Streamed WebM S_TEXT/UTF8 track not visible in VLC
Posted: 29 Oct 2018 19:46
Hi team,
Trying to get a webm track in S_TEXT/UTF8 format working in VLC. Strangely, it works when the file is on disk but when streamed, I run into issues. I'm still pouring though libav/vlc code so haven't figured this out on my own yet. Any help/pointers would be greatly appreciated.
