rtJPEG -> mpeg2

[bruce1271]

Does anyone know how to have .nuv (nuppelvideo) be trancoded into mpeg2?

I have a 1 8 Gig file I woudl like to turn into a 2 gig mpeg2.

I am using mythtv

Any ideas?

[mean]

Transcode or avidemux2

[bruce1271]

Thanks,

You wouldnt happen to know which commands in transcode actually do it do ya? I keep getting..
Autoprobing source filname.nuv FAILED.import format unknown.

Any ideas?

[mean]

The problem with mythTv nuv file is that they may be or not vanilla nuv
file. I don't know if transcode supports the extended nuv file.
Avidemux2 is then your best option, it should read all nuv variant.

[bruce1271]

thanks for the suggestion. I can read it in now, but the documentation isnt very clear.

have you used this tool? Do you have any scripts to output mpeg2 from .nuv?

thanks in advance.

[mean]

Yes, in fact i wrote it :)

Select SVCD or DVD as video codec (vcodec button)
Configure -> Set your wishes
Set vprocess to on
File ->save foo.m2v

You will find a (small) tutorial here
http://fixounet.free.fr/avidemux/doc/en

Ps: Don"t try VCD on 2.0.18 it is bugged

[bruce1271]

Great..you are the man. I would like to script this. Is there any way to do it without the gui? Also, How do I output mpeg2?
I tried reading the doc, but I cant seem to find the right commands. I started with the example tutorial, but the audio.m2p never got wrote out.

Here is what I did:
avidemux2 --load ../myth_videos/1067_20031129093000_20031129100000.nuv --audio-process --audio-normalize --audio-resample --audio-codec MP2 --audio-toolame audio.mp2


any ideas. I just ignored the gui. Is that ok?

[mean]

It should be something along
avidemux2 --load foo.m2v --audio-process --audio-resample --audio-bitrate 224 --audio-toolame foo.mp2 --quit


But you just found a bug (Fixed in cvs if you dare to try :)

On the other hand, this will work
avidemux2 --load /work/samples/2mn.avi --audio-process --audio-resample --audio-bitrate 224 --audio-codec MP2 --save-uncompressed-audio /tmp/foo.mp2

but with an audio codec a bit inferior to toolame

[bruce1271]

I dont have an m2v to load. I only have a mythtv .nuv as my start point.
I want to have a .m2v as my output not input.

Can you be more explicit as to what files are input/output to turn a mythtv .nuv into a working mpeg2 file I can play on my dvd player.

what bug did I find?

I dont have cvs set-up. Can I download a new version?

you have to understand I am new to video/audio codec's in general. I have been using linux for 4 years, but never really got into video/audio manipulation.

thanks.

[mean]

It was an example ( i tried it to be sure it was working)
The bug is --audio-toolame is now working when called from command line


Replace foo.m2v or 2mn.avi by you input file xxxx.nuv

One you have the audio ditto for video

avidemux2 --load yourfile.nuv --video-codec DVD --video-conf cq=10 --video-process --save foo_dvd.m2v

But you'd better do it once with the UI

Afterward mux them with mplex, and you will have a DVD compliant mpeg file, ready to be handled by dvdauthor

thank oyu sir. It seemed to have worked, but now I get this error:

Mean,

thanks a ton for your help. It appears to have worked. the audio is synced perfectly.
Only a few issues remain.

1) The audio is synced but the volume is very low. Anyway to fix this?
2) How can I write out a command file based on the options I select through the gui? That would be nice to do. I didnt do any edit, just setting bitrates and things like that would be useful to do from the command line.

thanks again!!! I will spread the word over at mythtv on your program if you wish.
