Downloading some episodes cannot be played

[ltsj]

When I download episode 6, it can't be played after the download is complete. But I downloaded episode 5 again and it played fine.

./crunchy archive -l ja-JP https://beta.crunchyroll.com/series/G5PHNM403/the-dawn-of-the-witch[S01E06] -v -g 5

And the file that cannot be played normally contains a German subtitle with an abnormal time，When I remove this subtitle file and remix the stream, the video can be played normally.

./crunchy download -r best https://beta.crunchyroll.com/series/G5PHNM403/the-dawn-of-the-witch[S01E06] -g 5

I tried downloading the .ts and it was fine. Seems to be a problem converting to .mkv

[ltsj]

I tested again when I use:

./crunchy download -o 1.mkv -r best https://beta.crunchyroll.com/series/G5PHNM403/the-dawn-of-the-witch[S01E06] -g 5 -v

At this time, the downloaded mkv file can be played normally.

That's a weird issue, normally this shouldn't happen. Maybe there was a issue while downloading the subtitle file which caused this.

[ltsj]

The problem reappeared when downloading "Case Closed (Detective Conan)"

Remix and remove all subtitles and the problem goes away

Just give feedback on the problems in use

For me, episode 6 video somehow extends to 4 hours length, but only around 24 minutes (the actual length the episode) can be played, after this my video player (vlc / mpv) stops the video entirely. If I remove the German subtitle the video has the normal 24 minutes length. Mysterious.

[bytedream]

In the .ass file which contains the German subtitles, one entry has the end-time of around 4 hours. This is the cause of the extended video length (as you already partially pointed out). Once again a design decision I can not understand ¯\(ツ)/¯.

@ltsj which video player are you using? When I download it on Windows 10 it can be played normally with the built-in video player, at least until the addressed subtitle bug occurs

[ltsj]

I use the latest version of PotPlayer

Fixed in release v2.3.1
