A Crash

[zhang]

Hi,everyone:
I've met this issue for several weeks. When I recorded the desktop, I sometimes met a problem called" :
[ffmpeg muxer: 'simple_file_output'] os_process_pipe_write for info structure failed
13:17:48.091: [ffmpeg muxer: 'simple_file_output'] ffmpeg-mux: Error writing to 'H:/地震录制视频/2025-07-07_12-47-28.mp4', Invalid argument

13:17:48.091:

I've uploaded the file.

try swapping your video encoder to NVENC in settings>output and also changing your recording format to hybrid MP4.

 

[zhang]

But there is no NVENC in video encoder. There are only x264, AOM-AV1 and SVT-AV1 for choosing.

 

[zhang]

But there is hybrid MP4 for sure.

From your log it appears as if the video file is being written for some 10 minutes, then suddenly the OBS process isn't permitted to write any more. You're writing to a H: drive. It may be this drive has become defective and developed bad sectors. I recommend a hardware check and you changing to a different drive and try again.

...

The "os_process_pipe_write for info structure failed" in the middle of the file writing is definitely a hardware problem.
According to:

Recording Error: Stream Recording to External Hard Drive

OBS Version: 31.0.1 Windows 11 I've been sporadically getting the following error message when trying to record a stream to an external hard drive: An encoder error occurred while recording: Error writing to 'D:/{file path}', Invalid argument av_interleaved_write_frame failed: -1: Operation...

you may look for more error messages about the disk in the "Event Viewer" of Windows.

it doesn't show up because your driver is very out of date, you need to update it https://www.nvidia.com/en-us/drivers/details/247854/

that being said, as also mentioned in this thread it could be an issue with the drive you are recording to but I wanted to check these things first. if you're still having issues after using NVENC and hybrid MP4, you'd want to try recording directly to your C drive.

 

[zhang]

Thanks a lot, and the issue didn't appear again after I formatted the portable hard drive.

 

[prgmitchell]

I strongly recommend recording to an internal drive and moving the files to the portable after regardless, you're just asking for more issues recording directly to it.

 

[zhang]

OK.
