stream_lavf: warn if protocol not found

Browse Source 
If ffmpeg returns AVERROR_PROTOCOL_NOT_FOUND, print a warning that
ffmpeg should be compiled with network support. Note that stream_lavf.c
itself includes a whitelist of directly supported ffmpeg protocols, so
it can't happen that a completely unknown/madeup protocol triggers
this message. (Unless the ffmpeg:// or lavf:// prefixes are used.)
