Author: Mans Rullgard <[email protected]> Committer: Mans Rullgard <[email protected]> Date: Tue Nov 29 18:38:02 2011 +0000 Do not memcpy raw video frames when using null muxer Commit 035af99 made avconv always call an encoder when using the null muxer. While useful for 2-pass encodes, it inadvertently caused an extra memcpy of raw frames when decoding only. This hack restores the old behaviour when only decoding while allowing use of the null muxer with encoded streams as well.
