Help needed with DVB subtitles (2 Viewers)

[Nyll]

Like Risu I had to regsvr32 DVBSub_release.ax

On national danish television (DR1) the subtitles are delayed about 1-2 seconds. The subtitles are showing nicely though. Good job so far. Thanks a lot guys!

I think one reason for timing problem is pes decoder.
Looking at the PayloadUnitStart to decide when a pes packet is ready
will make the subtitles to be delayed (when the next subtitle begin the previous
is delivered).

You should look at the actual pes size and when that length is received the
pes is ready.

Excellent work.

Working with the UK DVB-T stream and those MUX's that have subs with TV3.0 (not all work as of yet!)

Delay seen as posted above.

One problem I had was geting the regsvr32 DVBSub_release.ax to action (my error) I had to copy to sytem32 folder for this to action, I have forgottten how to do this from other folders.

Ok, I am seeing memory leaks while rinning MP with subs, this could be normal but the memory footprint is almost doubling to nearly 30000k in a few minutes.

Also the subs are spot on time wise when not running 'live'.

When 'live' there is a delay and sometimes the subs dissapear completely.

Running 5 seconds behind live gives an almost faultless presentation of subs to dialog and infact going back to 'live' from this and the subs stay in time without delay.

Accessing a second audio stream causes MP to lock needing task manager to end it.

Fantastic. Seems to work here in Finland. I haven't investigated whether it leaks memory or not, but the subs seem to be perfect. Please help this man to finalize this fantastic job!

Would be nice if eventually subs would show when tv-screen is shrinked (EPG, tv-menu). Also there seems to be green outmost color at least on finnish dvbsubs I can't see in VLC or other programs (white center, black border and then there's narrow green).

Currently Subs are rendered only in the full screen (as you noticed). This shouldn't be a big change to get it working in other places as well, but I consider this a minor issue only and won't be looking into it before I or someone else is able to fix the subtitle timing issues.

I noticed also that green color around the subtitles, it's propably caused by bug in alpha channel calculations. Also this is so minor that I won't be looking into this before the bigger issues are solved first.

I guess it shouldn't cause the timing issues I'm seeing (subtitles have been shown before the actual presentation time). Also subtitles are send ahead in the time in transport stream (In Finish test data I receive the subtitles sometimes 5 seconds earlier than the real presentation time).

As you clearly seem to understand C++ & DVB could you have a look and try to debug the timing? I'm really short on time and I don't know when I have some free time that I can devote to coding (in a month, maybe before mid summer.. who knows).

Hmm.. I haven't seen any memory leaks lately. Could you upload some samples of .ts files that are causing some memory leaks? Otherwise there isn't anything I can do to track those down.

Same goes with the second audio hang.

Requirements?

Hi is this only running on the TV Server in single seat, or should it be working in myT also?

I have regged the release.ax but no subs are being displayed

 

[tourettes]

Works (and will work) only with the new tv engine 3. Currently only in single seat, but supporting multi seat configurations is almost done.
