Nevermind all that previous nonsense. I misunderstood the intended use of avpicture_fill and that was the source of a great deal of my confusion. Now I can ask the right question:
*How do I get the raw image buffer (located in a uint8_t array called data) into the AVFrame? * * * I've looked at the API a great deal today and yesterday, and I don't see a clear way to accomplish this. -Neil On Tue, Apr 23, 2013 at 10:22 AM, Neil Menne <[email protected]>wrote: > //begin relevant code here > mSwsContext = sws_getContext(input_width, > input_height, > input_pixel_format, > output_width, > output_height, > output_pixel_format, > SWS_BICUBIC, > NULL, > NULL, > NULL); > > AVPicture input_picture; > avpicture_alloc(&input_picture, > input_pixel_format, //AV_PIX_FMT_BGR24 > input_width, //656 > input_height); //354 > > ret = avpicture_fill(&input_picture, > data, > input_pixel_format, > input_width, > input_height); > > AVPicture output_picture; > avpicture_alloc(&output_picture, > output_pixel_format, > output_width, > output_height); > > if (mSwsContext != NULL) > { > ret = sws_scale(mSwsContext, > input_picture.data, > input_picture.linesize, > 0, > input_height, > output_picture.data, > output_picture.linesize); > > //ret here is always 0 > } > > //etc.... > > > On Tue, Apr 23, 2013 at 10:21 AM, Neil Menne < > [email protected]> wrote: > >> I'm trying to convert a raw image that I receive as a unsigned character >> array.
