Teletext subtitle track leads to strange clustering and interleavement
Hello,
I have uploaded "Teletext.Subtitles.ts" to your server. This file consists of the end of a TV movie and the beginning of the next one. Both contain teletext subtitles, but at the beginning of the second movie, there are no teletext subtitles for the company logos, so that there is a gap in the subtitles. It seems that this affects the clustering: At the beginning of the gap, there is a video keyframe that doesn't start a new cluster and the last subtitle packet before the gap is muxed too late (despite having a timestamp of 49.402s, it is muxed besides packets with timestamps 55.162s and 55.182s). I don't know if there is something wrong with the interleavement of the original file. Maybe this has to do with the fact that the duration of a teletext subtitle packet is determined by a second, empty packet?
