From 00d0934fcedad8e6418b066ab89552659271db00 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Tue, 17 Mar 2020 23:13:05 +0100 Subject: [PATCH] avformat/webmdashenc: Don't use custom option for bitexactness The WebM DASH Manifest muxer can write manifests for live streams and these contain an entry that depends on the time the manifest is written; an AVOption to make the output reproducible has been added for tests. But this is unnecessary, as there already is a method for reproducible output: The AVFMT_FLAG_BITEXACT-flag of the AVFormatContext. Therefore this commit removes the custom option. Given that the description of said option contained "private option - users should never set this" and that it was not documented in muxers.texi, no deprecation period for this option seemed necessary. The commands of the FATE-tests for this muxer have been changed to no longer use this option.
