  • Using ffmpeg for an Overlay [closed]

    4 juillet 2022, par Complete Savage

    I have a video thats a random amount long (it changes each time i run the project) (input.avi) (16:9 ratio)
Then i have another video that is around 10 seconds (this is fixed) (underlay.avi) (9:16 ratio)
I want to have underlay.avi under the input.avi and down about 1/3 so it looks like this :

    


    image

    


    Note that top part is also part of the underlay.avi

  • avutil/csp : add EOTF function definitions

    avutil/csp : add EOTF function definitions

    The existing av_csp_trc_func_from_id() mostly implements the OETF, except for
    
PQ. As such, we are currently missing a precise definition of an ITU-R EOTF.
    
Introduce the new functions av_csp_itu_eotf() and av_csp_itu_eotf_inv(), to fill
    
this void. Note that this is not possible in all cases, e.g. AVCOL_TRC_LOG which
    
has no corresponding EOTF definition in any ITU-R standard.
    

    Note that we cannot implement the proper HLG and SMPTE 428 OOTFs without access
    
to all three color channels, because they are not independent per channel. As a
    
result, we need to define them on double[3] instead of double (*func)(double).
