With Nimble Transcoder, I can forward subtitles to output stream, but I want to add subtitles directly to the video. Could you help me to do it. Thank you
Nimble itself has no feature to add/produce subtitles for a live stream on the go.
For VOD, you can place subtitles next to the media file. More details:
Thank you very much
Hi, I have the same question. I am using overlay function in ffmpeg for insert subtitles directly into video. You have overlay implemented. Are you thinking about this addon?
Could you clarify your use case? Do you mean adding subtitles to Live stream or VOD? What subtitles format are you referring to?
Transcoder doesn't support VOD and as Alexander already mentioned a method for adding subtitles for VOD.
As for Live Streams, CEA-708 or DVB subtitles passthrough supported as described on the following documentation pages:
Inserting subtitles from the file to Live stream is not supported at the moment.
Hi, I have multicast input and multicast output. DVB-subs passthru is working correctly. I tested it. But I use this streams for my IPTV HLS, DASH streamers, where I cannot use dvbsubs. Therefore I am using overlay and insert subtitles directly to video. It has pros and minus, but it has more pro for me.
I know, that you do not support it now. I am asking, if you will add this function in future?
ffmpeg -i udp://126.96.36.199:1234 -filter_complex "[0:v][0:s:1]overlay=main_w/2-overlay_w/2:main_h/2-overlay_h/2" -map 0:v -map 0:a:0 .....
Thank you for the explanation, Ladislav.
We do not have plans for this feature in the near future, unfortunately.
