[FFmpeg-devel] [PATCH 10/11] avformat/oggparsevorbis: Use AV_DICT_DONT_STRDUP_VAL to avoid av_strdup

[Andreas Rheinhardt]

This will likely also fix CID 1452427, a false positive resulting from
Coverity thinking that av_dict_set() automatically frees its key and
value parameters (even without the AV_DICT_DONT_STRDUP_* flags).

(AV_DICT_APPEND and AV_DICT_DONT_STRDUP_VAL are compatible with each
other since a8c5b455, so we can reset this flag here. It has originally
been removed in 0dc66553 when appending was added.)
