  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • Using multiple variables in system call in c++ ?

    19 juillet 2017, par Patrick

    I am writing this little programm that reads its settings from a file and proceeds to give those settings to another program. In this case its ffmpeg.

    The first part is working properly. Now I have the settings stored in strings to give them to ffmpeg. However I cannot find a way to make it work with the variables in a system call.

    system ("start binaries\\ffmpeg_64.exe -i \"input\\testvideo.mp4\" -c:v libx264 -preset veryslow  -crf 32 -c:a aac -b:a 96k -threads 9 \"output\\testvideo_out.mp4\"");

    The line above is working properly. Now when i add the strings (preset,threads, crf, inputfile) that i got from the settingsfile is does not work anymore.

     system ("start binaries\\ffmpeg_64.exe -i \"input\\"+inputfile+".mp4\" -c:v libx264 -preset "+preset+"  -crf "+crf+" -c:a aac -b:a 96k -threads "+threads+" \"output\\"+inputfile+preset+crf".mp4\"");

    The Error I am getting : [Error] cannot convert ’std::basic_string’ to ’const char*’ for argument ’1’ to ’int system(const char*)’

    Any ideas ?

  • Find the streaming url source of an online streaming tv station to record with ffmepg

    20 mars 2016, par AHC

    I am trying to look into the javascript streaming source of the following site http://www.aztv.az/canli/aztv-canli.htm to capture the url and to record it using ffmpeg.

    My goal is to get something like this running :

    ffmpeg -i rtsp://XXX.XXX.XXX.XXX:XXX/live.sdp -acodec copy -vcodec copy c:/test_recording.mp4

    I don’t know what protocol this website uses, rtsp, rtmp, http, etc.
    Could you please help me to resolve this ?
    I tried to look into the .js file in the source of the page, but it is a bit complicated to figure it out. here is the js script.

  • how to automatically oversample and downsample when using filters ?

    4 juin 2021, par Yue Wang

    I am researching avfilters. Say I have an audio with sample rate s, and bit depth d,

    


    What I want to do is to write a graph that

    


      

    • upsample s by 4x, and set precision to 64bit float

      • 


    • apply some biquad filters with 64bit precision

      • 


    • downsample by 4x back to s, and set bit depth back to d.

      • 


    


    The reason to oversample is to get better filtering result by antialiasing, and the reason to downsample is to stream using the original source format.

    


    I don't know if there's way that I can do it automatically in the graph.

    


    ashowinfo could print out the sample rate, but seems there's no way to use the value later in the pipeline.

    


    asoftclip has a oversample factor. but it's not available in other filters.
