Add option to allow HEVC on devices that can't encode B frames #28

Closed e-dong closed 3 weeks ago

I tried running the encoder benchmark on my linux laptop and I ran into this error:

[yuv4mpegpipe @ 0x5613eff6e6c0] Stream #0: not enough frames to estimate rate; consider increasing probesize
Input #0, yuv4mpegpipe, from '1080-120.y4m':
  Duration: 00:00:19.86, start: 0.000000, bitrate: 2985989 kb/s
  Stream #0:0: Video: rawvideo (I420 / 0x30323449), yuv420p(tv, progressive), 1920x1080, 120 fps, 120 tbr, 120 tbn
Stream mapping:
  Stream #0:0 -> #0:0 (rawvideo (native) -> hevc (hevc_nvenc))
Press [q] to stop, [?] for help
[hevc_nvenc @ 0x5613eff71a00] B frames as references are not supported
[hevc_nvenc @ 0x5613eff71a00] No capable devices found

According to https://github.com/GyanD/codexffmpeg/issues/78, adding -b_ref_mode 0 fixes this issue.

Applied it to this!

    pub fn get_benchmark_settings(&self) -> String {
        return format!("-preset p1 -tune ll -profile:v {} -rc cbr -cbr true -gpu {} -b_ref_mode 0", self.profiles.get(0).unwrap(), self.gpu);
    }

Boom, it's working!

Giving ffmpeg a change to let go of the decode file, hang tight...

To fix permutor-cli I had to add this

args.push_str(" -b_ref_mode 0");

To impl NvencSettings

Ooo nice! That'd be an easy fix 👍
