Get last received statistics

[shiv71]

Is any method in FFmpegKit like below to get last received statistics in android
Statistics statistics = Config.getLastReceivedStatistics(); this is in mobile-ffmpeg library

See the Migrating From MobileFFmpeg Android API wiki page.

Config.getLastReceivedStatistics() can be replaced with FFmpegKitConfig.getLastSession().getLastReceivedStatistics().

[shiv71]

I am using this library : com.arthenica:ffmpeg-kit-min:4.4.LTS
I have checked both methods but not find the getLastReceivedStatistics() method

FFmpegKitConfig.getLastSession().getLastReceivedStatistics()
FFmpegKitConfig.getLastCompletedSession().getLastReceivedStatistics()

getLastSession() method return Session class object and getLastReceivedStatistics() not exist in this class.
I have check in library code getLastReceivedStatistics() method exist in the FFmpegSession class.

[tanersener]

You're right. Statistics is a feature provided for FFmpeg sessions only. And, getLastSession() returns a Session. So, that call will give you a compiler warning. Can you try by casting getLastSession() to FFmpegSession first?

((FFmpegSession)FFmpegKitConfig.getLastSession()).getLastReceivedStatistics()

[shiv71]

Statistics statistics = ((FFmpegSession)FFmpegKitConfig.getLastSession()).getLastReceivedStatistics();

This is not working it's returning null.

[tanersener]

If ffmpeg generates statistics for your command that statement will return it. If it returns null that means that ffmpeg didn't generate statistics.

Besides, if you suspect something is not working as expected then you need to provide more details e.g. logs.

[shiv71]

Statistics statistics = ((FFmpegSession)FFmpegKitConfig.getLastSession()).getLastReceivedStatistics();
I have debugged the code and it's returning statistics value but returning the same value.

I am using statistics for calculation progress. Below is my code.

 final Handler handler = new Handler();
        final int delay = 200; // 1000 milliseconds == 1 second

        handler.postDelayed(new Runnable() {
            public void run() {
                Statistics statistics = ((FFmpegSession)FFmpegKitConfig.getLastSession()).getLastReceivedStatistics();
                int progress = 0;
                if (statistics != null){
                    Log.e("Statistics", statistics.toString());
                }

                if (statistics != null && statistics.getSessionId() == executionId) {
                    try {
                       // calculating the compression progress
                        progress = (int) ((statistics.getTime() / Double.parseDouble(duration)) / 10);
                        int pro = progress + bgPostDataModel.getCurrentBarLength();
                        if (pro <= 100) {
                            String remainingTime = BGUtils.calculateRemeaningTime(statistics.getTime(), ((long) Double.parseDouble(duration)) * 1000, compressionStartedTime, BGState.COMPRESSING);

                            sendBroadcastMsg(true, uploading, progress + bgPostDataModel.getCurrentBarLength(), false, remainingTime);
                            uploadProgressNotification.updateProcess(progress + bgPostDataModel.getCurrentBarLength(), remainingTime);
                        }


                    } catch (Exception e) {

                    }
                }
                if (!isCompressionComplete && progress < 100)
                    handler.postDelayed(this, delay);
            }
        }, delay);

Thanks. It seems like there is a bug there.

Can you use the following snippet until it is fixed.

List<Statistics> statisticsList = ((FFmpegSession) FFmpegKitConfig.getLastSession()).getStatistics();
statisticsList.get(statisticsList.size() - 1);

[tanersener]

Fixed in the development branch.
