As far as I can tell from testing with various source files (mostly DVR-MS
or WTV, with the occasional MPG) it seems that the still that is grabbed is
always the resolution of the source video, irrespective of aspect ratio.
544x576 video in 4:3 or 16:9 gives 544x576 still whereas 2.1.5 would have
scaled it to 768x576 or 1024x576.
704x576 in either aspect ratio gives width of 704 instead of 768 or 1024;
likewise 720x576 always gives 720 instead of 768 or 1024.
I've not found any examples of a higher resolution video file producing a
lower resolution still (eg 704x576 producing 544x576 still).
Looks as if older versions of VLC automatically scaled the width to give a
still of the correct aspect ratio based on the height, whereas 2.2.x gives
you the native resolution of the source, with no scaling.
The issue has been reported on TRAC so hopefully it will be fixed one day -
but I won't hold my breath because a bug that I raised well over a year ago
(subtitles not displayed for WTV files, only for TS files produced from the
WTV) has still not been fixed and the TRAC report seems to have stalled with
speculation about the possible cause but still no firm investigation and
plan to resolve. I bumped the thread a month or so ago but there's been no
response so it's probably never going to be fixed.
Let's hope they fix the three regressions that I'm aware of:
- lack of scaling of stills
- corrupted timestamp in filename of still
- severely corrupted picture playback of DVR-MS (but not WTV or MPG) files
All these have been introduced since 2.1.5.
