[Ffmpeg-devel] undefined symbol: sws_getCachedContext

[Tobias Marx]

Thanks for the following hint:

./configure --enable-swscaler && make dep && make

it says:

p15201909:/home/ffmpeg/ffmpeg # ./configure --enable-swscaler && make dep && make

The software scaler is under GPL and --enable-gpl is not specified.

???

Specified where?
