Title: [BUG] SRT subtitles displayed with wrong size
Post by: bogdanbz on November 16, 2023, 03:01:21 pm: Copy the text below in a srt file and use it with any video file in JRiver and in MPC.

JRiver displays the subtitles extremely tiny and with a large space between the lines, while MPC displays them properly.

~~What's more, JRiver displays the first and second subtitle lines at the same time, while the line timestamps are not overlapping, and it should first display line 1, and later line 2.~~

Later edit: the first and second line are displayed at the right time, my mistake; it's the line spacing that's wrong

Code: [Select]
1 00:00:02,080 --> 00:00:07,070 This is the first line of text to be displayed, 2 00:00:07,070 --> 00:00:08,520 and this is the second line of text. 3 00:00:14,590 --> 00:00:15,780 Thank you for looking at this issue! 4 00:00:31,450 --> 00:00:35,930 All things considered, this is something that should not look like this. 5 00:00:36,800 --> 00:00:38,080 MPC's internal subtitle renderer seems to handle this better.

SRT format doesn't seem to clearly define this, but it seems to be commonly assumed that "24" means 24px, not 24%. MC is also ignoring an explicit size="24px" tag, so I think you're right - should be fixed.

Post by: Hendrik on January 04, 2024, 12:23:00 pm: MC calculates the line spacing on the default text size, which isn't great for this. I'll look into this.

I'll also add support for explicit 24px/24pt instructions, as well as set SRT to interpret no unit as a pixel/point size, not a percentage. I can't change that globally as all sorts of things would fall apart.

SRT subtitles rarely specify a size, as its often better to just let the player figure it out.

Post by: Hendrik on January 11, 2024, 09:44:20 am: I fixed both the size handling as well as the spacing for the upcoming MC32. I'll also take a look at the other subtitle topics soon.
