[FFmpeg-devel] libavfilter scale problem
Fri Feb 26 12:58:17 CET 2010
Not sure whether resurrecting this thread is correct or whether i should
have started something new, but...
i think the changes Vitor made to vf_transpose and vf_rotate (were there
others too?) to prevent them from working with slices has introduced a bug
when the affected filter is not the last filter in the chain.
for example, this works as expected:-
ffmpeg -t 2 -i source.m2ts -vfilters "hflip,vflip,rotate=35" output.mp4
however, change the filter order like this:-
ffmpeg -t 2 -i source.m2ts -vfilters "rotate=35,hflip,vflip" output.mp4
crashes ffmpeg (on win32 with an accessviolationexception).
