• rtmpdump not stopping live steam capture with -B option set

  16 janvier 2016, par Byron

  I have an rtmp url that, when I try to capture with the command rtmpdump -r "url" -B 5 -v -o test.flv, the program starts successfully, but does not exit after 5 seconds, even when the console output says "For duration : 5 seconds". If I break with ^C, the file is captured successfully.

  Note that the seconds output in this example must be the seconds since the stream started running not of the capture length time. console output

• Video Processing in background with work manager using ffmpeg

  24 novembre 2020, par Naseer Attari

  The problem comes when during the video processing user closes the application himself from the task manager then its processing stops.

  


  I am working on video file processing in android using FFMpeg, which is working perfectly but when I do close the application during processing from task manager then video processing has stopped working even I added all the work in work manager.

  


      @Override 
public Result doWork() {
        shellCommand = new ShellCommand();
        ffmpegBinary = new String[] {
            FileUtils.getFFmpeg(context).getAbsolutePath()
        };
        command = concatenate(ffmpegBinary, command);
        CommandResult commandResult = getCommandResult(command);
        if (command`enter code here`Result.success) {
            onSuccess(videoPath);
        } else {
            onFailure(videoPath);
        }
    }
    //getCommandResult
    private CommandResult getCommandResult(String[] command) {
        try {
            process = shellCommand.run(command, null);
    
            if (process == null) {
                return CommandResult.getDummyFailureResponse();
            }
            checkAndUpdateProcess();
            return CommandResult.getOutputFromProcess(process);
        } catch(Exception e) {} finally {
            Util.destroyProcess(process);
        }
        return CommandResult.getDummyFailureResponse();
    }


  


  As far as I can tell, when the application closes from the background then the parent process destroys it and is destroying all of its sub-process too, FFMpeg is using the android process to execute the command and check the video file status during video processing.

  


  Looking forward to hear from you.
Thanks

  


• ffmpeg : Generate video's thumbnail in original orientation in php

  6 juillet 2017, par user2899728

  I am trying to generate thumbnail from a video. My command is working fine but it is generating thumbnail in wrong orientation.

  I want to keep same orientation of the video I am using.

  Here is my command :

  exec("ffmpeg  -i  567293a3a6b48.mp4 -ss   01:00  -vframes 1  thumbnail.jpg");

  Also thumbnail does not contain any orientation info in exif data.
