SubtitleRender - SRT subtitles in SageClient w/ HWA

[babgvant]

SubtitleRender is a DirectShow filter that pushes SRT based subtitles into SageTV. The main benefit versus a filter like VobSub is that this approach does not break hardware acceleration (important for HD h.264/VC-1).

The filter supports switching between up to two subtitle streams (CC1/CC2) if the filter it is connected to implements IAMStreamSelect (i.e. Haali Splitter).

Installation Instructions:

1. Install SageTV 6.5.18+
2. regsvr32 the attached filter
3. Default STV - Mike was nice enough to make a STVi
4. SageMC - install SageMC_6_3_9a_46+
5. If you installed version 1.0.0.1 you must run regsvr32 in the new ax


Thanks to Jeff for providing the necessary documentation and for changing Sage to look for a Line 21 decoder where there shouldn't be one.

1.0.0.2 - 07/01/09
- Change merit to MERIT_PREFERRED+2 to beat out the Internal Script Command Renderer
- Add support for MEDIATYPE_TEXT to connect to Haali when no subtitle is set as default
- Register supported media types when filter is regsvr32
- Select first SRT stream on connect to support when no subtitle is set as default
- Fix deadlock issue when media type changes
- Clear subtitles when OFF is selected
- Fix clearing subtitles when seeking

Known Issues:
- When subtitles are initially turned on, it can take a few seconds for them to show up. I think this is due to samples queueing at the renderer (i.e. the graph is actually a few seconds ahead of what you see).

Would this enable a Sage Client to display subtitles from a .TS file generated through Clown_BD off of a BD disk?

It only works with SRT subtitles currently, but I will probably add other text based formats if there is demand.

I've only tested the solution with SRT subs embedded in a MKV, but I would expect it to work with external srt files if a source filter (MPC HC has one) is installed and Sage supports loading the file (I don't know if it does on the PC).

Sounds great...

But for now this will always show the subtitles if present? No way to turn them on/off/toggle between them within the SageTV UI?

That's what step 3 or 4 is meant to address - w/ the added benefit that 2 discrete sub streams can be toggled.

Hi Andy,

I'll generate the stvi for you durning my lunch hour later today and post it in this thread.

Aloha,

You don't need the filter if the SRT subs are external. The latest Beta/RC of SageTV handles those for all types of clients already.

Thanks! Every time I tried to export my change I ended up w/ too much (broke the STV) or too little (didn't do anything).

Your implementation is better (and not just notepad thing) because it will work for files that aren't MKV.

Very slick! <strike>Does it implement IAMStreamSelect to switch streams?</strike> nm, if it already works there's no point to loading this filter

Hi Andy,

Here's the import for the default STV.

Aloha,

This doesn't work for extenders, correct?

You don't need it on the HD200 (not sure about the other ones). It already supports SRT embedded in MKV.

I must be doing something wrong because some of my MKV's do not display the option for CC, even though they are embedded.

I have to double check.

Has anyone actually gotten this to work? I muxed in an .srt file on the movie Defiance (just an example), which is an .mkv file. The subtitles show on Media Player Classic. I have the menu options when watching on the HD200 on extender mode, but even when turned on they don't show in Sage. I am not using the plugin that is referenced, it looks as though it should just work in the latest beta.

Any ideas?

Depending on how you create the mkv this version may not work (I mux the SRT as a default track which changes how Haali presents them).

I'm working on a new rev that takes a more flexible approach, should be ready w/in the next couple days.

AFAIK this filter is the only way to get embedded SRT working, if the files are external they should work w/o doing anything.

[teddykgb]

Thank you for the prompt response! I (stupidly) wasn't aware that they even worked without embedding them.

Which brings up a follow up question, how on earth do you ever find a srt that is synced to the audio?

[babgvant]

Haven't noticed a problem with that when ripping (w/ eac3to) or converting from ATSC.

I didn't know external files worked on the PC until Jeff mentioned it a few posts back.

[teddykgb]

I'm sorry, I probably didn't ask that very intelligently. I ripped Defiance from a blu-ray and then was trying to add back an srt (off of subscene) after the fact.

Can I assume the easier way would be to rip the srt from the blu-ray? I've never done that.

[babgvant]

I use eac3to to extract the sup from the BD, then suprip to OCR into SRT.
