You can import that functionality with an STVi that Nielm created:

Jere,
Time for a progress report. Hows progress on the HDTV detecting going? You know, you aren't allowed to take any vacation or anything. My commercial detection is just too important for you to be gone.

I'm planning some time off in October, so you'll have to wait till then. So, back at it!!!

[DFA]

Jere, et al:

Does current version of SA work with nielm's recently released WebServer v.2.7? It did not fully work with 2.6.

Or do we still need wait for an SA update?

Humanzee,

I have SA decoding TS files correctly if, and only if, I tell it before hand what PID's to demux. I'm having a heck of a time parsing the program maps so that SA can figure those ids out for itself.

DFA,

Not yet. It is very high on the todo list though.

Ok, not sure what that means but it sounds like you are making some progress. So that is good.

On another note, there was discussion in the past about a new output file to include aspect ratio info. I was thinking today when writing in another thread that aspect ratio could be just the start of it.

You could make some sort of recording statistics output file to include various information that could be used by stvi developers etc.

Such as
Broadcast resoultion, 480i-1080p
Broadcast Aspect Ratio
Program Aspect Ratio
Recording length
Recording size in bytes/Mb/Gb
Video Codec
Audio Codec
Bit Rate
????

Of course there is probably other info that could be useful for you too for debuging outside of a log file. maybe how long it took to detect, etc.

This opens the door for creating more adaptive settings like automatic aspect ratio switching, automatic decoder/renderer selection, more accurate free space statistics based on bit rates observed for HD recordings vs SD etc. etc. etc.

Probably usefull outside of SageTV too, I know you develop for other pvr platforms too. What do you think?

Thanks for the help Chris! I did get the commerical skipping to work, and I also did not process commerical free channels with the web server version 2.6. It worked great on my Windows 2000 Workstation. However...

Since that time, I rebuilt my computer with Windows XP Professional so that I can defrag the 64K large block size.

I installed SageTV 4.1, Show Analyzer 0.6.2.214, DirMon 0.2.3, and Nielm's STVi import. SA & DirMon are working to process commericals. My next step was to install the web server again to avoid processing non-commerical channels.

Now, Show Analyzer cannot log into the web server (when testing the connection in Show Analyzer). I disabled the firewall and I am able to log into the web server with both IE & Firefox. There is a checkbox for the web server version 1.6 and earilier versions.

Is it possible that Show Analyzer is not compatiable with the version 2.7 web browser? Or, could there be some other problem?

Attached is a screenshot of the error message.

Not that this may be of any help or not but it seems that the nVidia "TS Info Parser" DS filter is very good at this. Many of us have this filter. Maybe it can be employed or provide some clues although w/o source code, difficult to extract much "how to". But if it can be used in the interim, many of us could be off and running with that.

Note that for the original STB Firewire capture project, a Graph was created using various filters that demuxed and remuxed the MPEG-TS to MPEG-PS in real time. Only one combination of filters was I able to find and string together that did this successfully; the nVidia "TS Infor Parser" being one of them.

davepan,

I will be including support for nielm's websever version 2.7 in the next release of SA.

DFA,

All of SA's demuxing and decoding is custom coded. No use of DShow at all. Thanks for the the info though.

Jere

[DFA]

If I recall correctly from my reading of posts, I think Nielm had a bug in 2.7 that should result in a 2.8 bug fix release shortly.

It might be easier to make use of the LCD Smartie plugin that neilm created. It listens on a tcp port and spits out all of the current status data.

[geogecko]

Jere.

I have SA setup to only be able to use up to 25% CPU utilization. Yet, when I was having problems watching an show, I saw up to 90% sometimes.

If I let DM launch up to 3 instances of SA, does each instance get allowed 25% CPU utilization? So that would be a total 75% if I had 3 instances of SA going at once?

If so, I need to limit it to more like 10%.

Also, for some reason, I'm seeing SA ignore the rule to ignore commercials 180 seconds from the end of a recording...but I'll have to verify that one.

I think you need to set SA at a lower percentage. SA's configureation is for each instance, I don't think that SA knows if there are more than one instance of itself runnning. Therefore each instance would attempt to use 25% of the cpu. However, I have noticed that if you are detecting a live program it doesn't use all that it is allowed. Because the detection process is slowed down to 1x it doesn't need all the cpu cycles.

Of course when you have multiple tuners you can still end up with lots of cpu being used by SA if you are detecting and recording several shows at the same time. Some of my shows are also HD, which for now can confuse SA at 1x and sometimes makes it hang up. Because of this I changed Dirmon to only decode after the a file is finished being writen too. I set it to use no more that 30% and to do only one show at a time. I rarely need to watch anything within a couple hours of when it recorded so by the next day everything has been detected.

When Jere figures out the HD detecting stuff, Ill probably let it run real time again. We will have to wait and see if HD detecting takes more cpu than SD.

[geogecko]

Makes since, and that's what I was starting to think.

I am starting to think along your lines, and only let it process one show at a time. I was recording three shows tonight (two SD, and one HD), and SageTV tanked 3 times. It appears that SA was using way more resources that I wanted it to. I think I'll just restore SA to use 100 resources, instead of the current 33...at least for now.

I'm getting there.

HD will always take more cpu then SD. Decoding it will, if nothing else.

Jere

[DFA]

If not more CPU than at least a proportional increase in time. Bits are bits.

Hey Jere, any chance of an interim update release of SA that works with latest rev. of nielm's Web Server?

We all look forward to HD-TS commercial detection feature for SA.

I'll try to get one out this weekend.

Cool, ShowAnalyzer currently can process around 25% of my HD recordings, I'm looking forward to having the commercials marked on all my shows again.

[ripple]

Doesn't the new 5.0.2 release of Sage generate .mpg files now instead of .ts files for HD?

How does this affect SA?

Thanks,
Kevin

[lovingHDTV]

Sage has been generated PS streams for sometime now. I have had no luck using SA on the streams but comskip works fine.

I'm hoping SA will work soon so I can get the capability to link to the webserver, I really miss that with comskip.

[hchucky]

curious...what are the benefits of linking to the web server with SA?
