  • Récupération d’informations sur le site maître à l’installation d’une instance

    26 novembre 2010, par

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • Reduce the number of chunk-stream files when converting to mpeg-dash

    10 juillet 2024, par NSS

    My command : ffmpeg -i input_file.mp4 -c:v libx264 -c:a aac -b:v 6000k -b:a 192k -f dash output.mpd

    


    When I convert a mpeg4 file into mpeg-dash, ffmpeg generates a certain number of .m4s files (e.g chunk-stream0-00003.m4s) of different sizes. If I convert a really large file ffmpeg can generate thousands of files like that. My questions are :

    


      

    1. how can I set that no .m4s file is more than 5MB ? I need this to stream a smaller chunk faster over HTTP.

      2. 


    2. how can I reduce the number of generated .m4s files ? I need this because the custom storage has a limit on files in a directory.

      3. 


    


  • Not able to change the program number for the video

    17 mai 2018, par C.B. Akshay Kumar

    I have been trying to change the program number of a particular .ts file using FFmpeg without any success. I saw the documentation and it mentions to use the -program option. But, I am not able to add the streams as I desire. Here’s the program information for the stream that I possess currently :

    Input #0, mpegts, from 'output_2_without_pgm_num.ts':
    
  Duration: 00:01:49.92, start: 1.400000, bitrate: 1816 kb/s
    
  Program 1
    
    Metadata:
    
  service_name    : Service01
    
  service_provider: FFmpeg
    
Stream #0:0[0x100]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, progressive), 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 90k tbn, 50 tbc
    
Stream #0:1[0x101](ger): Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, fltp, 384 kb/s (clean effects)
    
Stream #0:2[0x102](eng): Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, fltp, 384 kb/s (clean effects)
    
Stream #0:3[0x103](ger): Subtitle: dvb_teletext ([6][0][0][0] / 0x0006)

    Now, I want to change the program number from 1 to 22. Any idea how I could do that ? I have tried using -program option, but I can’t add streams 2 and 3 to the newly created .ts file.

    Thanks in advance !

  • Overlaying frame number with ffmpeg [duplicate]

    30 mars 2024, par DMagma

    This should be simple but it is giving me fits and I haven't been able to find this specific problem. I am trying to overlay the frame number on a set of videos but my ffmpeg command string is ignoring any text overlay that has anything to do with a frame number. For example, these produce the correct overlay

    


    "-vf drawtext=fontfile='Arial.ttf': text='TEST': fontsize=30: fontcolor=yellow@1.0:x=(w-text_w-15):y=15" 
"-vf drawtext=fontfile='Arial.ttf': text='%camera%': fontsize=30: fontcolor=yellow@1.0:x=(w-text_w-15):y=15" 
"-vf drawtext=fontfile='Arial.ttf': text='%vname%': fontsize=30: fontcolor=yellow@1.0:x=(w-text_w-15):y=15" 


    


    but these all ignore the "text" input and instead overlay "fontsize=30" or "start_number=1" to the frames

    


    "-vf drawtext=fontfile='Arial.ttf': text=%{n}: fontsize=30: fontcolor=yellow@1.0:x=(w-text_w-15):y=15" 
"-vf drawtext=fontfile='Arial.ttf': text='%{n}': fontsize=30: fontcolor=yellow@1.0:x=(w-text_w-15):y=15" 
"-vf drawtext=fontfile='Arial.ttf': text='Frame %{frame_num}': start_number=1: fontsize=30: fontcolor=yellow@1.0:x=(w-text_w-15):y=15" 


    


    I am at a loss as to why it is not properly identifying or using the frame number.

    


    I have tried multiple variations such as those shown above including swapping the order of the inputs to no effect.
