From 22aa71d4da37a4ad2b0d28deeace64b57aa2ef50 Mon Sep 17 00:00:00 2001 From: James Almer Date: Fri, 7 Feb 2025 00:04:25 -0300 Subject: [PATCH] avcodec/libtheora: fix setting keyframe_mask t_info.keyframe_granule_shift is set to the library default of 6, which is ok for gop sizes up to 63. Since there's apparently no way to query the updated value after having forced a gop value with TH_ENCCTL_SET_KEYFRAME_FREQUENCY_FORCE, calculate it manually instead. Fixes ticket #11454.
