From d6604b29ef544793479d7fb4e05ef6622bb3e534 Mon Sep 17 00:00:00 2001 From: Vittorio Giovara Date: Wed, 15 Jul 2015 18:41:20 +0100 Subject: Gather all coded_frame allocations and free functions to a single place Allocating coded_frame is what most encoders do anyway, so it makes sense to always allocate and free it in a single place. Moreover a lot of encoders freed the frame with av_freep() instead of the correct API av_frame_free(). This bring uniformity to encoder behaviour and prevents applications from erroneusly accessing this field when not allocated. Additionally this helps isolating encoders that export information with coded_frame, and heavily simplifies its deprecation.
