I'm getting a different error when running it on mono:
EPG Collector.log:
http://cl.ly/3r2Q0e3y1t1h0L2u3I2q

CLI output:
http://cl.ly/2U0d0S1N3x2U0b0n251m

@tokyovigilante, I had a look at your last posted log, it looks like the app can't find your files as I see several ""

My config file looks like this:
http://cl.ly/353p1T2O090U060N0m3m
This line is what mono seems to want (windows style)
C:\Documents and Settings\All Users\Application Data\Geekzone\00000000132b514b_.mpg

But on a mac that file is located here:
/Users/technoguy001/.local/share/Geekzone/00000000132b514b_.mpg

Same principle is applied for the xml dir... hope that helps... but if it does you will probably end up with the next error (that I get)

Edit:
Damn, not even <code></code> tags work for code (well.. they do on the editor but it disappears when you post it)

I've realised there is a problem that I need to do some more work on.

In normal running the DirectShow related code buffers the incoming data in an unmanaged memory block. This is done with a C++ DirectShow filter and it allocates the buffer and the .net managed code reads and processes the data from it.

Unfortunately the simulated input code does pretty much the same even though it is all managed code. It allocates the buffer using a .net function that gets the memory from the unmanaged memory of the process which is obviously not going to work when running under Mono.

I need to adjust the simulated input code to use a regular managed buffer when running under Mono. I'll try and sort this out today and let you have another copy as soon as it's done.

Good spotting yeah, lost in the translation to Mono. I now get the same stack trace as you. Hope SJB has some bright ideas...

Speak of the devil! Thanks Steve, we might have this running tonight...

On the plus side the TS exporter/parser plugin for EyeTV is working fine, I've borrowed some PID parsing code from Handbrake to find the DSM-CC PID -

streamtest[10873:a0f] file is MPEG Transport Stream with 188 byte packets offset 0 bytes
streamtest[10873:a0f] next_packet: sync lost @ 8192, regained after 80 bytes
streamtest[10873:a0f] hb_ts_stream_find_pids - found the following PIDS
streamtest[10873:a0f] Video PIDS :
streamtest[10873:a0f] 0x1c4 type H.264 (0x1b)
streamtest[10873:a0f] Audio PIDS :
streamtest[10873:a0f] 0x192 type MPEG4 LATM AAC (0x11)
streamtest[10873:a0f] 0x3eb type ISO 13818-6 DSM-CC U-N msgs (0xb)

Nice work tokyovigilante, can you post the plugin so I can give it a try with my DVB-T stick?

I didn't think this thread would ever evolve into this, very pleased it did though :)

I'm working on getting it up to Github, but there's a couple of rough edges so I might wait for Steve's code. It's kinda useless without ;)

Is it possible for the TS exporter to be generic rather than just for MHEG5?

Ideally you would export every PID that wasn't carring video or audio but that would require you to parse/process the SI packets (not a trivial task) first to find out which PID's they are.

Alternatively I would dump everything.

Incidentally even if you stuck with the specific MHEG5 implementation the Collector needs more than just the MHEG5 PID. It process all the station data and, for satellite, the channel allocation data, which is transmitted on other standard DVB PID's.

Oh yes, the parsing code is just to find the DSM-CC PID for the configuration file. The exporter dumps the whole stream, as per the sample I provided.

The plugin's basic flow is

-Export 65 second raw TS
-Parse file to find DSM-CC PID
-Write EPG Collector config file and spawn EPG Collector process
-Reimport generated XML file to EyeTV.

That's fine.

Can the 65 seconds be parameterized? Some FreeSat and OpenTV collections in Europe are huge (1,000 stations and 100,000 epg entries) so 65 secs won't be enough.

Yeah sure, I can just read it from a settings file, or maybe even make a GUI if i'm super-keen. How long would you need as a realistic maximum?

Bit difficult to say. The Collector has a default timeout of 5 minutes but I don't know if users have overridden that.

How about 10 minutes - the file would be huge though.

I've had a look at the Mono forums and apparently it is OK to allocate and use unmanaged memory. Almost immediately I found some posts that were doing it.

It can't tell from the log/cli posted what exception is being reported. There is no exception in the Collector log and the cli stack trace just indentifies the failing line not what's wrong with it.

Do you have any more info?

Try this one.

I've changed the unmanaged memory allocation to managed anyway.

Same error as before.

The below outputs are from the new build you just posted
Here is the output of: mono --trace EPGCollector.exe /ini="MHEG5 Test.ini"
http://cl.ly/0F0G3i0m3u2t28263K2y

Maybe the --debug switch could be helpful... http://www.mono-project.com/Debugging

edit:
Output using -v switch (verbose)

Seems like im getting an exception (using switch: --trace=N:nothing )

[0xa064c540:] EXCEPTION handling: System.IO.FileNotFoundException: Could not find file "/Users/technoguy001/Downloads/EPG_Collector_for_Mono-1/C:\Documents and Settings\All Users\Application Data\Geekzone\00000000132b514b_.mpg".

Here is the whole CLI output: http://cl.ly/350Y2t1d0S2K3B020T2R

Not to sure how to change this...
