  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Using more than 2 NV_ENC at a time with FFMPEG

    29 décembre 2022, par lowcrawler

    I'm currently generating timelapse videos using a thread on my CPU with fluent-ffmpeg running on nodejs. It takes roughly 1 minute to generate a 10 second timelapse. I'm generating many at the same time (basically one per thread) such that I tend to get the best performance at 8 worker threads. ... overall system throughput is about one video per 12 seconds.

    


    GPU processing using h264_nvenc takes the single-thread time to about 3-4 seconds. Yippie ! I went out and bought some nVidia 1660's to take advantage.

    


    Unfortunately, when I go to generate the 3rd simultaneous video, I get "Conversion Failed !" error from FFMPEG.

    


    Some basic research seems to show you can only 2 at a time. Perhaps 3 with updated drivers.

    


    Is there a method around this ? Posts from here indicates this limit is artificial and can be worked around : https://www.techpowerup.com/268495/nvidia-silently-increases-geforce-nvenc-concurrent-sessions-limit-to-3

    


    Perhaps a way to use all the cuda/tensor/etc cores to render timelapse videos instead of just relying on the limited nv_enc ?

    


  • Time Overlay on RTMP Video Streaming Using FFMPEG

    7 août 2015, par Dipak D Desai

    I have used following command line to stream video and overlay the time and date on video.

      raspivid -t 0 -w $3  -h $4 -fps 15 -b 500000 -o - | ffmpeg -an -i -  -r 15 -vf drawtext="fontfile=/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans-Bold.ttf: text='%m/%d/%y \%T ':fontcolor=red@1.0: fontsize=15: x=20: y=170" -vcodec copy -tune zerolatency -b:v 200k -preset fast -crf 30 -maxrate 300k -bufsize 500k -f flv -metadata streamName=$2 $rtmpurl &

    I am able to stream video using above command but not get time and date text overlay on video.

    If any one have idea let me guide.

  • How do I join multiple glob inputs into a time lapse with ffmpeg ?

    14 octobre 2019, par jtanman

    I’m trying to combine image files from multiple directories into one combined time lapse using ffmpeg, but when running this code, only the first directory is used in the time lapse. How do I combine multiple glob inputs using ffmpeg ?

    ffmpeg -pattern_type glob -i "Time\ Lapse\ 11/*.JPG" \
    
-pattern_type glob -i "Burst\ Sequence\ 5/*.JPG" \
    
-pattern_type glob -i "Burst\ Sequence\ 6/*.JPG" \
    
-r 30 -c:v libx264 -crf 23 -preset fast -pix_fmt yuv420p tl11_combined.mp4

    I’ve tried using glob sequence which didn’t do anything, and I’ve tried various concat methods using a text file including directory names, but haven’t found the correct format so far. Thanks !
