I'm trying to get VDA work with ffmpeg on Mac, and there is no document
other than the claim "it can use VDA."
There is no sample, no document, no anything!!
the only thing I could find is this,
AVCodec* aCodecVda = avcodec_find_decoder_by_name ("h264_vda");
avcodec_open2 (theCodecCtx, aCodecVda, NULL);
and this doesn't work at all, avcodec_open2 gives me kVDADecoderDecoderFailedErr
after looking at this example:
I realized that I need to pass kVDADecoderConfiguration_avcCData with
what's avcCData? how do I get it? there is no document at all.
this is too frustrating!
