New DVB subtitle filter (TsReader based) - Page 6

risu · 2007-08-06, 08:41

I can't get subs to show with any of those three new filters. The one based on previous ts-filter worked. Tourettes, does the new filter show subs on the clip I provided? VLC sees the subs on that clip. Is there some bad data on my transport stream? I'm using DVB-C card if it matters.

The .ts you uploaded is a bit oversized, 1,5 GB is way too large. A sample of less than 50 MB should be more than enough to determine if there is a problem with your .ts

Usually the "problem" is that the dvbsub filter currently only supports DVB subtitles, not teletext subtitles.

Thanks but I know all this. As I told, previous filter worked for me. We don't even have teletext subs here. And testing the recorded clip with VLC shows DVB-subs where MP dvbsub-filter doesn't. So there has to be something about the way transport stream is sent here that confuses tourettes subtitle-filter.

Hi Risu

Have you tried the latest dvbsub-filter? I have tried to watch your test-stream at it's showing nicely here.

Have you unregistred the tsreader.ax before registred the new tsreader.ax?
Have you registred the dvbfilter correctly?
Have you made the text-file usetsreader.txt in c:?

One additional thing risu could try, is to check that dvbsub2.ax is loaded and connected by checking in Graphedit.

Thanks Seidelin, just checked. Subfilter is loaded and mpeg2 demux subtitle is connected to its input but there's no output from dvbsub2 on graph. I guess it should go into subpicture input on nvidia video decoder? Any tips how to fix this?

It's correct behaviour that the subtitle filter doesn't show output pin (as it doesn't have one). Subtitle filter has an internal interface that MP uses to transfer the subtitles. The subtitles itself are rendered on the MP side in directx for following reasons:

1) mpeg2 decoder subtitle pin is only using 4 colors (as per DVD standard)
2) MP uses VMR9 in YUV mode and in that it's no possible to use bitmap overlay.

Could you make a screen shot of that GraphEdit view? Just to make sure that it's ok as "mpeg2 demux" sounds like it would be using the TSFileSource.ax + MS demuxer.

btw. That sample file plays also nicely here with the subtitles.

Seidelin, is the version 3 still hanging when zapping?

Ok, my bad

I had tsreader working before but after that I reinstalled the whole system and didn't double check it worked after I made new useTsReader.txt to C:\ .. it was just that it got named useTsReader.txt.txt . Now subs are showing! Thank you!

No problem, good to know that the subtitles seem to work now.
