I am a beginner who has a move file in ac3 audio format and mpeg2 video format. mplayer can play the video with no hassles. Although Windows media player will not play the audio, which is why I would like to encode this file into a format that can be played anywhere no matter which codecs are present. I am assuming the file will be big as this will lose all forms of compression, but are there any other disadvantages?I am not familar wit encoder to even know where to start.I tried the following:C:\mplayer\1.0rc2>mencoder C:\goat.mpg -o goat.avi -of avi -ovc raw -oac copyThe output was not what I expected. The video would hardly move, and the sound was all distorted with plenty of jitter.Can anyone help me ? I am trying to achieve good quality output.Thanks _________________________________________________________________ Search for local singles online @ Lavalife - Click here http://a.ninemsn.com.au/b.aspx?URL=http%3A%2F%2Flavalife9%2Eninemsn%2Ecom%2Eau%2Fclickthru%2Fclickthru%2Eact%3Fid%3Dninemsn%26context%3Dan99%26locale%3Den%5FAU%26a%3D30290&_t=764581033&_r=email_taglines_Search_OCT07&_m=EXT

You need to do something with the video.. I wouldn't expect "raw" to be a fun direction to take things for your video codec. Probably will use a few hundred gigs/hr of video. Try running mencoder -ovc help to get a list of video codecs you can try. I'd suggest trying something like: mencoder C:\goat.mpg -o goat.avi -of avi -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=3000 -oac copy Similarly, you can run "mencoder -oac help" to get a list of audio codecs to try rather than "copy", though I'm going to guess "copy" will be fine for now. At some point you may want to use "lame". This is a pretty basic answer for you, but your question is also pretty basic. You should be able to find some great example usage in the documentation or if you google for it. Does that answer your question sufficiently? mencoder C:\goat.mpg -o goat.avi -of avi -ovc raw -oac copy On Wed, May 21, 2008 at 9:36 AM, B K <b.kot@hotmail.com> wrote:

To play on a Windows XP fresh install, you need to use msmpeg4v2 as the video codec (on lavc) and probably libmp3lame audio will do. You can try using wmv2 for video and wmav2 for audio, but you will need to mux them on a asf container with lavf. That forbids you from using bframes, unless you use ffmpeg directly. So you could try something like this: mencoder -ovc lavc -oac lavc -of lavf -lavfopts format=asf -lavcopts \ vcodec=wmv2:acodec=wmav2:<other options> <input> -o <output>.wmv
I've used your recommendation, but the quality is very poor compared to the original. How do I ge the same quality ? Cheers,

You can't play a file with "no" codec, you need something :-) I think you want to be sure that anyone can play your file, without needing to install unusual codecs right? It seems that most installations can already play mpeg2 because it's the DVD format, so I don't think you need to change the video. I have tried to find which of the many newer, better codecs are normally available with a Windows installation, and the answer is "none of them". Youtube gets round this by including the codec capability in the flash player. I suggest you try leaving the video unchanged, but switch the audio to something old and common such as mp2. Here is my suggestion: mencoder C:\goat.mpg -ovc copy -oac lavc -of mpeg -lavcopts acodec=mp2:abitrate=224 -o goat_converted.mpg (Note, I have not tried this, so apologies if there are typos...) Translation: mencoder C:\goat.mpg -o goat_converted.mpg (command, input file, output file) -ovc copy (output video codec: just copy what's in the input) -of mpeg (make an mpeg file "container" i.e. the headers etc.) -oac lavc (use lavc as the audio codec) -lavcopts (set options for the codec) acodec=mp2:abitrate=224 (use mp2 for the audio, at a bit rate of 224 kb/s) -- Andy

Uh, MPEG-2 (unless actually on a DVD) is actually one of the formats that very, very few people will be able to play. As someone else has said, really generally playable needs MPEG-1 in MPEG container. For Windows only, WMV/WMA in ASF is another possibility (though might be problematic with Win9x and WinCE if you care about those). Greetings, Reimar Döffinger
I saw somewhere an example where a video was transcoded to flash - maybe that'd be helpful for your purposes - would it be acceptable if users opened their video in a browser that first told them to go install flash?

Apparently you're right, which I find astounding - why should it matter if it's "actually on a DVD" or not? Is the stream decoded in the DVD drive or the graphics card???
As someone else has said, really generally playable needs MPEG-1 in MPEG container.
Indeed. And as someone else suggested, the quality/download-hassle balance may be turning in favour of flash at this point. The only thing is, I'm not sure how many people could actually play a standalone flash movie file, as opposed to something embedded in a web page. -- Andy
Well, what I was suggesting is that you provide a webpage that embedds the flash video in a page that just runs out of some folder. Hence, you store your video and webpage in a folder, zip the folder and send it to whomever. WinXP will be able to unzip a basic zip archive - so that won't be a problem. It mostly just relies on their browser being able to tell that it needs to go get the flash player - I guess you could always just include a hyperlink in the page for that purpose.
