    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Not able to change the program number for the video

    17 May 2018, by 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!

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

    10 July 2024, by 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. 


    


  • problem with linking macos library - version number on wrong place

    21 November 2019, by freedev

    This is it seems a stupid problem.

    Basically I’m building a python wheel, I have everything and the build already works on linux.
    But when I’m trying to build on macos I have this strange error:

    *** No rule to make target `/usr/local/Cellar/ffmpeg/4.2.1_2/lib/libavutil.dylib.56’

    Looking at /usr/local/Cellar/ffmpeg/4.2.1_2/lib/ I see exists a file named:

    /usr/local/Cellar/ffmpeg/4.2.1_2/lib/libavutil.56.dylib

    You see, the difference is only in the name. The former has the number at end, the latter has the number in the middle.

    If I create a symbolic link from libavutil.56.dylib to libavutil.dylib.56 the linking complete successfully.

    Does anyone know why this is happening and how to solve this problem?
