I am trying to decode mpeg TS over UDP with subtitle stream into SDI port. Command:
ffmpeg -i "udp://224.1.1.1:2000?localaddr=192.168.100.109&overrun_nonfatal=1&buffer_size=13107200&fifo_size=1000000" -map 0:i:0x7d1 -map 0:i:0xbb9 -map 0:i:0x1389 -teletext_lines all -c:v v210 -f decklink 88:02a07762:00000000 if I don’t use the map command, the video and audio are working fine but the subtitle stream is ignored, if I specify the subtitles stream (PID 0x1389 in this example), I get the following error: Input #0, mpegts, from 'udp://224.1.1.1:2000?localaddr=192.168.100.109&overrun_nonfatal=1&buffer_size=13107200&fifo_size=1000000': Duration: N/A, start: 43965.121844, bitrate: N/A Program 1 Stream #0:0[0x7d1]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p(tv, bt470bg, top first), 720x576 [SAR 16:11 DAR 20:11], 25 fps, 50 tbr, 90k tbn Stream #0:1[0xbb9](eng): Audio: mp2 ([4][0][0][0] / 0x0004), 48000 Hz, stereo, s16p, 384 kb/s (clean effects) Stream #0:2[0xfa1](eng): Audio: mp2 ([4][0][0][0] / 0x0004), 48000 Hz, stereo, s16p, 384 kb/s (clean effects) Stream #0:3[0x1389](spa,spa,spa,spa,spa,spa,spa): Subtitle: dvb_teletext (libzvbi_teletextdec) ([6][0][0][0] / 0x0006), 492x250 [sost#0:2 @ 0x55b721f91b40] Automatic encoder selection failed Default encoder for format decklink (codec eia_608) is probably disabled.
