how to auto convert HDPVR .ts to mp4 1280x720 in gbpvr?

[tvshowman]

I was hoping to have pvrx2 start the transcoding process.

Code:

<Conversion name="handbreak" exe="HandBrakeCLI.exe" cmd="-i {SOURCE_FILE} -t 1 -c 1 -f mp4 -w 1280 -l 690 -e x264 -b 3000 -r 29.97 -a 1 -E faac -B 160 -R 0 -6 dpl2 -D 1 -x ref=2:bframes=2:me=umh -v -o {DEST_FILE}" targetExtension=".mp4" />

This should work in a bat file in the handbreak folder

Code:

HandBrakeCLI.exe -i temp.ts -t 1 -c 1 -f mp4 -w 1280 -l 690 -e x264 -b 3000 -r 29.97 -a 1 -E faac -B 160 -R 0 -6 dpl2 -D 1 -x ref=2:bframes=2:me=umh -v -o temp.mp4

the problem with .bat files is that pvrx2 will add new movies to encode instead of waiting for the encoding to finish to process the next

Oh heck it works!!

Code:

<Conversion name="handbreak" exe="HandBrakeCLI.exe" cmd="-i {SOURCE_FILE} -t 1 -c 1 -f mp4 -w 1280 -l 690 -e x264 -b 3000 -r 29.97 -a 1 -E faac -B 160 -R 0 -6 dpl2 -D 1 -x ref=2:bframes=2:me=umh -v -o {DEST_FILE}" targetExtension=".mp4" />

Put the handbreak command line file in the "gbpvr/third party/" directory

cygwin1.dll and HandBrakeCLI.exe

add the above code in your config.xml (HINT search <CustomFFmpegConversions> in the config.xml for fast finding)

simply add this line
<Conversion name="handbreak" exe="HandBrakeCLI.exe" cmd="-i {SOURCE_FILE} -t 1 -c 1 -f mp4 -w 1280 -l 690 -e x264 -b 3000 -r 29.97 -a 1 -E faac -B 160 -R 0 -6 dpl2 -D 1 -x ref=2:bframes=2:me=umh -v -o {DEST_FILE}" targetExtension=".mp4"

save and start pvrx2 and it will show up in the video library under transcoding

hehe

Thanks everyone! although I knew about the -i command it appears I failed to put that in my original post and thus it never worked... boink :eek:

update for those following this thread

I am currently recording two shows on the pvr500 and encoding something auto as per my settings from avi files...

I am also recording breaking bad hdtv while transcoding a 250 meg hdtv file I was testing and I had set pvrx2 to suto transcode .ts files to my handbreak script and I was watching an HDTV recording all at the same time no lag or anything (WOW)

and to my surprise the auto .ts file converter kicked in on the finished recording and the pvr never hicupped.

Simply amazing!

i have an older intel dual core duo with 2 gigs of ram and an 8600gt 1gig card.

I figure if I set everything to auto encode then the shows I didn't watch will get encoded to save space and I can watch then later and the ones that I get to watch unencoded I can delete after viewing. The encoding seems to be

"knock on wood" it is like I am not encoding anything in the background.

Just to be clear. If I encode in windows, windows seems sluggish. but when everything is done inside pvrx2 there is no sluggishness and guide menu's etc... are fast as normal.

It is probably encoding around 10fps my guess in pvrx2 with everything at full hilt so that just gives me more time to get a chance to watch it un-encoded first hehe.

I would love to hear it if anyone gives it a go and what their experience is like.

Thanks again everyone for your guidance and help and to sub from some serious coding skills *****

Ohh the movie I compressed earlier on my quad rig

Doomsday(2008)(Nudity)(2.5 stars)_20090927_01300325.ts - 9,014megs

Doomsday(2008)(Nudity)(2.5 stars)_20090927_01300325.mp4 - 2,729 megs

I am wondering if transcoding is a waste of time and cycles. The latest ARCSOFT TotalMedia recorder can record to MP4 format. Is it possible for GBPVR to take advantage of whatever ARCSOFT is doing and also record the shows in MP4 instead of in TP?

Sorry, there is close to zero percent chance I'll support recording directly to .mp4 on the HD-PVR, since it wouldnt be able to watch in-progress recordings, or timeshift tv, leading to support posts.

I should also add that I am using
1280x690 3,000kb's and 29.93fps and only one pass.

I never bothered to wait twice as long for any 2 pass and these parameters seem to work well for me.

You might be better off using a Constant Quality setting than the Constant Bitrate you're currently doing. It will always give the file exactly how much bitrate it needs for the quality you are looking for. CB does a flat 3k, which can be too much for some scenes and not enough for other scenes. It will be somewhat slower than CB, but it's still one pass. Test it out if you haven't already.

Two-pass isn't that great for the same reason -- unless the person is trying to hit an exact file size, the file size will always be too much or too little vs. using CQ, and take twice as long.

What do you change in the command line to get Constant Quality instead of the CB of 3000?

Code:

<Conversion name="handbreak" exe="HandBrakeCLI.exe" cmd="-i {SOURCE_FILE} -t 1 -c 1 -f mp4 -w 1280 -l 690 -e x264 -b 3000 -r 29.97 -a 1 -E faac -B 160 -R 0 -6 dpl2 -D 1 -x ref=2:bframes=2:me=umh -v -o {DEST_FILE}" targetExtension=".mp4" />

I see they just released a major new release of HandBreak. Seems it mentions the constand quality setting and no more need for two-pass encoding.

When you say major update - it certainly looks like it is. An excellent tool gets much better.

I tried a couple of tests last night and this morning and I've always used 2 pass. I used the default settings and the final quality with single pass is superb. It's still not faster for me by much and they state 64 bit OS's should see about a 10% increase in speed. Can't say if that's the case for me.
Still, I'll tweak it a bit more as the final sizes are still a bit larger than I personally prefer.
