fmp4 to xvid

[Capum]

hello,
the film is avi format and I have to reencode to make supportable for my Divx dvd player. I am going to use avidemux because the latest version is very recent and I am telling you all the story because the flick is in a computer at other place which I am going today, sunday.
question is, as alternatives: Can I use 4cc ? Can I use MediaCoder ?

[Hoser Rob]

I believe any ffmpeg based encoder could handle that codec. Tried winff?

You could also install ffdshow but I am loath to recommend 3rd party codec packs, especially in systems newer than win xp, They take over your system whereas the program should just keep its codecs to itself. Ffdshow isn't the worst codec pack out there by any means but it's known to cause system conflicts.

Isn't fmp4 = FFMpeg MPEG-4 and there fore simply another fourcc for MPEG-4 ASP?
I mean why reencode, if simply changing the fourcc should be enough?

Hoser Rob, Selur, thanks for reply.
Hoser Rob, I am trying to watch this film on the DVD player device. Not in the pc system. For what is used MediaCoder ? — No, I've not tried winff. Have you tried avidemux ?
Selur, yes, if i remember, it's a mpeg4. I agree of getting the simplest way. How do I change the fourcc? I have tried with 'avi fourcc code changer'. I inserted XVID (uppercase) on both 'description code' and 'used codec' - there is no tutorial? and is it true to insert uppercase letters in the box matching both boxes? - but the test I made had no picture, only audio on the TV/dvd player with a burned CD.

By the way, what burn program - pick only one - you recommend?

[Selur]

Most people use lower case for the first one (the description) and upper case for the fourCC. Normally it should not really matte, but some players are a bit picky, see: http://forum.mediacoderhq.com/viewtopic.php?f=2&t=10475.

Typical values for the description and four cc are: MPEG4, XVID, DX50, FMP4

I would try combinations would be:
a. MPEG4 for the description and XVID for the fourcc
if that doesn't work
b. DX50 for both
if that doesn't work
c. XVID for both

Ps.: for burning: ImgBurn

Selur, i read the dvd manual which states the requirements for DivX file. The compatibility of DivX files with this player is limited as follows:
720x576 pixel
The names of DivX files and subtitles are limited to 20 characters.
Extensions of DivX file: ".avi", ".mpg", ".mpeg"
Playable Codec Format: "DIVX3.xx", "DIVX4.xx", "DIVX5.xx", "MP43", "3IVX", "XviD".
Only the playback function is supported with DivX 6.0 in the unit.

If the first one is for description, does it matter what letters, even uppercase, you insert on it ?
I have already tried the (c) you posted, no good. XVID for both, because one dvd i got runs all right and MediaInfo shows Codec ID : XVID, and line below it has Codec/hint: XviD.

Ps.: MediaCoder is a encoder ?

[Selur]

If the first one is for description, does it matter what letters, even uppercase, you insert on it ?

Normally it should not, but some players only accept content with a specific way for the FOURCC and the description. :/
So if you have a content which works simply use the description and fourcc it is using.

MediaCoder is a encoder ?

MediaCoder is a frontend for different encoders.

Be aware, that changing the fourcc and the description will only help if the MPEG-4 ASP content is compatible with your player. The content you use still might use settings which are incompatible with your device. If that is the case you really need to reencode. (but fourcc and description still need to have values that are compatible with your device)

[Capum]

do you need the mediainfo of the file?
First, I will give a try to the combinations you posted then.

[Selur]

To do what?
My intension was to let you know, that reencoding might not be needed and that changing the fourcc (you should simply try all combinations; if you always burn the stuff on a DVD-R, you might want to use a DVD-RW if your player supports it) might be enough, that is all I intended.

To check if mpeg4 asp content of this particular file is compatible with my player.
IF i need to reencode, what program do you recommend/use ?

[Selur]

To check if mpeg4 asp content of this particular file is compatible with my player.

Problem is that I don't know your player, so I couldn't even if I wanted to.

Playable Codec Format: "DIVX3.xx", "DIVX4.xx", "DIVX5.xx", "MP43", "3IVX", "XviD".
Only the playback function is supported with DivX 6.0 in the unit.

Doesn't say much.
Normally, most players have problems with:
a. custom quantization matrices
b. 3point GMC
c. QPEL
d. more than 2 b-frames
e. to high data rates (which violate the vbv values the player supports)
-> post a detailed (= not the normal shortened output) MediaInfo (via command line it '--full' would be the parameter to use, through the graphical frontend there should be some option somewhere to show the detailed/debug output) output and I will look at the video description section for you and tell you if I see something obvious problematic

IF i need to reencode, what program do you recommend/use ?

I normally use Hybrid, but that is aimed for more experienced users.
AviDemux, WinFF or Handbrake would probably be tools I would recommend to try.
(I don't like MediaCoder since I don't like tools installing lots of stuff all around the system.)
There are tons of tools that should be able to convert avi->avi.

[Capum]

mediainfo of the problematic file or a good playback-able file?
*ignore this question*

[Selur]

Best you post detailed infos for both. (each info inside 'code' oder 'quote' tags to keep them readable)

[Capum]

the files are not here in my house computer. they are in another place. but i will experiment mediainfo to get it fast when I arrive there. do you have website where to download a small sample ?

[enim]

Too many responses without media-info or a sample?
Who knows may be the file that OP wanna re-encode already DiVX compatible?

[Selur]

@Capum: A small sample of what?

Btw. a few years ago some folks created a divx test cd to test what a specific player supports, it can still be downloaded over at http://www.mpeg4-players.info/index_eng.php in the Download section.
Other than that you can check the database over at http://www.mpeg4-players.info and https://www.videohelp.com/dvdplayers regarding some additional infos for your player.

@enim: have you even read the posts?

[jagabo]

IF i need to reencode, what program do you recommend/use ?

AviRecomp.

[Capum]

*ignore the sample*
i will post one mediainfo i found on torrent site and you tell me if it's like what you want:
