From cb92b4bd835c005816d97a2c8106a53af43173f0 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Sun, 11 Feb 2024 20:17:31 +0100 Subject: [PATCH] avutil/hwcontext: Clarify documentation of AVHWFramesContext.hwctx Correct the names of the format-specific headers (not hwframe_*.h) and clarify that the user shall ignore this field if there is no public context associated with it. In particular, this allows to use this field for the private context alone if there is no public context. This can't break conforming API users, because they always have to live with the possibility that a new public context has been introduced.
