Submit enhancements and plugins
13 avril 2011If you have developed a new extension to add one or more useful features to MediaSPIP, let us know and its integration into the core MedisSPIP functionality will be considered.
You can use the development discussion list to request for help with creating a plugin. As MediaSPIP is based on SPIP - or you can use the SPIP discussion list SPIP-Zone.

Making ffmpeg/javacv less verbose in java
16 octobre 2022, par lejlotI have a Java application that uses
ffmpeglibrary andjavacvto load and process video files.


I am currently using following code, for loading
videofileto my data container.


public boolean add(String videofile) {
 FrameGrabber g = new OpenCVFrameGrabber( videofile );
 try{ 
 g.start();
 }
 catch(Exception e){
 g = new FFmpegFrameGrabber( videofile );
 try {
 g.start();
 }catch(Exception x){
 return false;
 }
 }
 grabbers.add( new Pair(videofile, g) );
 frames.add( 0 );
 preprocessed=false;
 return true; 
 }



Each time video is loaded, a library outputs a lot of meta information regarding video itself :





Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/home/lejlot/data/test.mp4' : 
 Metadata :
 major_brand : isom
 minor_version : 512
 compatible_brands : isomiso2mp41
 encoder : Lavf53.21.1 Duration : 00:04:36.27, start : 0.000000, bitrate : 305 kb/s
 Stream #0:0(und) : Video : mpeg4 (Simple Profile) (mp4v / 0x7634706D), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 303 kb/s, 20,85
 fps, 30 tbr, 1k tbn, 1k tbc
 Metadata :
 handler_name : VideoHandler





which obviously I do not want to see. I cannot (do not want) to modify the libraries source codes, but rather modify my own so it can intercept this log and discard it.



As far I tried to temporarly block the stdout/stderr streams through



private static final devnull = new PrintStream(new OutputStream() {
 @Override
 public void write(int b) {
 //DO NOTHING
 }
 @Override
 public void write(byte[] b,int x,int y){
 }
 });

 /**
 * Blocks messages to stdout
 */
 public static void silentStdOut(){
 System.setOut(devnull);
 }

 /**
 * Blocks messages to stderr
 */
 public static void silentStdErr(){
 System.setErr(devnull);
 }



but it does not seem to help, log message is still displayed



public boolean add(String videofile) {
 Utils.silentStdErr();
 Utils.silentStdOut();
 FrameGrabber g = new OpenCVFrameGrabber( videofile );
 try{ 
 g.start();
 }
 ,,,



"Raw" ffmpeg can be set to be less verbose using



ffmpeg -loglevel panic



but neither
OpenCVFrameGrabbernotFFmpegFrameGrabbergive access to the tool's parameters.


To sum up - how can I discard these log messages without modifing the libraries' source codes ?
