The filter complex does not put te quotation marks and null problem #53
Comments

It's just a log message, there is no need to escape spaces or wrap
parameters with quotes because it's done by Java process executor. So if it
works, it's ok.

… I try to trim videos and concat them. I want to create the following
command like that
./ffmpeg -i ../Desktop/ramb.mp4 -filter_complex
"[0:v]trim=start=0:end=5,setpts=PTS-STARTPTS[0]; [0:v]trim=start=10 :
end=15,setpts=PTS-STARTPTS[1]; [0][1]concat[2];
[0:v]trim=start=25,setpts=PTS-STARTPTS[3]; [2][3]concat [out1]" -map [out1]
../Desktop/cut_ramb2.mp4
but command constructed like this:
ffmpeg -i /var/www/contents/rawVideo/30_Rambo.mp4 -y -filter_complex
[0:v]trim=start=0.0:end=2.0:setpts:PTS-STARTPTS[0];
[0:v]trim=start=5.0:end=15.0:setpts:PTS-STARTPTS[1]; [0][1]null=concat[2];
[0:v]trim=start=40.0:end=45.0:setpts:PTS-STARTPTS[3]; [2][3]null=concat[4]
-map [4] /var/www/contents/trimmedVideo/trimmed_30_Rambo.mp4
and I am using Jaffre-wrapper in Java Code like this:
` FilterChain filterChain = new FilterChain();
filterChain.addFilter(
Filter.fromInputLink(StreamSpecifier.withInputIndexAndType(0,StreamType.VIDEO)).
setName("trim").
addArgument("start",start.toString()).
addArgument("end",end.toString()).
addArgument("setpts").
addArgument("PTS-STARTPTS").
addOutputLink(String.valueOf(outIndex++))
);
filterChainList.add(filterChain);
if(i != 0){
FilterChain filterChain1 = new FilterChain();
filterChain1.addFilter(
Filter.fromInputLink(String.valueOf(outIndex-2)).
addInputLink(String.valueOf(outIndex-1)).
addArgumentEscaped("concat").
addOutputLink(String.valueOf(outIndex++))
);
filterChainList.add(filterChain1);
}`
return FilterGraph.of().addFilterChains(filterChainList);
` FilterGraph filterGraph = createFilterChain();
FFmpegResult result = FFmpeg.atPath(ffmpegBin)
.addInput(UrlInput.fromPath(input))
.setOverwriteOutput(true)
.setFilter(filterGraph.getValue())
.addArgument("-map")
.addArgument("[" + out + "]")
.addOutput(UrlOutput.toPath(output))
.execute();`
Thanks for this project. This project helped me a lot.

@tarikkilic when constructing filter you have to specify filter name, but you specify Also note the difference bnetween FilterChain and Filter: |

Thank you very much. This problem solved. And last question : Jaffre constructed command like this: I copied command from first screenshoot and paste terminal, ffmpeg works but throw exception in java program. I didn't understand. |
|
To get detailed message you need to enable trace logs for Jaffree. Paste logs here if you need more help. |

Is that what you meant? and my ffmpeg code:
|

Yes, the error message is the following: With Java process executor you don't need to escape or quot arguments. Probably you can't escape or quot. So just remove |

Problem Solved! Thanks a lot. But If I write ffmpeg in command-line, I must put quotationmarks to filter. But with Java process executor, I don't put quotation marks and works ffmpeg. I'm confused. Issue can be closed. Again thanks. |
I try to trim videos and concat them. Doesn't put quatation marks and null=concat instead of only using concat. And [0:v]trim=start=0.0:end=2.0:setpts:PTS-STARTPTS[0]; after could be setpts=PTS-STARTPTS but couldn't. I want to create the following command like that
./ffmpeg -i ../Desktop/ramb.mp4 -filter_complex "[0:v]trim=start=0:end=5,setpts=PTS-STARTPTS[0]; [0:v]trim=start=10 : end=15,setpts=PTS-STARTPTS[1]; [0][1]concat[2]; [0:v]trim=start=25,setpts=PTS-STARTPTS[3]; [2][3]concat [out1]" -map [out1] ../Desktop/cut_ramb2.mp4but command constructed like this:
ffmpeg -i /var/www/contents/rawVideo/30_Rambo.mp4 -y -filter_complex [0:v]trim=start=0.0:end=2.0:setpts:PTS-STARTPTS[0]; [0:v]trim=start=5.0:end=15.0:setpts:PTS-STARTPTS[1]; [0][1]null=concat[2]; [0:v]trim=start=40.0:end=45.0:setpts:PTS-STARTPTS[3]; [2][3]null=concat[4] -map [4] /var/www/contents/trimmedVideo/trimmed_30_Rambo.mp4and I am using Jaffre-wrapper in Java Code like this:
FilterChain filterChain = new FilterChain();return FilterGraph.of().addFilterChains(filterChainList);FilterGraph filterGraph = createFilterChain();Thanks for this project. This project helped me a lot.
