Timeouts can happen with various conditions, big, slow to decode files is one of them. Most of the time those timeouts are not really important to "fix". While they may show some issues like we currently have with audio EOF #14427 for ao-null-untimed. Most of the reports are completely not important and we should focus on other topics. Ignore the timeouts during file playback, note that this will still report any timeouts that happen in other conditions. 5 seconds of playback should cover most of interesting mpv code, even for strange samples. This will likely be reverted at some point in the future, but let first stabilize the OSS-Fuzz, without dozens of bogus timeouts.
