  • ffmpeg : Too many bits per frame requested

    5 mai 2015, par nurma

    Sometimes there is an issue when i try to convert to mp4 using ffmpeg. I’m getting issue Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height.

    This is the command :

     ffmpeg -y -i input.mp4 -i watermark.png -filter_complex 'scale=-2:360,overlay=(main_w-overlay_w)-20:(main_h-overlay_h)-20' -codec:v libx264 -profile:v main -preset slow -b:v 300k -maxrate 300k -bufsize 600k -threads 0 -codec:a aac -strict experimental -b:a 128k -crf 20 output.mp4 1> output.log 2>&1

    Here the error log :

  • FFMPEG : custom sequence input images

    31 juillet 2018, par Dmitriy Puchkov

    I created a video from a set of images.

    The command look like :

    ffmpeg -i bg.jpeg -i img_%d.png -filter_complex overlay=5:H-h-5[b]-shortest testvid.mp4

    Problem :

    The input -i img_%d.png means img_0.png, img_1.png, img_2.png, ...

    But I have custom sequence like this : {img_0.png, img_1.png, img_1.png, img_2.png, img_1.png, img5.png, img_4.png}

    Question :

    Can I put my image sequence into input of ffmpeg ?

    Updated

    cmd :

    ffmpeg -i bg.jpeg -f concat -fflags +genpts -i test.txt -filter_complex overlay=5:H-h-5 -shortest testvid.mp4

    output :

  • How to speedup image processing (e.g. resizing, jpeg compress, encode) using ffmpeg command line utility from python on windows

    28 mars 2020, par MSD Paul

    I am running ffmpeg commands to downsizing and jpeg compression of a 4K image using command prompt on windows 10. But its taking a long time. To downsize, jpeg compress and finally encode to a video file it takes more than 500 ms.

    I can’t do the processing on images on batch but I have tried -hwaccel and -threads option (also -loglevel quiet for suppressing the logs being printed) in order to speedup the ffmpeg processing. Can someone please guide me towards how can I possibly speedup the ffmpeg command processing.

    Is it possible to pass the image files already read into memory using read() API to the ffmpeg command ?

    Please also let me know if there exists any other possible speedup techniques.
