  • FFMPEG Incredibly Slow On Windows Server 2016

    1er août 2019, par Ben Gardner

    I have a t2.small (2GB RAM, 1 vCPU) Amazon EC2 instance running a process using FFMPEG. It runs just fine ( 30 fps) on my computer (i7, 12GB RAM), but at around 2 fps on the server. Here’s the command :

    rescale_command = f'ffmpeg -i {srcVideo} -filter_complex \"scale={owidth}:{oheight}, setsar=1:1, pad={dim[0]}:{dim[1]}:{oofx}:{oofy}\" {destVideo}'

    I’ve tried uninstalling and reinstalling ffmpeg/ffprobe

    Edited per llogan’s request, I’ve also discovered that it’s relatively speedy towards the beginning (I’m rescaling 100 times over the course of the program) and slows down towards the end.

    It utilizes 100% of the CPU even from the beginning, though.

    Example command/output :
    ffmpeg -i media/8-1-2019/hi/dl-107.mp4 -filter_complex "scale=607:1080, setsar=1:1, pad=1920:1080:656:0" media/8-1-2019/hi/sl-107.mp4

  • Anomalie #4369 (En cours) : YQL n’est plus actif

    7 août 2019, par Ybbet SPIP

    Bonjour tout le monde,

    J’ai envoyé un message sur la liste SPIP-Dev. Je crée un ticket pour traçabilité.

    SPIP offre depuis la boucle DATA la source YQL. Cf. code ici : https://core.spip.net/projects/spip/repository/entry/spip/ecrire/iterateur/data.php#L642
    Malheureusement, le service est fermé depuis le 3 janvier 2019. cf. https://news.ycombinator.com/item?id=18785255

    Je n’ai pas trouvé de solutions alternatives équivalentes en ligne. Que du Desktop "freemium" quand une solution existe.
    Il existe https://vespa.ai/ qui est à installer sur une machine.
    Autre élément trouvé https://www.pipes.digital/
    Je ne suis pas sûr qu’on retrouve une souplesse telle que l’était YQL.

    Bien à vous,

  • syncing a video file with audio using ffmpeg is returning a video without audio

    31 juillet 2019, par abbood

    When I attempt to sync a .mov video with an .m4a audio file using ffmpeg like so

    ffmpeg -ss 00:00:2 -i test.m4a  -i test.mov -c:v copy -c:a aac -strict experimental output.mp4

    it works like a charm. But right now I’ve recorded a usability test video using adobe XD, and it returned an .mp4 (MPEG-4) video and I manually recorded the audio using quicktimre returning a .m4a audio file.

    Trying to merge them using ffmpeg is returning a video without any audio :

    ffmpeg -i video.mp4  -i audio.m4a -c:v copy -c:a aac -strict experimental output.mp4
