From bd0b661183d2a57ab13cacaa2aac31c645444d61 Mon Sep 17 00:00:00 2001 From: wm4 Date: Sat, 12 Jul 2014 19:16:53 +0200 Subject: cache_file: fix operation if stream size is unknown Happens when playing from a pipe. Note that seeking forward doesn't work. It would be possible to create a workaround for that by reading and skipping data until the target position is reached (and writing the skipped data into the cache file), but I'm not sure about that. Fixes #928.
