  • MediaSPIP : Modification des droits de création d’objets et de publication définitive

    11 novembre 2010, par

    Par défaut, MediaSPIP permet de créer 5 types d’objets.
    Toujours par défaut les droits de création et de publication définitive de ces objets sont réservés aux administrateurs, mais ils sont bien entendu configurables par les webmestres.
    Ces droits sont ainsi bloqués pour plusieurs raisons : parce que le fait d’autoriser à publier doit être la volonté du webmestre pas de l’ensemble de la plateforme et donc ne pas être un choix par défaut ; parce qu’avoir un compte peut servir à autre choses également, (...)

  • dnn : add layer pad which is equivalent to tf.pad

    29 juillet 2019, par Guo, Yejun
    dnn : add layer pad which is equivalent to tf.pad

    the reason to add this layer first is that vf_sr uses it in its
    
tensorflow model, and the next plan is to update the python script
    
to convert tf.pad into native model.

  • DivX audio not decoded on DVD player

    8 août 2019, par Shaul

    Moved to https://video.stackexchange.com/questions/28225/divx-audio-not-decoded-on-dvd-player

    I am converting MP4 movie into AVI/DivX format. I plan to copy the AVI to a USB memory stick and plug it into my DVD player. My player is a Pioneer 3052 that supports USB input.

    I convert the file using ffmpeg without error messages. The output file is played correctly on my computer, including audio. I use "Movies & TVs" and "DIVX Player" for testing.

    When I try running it on my Pioneer the video and the subtitles are ok but there’s no audio. I know that there’s no issues with the hardware because videos converted with "FreeMake Video converter" do play audio.

    My command line is :

    .\ffmpeg.exe  "-i INFILE -c:v mpeg4 -vtag xvid -qscale:v 3 -c:a libmp3lame  -vf "scale=720:576:force_original_aspect_ratio=decrease,pad=720:576:(ow-iw)/2:(oh-ih)/2","subtitles=f=SRTFILE:charenc=ISO-8859-8:force_style=PrimaryColour=&amp;H0000FFFF,Fontsize=16" OUTFILE

    I also experimented with -b:a 192k, -b:a 96k and -qscale:a 4 all leading to the same results.

    I wander what else to try.
    I add the report produced by ffprobe (for the output file) :

  • Applying same filter_complex many times before output [duplicate]

    19 août 2019, par Fabián

    This question already has an answer here :

    It’s not a duplicate. This is about using filter_complex, not -vf.

    In my video there’s an object that has shades of yellow (more orange-like) and a solid yellow as background.

    I need to output all frames into a png sequence, using a color key filter to replace the yellow from the background :

    ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.125:0[ckout]" -map "[ckout]" colorkey-%d.png

    This removes the specific color, but leaves some pints behind, and some items are yellow-themed, so blending value is a no-no for this scenario.

    I need to get rid of 4 specific yellow-colors from the frames : 0xfff31b, 0xfae56b, 0xfaec46 and 0xeee2a0, and I plan to run the same filter for specific colors before getting the final result.

    So first I tried this :

    ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.4:0[ckout1];[0:v]colorkey=0xfae56b:0.4:0[ckout2];[0:v]colorkey=0xfaec46:0.4:0[ckout3];[0:v]colorkey=0xeee2a0:0.4:0[ckout4]" -map "[ckout4]" colorkeyrefined-%d.png

    Then this :

    ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xfae56b:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xfaec46:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xeee2a0:0.4:0[ckout]" -map "[ckout]" colorkeyrefined-%d.png

    But both display the same error :

    Filter colorkey has an unconnected output.

    Is there a way to apply the colorkey feature 4 times (with the mentioned values) in one go ?
