Specify PIDs in Vprj file?

[jmonier]

Would it be possible to specify the primary video and audio PIDs in the Vprj file? Curently they are not there and this results in VideoReDo picking the wrong audio stream. For SageTV the PIDs seem to be standard so inserting:

<InputPIDList><VideoStreamPID>224</VideoStreamPID>
<AudioStreamPID>129</AudioStreamPID>

seems to do the trick.

Currently I'm having to insert this manually in order to get the correct output from VideoReDo.

Is there a closing tag for InputPIDList? Something like </InputPIDList>?

That's a good point, come to think of it, but that's the way it was given to me and it seems to work fine.

Can you post a working file with that in it?

Are these for TS files?

Ok, here is a vprj file that was generated by Showanalyzer from a SageTV .mpg file. I have manually added the stream tags and confirmed that it does what I want in VideoReDo. (Note that I added the closing tag for InputPIDList. I did see it included in another vprj file although it seems to work equally well with or without it.)

The PIDs in the original Transport Stream have completely different numbers but in this case I'm strictly interested in the SageTV .mpg file.

And SA finds that audio stream? Interesting because the PID 129 is the same as 0x81 and that is, as per SA, not good. Audio streams in program stream containers can only have a PID from 0xC0 up to but not including 0xE0. 0xBD is also accepted as an audio stream. Everything else should be rejected.

Anyway, the modifications are done and will be in tomorrows release.

Thanks for the quick response. It's much more than I expected.

I'm not sure if SA actually finds that audio stream or not. It may just be in the .mpg file for VideoReDo to find. I presume you're questioning whether SA is finding and using that audio stream for commercial detection. That I can't really say.

The .mpg file (with the 0x81 stream) is what I get from SageTV although it may be that it is really defined by the HDHomeRun tuner. I haven't looked into that. In any case, for SA to use the audio streams it will have to recognize the 0x81 stream because that's what is used even if it's not legal.

A side note of interest (but probably of no use) is that the 0x82 stream from the local CBS broadcast contains audio for ONLY the commercials. It is mute for the program content.

0x81 would be legal for a Transport Stream, but not a Program Stream. As I understand it, the HDHR produces Transport Streams, so that should be just fine.

I would think that a file with a .mpg extension (which is what we have here) would be a Program Stream. Normally a Transport Stream file would be .ts or .tp. I haven't looked into the file to see if it has Transport Stream packets. Do you ignore the extension and look to see what the actual stream is to decide whether 0x81 is legal?

I always ignore the extension. I have to determine the type of file before I can find the PID's.
