  • Using JavaCV and FFMpeg how to get high quality video preview

    22 avril 2015, par Munchoo

    Hi am using JavaCV to record a video and save it. But the quality is very low.
    Can anybody suggest what specifications we need to give for a good high quality video. The below code is used

    @Override
    
    public void onPreviewFrame(byte[] data, Camera camera) {
    
        /* get video data */
    
        long frameTimeStamp = 0L;
    
        if(mAudioTimestamp == 0L && firstTime > 0L)
    
            frameTimeStamp = 1000L * (System.currentTimeMillis() -firstTime);
    
        else if (mLastAudioTimestamp == mAudioTimestamp)
    
            frameTimeStamp = mAudioTimestamp + frameTime;
    
        else
    
        {
    
            long l2 = (System.nanoTime() - mAudioTimeRecorded) / 1000L;
    
            frameTimeStamp = l2 + mAudioTimestamp;
    
            mLastAudioTimestamp = mAudioTimestamp;
    
        }
    
        synchronized (mVideoRecordLock) {
    
            if (recording && rec && lastSavedframe != null && lastSavedframe.getFrameBytesData() != null && yuvIplImage != null)
    
            {
    
                mVideoTimestamp += frameTime;
    
                if(lastSavedframe.getTimeStamp() > mVideoTimestamp)
    
                mVideoTimestamp = lastSavedframe.getTimeStamp();
    
                try {
    
                        yuvIplImage.getByteBuffer().put(lastSavedframe.getFrameBytesData());
    
                        videoRecorder.setTimestamp(lastSavedframe.getTimeStamp());
    
                        videoRecorder.record(yuvIplImage);
    
                    } catch (com.googlecode.javacv.FrameRecorder.Exception e) {
    
                        e.printStackTrace();
    
                    }
    
            }
    
            lastSavedframe = new SavedFrames(data,frameTimeStamp);
    
        }

  • High quality screen capture using ffmpeg on wayland [closed]

    27 novembre 2024, par Charlie Benger-Stevenson

    Running hyprland/wayland on arch.

    


    I want a reasonable quality (for say youtube) screen capture.

    


    ffmpeg -device /dev/dri/card1 -re -f kmsgrab -i - -vf 'hwmap=derive_device=vaapi,hwdownload,format=bgr0' -s 1920x1080 -c:v mpeg2video -b:v 1M -t 5  ~/Recordings/screencap.avi


    


    This should set a bitrate of 1M but the output is super blocky with a much lower bitrate than specified by the b:v flag.

    


    What am I doing wrong ?

    fate/pixfmts : extend the high bit depth test

    Also test 8bit formats, and try bitdepth conversion paths.
