How mux mpg format (MPEG-2 codec) and ac3 format (AC3 codec) in AVI container.
SOLUTION:
Better is make DVD (mpeg2 (HCEnc) & ac3/dts (eac3to)) with DVDAuthorGUI.

Thou shalt not abuse.
You may be able to multiplex MPEG-2 video into AVI (despite the AVI container not supporting some features of MPEG-2 videos, like B frames), but you won't easily find a VfW codec or DirectShow filter recognizing this format in AVI, because it is very uncommon. MPEG-2 video belongs in an MPEG Program Stream or Transport Stream. Maybe in Matroska, because this is a universal container supporting a lot of different formats.
What kind of reason would there be to multiplex MPEG-2 video in AVI? Would you try to edit it in VirtualDub? ... Wrong decision. Editing MPEG-2 video requires different tools, not VirtualDub. -
ffmpeg can do that, but as LigH said, that's not a recommended practice.Originally Posted by Mark22
FWIW, MPEG-1 and MPEG-2 can be wrapped in MP4. Just be careful and make sure you don't feed MP4Box with broken /non-compliant video streams (which are not difficult to find or to create, unfortunately). -
ffdshow includes both DirectShow and VFW "MPEG in AVI" decoders.
Here's an example ffmpeg batch file that can remux MPEG2+AC3 from a MPG file into an AVI file:
You can just drag/drop an MPG file onto that batch file to get a quick remux.Code:"c:\program files\ffmpeg\bin\ffmpeg" -i %1 -vcodec copy -acodec copy "%~d1%~p1%~n1.avi"
The bigger issue is why you want to do this as MPEG2 video in an AVI container is somewhat unusual and many programs can't handle it. -
I wonder why you'd do this ... well, considering the previous responders all know a lot more than I do, I should be wondering too.
Do you have some device that says it accepts .avi files? Just putting mpeg2 and ac3 streams in an avi file won't work in that case. Avi is just a container. It's the audio/video formats that are important. Unfortunately the docs for devices often aren't clear on this. If a device wants .avi files you should use divx or xvid video and mp3 audio generally. -
I found a solution it's MPEG format which support a large number of devices.

Yes, the MPEG Program Stream container (normally named with ".MPG") is pretty widely supported.

Well, ffmpeg uses neither VfW nor DirectShow (both are APIs built in Windows). Instead, it uses libavformat to handle containers and split their contents.Originally Posted by jagabo

I offered him two separate things: Using ffmpeg to remux MPEG2/AC3 into AVI files and using ffdshow to give VFW and DirectShow based programs the ability to decode/play those files.Originally Posted by LigH.de

How to mux .mpg and .ac3 to .vob or .mpg? - Simple stream copy video and audio to container
Which program to use? -
Not to *.vob, as that is reserved for DVD-Video authoring. But to mux to *.mpg from MPEG1/MPEG2 video+AC3/MP2 audio is what every mpg muxer does. Try TMPGEnc, Imago, Manzanita...

To be picky: AC3 in an MPEG Program Stream would possibly not be recognized if it wasn't usual on DVD Video. Without the additional DVD specs, it would just be a substream in the "Private Stream 2" and thus be ignored by software which only and strictly supports MPEG specs, as Dolby Digital does not belong to MPEG. But now that DVD Video is so common, most MPEG PS demuxers will check for PS2 substreams, even if there is no whole DVD structure.
I'd like to add ProjectX.jar and the "ancient" bbMpeg to software which possibly does that. But even IfoEdit could be used to "author" a minimalistic DVD, if the material is mostly DVD Video compliant (IfoEdit doesn't check it very reliably). -
When mux with TMPGEnc (MPEG-2 Program (VBR)) on PC work ok but on DVD player play only video not audio.Originally Posted by Cornucopia
Imago do not support .mpg input. -
"DVD players" are only supposed to play "DVD Video" discs. They are not expected to play anything else; if they do, you are lucky.
Regarding "an application not supporting a format": First learn to separate a filename extension from a file format. Files with the same format may have several different extensions. Files with the same extension may have different formats. Of course, Imago supports MPEG-2 video. It may support it only as elementary stream though, not already multiplexed, which may be solved by demultiplexing it before multiplexing. And it may support it only with one extension, but not another, which could be solved by simply renaming the filename extension.
Only the filename extension tells you nothing about the file format. MediaInfo does, instead. -
Sorry, I have home theater:
When play only .ac3 file work ok full duration
When play only .mpg (MPEG-2) file work ok full duration
When mux this two files: play only video no audio (TMPGEnc) or play only 10min. of movie (Imago)
Is there anything else I can try? -
Author a real DVD structure using IfoEdit, if the MPEG-2 video is DVD compliant.
And why are you afraid of telling us which player you have? -
No problem, I have LG LH-T250SC

You can do it with MPEG Video Wizard DVD 5.0.Originally Posted by Mark22

This good work but output files is 2gb bigger than input files. If I reduce video and audio bitrate, movie loss quality.Originally Posted by LigH.de
I use 4.7gb DVD disc.Last edited by Mark22; 30th Nov 2014 at 07:56.

I don't understand. Simply authoring a DVD Video structure with IfoEdit cannot produce output files 2 GB bigger than the input, because IfoEdit does not recode, only multiplex. There are no controls to reduce bitrates.
