branch qsv-2.8.1 can't set IdrInterval for hevc encoder #11

Closed andrewmabc closed 6 years ago

andrewmabc commented 6 years ago

There is no way to set IdrInterval for hevc encoder like h264.

For example,

/usr/local/bin/ffmpeg -i input.mp4 -acodec libfdk_aac -ac 2 -b:a 32k -vcodec hevc_qsv -s 640x360 -b:v 400k -g 250 -f mp4 output.mp4

There is only one key frame in output.mp4

And there is no 'IdrInterval' option for hevc_qsv, like h264_qsv.

It has been supported by https://github.com/FFmpeg/FFmpeg. Could you try https://github.com/FFmpeg/FFmpeg/commit/077011b5af2b3150efc52a9b58f5ef9bb0235087 and https://github.com/FFmpeg/FFmpeg/commit/98afe3fb71afd4a18009924aaba56bc577bbd400 ?
