Hi Anshul,

Could you explain what your patch does? I've read the patch but I don't
fully understand what changed conceptually.You moved the a bunch of code in
the decoder from dvbsub_display_end_segment to dvbsub_parse_page_segment.
What does this mean for the decoded subtitle? Will the timings still be

My understanding - as I explained before - is that the problem with the
transcoding is rooted in the operation of the dvbsub *en*coder. How does
this change fix the problem? (To be clear, I'm not saying it DOESN'T fix
the problem, I just don't understand if and how it might fix it.)

Did anyone compare the timings on the subtitles?

King regards,
