  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.

  • FFmpeg RTSP crash

    19 septembre 2016, par bot1131357

    I am trying to rtsp stream between two consoles on my computer.

    On console 1 I have :

    ffmpeg -rtbufsize 100M -re -f dshow -s 320x240 -i video="BisonCam, NB Pro" -r 10 -an -f rtsp -rtsp_transport tcp rtsp://127.0.0.1:8554/demo

    On console 2 I have :

    ffplay -rtsp_flags listen -i rtsp://127.0.0.1:8554/demo

    When I run execute both commands, my webcam LED lights up. But then immediately after ffmpeg crashes. Has anyone encountered the same thing ? I could really use some help here.

    This is my ffmpeg configuration on a Windows 10 machine :

Use -h to get full help or, even better, run 'man ffmpeg'

    Update

    I tried to stream from a video file, just to be sure that the issue is not related to the webcam.

    #Console 1
    
ffmpeg -i out.mp4 -f rtsp -rtsp_transport tcp rtsp://localhost:8888/live.sdp
    

    
#Console 2
    
ffplay -rtsp_flags listen rtsp://localhost:8888/live.sdp?tcp

    The output for both consoles are as follows :

    The same crash happened with ffmpeg.exe, and ffplay continued waiting for data. I tried the same commands on a Linux virtual machine, and it worked fine.

    Any ideas ?

    After building my own ffmpeg using the --enable-debug flag, I’m back at it again. Still getting the same error though. Any ideas ? At this point, it seems like there’s something wrong with my computer settings.

  • FFmpeg using png with tranparency and exclusion blending mode

    27 août 2016, par moorej

    I’m trying to use the exclusion blending mode to blend together a video and a png with transparency. I’ve looked around quite a bit but I can’t find a solution that works for me. Here’s the ffmpeg command :

    ffmpeg -i movie.mkv -i text_white_bg_trans.png -filter_complex\
    
  "[1:v]setsar=sar=1,format=rgba[txt]; [0:v]format=rgba[mo]; [mo][txt]blend=all_mode='exclusion'"  out_exclusion.mkv

    Edit : and the console output :

    Edit : Here’s a frame from the output.

    The output video is B&W rather than the original color (not sure why). The rectangle in the image is located where there is a block of text on a png with a transparent background. The png is the same size as the video.

    I’m expecting something more like this :
    enter image description here

    @Mulvya suggestion fixed the issue with color but I’m still seeing some problems with transparency being handled. I’m attaching a few different images below that each create different problems. All created in Photoshop CC (therein may lie the problem).

    A transparent background with a separate text layer that is then exported by Save->png, Photoshop appears to merge these two layers but differently than when "merge layers" is chosen before export. The exported image looks like the B&W image I posted above but with color.

    The in the second I merge the layers before exporting. It appears the entire image is treated as white.

    In the third I draw "hello" on a transparent layer with a "soft" brush using different grays then export. Transparent areas are rendered as white, gray or translucent areas opaque or with a strange dithering "effect."

    It seems I’m moving outside the realm of StackOverflow, but I’m not sure where this post would be better suited.

  • HTTP Livestreaming with ffmpeg

    25 août 2016, par Hugo14453

    Some context : I have an MKV file, I am attempting to stream it to http://localhost:8090/test.flv as an flv file.

    The stream begins and then immediately ends.

    The command I am using is :

    sudo ffmpeg -re -i input.mkv -c:v libx264 -maxrate 1000k -bufsize 2000k -an -bsf:v h264_mp4toannexb -g 50 http://localhost:8090/test.flv

    A breakdown of what I believe these options do incase this post becomes useful for someone else :

    sudo

    Run as root

    ffmpeg

    The stream command thingy

    -re

    Stream in real-time

    -i input.mkv

    Input option and path to input file

    -c:v libx264

    Use codec libx264 for conversion

    -maxrate 1000k -bufsize 2000k

    No idea, some options for conversion, seems to help

    -an -bsf:v h264_mp4toannexb

    Audio options I think, not sure really. Also seems to help

    -g 50

    Still no idea, maybe frame rateframerateframerateframerate ?

    http://localhost:8090/test.flv

    Output using http protocol to localhost on port 8090 as a file called test.flv

    Anyway the actual issue I have is that it begins to stream for about a second and then immediately ends.

    The mpeg command result :
