Java shelling out to FFMPEG not running nor giving error
4 janvier, par ToddI'm writing a Podcast downloader where I want to be able to download one or more podcasts then run them through FFMPEG.


It does run when I run the program in Windows.

It does not run when I run the program in Linux - Meaning FFMPEG may or may not have been called. I have no way of knowing. I get a -1 back from process.waitfor() but no error in my Java logs and no entries at all in the ffmpeg.log file. And there is no file in the processed file directory that FFMPEG would have created.

It does run in Linux if I run the same command that fails in Java from the command line.

FFMPEG has the permissions : rwxr-xr-x , so it doesn't seem as if it'd be a permission error. The Java code looks like :


ProcessBuilder processBuilder = new ProcessBuilder( commands );
 processBuilder.redirectErrorStream( true );
 // Added the next line to see if I could log an error from ffmpeg
 processBuilder.redirectOutput( ProcessBuilder.Redirect.appendTo( new File( "./ffmpeg.log" ) ) );

 Process process = processBuilder.start();
 BufferedReader bufferedOutputReader = new BufferedReader( new InputStreamReader( process.getInputStream() ) );
 do {
 outputString = bufferedOutputReader.readLine();
 if ( outputString != null ) {
 LOGGER.trace( outputString );
 }
 } while ( outputString != null );
 results = process.waitFor();
 LOGGER.debug( "Exit value: " + results );


The commands are :


2023-10-25 16:21:52,452 224257 [pool-1-thread-4] DEBUG org.sperbolink.utils.CodecUtils - command string: /bin/ffmpeg 
2023-10-25 16:21:52,452 224257 [pool-1-thread-4] DEBUG org.sperbolink.utils.CodecUtils - command string: -y

And the manually constructed and run command line that DOES work is :


/bin/ffmpeg -y -i "/home/todd/aggregator/incoming/Downrange Radio/Downrange_Radio_2023-02-15_The_Avidity_PD-10_Delivers_.mp3" -ac 1 -af "atempo=1.4,volume=1.4" "/home/todd/aggregator/processed/Downrange Radio/Downrange_Radio_2023-02-15_The_Avidity_PD-10_Delivers_.mp3"


The ffmpeg.log file is empty, so I'm doubting whether FFMPEG is ever being reached.


What am I doing wrong ?


EDIT :
I changed the commands to be


"/bin/ffmpeg 2> foo.txt" 


and the execution code to :


ProcessBuilder processBuilder = new ProcessBuilder( commands );
// processBuilder.redirectErrorStream( true );
 // Added the next line to see if I could log an error from ffmpeg
// processBuilder.redirectOutput( ProcessBuilder.Redirect.appendTo( new File( "./ffmpeg.log" ) ) );
 Process process = processBuilder.start();
 results = process.waitFor();


Running that command from the command line displays a list of MMPEG commands that can be run within foo.txt. Upon running from within the Java app, the foo.txt file is empty, so it doesn't appear that FFMPEG ever gets reached. But, I'm clueless why not.


EDIT 2 :
I converted the /bin/ffmpeg path to uppercase to see if that would return an error and it did.


ERROR org.mrpc.utilities.ShellUtils - Cannot run program "/BIN/FFMPEG": error=2, No such file or directory


This seems to confirm that the Java Process object can locate ffmpeg successfully when it is properly cased (i.e. my original code) as I don't see an error message when the case is incorrect. Still not sure why nothing happens when it is called.


EDIT 3 :
I punted on this a year ago, but recently had to revisit. This time I found the answer. It is because I included double quotes around some of the command parameters. That caused the files to not be found. This link states that the Process class handles embedded spaces without any intervention required by you : ProcessBuilder adds extra quotes to command line

Cropping a video from Sony A7 Camera using ffmpeg
23 octobre 2023, par Mike SlinnI want to crop a video file created by a Sony A7iii camera, so only the portion from 0:51 through 2:45 is extracted.
The camera adds streams that need to be ignored.


ffprobeshows the error on input stream 2, however the problem I am reporting deals with input stream 3, which is a data stream, and is not required. I want to exclude input stream 3, then deal with input stream 2.

I tried various incantations that specified permutations of

How might I perform the extraction ? I am not interested in preserving extra streams, I just want the main video and stereo audio streams.

Convert mp4/mov/... to mp4 with fluent-ffmpeg
13 octobre 2023, par Sam LeursI have a lambda function which reads a video from s3, converts it with fluent-ffmpeg and streams the video back to (another bucket in) s3.


This is the code so far :


ffmpeg()
 .input(readstream.Body)
 .format('mp4')
 .addOutputOption("-preset veryfast")
 .addOutputOption("-movflags frag_keyframe+empty_moov")
 .addOutputOption("-crf 28")
 .output(writestream, { end: true })
 .on('error', (err, stdout, stderr) => {
 console.log(err);
 console.log('Stdout: %o', stdout);
 console.log('Stderr: %o', stderr);
 })
 .run();


With an input mp4 file, this code works, but with a mov-file it fails. I get the following error :


Error: ffmpeg exited with code 1: Error demuxing input file 0: Invalid data found when processing input
pipe:0: Invalid data found when processing input
Cannot determine format of input stream 0:0 after EOF
Error marking filters as finished
Conversion failed!

Is it possible to convert multiple filetypes with one fluent-ffmpeg chain. If not, can someone help me to make a chain for mov ?
