"Error Muxing a Packet" Upon Updating Vrecord

[lavidtech-1]

Hi All,

We were successfully using the V2023-03-01 version of Vrecord on an Intel Mac and decided to update to the V2023-08-07 earlier today.

Upon updating, we ran into "Error Muxing a Packet" and were unable to capture the video. After a quick search, I found a similar issue existed in Vrecord a long time ago and the solution was to not close the window, but use a durationand after the duration ends, the video would capture correctly.

I tested this and it worked, but I don't understand why the new version caused this issue. Below is the readout from capturing the tape:Last login: Wed Nov 1 15:30:47 on ttys000 1545media@LAVTS-MAC-CAPTURE-05 ~ % vrecord Starting the vrecord GUI.

Any ideas on how to fix this so we can close the window upon capture without the error? Thanks in advance for your help.

We're experiencing the same behavior over here at MARMIA. We ran into trouble after upgrading to the latest version of vrecord earlier this week, just like you.

[dericed]

yup, I confirmed it's a regression since https://github.com/amiaopensource/homebrew-amiaos/commit/cad790c4247f6ef372123617d4a6443fdc5ef48a. Fixing it now.

[dericed]

Hi @lavidtech-1 and @siobhan-cernugelj, please run brew upgrade. This should downgrade ffmpegdecklink from 6.0 to 5.1.2 which should fix the error.

[bturkus]

I'm having an issue rolling back; any ideas?

disabling htmlpages seemed to do the trick, but I fear I may have messed up one computer but futzing around with brew edit (ffmpegdecklink). I've tried uninstalling and reinstalling everything, untapping and retapping amiaos, but now no matter what I do I'm getting this error:

@bturkus, have you taken the advice of brew doctor?

[siobhan-cernugelj]

Hi @lavidtech-1 and @siobhan-cernugelj, please run brew upgrade. This should downgrade ffmpegdecklink from 6.0 to 5.1.2 which should fix the error.

Unfortunately, we're still experiencing the same behavior. It doesn't look like ffmpegdecklink was actually downgraded.

[privatezero]

@siobhan-cernugelj not sure if it will fix it on your end, but did you try running a brew remove --ignore-dependencies ffmpegdecklink and then reinstalling it from scratch? (Maybe a brew cleanup between those commands might help)

[retokromer]

(Possibly even a brew cleanup --prune=all.)

[FolkHistory]

I've also had this issue but can confirm that brew upgrade solved it for me.

[lavidtech-1]

Hi Folks, can confirm on our end that brew upgrade worked for us and it allows us to close the window without corrupting the file.

[siobhan-cernugelj]

@siobhan-cernugelj not sure if it will fix it on your end, but did you try running a brew remove --ignore-dependencies ffmpegdecklink and then reinstalling it from scratch? (Maybe a brew cleanup between those commands might help)

I went ahead and ran brew upgrade again. For whatever reason, trying the same thing twice actually resolved the issue the second time around.

Everything seemed to be working fine again, but we were still seeing an alert about ffmpegdecklink at launch. I uninstalled it, ran brew cleanup, and reinstalled. This appears to have taken care of the problem, whatever it was.
