inference_realesrgan_video.py error

[Ashore-lz]

I get an error when I reason about the video
command：python inference_realesrgan_video.py -n realesr-animevideov3 -i inputs/video/onepiece_demo.mp4 -s 2 --suffix outx2
error：[concat @ 0x12eeb00] Impossible to open 'results/onepiece_demo_out_tmp_videos/000.mp4'
results/onepiece_demo_vidlist.txt: No such file or directory

1.Try to download FFmpeg from https://www.gyan.dev/ffmpeg/builds/ ,and configure environment variables
2.run pip install ffmpeg-python
Hope it helps you :)

hi could you solve this?

Check whether you have torch with gpu support.
torch.cuda.is_available()
should return True.
I have a PR which fixes these issues, but using cpu only pytorch is very slow.

I'm having the same issue on Debian 11 with a nVidia 1660:

[concat @ 0x55fb14d692c0] Impossible to open 'results/onepiece_demo_out_tmp_videos/000.mp4' results/onepiece_demo_vidlist.txt: No such file or directory

ffmpeg version 4.3.5-0+deb11u1
Python 3.9.2
Modules:
ffmpeg==1.4
ffmpeg-python==0.2.0

torch.cuda.is_available() returns True

UPDATE:

Ok, so I changed my command from
python inference_realesrgan_video.py -i inputs/video/onepiece_demo.mp4 -n weights/realesr-animevideov3 -s 2 --suffix outx2 --num_process_per_gpu 2
to just
python inference_realesrgan_video.py -i inputs/video/onepiece_demo.mp4 -n realesr-animevideov3 -s 2 --suffix outx2 --num_process_per_gpu 2
and it seems to run ??

UPDATE 2:
Ok, it runs, but get stuck after this message:
av_interleaved_write_frame(): Broken pipe Error writing trailer of pipe:: Broken pipe would it be related?

UPDATE 3:

The Broken Pipe error seems to have happened because the VM ran out of memory. Increasing the memory or decreasing --num_process_per_gpu solved this problem.

UPDATE 4:

More testing suggest that slow storage and higher --num_process_per_gpu may cause the problem of No such file or directory. Also, a trailing / in file path will result in incorrect path sent to ffmpeg. Possible solution might be:

if args.output.endswith('/'): args.output = args.output[:-1]

Hello,

I recently encountered a similar issue, and I was able to resolve it by converting the mkv file to an mp4 file. Though it doesn't seem like this would directly fix your problem with the example video, it does suggest that the issue might be related to the libraries that ffmpeg was compiled with.

Here's the ffmpeg command I used to convert the mkv file to mp4:
ffmpeg -i input.mkv output.mp4
