Who would like to see DVD/VCD burning capability?

[jorm]

I would probably do the free route. Just so it is a universal solution.

I do have a suggestion though.

Can we create a batch file that burns the dvd that the plugin invokes instead of the plugin shelling each call see below.

%1 mpg
%2 DVDDIR
newfile we should delete as the last step.

mpgtx.exe -d %1.mpg
mplex -f 8 -o newfile.mpg chunk-0.m2v chunk-0.mp2
dvdauthor -o [%2] -f newfile.mpg
dvdauthor -o [%2] -T
mkisofs -o imagename.iso [%2]
del newfile.mpg
del chunk-0.m2v
del chunk-0.mp2


The logic is as follows. If you have a divx show that they want to transcode back they can put that step in.

If they want to use videoredos command line interface that takes the comskip.txt file and removes the commercials then saves the mpeg back they can do that before starting the burn.

ran into a brick wall, mpgtx.exe doesnt like VBR (well i think its because of the VBR, old recordings work fine, new ones dont). so i need another command line app that does the same thing as mpgtx.exe once that is done, ill consider the bat, the problem with converting from divx is it will take time, taking time is annoying. and also im sure you'd run into sync problems,its always the case, but in the mean time, crappy vbr, sure it makes the files around 40% smaller, but my life is tougher now , and the beat goes on.

sub when gbpvr records an mpeg2 file does it add the header to the file? cause the only error i get if i remove the demux part and try to use a gbpvr mpeg file is "system header not found" "make sure your system header is 18 bytes!!!", and if that is the case, could you change this, or anyone know of a command line tool to add the header?

Reven, you might want to visit doom9.org and check out ProjectX. I had some problems with aspect ratios that ProjectX was able to correct (my recording card writes the aspect ratio out as 1:1 instead of 4:3). Don't know if there is a command line for it, but all source is included (written in java).

No, I dont do anything to the file. The file only contains the MPEG2 stream produced by the PVR card.

With respect to

Quote[/b] ]now vote time, nero or mkisofs (free one)

my preference would be mkisofs. I have not used Nero to DVD's as for a long time it did not produce a 100% compliant dvd structure. It probably does now, but the mkisofs is a more robust method.

BTW, a nice GUI interface for this can be found at ImgTool plus Jörg Schilling has written the famous CD-R tools so you know mkisofs is going to be good at its job.

As for an alternative to mpgtx.exe for command line demuxing, one possible option might be ffmpeg. This apparently can pull out the video and audio from an mpg stream.

You may also want to check out rejig - I use this all the time for demuxing (need to check if its command line supports this) though the src code is available which might be of interest if you wanted to make this available via the command line,

Cheers,
Colin.

hey guys been busying with other stuff in my vids, anyway laid the ground work for dvd burning.
so on top of to do list is dvd burning. so ill try out the suggested demuxers, not sure about the java route, i hate java, sure i was first taught on java, its a real easy language, so similar to C# but i hate java, it can be a real pain, i hate having to install the JVM or JDK (or whatever they are calling it now) i want the minimum amout of crap on my htpc, and the .jar files i always run into trouble with those, another program usually tries to open it (yeah my fault i didnt uncheck the damn box in winrar, but its annoying).

ive heard of rejig ill look into that, but if anyone else finds a way to take the recorded mpeg2 files from gbpvr and process them with dvdauthor (vbr files) either demuxing them then combining them again, or just fixing a header or whatever via the command line, let me know. everybody should be looking for this, thats an order, come on we all would love to have the option to burn mpegs to dvd with a push of the button. so look!

just some advice... I being doing dvb stuff now with theses dvb cards for a few years now.. once you get this up and running in gb pvr there going to be no simple way to burn a compliant dvd easily... from a user interface of gb-pvr. it is amassive undertaking just on the desktop alone

DVB recordings is full of DVD copyright protection routines, frame rate switch, interleave switching between progresive, video black holes.. the only thing that is consent on dvb is the audio stream.. as soon as you demux it you will find that your video could be 10 minutes shorter then your audio.. and if they are not copyright protected, they have dvb frame size which is not dvb standard 588 X 480 or 640 X 480 or a some other strange size

you should just do it as simple a possiple... burn it udf dvd and be done with it.. may be incorperate mpeg editor such as this one

so you can cut the beginning or ends off or remove commercials or correct audio problems . but basically you should be able to cut edit and burn a dvd 15 -20 minutes .

ive successfully burnt several mpeg2 videos capture straight from pvr350 using gbpvr (prior vbr audio) and had no problems with sync or anything, fully compliant dvds.

im not going to do any kind of menus, perhaps comskip chapter files or some other form of chapters but basically just several titles or one title on a disc, put it in and it plays, just like normal dvdrecorders.
the mpeg2 stream is 99% ready to be burnt, just needs to be fixed in a few places, its not a huge deal really, my main goal is to burn from a capture mpeg2 file, im not even considering divx or any types of files at the moment.

well ive done it, well burn a mpeg from the command line with all freeware tools, using "PVAStrumento" instead of mpgtx.exe, does the job.
heres what my test result times were like (burning terminator 1 at 3.5GBs on celeron d 330 2.67ghz)
1. PVAStrumento : 5 mins
2. mplex :7 mins
3. dvdauthor : 8 mins
4. mkisofs : 5 mins

TOTAL = 25mins + burn time.
im pondering putting all of this into a batch file, since i might just add first two steps to the onrecordingdone.bat (i forget the name ) to the time in about half. and also so you could use nero instead of mkisofs so you could also cut about 5-10mins of aswell, since nero just burns it with needing an iso.

so if first two steps are done after every recording, and using nero it will take around 10mins+ burntime for 4.7gb dvd. which i can live with. ill just have to figure out how to do chapters, since well at the moment there are none and on my PS2 i have to fastforward which is slow, no goto #TIME#.

i suppose i could split the processes up to convert.bat (which converts every file) dvdauthor.bat (creates the structure) burn.bat (create iso and burn or just burn).

so what are peoples thoughts on this matter?

im going to do more tests on things i want to watch (recording terminator awhile ago, and kinda sick of it, dont want to watch the whole thing again.) just to make sure the files are being converted ok.
