[FFmpeg-devel] How to enable png encoder

[Chenyang Zhu]

Hi

This is a strange problem.

If configuring ffmpeg with -disable-muxers -disable-demuxers
-disable-encoders -disable-decoders -enable-encoder=png, png encoder will
not be built in.

Howerver, if I configured with -disable-muxers -disable-demuxers
-disable-encoders  -enable-encoder=png, png encoder will be built in.

It seems that png encoder has something to do with some decoders.

 

How to fix this problem? I don't want all the decoders to be built in.

Thansks!
