Create Slice Scale Extrude I want to split image into two slices (height 2) and scale (yuv >rgb) them separately using ws scale (may be in different threads). for example. auto * ctx = avformat alloc context(); const char *src filename = file name.c str(); auto res = avformat open input(&ctx, src filename, nullptr, nullptr); if (res < 0) return nullptr; return ctx;. Scale the image slice in srcslice and put the resulting scaled slice in the image in dst. assumes planar yuv to be in yuv order instead of yvu. definition at line 912 of file swscale.c. referenced by blur (), dotest (), ff scale image (), filter frame (), main (), queue picture (), scale slice (), sws scale (), and wrap ().
9 Slice Scaling New Figma Community Scale source data from src and write the output to dst. this function can be used directly on an allocated context, without setting up any frame properties or calling sws init context(). The code is designed as a destination line pull architecture. that is, for each output line the vertical scaler pulls lines from a ring buffer. when the ring buffer does not contain the wanted line, then it is pulled from the input slice through the input converter and horizontal scaler. Scale the image slice in srcslice and put the resulting scaled slice in the image in dst. a slice is a sequence of consecutive rows in an image. slices have to be provided in sequential order, either in top bottom or bottom top order. if slices are provided in non sequential order the behavior of the function is undefined. I have some legacy code that was written against an old version of ffmpeg and i need to update it to use the latest api's. there is some code that does cropping that currently looks like this: imgresamplecontext* r context = img resample full init (dst width, dst height, src linesize, src height, crop.top, crop.bottom, crop.left, crop.right, 0.

Scale the image slice in srcslice and put the resulting scaled slice in the image in dst. more scale source data from src and write the output to dst. more initialize the scaling process for a given pair of source destination frames. more. Merging of operations (e.g. reading yuv input and yuv2rgb conversion to prevent memory stores) where possible and where it gains significant speed it may well be possible for the "fast" and "scaled" codepaths to be mixed, although this obviously needs more thought. Scale the image slice in srcslice and put the resulting scaled slice in the image in dst. more. Sws scale(img convert ctx, avframeyuv >data, avframeyuv >linesize, 0, srcy, avframergb >data, avframergb >linesize); draws the resulting frame with windows bitblt.
