ffmpeg SRT to DVB_Teletext

Postby dragmore88 » Wed Apr 05, 2017 8:16 pm

hi. Does anyone know if the dvb_teletext module supports encoding to dvb_teletext ? Im running 3.2.4.

When running this syntax:
Code: Select all
ffmpeg -i video.mpg -sub_charenc ISO-8859-1 -i video_nor.srt -codec:v libx264 -profile:v high -preset fast -b:v 2000k -maxrate 2500k -bufsize 5000k -codec:a aac_at -b:a 128k -scodec dvb_teletext -metadata:s:s:0 language=nor output_file.ts


Im getting this output:
