[FFmpeg-devel] [PATCH] url_write not defined if muxers are disabled

[Gianluigi Tiesi]

Hi,
I've noticed that url_write in avio.c is referenced even if
muxers are not enabled, but it's not compiled in.

The patch allows to return EIO if someone calls url_fopen/fdopen
in write mode while muxers are disabled


Regards
