  • fftools/ffmpeg_mux : distinguish between sync queue and muxer EOF

    9 février 2023, par Anton Khirnov
    fftools/ffmpeg_mux : distinguish between sync queue and muxer EOF

    Individual streams should be terminated in the former case, the whole
    
muxing process in the latter.

  • lavc/vorbisdec : use intermediate variables

    19 septembre 2022, par Rémi Denis-Courmont
    lavc/vorbisdec : use intermediate variables

    The compiler cannot infer that the two float vectors do not alias,
    
causing unnecessary extra loads and serialisation. This patch caches
    
the two input values in local variables so that compiler can optimise
    
individual loop iterations.

  • How to integrate Netflix audio isma and video ismv files into a single file ?

    25 juillet 2012, par Ωmega

    Having Netflix audio .isma file and video .ismv file, how can be those separate files be integrated into a single .mp4 or .flv file ? Is there some schema or algorithm that can be used to develop such a tool, or is there already a tool available ?

    I tried to use ffmpeg as follows :

    # ffmpeg -i in.isma -i in.ismv out.mp4

    Even there is no audio error shown in the above response, I was unable to convert the single audio .isma file into mp3 or other audio format file. I assume these isma/ismv files are somehow crypted or encoded in non-standard format. Below is a partial dump of audio file.
