• Android FFmpeg mp41 fps drop

  4 mai 2020, par Yiğit Can YILMAZ

  I am using FFmpeg to trim videos in my project. It's working well with most of the videos. But, I am having problems with some videos that have isomiso2avc1mp41 format. I am not familiar with video proccessing part but when i watch video it seems like having fps drop problem.

  



  I have tried some methods like addding -framerate 24 or -r 24 to FFmpeg execution commands to set fps rate and converting mp41 to mp42 by using -brand mp42 but I could not achieved to overcame this problem. Can anyone help me to figure this out, please ?

  



  Thanks

  



  this my code snippet :

  



  String[] cropCommand = {"-y", "-i", inputFile, "-ss", "" + startMs / 1000, "-t", "" + (endMs - startMs) / 1000, "-c", "copy", outputFile};

        Log.i("cropcommand", Arrays.toString(cropCommand));
        final int finalHeight = height;
        final int finalWidht = width;
        FFmpeg.getInstance(context).execute(cropCommand, new ExecuteBinaryResponseHandler() {

            @Override
            public void onFailure(String message) {
                //   callback.onCancel();

            }

            @Override
            public void onProgress(String message) {
                super.onProgress(message);
                Log.e("ffmpeg", message);
            }

            @Override
            public void onSuccess(String s) {

                Log.i("videosize", "output " + String.valueOf(getFileSize(outputFile)));

            }

            @Override
            public void onStart() {
                Log.i("videosize", "input " + String.valueOf(getFileSize(inputFile)));

            }
        });
    } catch (FFmpegCommandAlreadyRunningException e) {
        e.printStackTrace();
        //  callback.onCancel();
    }


  



  and this is log of trial with issue :

• Can't connect to ffserver when running on android device

  11 décembre 2016, par Antonio C G

  I am working on an android app. This will run a ffserver (on the device, not another computer). The server is running and I can access the status page, everything seems ok. But when I try to send the video using ffmpeg I always get connection refused.

  This is my ffserver.conf file :

  I connect to server using this command :

  Does anybody know what could be wrong ?
  Just to be clear, I recompiled ffserver and ffmpeg for android. They both seem to be ok as I can execute commands. Both binaries are part of the app, so everything runs inside the phone.

  Thanks.

• Android FFmpeg sometimes works and sometimes crashes

  20 novembre 2013, par Pawel Cala

  I compiled FFmpeg for Android ( https://gitorious.org/android-ffmpeg ) but when I'm trying to do some operations ( f.e filters cropping, transpose, trim etc ) it crashes in 5 on 10 cases.
  Error logs are not the same so I assume that it might be caused by memory issues.
  I'm using OSX, NDK android-ndk-r9b : darwing x86_64.
  Native ffmpeg method is passing args to ffmpeg.c main method. It's executed in AsyncTask in Activity.
  Thanks in advance

  EDIT :
  I forgot to mention that programs algorithm runs like that :
  Press Button - > Open Camera Intent - > Start recording - > After recording copy file to project folder ( on SD card ) - > Open edit activity + Start asynctask

  EDIT2 :
  Tested on HTC ONE with different video resolutions
