Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: externals Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: whyameye (whyameye) Assigned to: Nobody/Anonymous (nobody) Summary: pdp_mix giving imperfect copy for crossfade=1 (no mmx)

Initial Comment: when crossfade is set to 1 for [pdp_mix], outlet should return exact copy of middle inlet. Instead [pdp_mix] still tries to mix the left and middle inlet, resulting in slight degradation of the resulting video. Consequently, a feedback loop connecting [pdp_mix] outlet to its middle inlet through a [pdp_del] with crossfade set to 1 will eventually result in a video that is completely black.

This patch adds a trivial copy from the middle inlet to the outlet if the crossfade is set to 1. This patch works for the portable (no mmx) version of the code. The mmx version of the code has the same flaw and the patch for this will be submitted separately.
