#136 Messed up bitrate, time, speed and est. size values during encoding

[Peter]

Hello, I would like to report some strange behavior winth latest version of ffmpeg batch 3.2.6 and ffmpeg 8.0.1. I am still using the same presets and it worked perfectly until now. I had older version of ffmpeg.exe, so I downloaded newest stable ffmpeg 8.0.1 x64 from gyan.dev web, and put it into ffmpeg batch folder.

From ffmpeg site, official download links going to gyan.dev website and BtBn's github. So far, I always downloaded from gyan, idk if there is any significant diefference between those builds.

Now, when converting into h265 through GPU, ffmpeg batch reports insane values during process. Like, that bitrate is in hundreds Mb's, estimated size of encoded file is like 60GB (from like 2GB h264 mkv used as source), and remaining time is like 30hrs. Encoding speed is reported as 0.0279x / 180fps, which is nonsense too. Progress bar sometimes stay at 0.3% for most of the time of encoding, then jump to 50%, then to an end.

But, encoding duration takes the same time as always and encoded file size is okay too, in relation to my encoding settings. Just that progress, time, speed and bitrate values are messed up during encoding.

Release notes for ffmpeg batch are "tested with ffmpeg 8.0", so probably this is some problem of ffmpeg. Maybe they change something in 8.0.1?
