Yet another ffmpeg concat audio sync issue [closed]
15 mars 2024, par DemiurgI've read through dozens of posts, tried many suggestions, nothing seems to work for me. The funny part is that the video is fine in some players (e.g. Quicktime) but not the others (e.g. Chrome).


This is what I currently use :


ffmpeg -i segment.mp4 -q 0 -c copy segment.ts
ffmpeg -f concat -i videos.txt -c copy -y final.mp4


This is what ffmpeg shows for the originals

Filter concat has an unconnected output while Video concatenation in ffmpeg wrapper in java
28 février 2024, par ThorI am trying to stitch variable number of videos using ffmpeg wrapper.


I have this code :


private void videoStich(List<string> videoPaths){
 FFmpeg ffmpeg = null;
 FFprobe ffprobe=null;
 String stitchedOutputPath = outputFolder + "/stitched_output.mp4";

 try {
 ffmpeg = new FFmpeg();
 ffprobe = new FFprobe();
 } catch (IOException e) {
 throw new RuntimeException(e);
 }


 FFmpegBuilder builder = new FFmpegBuilder();

 for (int i = 0; i < videoPaths.size(); i++) {
 String videoPath = videoPaths.get(i);
 builder.addInput(videoPath);
 }

 // Add complex filter for concatenation
 StringBuilder complexFilter = new StringBuilder();
 for (int i = 0; i < videoPaths.size(); i++) {
 complexFilter.append("[").append(i).append(":v][").append(i).append(":a]");
// if (i < videoPaths.size() - 1) {
// complexFilter.append("[");
// }
 }
 complexFilter.append("concat=n=").append(videoPaths.size()).append(":v=1:a=1[v][a]");

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

 FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);
 executor.createJob(builder).run();
 }
</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
2024-02-28T16:30:53.126+05:30 INFO 4711 --- [sample_project] [pool-3-thread-1] net.bramp.ffmpeg.RunProcessFunction : ffmpeg -y -v error -i src/main/resources/cutted_videos/0_trimmed.mp4 -i src/main/resources/cutted_videos/1_trimmed.mp4 -filter_complex [0:v][0:a][1:v][1:a]concat=n=2:v=1:a=1[v][a] -f mp4 src/main/resources/cutted_videos/stitched_output.mp4
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 ?
