From aa6360928efee8c3193b1862bb520fc66cb3ef1f Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Thu, 30 Sep 2021 05:33:25 +0200 Subject: [PATCH] avfilter/formats: Add function to create AVFilterFormats with one entry Most instances ff_add_formats() actually only ever add one format; this function can be used to simplify those callers.
