I am looking for this as well. we use a link encoder that places CEA 608 on line 21. from what I understand, you must capture in 10 bit to see the lines of data in the VANC area. Black Magic has a few lines in the AVOptions that deal with that.
Code:
-raw_format yuv422p10
will capture closed captions as i have tried this in FFMPEG directly. another option also is
Code:
-teletext_lines all
which claims to grab all lines dealing with passing text data. I need this solution now, unfortunately I am not good with python stript.
Hey know its shot in the dark, was hoping maybe someone came up with a solution for this? I am in the same boat, trying to pass through obs but still keep all the data. Thanks!
Hi, looking for any way to get 608/708 out of OBS, preferably out Blackmagic Decklink 4K or maybe NDI. Nothing but crickets when I have asked 3 other threads on the topic.. Thanks in advance!
