This is the offending line. If you assign the same extradata buffer to
both structures, it'll be free'ed twice.
avcodec_parameters_from_context will already copy the extradata, I would
recommend to move that line after opening the encoder, then there is no
need to manually touch it, and nothing bad happens.
