Hello, This patch adds multiple reference frames support (part of Video Codec SDK 9.1). It adds "nb_ref_frames" CLI option to set number of reference frames. Possible values:
* auto - let encoder decide (default value). * [0;7] - set value by hand. 0 is equal to auto. Usage example: ffmpeg -i big_buck_bunny_1080p_h264.mov -c:v hevc_nvenc -frames:v 128 -nb_ref_frames auto -bf 2 -y big_buck_bunny_1080p_nb_auto.h265 ffmpeg -i big_buck_bunny_1080p_h264.mov -c:v h264_nvenc -frames:v 128 -nb_ref_frames 1 -y big_buck_bunny_1080p_nb_1.h264 Actual number of reference frames will be determined by encoder, but it will not exceed value of "nb_ref_frames" option. -- BR, Roman Arzumanyan ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
