No, they are detected *while* demuxing the input: > [mpeg @ 0x6d89bc0] New subtitle stream 0:7 at pos:26603534 and DTS:31.16s > [mpeg @ 0x6d89bc0] New subtitle stream 0:8 at pos:26607630 and DTS:31.16s > [mpeg @ 0x6d89bc0] New subtitle stream 0:9 at pos:26611726 and DTS:31.16s > [mpeg @ 0x6d89bc0] New subtitle stream 0:10 at pos:26615822 and DTS:31.16s > [mpeg @ 0x6d89bc0] New subtitle stream 0:11 at pos:26619918 and DTS:31.16s > [mpeg @ 0x6d89bc0] New subtitle stream 0:12 at pos:26624014 and DTS:31.16s > [mpeg @ 0x6d89bc0] New subtitle stream 0:13 at pos:26669070 and DTS:31.16s > [mpeg @ 0x6d89bc0] New subtitle stream 0:14 at pos:26673166 and DTS:31.16s > [mpeg @ 0x6d89bc0] New subtitle stream 0:15 at pos:26677262 and DTS:31.16s > [mpeg @ 0x6d89bc0] New subtitle stream 0:16 at pos:26685454 and DTS:31.16s > [mpeg @ 0x6d89bc0] New subtitle stream 0:17 at pos:26695694 and DTS:31.16s > [mpeg @ 0x6d89bc0] New subtitle stream 0:18 at pos:26746894 and DTS:31.2s ffmpeg needs to detect them *before* demuxing. That's why I told you to use large values for "-probesize" and "-analyzeduration". They tell ffmpeg to look deeply into the video before deciding which input streams are available. Then "-map 0" would pick them up for the output, or you could select them with "-map 0:s:N". (Possibly, you can derive useful values for "-probesize" and "-analyzeduration" from "pos:26746894" and "DTS:31.2s", but I'm not sure. For unknown input VOBs, you may need to specify the maximum possible values, which would be 9223372036854775807.)
