• Filter concat has an unconnected output while Video concatenation in ffmpeg wrapper in java

  28 février 2024, par Thor

  I am trying to stitch variable number of videos using ffmpeg wrapper.

  


  I have this code :

  


  private void videoStich(List<string> videoPaths){&#xA;        FFmpeg ffmpeg = null;&#xA;        FFprobe ffprobe=null;&#xA;        String stitchedOutputPath = outputFolder &#x2B; "/stitched_output.mp4";&#xA;&#xA;        try {&#xA;            ffmpeg = new FFmpeg();&#xA;            ffprobe = new FFprobe();&#xA;        } catch (IOException e) {&#xA;            throw new RuntimeException(e);&#xA;        }&#xA;&#xA;&#xA;        FFmpegBuilder builder = new FFmpegBuilder();&#xA;&#xA;        for (int i = 0; i &lt; videoPaths.size(); i&#x2B;&#x2B;) {&#xA;            String videoPath = videoPaths.get(i);&#xA;            builder.addInput(videoPath);&#xA;        }&#xA;&#xA;        // Add complex filter for concatenation&#xA;        StringBuilder complexFilter = new StringBuilder();&#xA;        for (int i = 0; i &lt; videoPaths.size(); i&#x2B;&#x2B;) {&#xA;            complexFilter.append("[").append(i).append(":v][").append(i).append(":a]");&#xA;//            if (i &lt; videoPaths.size() - 1) {&#xA;//                complexFilter.append("[");&#xA;//            }&#xA;        }&#xA;        complexFilter.append("concat=n=").append(videoPaths.size()).append(":v=1:a=1[v][a]");&#xA;&#xA;        builder.setComplexFilter(complexFilter.toString())&#xA;                .addOutput(stitchedOutputPath)&#xA;                .setFormat("mp4")&#xA;                .done();&#xA;&#xA;        FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);&#xA;        executor.createJob(builder).run();&#xA;    }&#xA;</string>

  


  but getting this error :

  


  2024-02-28T16:30:53.033+05:30  INFO 4711 --- [sample_project] [pool-3-thread-1] net.bramp.ffmpeg.RunProcessFunction      : ffmpeg -version

Filter concat has an unconnected output
java.lang.RuntimeException: java.io.IOException: ffmpeg returned non-zero exit status. Check stdout.


  


  I have been trying to fix this since a long time and didn't find any issue with the filter, it is looking good to me. Can anyone help me with it ?

  


  EDIT :
I found that when I use this command in terminal :

  


  ffmpeg -i in1.mp4 -i in2.mp4\
            -filter_complex "[0:v] [0:a] [1:v] [1:a] \
concat=n=2:v=1:a=1 [v] [a]" \
            -f mp4  output_test5.mp4


  


  it didn ;t work
while when i used this :

  


  ffmpeg -i in1.mp4 -i in2.mp4\
            -filter_complex "[0:v] [0:a] [1:v] [1:a] \
concat=n=2:v=1:a=1 [v] [a]" \
            -f mp4 -map "[v]" -map "[a]" output_test4.mp4


  


  it worked. I think i need to add -map "[v]" -map "[a]" somehow in the code.

  


  but when i try to add :
builder.setComplexFilter(complexFilter.toString())
.addOutput(stitchedOutputPath)
.setFormat("mp4")
.map()
.done() ;

  


  or

  


  builder.setComplexFilter(complexFilter.toString())
.addOutput(stitchedOutputPath)
.setFormat("mp4")
.setMap()
.done() ;

  


  both .set() or setMap() doesn't exist. What to do, how to do ?

• I have an MJPEG file decoded with the Intel® IPP JPEG encoder [8.1.42291], how can I convert it to MP4 using ffmpeg ? [closed]

  When trying to convert the MJPEG file with ffmpeg, it gives the following error : Output file #0 does not contain any stream.
