Sure, here.

Excellent, thanks a lot for reviewing the feature!
LGTM

Set applied.
Suggest doing any non-performance-critical development (like this) with asan enabled in future; it doesn't slow things down very much and makes it easier to catch and fix leaks as you go along.
Thanks,

It's a good idea - I didn't have it on the record anymore after the pause.
In the past, it had often caused trouble with MSVC (/fsanitize=address), so
we had it only in a Linux CI - which this work didn't go through 😊
I'll check it out, maybe MS have made some progress with it.
Thanks for the suggestion and the patches,
sw

I've run with the mermaidhtml output a bit as well. The output looks nice but there are many asan errors, mostly from lost string alloctions - see below.
I had a look at fixing these, but the object lifetime model appears more complex than I could straightforwardly divine - it's not obvious when any given object can be freed. I suggest that you with your greater understanding would be better placed to fix these.
Thanks,
- Mark

Hi Mark,
of course that's on me to fix, and yes - the string handling is really
a bit tricky. At some point I had introduced av_strdup() everywhere after I
realized that it's too hard to track which strings might stem from literals
and which are not, so it's very plausible that I missed some cleanup.
I've enabled ASAN just an hour ago and currently digging into other errors
it is showing like that one:
==11668==ERROR: AddressSanitizer: new-delete-type-mismatch on 0x122d130b6580 in thread T0:
object passed to delete has wrong type:

Maybe a mismatch of lib and include..
Anyway, I'm on it, thanks a lot for the output,

Hi Mark,
I think I got all of them covered now, patches sent.
While hunting those leaks, I noticed a lot of leaks around QSV hardware
acceleration, is that known and do you see these as well? I hope it doesn't
go back to my original code for QSV D3D11..
Thanks
sw
Command was something like:
-init_hw_device d3d11va=d1:2 -init_hw_device qsv@d1 -hwaccel qsv -c:v h264_qsv -i in.mkv -filter_complex "[0:0]scale_qsv=w=512:h=256[f1_out0]" -map [f1_out0] -c:v hevc_qsv out1.mkv
