video won't play with subtitles active

[PesoMemo]

Having a subtitle file causes some videos to not render. Video refuses to start.
DNDing a subtitle file to VLC sometimes causes VLC to stop rendering video and the progress bar races to the end and stops.
Same with vlsub download.

Some videos work with subs; some don't.
3.0.6 and 3.0.8 both have same issue.

Here's a message=2 printout of a DND of subs file onto video:

Your logs are not complete. Are you trying to play .ts files with .srt subtitles ?

Logs are incomplete because of 5000 char limit. I removed what I thought were the least useful, similar lines.
I'm playing .mp4 files with .srt subs. The .mp4 file was built from a .m3up file.

The playback only fails after adding the subs file into the mix - by same name at start or DnD or vlsub fetch.

You can use pastebin to upload more

I'm playing .mp4 files with .srt subs. The .mp4 file was built from a .m3up file.

Can you upload both files somewhere so that we can reproduce ?

Don't know what pastebin is.

Any suggestions as to where ? Never done before other than an upload form for various images.

The .m3up list could indeed be .ts segments. I wrote a Perl GUI to take a .m3u file and retrieve the segments (currently the segment URLs have to be full/complete URLs) to cat into a file and I didn't really look to see what the segs were. The result is a "H264 - MPEG-4 AVC (part 10) (h264)" file with ADTS audio.

Which means now the srt timestamps are not aligned to the mp4 ones.
No issue.

I mean.. if you googled what PasteBin was ;d

I thought it was something local to this site or I might have.

I've been having the same problem as Original Poster for months. I read through this thread and didn't see a solution to the problem (or at least, not one that seems to apply).

Since the problem first occurred, I upgraded my version of VLC but that still hasn't fixed the problem. For some reason if I try to use an SRT file for English Subs in virtually any scenario now, where in the past it would play with no issues, now the file won't play if I have the subtitles in the folder (and it's auto-detecting it) or if I select the sub manually. If I just play the regular file without subs - no issues.

I can get both the video and subs working with the default Windows 10 Movies & TVs app (although the sound quality seem to hiccup when this is done - very small breaks that interrupt the audio repeatedly while playing). But if I use Windows Media Player, it can't play the subs either (again, no problem playing the video file).

Exactly the same here
