[FFmpeg-devel] [PATCH] avformat: disable seeking on FIFOs/named pipes

[Martin Sliwka]

Patch is addition to my previous patch 
(https://lists.ffmpeg.org/pipermail/ffmpeg-cvslog/2012-June/051590.html) 
and disables seeking on FIFOs/named pipes by setting 
URLContext::is_streamed (same as pipe: protocol does for stdin/stdout pipes)
