armv6 -> arm64-v8a
  
  armv7 -> armeabi-v7a
  
  neon  -> x86

  

  And the result in Android Studio

• Change AVI creation date with ffmpeg ?

  1er novembre 2016, par brock

  As far as I can tell the following ffmpeg command should copy all existing metadata in the input file to the output file and modify the specified field in the output file :

  ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.avi

  Instead, it seems to strip all metadata from the output file. Here is the output of a few commands. I am going nuts. I think this should work, but why is it not ?

  Command to edit the creation time :

  ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.avi
