Funimation subtitle mux failing again #2987
Description
Plugin Issue
- This is a plugin issue and I have read the contribution guidelines.
Description
I am attempting to view with Japanese audio and English subtitles, using streamlink 1.4.1 on Ubuntu 20.04 with VLC 3.0.9.2.
With --funimation-mux-subtitles and --ffmpeg-audio-transcode aac (the latter required, as per #2615), VLC fails to recognize the format of the embedded subtitles. However, the debug output shows available vtt and srt sub files which, if downloaded separately, work fine in VLC.
Reproduction steps / Explicit stream URLs to test
- Install streamlink 1.4.1 on Ubuntu 20.04.
- Attempt to view an episode using Japanese audio and English subtitles as follows (you will need to supply your own --http-cookie variables):
streamlink --locale en_US -l debug --ffmpeg-audio-transcode aac --ffmpeg-verbose --funimation-mux-subtitles --funimation-language ja --http-cookie "incap_ses_979_998813=#####" --http-cookie "visid_incap_998813=######" "https://www.funimation.com/shows/dragon-ball-super/the-peace-reward-who-will-get-the-100-million-zeni/?qid=ae3f56434b70cdc4" best - The episode plays correctly, but no subtitles are displayed. VLC gives an error, claiming that it does not recognize the codec. Viewing codec information shows that the subtitle track is not recognized.
- Download the .vtt or .srt subtitle tracks listed in the debug outfit, and add them to the running video. Observe that they function correctly, meaning that it's not a symptom of an inability to use these formats in the current version of VLC.
- Run
ffmpeg -i filename.vtt filename.ass(where "filename" is the name of the .vtt sub file you downloaded) and add it to the running video. Observe that it too functions correctly, meaning that it's neither a symptom of ffmpeg's inability to convert webvtt to ssa, nor VLC's inability to play ssa.

Additional comments, screenshots, etc.
It appears that --funimation-mux-subtitles fails on all Funimation content I've found unless --ffmpeg-audio-transcode aac is added, as advised in #2615. Users may find this requirement unintuitive, particularly as the equivalent Crunchyroll module does not require either such parameter, but rather "just works".
