  • Keeping control of your media in your hands

  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • Using FFmpeg with URL input causes SIGSEGV in AWS Lambda (Python runtime)

    26 mars, par Dave94

    I'm trying to implement a video converting solution on AWS Lambda following their article named Processing user-generated content using AWS Lambda and FFmpeg.
However when I run my command with subprocess.Popen() it returns -11 which translates to SIGSEGV (segmentation fault).
I've tried to process the video with the newest (4.3.1) static build from John Van Sickle's site as with the "official" ffmpeg-lambda-layer but it seems like it doesn't matter which one I use, the result is the same.

    


    If I download the video to the Lambda's /tmp directory and add this downloaded file as an input to FFmpeg it works correctly (with the same parameters). However I'm trying to prevent this as the /tmp directory's max. size is only 512 MB which is not quite enough for me.

    


    The relevant code which returns SIGSEGV :

    


    ffmpeg_cmd = '/opt/bin/ffmpeg -stream_loop -1 -i "' + s3_source_signed_url + '" -i /opt/bin/audio.mp3 -i /opt/bin/watermark.png -shortest -y -deinterlace -vcodec libx264 -pix_fmt yuv420p -preset veryfast -r 30 -g 60 -b:v 4500k -c:a copy -map 0:v:0 -map 1:a:0 -filter_complex scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:(ow-iw)/2:(oh-ih)/2,setsar=1,overlay=(W-w)/2:(H-h)/2,format=yuv420p -loglevel verbose -f flv -'
command1 = shlex.split(ffmpeg_cmd)
p1 = subprocess.Popen(command1, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = p1.communicate()
print(p1.returncode) #prints -11

    And that's the end of it. It should continue to do the processing until 00:04:02 as that's my audio's length but it stops here every time (approximately this is my video length).

    


    The relevant code which works correctly :

    


    ffmpeg_cmd = '/opt/bin/ffmpeg -stream_loop -1 -i "' + '/tmp/' + s3_source_key + '" -i /opt/bin/audio.mp3 -i /opt/bin/watermark.png -shortest -y -deinterlace -vcodec libx264 -pix_fmt yuv420p -preset veryfast -r 30 -g 60 -b:v 4500k -c:a copy -map 0:v:0 -map 1:a:0 -filter_complex scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:(ow-iw)/2:(oh-ih)/2,setsar=1,overlay=(W-w)/2:(H-h)/2,format=yuv420p -loglevel verbose -f flv -'
command1 = shlex.split(ffmpeg_cmd)
p1 = subprocess.Popen(command1, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = p1.communicate()
print(p1.returncode) #prints 0


    


    With this code it repeats the video as many times as it has to do to be as long as the audio.

    


    Both versions work correctly on my computer.

    


    This question is almost the same but in my case FFmpeg is able to access the signed URL.

    


  • ffmpeg nvdec not available when adding subtitles to mp4

    17 février 2019, par whatdoineed2do

    I have a mp4 video that I want to BURN-IN subtitles (from a .ass file and via -vf ass=/tmp/conf-notes.ass) with ffmpeg on a machine with a GTX1060 card however ffmpeg reports that it fails to create the NVDEC decoder.

    [h264 @ 0xcb9380] Error creating a NVDEC decoder: 1
    
[h264 @ 0xcb9380] Failed setup for format cuda: hwaccel initialisation returned error.

    The output file is generated ok but during the creation the CPU is used heavily (I assume for decode) - if I drop the -vf ass=/tmp/conf-notes.ass and perform an mp4->mp4 reencode there are no problems.

    I want to know what I am missing from my command to allow the GPU to perform the decode when an .ass file is added to the chain.

    $ ffmpeg -hwaccel cuvid -i 2019-01-conferance.mp4 -vf ass=/tmp/conf-notes.ass -c:a copy -preset llhq -rc vbr_hq -vb 2M -minrate 500k -maxrate 12M -c:v h264_nvenc export.mp4

  • FFMPEG build on Windows using MSVC - make fails
