[FFmpeg-devel] [PATCH 2/4] avcodec: add option to export video coding info

["Timothée Regaud" <timothee.informatique@regaud-chapuy.fr>]

From: Timothee Regaud <timothee.informatique@regaud-chapuy.fr>

Adds the AV_CODEC_EXPORT_DATA_VIDEO_CODING_INFO flag and the corresponding video_coding_info option to the options table, allowing users to enable this feature.
