Could you add a rust demo ,how to use it in rust like ffmpeg rtsp and rtmp stream push?

thanks

Hi,
I clone the project, and add an api named insert_idr_frame(), to generate an IDR Frame.
The impl is adding av_opt_set(c->priv_data, "forced-idr", "1", 0); before avcodec_open2() , then set the picture type by encoder->frame->pict_type = AV_PICTURE_TYPE_I before avcodec_send_frame.
This worked at Nvidia card, but no use for AMD card, did you have any idea?

Thanks.

What license is this crate published under?

Encoding via Intel graphics is not properly supported on Ubuntu 22.04 and Windows 10 Since Linux uses va-api, Windows doesn't seem to support qsv yet, even if it's an extra. Is this intended?

The cpu used in the encoder is Intel N6005. IGPU has been used.

This crate looks fantastic! Any chance it will be published on crates.io?

Hi @21pages, I raise the issue in #8. But I guess you guy are too busy to cover a "closed" issue, so my additional questions were ignored. I re-open it again to get your attentions :D

I find the lib use VAAPI, and according to https://trac.ffmpeg.org/wiki/HWAccelIntro, Intel GPU have good support on VAAPI. Considering a lot devices running intel CPU with integrated GPU, I am curious why Intel GPU is seconded.
