    hwcontext_vaapi : Do not assume that sw_format is transferable

    Drivers can support a format for surfaces without also supporting it for
    
images, so we can't assume that sw_format is usable for transfer.  This
    
would previously hit an assert in cases where it isn't.

  • Hardware decoding using vaapi [on hold]

    15 août 2017, par Orient

    I am trying to replicate hardware decoding using vaapi. My ultimate goal is to get an OpenGL texture wich I whant to get from a vasurface buffer.

    I took as a base https://github.com/gbeauchesne/ffvademo/tree/master/src
    which looks less intimidating than other examples. My initial understanding was that packets were somehow rendered to surfaces (render targets) and at the same time got converted. But it looks like the loop after some nested calls boils down to avcodec_decode_video2 (app_decode_frame -> ffva_decoder_get_frame -> decoder_get_frame -> decoder_run -> decode_packet -> avcodec_decode_video2), which in turn would call codec->decode. So it resembles the way decoding is done on CPU.

    Could anybody explain why this whoud be considered hw decoding ?

    avcodec/nvenc : fix segfault in intra-only mode

    In intra-only mode, frameIntervalP is 0, which means the frame
    
data array is smaller than the number of surfaces.
    

    Together with using the wrong size on deallocation of the
    
frame_data_array, this lead to a crash.
