Record to MPEG2

[build]

G'day All,
Is it possible to record to MPEG2?

I noticed there is an MPEG2 decoder listed in >Settings >Decoders but I can't figure out how to use it.

Thanks in anticipation,

Sorry, NPVR is based on ts file recording. You can record in ts and post process convert it to what ever format you like, but can't directly record to .mpg.

NPVR is based on MPEG2 and needs MPEG2 decoders. The confusion with some people is that the the MPEG2 is now saved in an MPEG-TS container and not MPEG-PS.

build, perhaps it would help if you explain what you are trying to accomplish.

if you want your recordings to end up as an mpeg-2 program stream (.mpg) instead of an mpeg-2 transport stream (.ts), then you could remux the file with ffmpeg in your NPVR/scripts/postprocessing.bat file.

G'day Johnson,
I want to convert the .TS to MPEG-2 and edit the video and burn to DVD.

Could you post an example of postprocessing.bat? I'll see if I can chase up the command line for winFF.

Thanks,

Actually,
Can you help me with a batch file to run winFF (or ffmpeg) AND comskip but I want to keep the original TS till i'm sure it's all working.

or
A pointer to a thread on the subject.

I suppose something along the lines of:

PostProcessing.bat:

Code:

\path\to\ffmpeg -y -i %1 -vcodec copy -acodec copy -f vob "%~dpn1.mpg"
cd \path\to\comskip
comskip "%~dpn1.mpg"
rem del %1

You would just remove the 'rem' from the del command when you want to start deleting the .ts file. NPVR will auto-detect the new .mpg file and use it in place of the missing .ts file.

Now that above is just a simple remux. Depending on your source, the resulting file may not be very dvd compliant. Your dvd authoring program may want to transcode it, or reject it if it requires a completely dvd compliant file. If it can transcode the file anyway, it may be just as happy with the original .ts file.

If you want to actually use ffmpeg to transcode into a proper DVD format file, you'd have to read up a little on the ffmpeg command format. I *think* maybe you can just leave out the -acodec copy and -vcodec copy parameters, and then it will transcode using the proper codecs for and resolution for dvd. I don't use ffmpeg much though, so that may be a misunderstanding on my part.

edit: you may also need to specify a valid DVD resolution with the -size parameter, and probably specify a reasonable bitrate with the -b paramter as ffmpeg defaults to a very blocky 200kb/s.
