  • How to use GPU to accelerate the processing speed of ffmpeg filter ?

    20 septembre 2020, par Zedd W

    According to NVIDIA's developer website, you can use GPU to speed up the rendering of the ffmpeg filter.

    


    


    Create high-performance end-to-end hardware-accelerated video
processing, 1:N encoding and 1:N transcoding pipeline using built-in > filters in FFmpeg

    


    Ability to add your own custom high-performance CUDA filters using
the shared CUDA context implementation in FFmpeg

    


    


    The problem I am having now is how to use the GPU to speed up multiple ffmpeg filter processing ?

    


    For example :

    


    ffmpeg -loop 1 -i dog.jpg -filter_complex "scale=iw*4:-1,zoompan=z='zoom+0.002':x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':s=720x960" -pix_fmt yuv420p -vcodec libx264 -preset ultrafast -y -r:v 25 -t 5 -crf 28 dog.mp4


    


  • Online RTMP radio with Python + FFmpeg + Nginx : unable to have a continuous output stream

    2 décembre 2023, par Igor Longo

    Thinking about an application similar to an online radio, I'm trying to transmit a sequence of audio files chosen by the user, where he chooses which file will be played in the sequence, sufficiently in advance for the reproduction not to be muted. I'm using FFmpeg in a Python script and an RTMP server running Nginx.
The problem is that interrupting the transmission between one file and another appears to be breaking the transmission on output. Sometimes files are skipped and other times it simply crashes for the client.

    


    I have already tried transmitting the sequence of files in real time, using '-re', and I have also tried not using '-re', creating a custom queue manager in Python with the intention of trying to keep only 'n' files in the server buffer .
Below is an excerpt of the code :

    


    ffmpeg_command = [
'ffmpeg',
'-loglevel', 'warning',
# '-re', # read input at native frame rate
'-i', file_path,
'-c:a', 'aac',
'-ar', '44100',
'-bufsize', '1024k',
'-af', 'atempo=1.0',
'-b:a', '128k',
'-f', 'flv',
'-flvflags', 'no_duration_filesize',
rtmp_url # server url
]
subprocess.run(ffmpeg_command, check=True)

    


    Any tips on how I can resolve this ?
