  • 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" (...)

  • How to close colons in timecodes for OS X bash

    1er septembre 2015, par Tandy Freeman

    I’m trying to generate videos using ffmpeg that display a burnt in timecode of the source video. I’m using a bash script in OS X.
    video 1 has a starting timecode of 09:59:30:00

    In order to use the drawtext filter in ffmpeg, I need to close the colons, as they are used to delimit the filter.

    They need to be in this format in the script timecode='00\:00\:00\:00' and they will ultimately show up like this in the actual terminal window : timecode='\''00\:00\:00\:00'\''

    Is there some way to transform the values stored in the $timecode variable, using sed or awk, or something similar ?

    I’m using ffprobe to generate the timecode and adding it as a variable

    $ timecode=($(ffprobe -v error -show_entries format_tags=timecode -of default=noprint_wrappers=1:nokey=1 "$1" ))
    
$ echo $timecode
    
09:59:30:00

    When I add the variable $timecode in this fashion to my script :

    ffmpeg -i "$1" -c:v libx264 -crf 23 -pix_fmt yuv420p -vf drawtext="fontsize=45":"fontfile=/Library/Fonts/Arial\ Black.ttf:fontcolor=white:timecode="$timecode":rate=$framerate:boxcolor=0x000000AA:box=1:x=360-text_w/2:y=480" ""$mezzanine"/"$filenoext"_PRORES.mov"

    the timecode shows up without anything closed when I use bash -x :

    + ffmpeg -i /Users/kieranoleary/Downloads/AS11_DPP_HD_OEM_SAMPLE_136_1.mxf -c:v libx264 -crf 23 -pix_fmt yuv420p -vf 'drawtext=fontsize=45:fontfile=/Library/Fonts/Arial\ Black.ttf:fontcolor=white:timecode=09:59:30:00:rate=25/1:boxcolor=0x000000AA:box=1:x=360-text_w/2:y=480' /Users/kieranoleary/Downloads/AS11_DPP_HD_OEM_SAMPLE_136_1/mezzanine/AS11_DPP_HD_OEM_SAMPLE_136_1_PRORES.mov

    and I get the following error :

    [Parsed_drawtext_0 @ 0x7f9dc242e360] Both text and text file provided. Please provide only one
    
[AVFilterGraph @ 0x7f9dc242e4e0] Error initializing filter 'drawtext' with args 'fontsize=45:fontfile=/Library/Fonts/Arial Black.ttf:fontcolor=white:timecode=09:59:30:00:rate=25/1:boxcolor=0x000000 A:box=1:x=360-text_w/2:y=480'

    Merge commit '3303f86467efa99f23c670707f5be094cc9ce547'

    * commit '3303f86467efa99f23c670707f5be094cc9ce547' :
    
  nvenc : Remove qmin and qmax constraints for nvenc vbr
    

    [10:06:59 CEST] <BtbN> jamrial, 3303f86467 is a no-op. NV_ENC_PARAMS_RC_2_PASS_VBR is a deprecated rc mode(http://git.videolan.org/?p=ffmpeg.git;a=blob;f=compat/nvenc/nvEncodeAPI.h;h=c3a829421282d5f22f82fc285723f13eb660f053;hb=HEAD#l268).
    
[10:07:14 CEST] <BtbN> And the first hunk with qmin/qmax was applied to ffmpeg quite a while ago already.
    
[10:07:49 CEST] <BtbN> In a slightly different fashion, but with the same effect
    
[10:07:58 CEST] <BtbN> Came as a patch from nvidia iirc
