Hello, can someone enlighten me as to why this gives error -22
"invalid argument" which results in bad dst image pointers?

AVFrame * frame = av_frame_alloc();

}
Int size =
av_image_get_buffer_size(pCodecContext->pix_fmt,pCodecContext->width,pCodecContext->height,0);
auto picture_src = (uint8_t*)av_malloc(sizeof(uint8_t) * size);

You might want to set the alignment to 1, just in case.
sws_scale(img_convert_ctx,
frame->data,frame->linesize,0,pCodecContext->height,frame->data,frame->linesize);
----------------------------------------------------
What is it that i'm not understanding?
You are using sws_scale to decode to the same pointers it is reading
from. That's more likely your problem.
