How to implement streaming with subtitle output

hello:
The dvbt channel is streamed to the Android TV. Since the player cannot select subtitles, there are 3 subtitles. Can you output subtitles to the Android tv?

Progtv or kodi for android work perfect.

Progtv is very good, but the interface remote control is not easy to operate, I use the perfect player, but the S905 new products and the HiSilicon chip do not support HW+, so the subtitles cannot be called up.

Or how to use ffmpeg mapping subtitle output

RE: How to implement streaming with subtitle output - Added by saen acro over 5 years ago

Your idea is to burn subtitles in video, or limiting just specific language for subtitles?
First one is type of transcoding. (spawn profile + FFMpeg/Gstreamer )
Second can be done via stream filter menu in TVH.

RE: How to implement streaming with subtitle output - Added by weijian liang over 5 years ago

The subtitle output and the specific language are limited. The stream accepted by dvbt has subtitles, but the subtitle can be selected when outputting to the Android VLC player through the TVH pass channel, and is turned off by default. However, the player I need does not have a subtitle option, and I need to have a subtitle output stream on the tvheadend server.
What is the format of the transcoding type? I have not found the relevant information.
The TVH stream filtering menu filters out certain subtitles. Instead of displaying subtitles?
Can you talk about the specific method of operation?

Thank you！！

ffmpeg -i pipe:0 -filter_complex "[0:v][0:s]overlay[v]" -map "[v]" -vcodec libx264 -preset ultrafast -x264opts keyint=100:min-keyint=50 -threads -0 -f pipe:1

Not 100% shure but with more testing

Can talk about what it means, in fact, I want to learn ffmepg. Is this code on the spawn?
