vrecord pipe error with DVCPRO ERR=141

Hi There,

I am running into an issue with vrecord trying to transfer some DVCPRO tapes. I am using a MacBook Pro with an M1 chip that is running on Monterey 12.6.5. The deck being used is a DVCPRO AJ-D250. I have swapped out cables and other decks of the same model but keep getting an error right when the recording begins.

avftl seems to be working, but I think there may be an issue with FFmpeg. I did notice that the version of FFmpeg I have installed on my computer is v6. However, vrecord (version 2023-08-07) seems to be utilizing FFmpeg version 5.1.2. Not sure if this is contributing to what is going on.

```
$ vrecord -e
And place logs at /Users/tothba/Desktop too.
