Error occurred when executing VHS_VideoCombine

[chlowden]

Hello I am running comfyui for sdv tests on a rocky linux 8.9 machine. I have downloaded all the latest versions and reinstalled the VHS_VideoCombine twice but I continue to get the error below. ffmpeg is installed and so is imageio-ffmpeg but I continue to get the error below

Thank you `

The GIF export works.

The only thing that comes to mind is that the system version of ffmpeg is installed is significantly old. Currently, the code will always prefer the system version of ffmpeg if it is available.

Does the problem persist if you force usage of the bundled imageio-ffmpeg python by either

• Uninstalling the system version of ffmpeg or
• Editing line 27 of videohelpersuite/nodes.py from if ffmpeg_path is None to if True

[chlowden]

Uninstalling ffmpeg is not really an option on my machine ... But changing the line:

ffmpeg_path = shutil.which("ffmpeg") if True:

worked. Thank you very much

Wonderful. I'll add some code on the development branch to allow for easier configuration of this.

A more long term solution that doesn't require fiddling is something I've been considering, but don't currently have a good answer for.

[chlowden]

Thank you for all your hard work and good luck.

If you also want to install ffmpeg properly, I found the solution.

1- Download the latest version from gyan.dev (https://www.gyan.dev/ffmpeg/builds/ffmpeg-git-full.7z) 2- Extract file and rename "ffmpeg" 3- Cut the "ffmpeg" folder into C:\ (or any disk name) 4- open cmd and run. --> setx /m PATH "C:\ffmpeg\bin;%PATH%"

finally you can verify that it is installed properly from the terminal: --> ffmpeg -version

good luck! (w)

Hey I'm experiencing this same issue. Running on a Runpod template, Jupyter notebook. Reinstalling ffmpeg and the edits to nodes.py didn't solve for me, unless I did something wrong. I edited line 27 to just If True

I'm getting the following error:

_Error occurred when executing VHS_VideoCombine:

An error occured in the ffmpeg subprocess: Unrecognized option 'crf'. Error splitting the argument list: Option not found

File "/workspace/ComfyUI/execution.py", line 153, in recursive_execute output_data, output_ui = get_output_data(obj, input_data_all) File "/workspace/ComfyUI/execution.py", line 83, in get_output_data return_values = map_node_over_list(obj, input_data_all, obj.FUNCTION, allow_interrupt=True) File "/workspace/ComfyUI/execution.py", line 76, in map_node_over_list results.append(getattr(obj, func)(**slice_dict(input_data_all, i))) File "/workspace/ComfyUI/custom_nodes/ComfyUI-VideoHelperSuite/videohelpersuite/nodes.py", line 211, in combinevideo raise Exception("An error occured in the ffmpeg subprocess:\n" \

Any idea what could be the problem?

[AustinMroz]

I've got a rough guess: Double check that imageio-ffmpeg is actually installed.

If it isn't, then an edge case in the quick fix here will cause a warning to be displayed at startup (Failed to import imageio_ffmpeg), but will keep using the seemingly incompatible system ffmpeg afterwards.

You could also add a print(ffmpeg_path) on line 34 and check that the resultant path is from imageio-ffmpeg such as:

ComfyUI/venv-lin/lib/python3.11/site-packages/imageio_ffmpeg/binaries/ffmpeg-linux64-v4.2.2

Hi have same issue, the node is highlighted in red. Have someone solution? thanks in advance!

测试可行，

1. 修改该插件ComfyUI/custom_nodes/ComfyUI-VideoHelperSuite目录下的nodes.py
2. 搜索# Use ffmpeg to save a video，将下方的if ffmpeg_path is None 修改为if ffmpeg_path is True，保存退出，重新启动
