Hi all

As ive already backported and somewhat tested release/4.3 i intend to
make the next point release from that and after that next is
3.4 (because its the supported branch that is longest without a release)

like always, please backport things if you want something backported
please test, if you want something tested
and tell me if theres anything i need to know (like waiting for something)

thx

Hi! it would be nice if my bug fix

   avformat/libopenmpt: fix seeking weirdness

was backported to 6.1.3 and 7.0.3 (dunno about 5.1.7 as i haven't checked
if libopenmpt even exists there). not sure how that would work from my side

I just checked, and it seems that my patch can be backported as far back
as 3.2 (it cannot be backported to 3.1 or earlier because libopenmpt demuxer
does not exist there, 3.2 code is similar enough to today's code)

On 5.0 and earlier there is a merge conflict because a line of code near my
change had changed a little bit so here's a version of the patch with conflict
solved for convenience, for later versions (including 5.1) just rebase ecef5f9e1f

i haven't tested the patch on top of anything older than 6.1.1 so i don't know
if the seeking problems exist there, but the patch shouldn't break anything
either as it doesn't depend on any APIs that were changed between 3.2 and latest

Subject: [PATCH] avformat/libopenmpt: fix seeking weirdness

- proper pts for packets. leaving it blank leaves it up for guessing,
  but the guess doesn't take seeking into account, causing weirdness.

- clamp to 0 when seeking to negative ts. libopenmpt docs are unclear on
  this but not doing this causes an immediate EOF when seeking backwards
  to the beginning in mpv.

- only set song duration and packet pts when they are non-negative and
  in int64 range. NaNs count as out of range. this isn't a fix for any
  specific issue but might be helpful still, and shouldn't break
  anything.
