Trying to get this to work. Have a Quadro P1000 card, all the cuda checks pass but in execution, it fails and defaults to software. Log file attached, here’s the error I’m finding: [mpeg2video @ 0000026adf73eb00] decoder->cvdl->cuvidCreateDecoder(&decoder->decoder, params) failed -> CUDA_ERROR_INV…

Actually the error returned by the graphics drivers is related to decoding and not encoding. It’s still using the hardware encoder: 2019-05-15T07:11:59 MCEBuddy.AppWrapper.FFmpeg → Stream #0:0: Video: hevc (hevc_nvenc) (Main) (hev1 / 0x31766568), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], q=-1–1, …

Thanks for taking a look at it Goose. I’ll just leave it alone then since it actually seems to be operating correctly.

When the program starts, it goes like crazy using handbrake, but errors out and then reverts to ffmpeg which is much slower. I’ve attached two conversion logs highligh…

Either the source video has corrupted data or your video driver has a bug and isn’t able to handle it: 2020-03-30T23:52:19 MCEBuddy.AppWrapper.Handbrake → Encoding: task 1 of 1, 16.18 % (386.94 fps, avg 353.10 fps, ETA 00h06m30s) 2020-03-30T23:52:20 MCEBuddy.AppWrapper.Handbrake → [23:52:20] 1048…

Thanks for taking a look. So, I recently had to rebuild my server and when I reinstalled and rebuilt my MCE profiles, I unchecked “select best audio” and checked “multichannel audio”. I can’t explain it, but I haven’t had the issue since. I offer that in case anyone else is having a similar issue. …

Hello! I’m getting similar error messages when using this command: ffmpeg -re -hwaccel cuvid -hwaccel_output_format cuda -extra_hw_frames 10 -i rtmp://xxxxxxxxx -map 0 -c:v h264_nvenc -b:v 2M -maxrate 2M -qmin 34 -qmax 51 -g 60 -bf 3 -b_ref_mode middle -bufsize 1M -c:a aac -ar 44100 -ac 1 -flush_p…

Why are you using hwaccel for decoding. Most likely it’ll just slow down your conversion due to bus and memory transfer overhead.

Hi Goose. I got 30 live channels running at the same time, server has 2 Quadro P5000 GPUs, I’m using hwaccel for decoding to avoid overload the CPUs. Cheers!

You’ll likely slow it down and consume more CPU by enabling decoding for the reasons mentioned above when using other software features (like audio encoding, filters etc). Try not using it.

謝謝你幫我看，Goose。既然它實際上似乎運作正常，那我就先不管它了。
