 Summary of the bug:
 I have an MPEG-TS file ("test.ts" with "test.ass" sub file) that I wanted
 to test AV1 encoding on. This seems to be an obscure error regarding
 subtitles, since the only thing I could find on Google was another post
 suggesting that I downgrade to 4.1.4 (searching for arib_caption brings up
 more relevant results such as
 https://github.com/nkoriyama/aribb24/issues/10).

 This is the error log when I try the following command:
 https://pastebin.com/5hYsi8uU

 Full console output for the file:
 https://pastebin.com/gbkgGeU4

 Oddly enough, this doesn't occur on the sample file I outputted using the
 following:
 {{{
 ffmpeg -ss 00:08:00 -i test.ts -ss 00:01:00 -t 00:01:00 -c copy
 testclip.ts
 }}}

 Since the error doesn't seem to occur on the clipped sample, I haven't
 uploaded it. The original video file is 5GB. If you want, I can upload
 that.

 How to reproduce:
 {{{
 ffmpeg -i test.ts -c:v libaom-av1 -crf 15 -b:v 0 -strict experimental
 av1_15test.mkv
 }}}

 {{{
 ffmpeg -i test.ts -c:v libx265 -crf 15 -c:a aac -b:a 320k test.mkv
 }}}
