Re: FW: Bug in File Meta Source: Repeat does not work for detached headers

Hi Adrian,

thanks for the report! Yes, if you can, please create a ticket! If you want, you could
throw your recording and your playback flow graphs into a zip file and attach that to your
issue text, that makes reproduction 100% reliable.

This is excellent bug reporting, by the way, thank you very much!

Just as perspective:

We have two other issues, https://github.com/gnuradio/gnuradio/issues/3516 and
https://github.com/gnuradio/gnuradio/issues/5568 , concerning the metadata file sink. Both
of them use the non-detached header, so they seem to be different from yours.

Best,
Marcus

I really hope that the older two versions are actually filtered and I'm not spamming the mailing list. If I accidentally did, please accept my apologies - first time interacting with a mailing list.
