  • Extract bytes of specific stream from mpegts file using ffmpeg

    2 novembre 2016, par MaMazav

    I have an mpeg-ts file with a single program. The program consists of some streams - one video stream and some metadata streams.

    I would like to extract a specific stream to a separate file. However the metadata is encoded using a codec that ffmpeg doesn’t know. I don’t really care about this - I just want to extract the data as bytes, without the mpeg-ts container headers. I tried to use codec "copy" but with no success.

    I tried the following :

        ffmpeg -i video.ts -map 0:1 -codec copy stream.txt

    But ffmpeg says :

        Unable to find a suitable output format for stream.txt

    The error above is only because ffmpeg doesn’t know how to output a text file. So I tried to output with "rawvideo" container :

        ffmpeg -i video.ts -map 0:1 -codec copy -f rawvideo stream.txt

    But :

        Cannot map stream #0:1 - unsupported type

    Just to ensure that I can extract a content of an unknown codec I tried the following :

        ffmpeg -i video.ts -map 0:1 -codec copy stream.ts

    But again :

        Cannot map stream #0:1 - unsupported type

    So my questions are :

    • Can I extract a byte stream of an unknown codec stream ? and how ?
    • How can I output the byte stream without any container ? Should I use the rawvideo ?

  • avutil/softfloat : Move av_sincos_sf() from header to c file

    avutil/softfloat : Move av_sincos_sf() from header to c file

    The function is quite big and trigonometric functions should not really
    
be used in speed critical code

  • h264 : move the DPB init/uninit to init_context()/free_context()

    5 avril 2015, par Anton Khirnov
    h264 : move the DPB init/uninit to init_context()/free_context()

    Currently, the DPB is initialized in alloc_tables() and uninitialized in
    
free_tables(), but those functions manage frame size-dependent
    
variables, so DPB management does not logically belong in there.
    

    Since we want the init/uninit to happen exactly once per the context
    
lifetime, init_context()/free_context() are the proper place for this
    
code.
