Sure it was too big for the forum so I will send it to you.

I think I found the cause. See if this fixes it.

[mvallevand]

Yes that fixes the crash in NRecord, but unfortunately not using NPVR's built in recording service which does slow testing a bit. Now I have a few more questions

1 Is StartStream supposed to return a handle of some sort or zero?
2. Cancel works against the database but the plugin doesn't get any indication to stop. Do I have to poll the status field in the datbase?
3. Does the file have to be a transport stream?

Are you saying you want to be able to use the local recording service inside NextPVR.exe instead of having to run nrecord.exe? You should able to do with this minor tweaks to the config.xml.

1 Is StartStream supposed to return a handle of some sort or zero?

It should be non-zero. I usually use some incrementing handle number. ie, 1 then 2 then 3 etc.

2. Cancel works against the database but the plugin doesn't get any indication to stop. Do I have to poll the status field in the datbase?

It will call StopStream on your recorder plugin when it stops any recording or live tv session.

3. Does the file have to be a transport stream?

Yes. You might be able to get away with non transport stream for recording, but you wont be able to for live tv or playing in-progress recordings.

I can turn in on the internal recording process but it still stops at the same spot before StartStream is called.

Yes I am see that now. Can I use Console.WriteLine() with NRecord RUN ?

Thanks, I was hoping to us GBRecord to test I will have to think of another way. This will probably be an issue when I look at the Graph Recoder plugin.

There is no reason this shouldnt work. If you reproduce and post the npvr.log, I'll take a look.

Yes, you should be able to.

In most graphs you can probably take the separate MPEG2/H.264 video stream, and AC3/MPEG1 audio stream, and connect them to the ""MainConcept (HCW) MPEG Multiplexer-Plus" filter, then connect the output to the 'NPVR Writer' filter.

Attached, the trace seems the same

I was thinking of the graphs that create avi or wmv files with specialized hardware.

Yeah you pretty much have to stick to transport stream files. Otherwise you get all sorts of complications with how to do live tv and how to play in-progress recordings etc. Pretty much everything produces content that can be put in TS files, so its not a big problem.

Ah, I see what is happening. Unfortunately you might need to stick to testing it with nrecord.exe for now. It looks like I'll break some plugins if I fix this. I'll have to note it down and change the interface slightly for the next release.

[mvallevand]

No worries, I am used to debugging with NRecord RUN. Everything is working fine testing with GBRecord even for in progress and I am quite pleased.

- For LiveTV I assume I just create one big file. I assume you are responsible for deleting it?
- I don't see any duration passed, should I just keep recording until you stop? This seems risky.
