Dave <[email protected]> added the comment: I've done a bit more research and had a look through the libswcaler source. Changing the swscaler to use anything other than bicubic seems to fix the problem. For example, adding "-sws_flags gauss" to the command line produces an acceptable output.
It would be nice to fix bicubic as that's the best setting for quality and speed, but in the meantime a workaround to use a different setting might be good..? ____________________________________________________ FFmpeg issue tracker <[email protected]> <https://roundup.ffmpeg.org/roundup/ffmpeg/issue675> ____________________________________________________
