  • Hardware acceleration of color conversion and scaling using QSV with ffmpeg, libav

    28 septembre 2023, par zerpico

    I used hardware decoding on an Intel processor using QuickSync based on this example.&#xA;https://github.com/FFmpeg/FFmpeg/blob/master/doc/examples/qsv_decode.c

    &#xA;

    Then I use sws_scale to color convert from NV12 to YUV420. But is there a way to use hardware acceleration for this too ?

    &#xA;

    some part of my code

    &#xA;

    //decoding frame&#xA;int32_t ret = avcodec_receive_frame(_context, _tmpFrame); //i got _tmpFrame->format == AV_PIX_FMT_QSV&#xA;&#xA;//retrieve data from GPU to CPU&#xA;av_hwframe_transfer_data(_decFrame, _tmpFrame, 0); //i got _decFrame->format == AV_PIX_FMT_NV12&#xA;&#xA;//...some code next&#xA;//init context&#xA;conversion = sws_getContext(_context->width, _context->height, AV_PIX_FMT_NV12,&#xA;                             _context->width,_context->height, AV_PIX_FMT_YUV420P,&#xA;                             SWS_FAST_BILINEAR, NULL,NULL,NULL);&#xA;&#xA;//convert frame  (is Intel QuickSync used here)?&#xA;int32_t out_height = sws_scale(conversion, src_data, src_stride, 0, src_height, dst_data, dst_stride);&#xA;
