Commercial Advance Beta Release

[JasonJoel]

Hmm.. Well... Mine in my properties file says VBR=1. I assume that means it is VBR... (?)

Are there any CBR base recording profiles that will still have closed captions in them for use in COMSKIP??

Thanks in advance!

I see the source of my confusion now; they seem to have changed all the DVD settings from CBR to VBR in SageTV 2.1.


SageTV 2.0:
seeker/recording_qualities/DVD\ Extra\ Long\ Play\ ~\ 1.8GB\ per\ hr=DVD Extra Long Play,384,48000,4125000
seeker/recording_qualities/DVD\ Long\ Play\ ~\ 2.5GB\ per\ hr=DVD Long Play,384,48000,5750000
seeker/recording_qualities/DVD\ Standard\ Play\ ~\ 3.25GB\ per\ hr=DVD Standard Play,384,48000,7250000

SageTV 2.1:
mmc/python2_encoding/DVD\ Extra\ Long\ Play=videobitrate\=3000000|peakvideobitrate\=4400000|vbr\=1|width\=720|height\=480|audiobitrate\=384|outputstreamtype\=10|audiosampling\=48000
mmc/python2_encoding/DVD\ Long\ Play=videobitrate\=4800000|peakvideobitrate\=6000000|vbr\=1|width\=720|height\=480|audiobitrate\=384|outputstreamtype\=10|audiosampling\=48000
mmc/python2_encoding/DVD\ Standard\ Play=videobitrate\=6400000|peakvideobitrate\=8000000|vbr\=1|width\=720|height\=480|audiobitrate\=384|outputstreamtype\=10|audiosampling\=48000

Looking at the settings I think this custom setting should work for sagetv 2.1.
mmc/python2_encoding/DVD\ CBR=videobitrate\=3800000|vbr\=0|width\=720|height\=480|audiobitrate\=384|outputstreamtype\=10|audiosampling\=48000

In 2.0, the base mmc/python2_encoding settings were not visible, so they could have been VBR w/o us being able to see it. The Best, Fair, Good, & Great rates also have outputstreamtype=10, same as DVD lines -- they are CBR, so maybe they will do CC w/o having to creating a custom DVD rate? (I haven't tried this.)

Maybe Frey changed the default values for those settings at some point in the beta so more settings allowed CC? I just looked at one of my old install dirs & its properties file had it set to 0. All of my current installations have it set to 10. These comparisons were based on basic configuration properties where I deleted the old ones so that a new prop file was created with the default settings. But, even my normal-usage properties files with all my customizations now have outputstreamtype=10 for the rates I mentioned.

Back in v2.0 the DVD qualities were VBR (as reported by Ulead DVD MF info).

I do believe Frey did alter the other settings in v2.1 to be DVD compliant, and yes the the ones you listed do work for CC (which is why I assume the streamtype was actually changed for them in v2.1, but could also have been to make burning DVD's easier without a need to re-encode).

[JasonJoel]

Thanks for the info everyone!

all streams are somewhat VBR, but I believe the DVD qualities are really setup to be CBR

you can use a CBR format such as MAX quality and then use the nvidia decoders and you will see it is not constant

but then of course Frey could have made them VBR but one way to check is to do the math

Another way to check is to look at the properties file and see that the DVD rates are set as malore posted them above, with vbr=1 & videobitrate and peakvideobitrate set to differnet values.

Jere,

Wanted to let you know that the new comskip .61 is now crashing on me when run from a remote sageTV client. The last version was fine. I'll enable logging and send you the log.

[Jere_Jones]

Just out of curiosity, would there be any interest in running comskip on shows as they are recording? I figure this would have 3 major advantages:

1. Fewer resources required since comskip could only process at 25/30 fps.
2. Commercials could be flaged before the show is even finished (kind of a "flag as you go" concept)
3. A full detection would be complete about 4-5 seconds after the show is finished, instead of 7-20 minutes.

Any input/opinions/ideas?

Absolutely If it can be done.

[White94Cobra]

That would be perfect!

Definately sounds like a good idea - I'm just wondering about the file sharing/permissions aspect of it... but you're the guy writing the code, so what am I worried for

OMG ... you would be my hero!

[ToxMox]

Ditto! Would be pretty groovy. Although what would happen if lets say 4 shows were recording at once? I'd be concerned about the cpu load at that point.

[ajuhawk]

I thought of another request - this is more for the STV makers though - it'd be really nice to have a little icon or screen or something that let's you know that comskip is running. It would be even cooler if it could tell you which file it was processing. I'm not sure how easy and/of if this is even possible. But I thought that maybe since Sage calls comskip and tells it which file to run.... anyway, just a thought.

As always, thanks for all the hard work by everyone out there, I am really enjoying the end product!

Next you'll have it working on LIVE TV!!!

[Jere_Jones]

Ok, I've got comskip scanning a file as it's being recorded. I've had it running on three shows as I was recording them with 15% cpu (after the logo had been identified). I also watched one of the shows as it was being recorded and comskip scanned (in addition to the other two shows being recorded at this time. As far as I could tell there was NO disk thrashing going on. Maybe comskip was getting it's info from a cache or something since it had just been written to the disk. :shrug:

Anyway, I'd like some ideas from the StudioHaves on how to notify sage that it needs to reload the .txt file. Right now, comskip acts as normal, just that the file is processed as it is recorded. Eventually, I plan on comskip writing identified commercials to disk as soon as it can. But to be useful, sage would have to reload the txt file and I don't think there is any reason to reload it every second. Maybe use one of the custom commands to reload the file. Then if comskip wrote a new commercial break to the file, then comskip would send an event to sage to say "HEY, there's new information!!! Come and get it!!!!" or something similar. At this point comskip really WOULD work on LiveTV.

I'll release it as soon as I get Deadbolt's log so I can figure out why it's crashing on him.
Jere

[sleonard]

Udaman, Jere. I can't wait to try it out.

[JasonJoel]

YES. That would be very handy!

Is lame to tell it to COMSKIP (because there is no CA indication), and then have it say '0 files processed in 0 seconds' (or whatever) because it is already processing...

They could get this info from the BAT file that COMSKIP makes when it is procesing a file.

Add that your to-do list Cayars ( ).
