IDR with opengop

Reported by: Mista_D Owned by:
Priority: wish Component: avcodec
Version: unspecified Keywords: libx264

Blocking: Reproduced by developer: no
Analyzed by developer: no


Can not insert IDR frames using "-force_key_frame" command while using "open_gop" with libx264.

ffmpeg -i input -x264-params open_gop=1 -force_key_frames 10,20 output.mp4
FFmpeg version: 3.1.2

The "forced" key frames are not IDR, nor scene_change detected ones, while later is expected.

Bounty $50 USD using paypal or WU for qpfile FFmpeg patch.
Expires Sept 6th, 2016

Thank you!

Maybe add a "I-frame_type" feature to "force_key_frame" option if possible?
