    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.

  • vp8 : change mv_{min,max}.{x,y} type to int

    8 juin 2015, par Andreas Cadhalpun
    vp8 : change mv_min,max.x,y type to int

    If one of the dimensions is larger than 8176, s->mb_width or
    
s->mb_height is larger than 511, leading to an int16_t overflow of
    
s->mv_max.x,y. This then causes av_clip to be called with amin > amax.
    

    Changing the type to int avoids the overflow and has no negative
    
effect, because s->mv_max is only used in clamp_mv for clipping.
    
Since mv_max.x,y is positive and mv_min.x,y negative, av_clip can’t
    
increase the absolute value. The input to av_clip is an int16_t, and
    
thus the output fits into int16_t as well.
    

    For additional safety, s->mv_min,max.x,y are clipped to int16_t range
    
before use.

  • GStreamer force decodebin2 output type

    6 septembre 2014, par user975326

    I’m trying to write a program in C which replicates the pipeline :

    gst-launch -v filesrc location="bbb.mp4" ! decodebin2 ! ffmpegcolorspace ! autovideosink

    DecodeBin2 has a dynamic pad and I’ve attached a callback to handle its creation. I am unable to link it to ffmpegcolorspace however because the pad capability is always video/quicktime. I would like it to be video/x-raw-yuv or something else which is compatible with ffmpegcolorspace.

    Is this possible to force/select the output type of decodebin2 ?

    Thanks.

    EDIT : Please do not recommend playbin. I’m trying to learn how how to make pipelines.
