Use mktemp instead.

First reported on BSD and Debian 10 (reproducible), apparently tied to some updated tool

Seen in HEVC contained in MPEG-TS

Version 1.12.3 breaks on FreeBSD due to the usage of GNU-specific extensions of expr, sed and an incompatible Bash RE.

As reported by Dirk Reiners (paraphrased)

When steps get too small they might round to 0 ⇒ infinite loop in compute_timecodes.

pyth_th() uses **, accepted by gawk but not mawk

Also Ubuntu uses mawk by default.

“Failed to capture frame (at second xxx.yyy)”

Known bug, reported by various users.

Only basename should be printed instead.

A great utilty... I’ve been using this for a couple of years now (it runs every night as a cron job).

I’ve been looking at cleaning up the output that cron captures from each of its commands and stores as a system email.

I’ve enabled the -Wc option to prevent coloured output. Mostly this works except near the start of the script when it says:
Settings from /home/danc/.vcs/vcs.conf:
bg_heading
This is still shown in green. Bug?

Currently the colour only stops after the option is found.

Here’s a patch against 1.13.2 for mistaken approximate size calculation.

Self-notes about the patch:

• More accurate rounding → Discarded. I went for rounding by excess
• Leading 0 in fractionary units was not present in the original → BUG
  Sample: Samsung HD sample, 1080pto720p version

Reported by Miya

When using mplayer as capturer and defining a number of captures, the produced number exceeds it by one (i.e. 21 instead of 20).

Unquotted grep pattern ^ID is problematic.
