| mencoder is very useful for converting between different container formats. It is a command line tool so it is not super easy to use for us lazy newbies. :)
How to convert from OGM to AVI or MKV to AVI with mp3 audio and leave the video source intact. If the OGM or MKV already has a video that can be stored in AVI like DivX or XviD you only need to copy it. Use gspot to identify the video codec in the ogm,mkv. How to convert from OGM to AVI or MKV to AVI with mp3 audio and xvid video. If you want to convert the audio to mp3 and the video to xvid in an avi.

| Here are a few questions with this:
How do I use it for a file with multiple audio tracks? And just how big can the file you are converting can be? What are the commands that would allow me to launch or save it to a different drive? Thanks. I always come here for my conversion needs. | ||||||
| Baldrick posted 2005 Jun 15 10:37 | ||||||
No idea, it is probably possible but I haven't done that much mencoding.
Adjust the bitrate, use a bitrate calculator to calculate.
Change the drive letter, like d:\video.avi | ||||||
| celtic_druid posted 2005 Jun 15 20:30 | ||||||
| Use -aid # or -alang eng if it is tagged properly to specify which track to convert. The second track you would have to process seperatly like say.
mplayer -ao:pcm:file=track2.wav -vo null -vc dummy -aid 2 input.mkv To extract the 2nd stream, then use mencoder with -aid 1. Also use -lameencopts to change lame settings. -oac help for a list of audio compressors (pcm, ac3, etc.). -ovc help for a list of video codecs, including lossless ones. Check the docs over at mplayerhq for full details. | ||||||

| celtic_druid posted 2005 Aug 12 23:09 | ||||||
| mplayer can demux subtitles by using say the -dumpsrtsub if they are textsubs or -dumpsub for vobsubs. See mplayer man for full details/options. Not sure if mencoder can mux subs to avi though and even if it could, external subs are more compatible anyway.
Could also just demux the subs using mkvextract. | ||||||

| i am trying to use this method to convert an mkv to avi. the source uses the h264 video codec, and the audio is aac (i have both codecs installed). when i combine the video and audio streams into the avi, there is an error in the output file (frame 568). this glitch is not present in the source files, they play perfectly, while the output file crashes what ever player i use, as well as virtual dub when i attempt to put subtitles in it. does anyone know what might be causing this? | ||||||
| celtic_druid posted 2005 Oct 10 22:32 | ||||||
| Copying native AVC to an avi could be the problem. Not really a good idea at any rate. Does the mkv use native AVC or VfW compatibility mode? Also how are you testing playback? With mplayer or something else? | ||||||
| chaos_maiden posted 2005 Oct 10 22:41 | ||||||
| the mkv is vfw mode. i'm copying the video stream and converting the audio to lame mp3 (i normally use virtual dub mod, but it doesn't support aac audio). i've tried playing the file in both real player and windows media player, as well as loading the file in virtual dub, all 3 result in a program crash when it gets to that particular frame. in media player, i get an error message saying that there is an assertion error in the C++ runtime library and gives the file path for the h264 codec in ffdshow. is it possibly a problem with ffdshow? | ||||||
| celtic_druid posted 2005 Oct 10 23:52 | ||||||
| Try playing it with mplayer.
If the mkv uses VfW for the video (not recommended or spec compliant for AVC) then remuxing to avi should be fine. What build of ffdshow? | ||||||
| chaos_maiden posted 2005 Oct 11 00:59 | ||||||
| it doesn't play in mplayer either. i tried another mkv with the same encoding on the streams and it behaves the same way. i'm using the 9/20/05 build of ffdshow. | ||||||
| chaos_maiden posted 2005 Oct 11 19:47 | ||||||
| mencoder also crashes if i try to re-encode the video to xvid during the initial pass, however both the source mkv and the extracted avi stream (i used mkvextractgui for the extraction), which also use the h264 codec, playback with no problems in any player | ||||||

| I've been using Mencoder coder for some time now, tho I only use its most basic of commands (ripped from this site :roll: ). Thanks for all the posts, BTW!
So, this may sound stupid, but is lame's mp3 encoder its default audio encoder? Is there any other way to change the audio encode to like, say, good ol' wav.? | ||||||
| sakuya_su posted 2006 Feb 14 04:19 | ||||||
| audio codecs are selected using the flag -oac CODEC name, look on the manual of mencoder for a list of codecs | ||||||
| celtic_druid posted 2006 Feb 14 04:19 | ||||||
| Default I think from recollection was libavcodec 224k mp2. Now if you don't sepecify an audio codec, I think you will find it asks you to and won't encode.
Sure for PCM (assuming that is what you meant by "good ol' wav") it is just -oac pcm. Errr, on second thought, I don't think it ever had a default audio encoder. You always had to specify one, just that if you do -oac lavc, you get 224k mp2. | ||||||
| KIJIN posted 2006 Feb 14 06:34 | ||||||
| K. Got that part at least.
Hope you guyz don't mind another question. I think (correct me if i'm wrong) that you can imbed subs on the avi file using mencoder. But I keep running into the same problem.

Maybe the font path is wrong. Please supply the text font file (~/.mplayer/subfont.ttf). subtitle font: load_sub_face failed. The conversion works. But, no subs still. I didn't find a /font directory in the mplayer directory. Do you have to DL another specific true type font file for it to work? Or did I use the wrong command? Sorry to bother ya guyz. | ||||||

| Ok, before I get to my own issue: Kijin, if you haven't been able to fix your issue yet, I'd suggest using the method described in this topic: http://forum.videohelp.com/viewtopic.php?t=272736
But anyway, I have a rather nasty mkv file that I'm trying to convert to avi. It has h264 video, which is ugly, but I can deal with that, but the audio format is DTS. I have downloaded the newest version of ffdshow, which has DTS support, but mencoder still won't encode this file. I've also tried extracting the streams and using virtualdub, but mkvextractGUI doesn't support DTS and therefore won't extract the audio stream. Does anyone have any ideas on this? | ||||||

| EwanG posted 2006 Sep 05 14:19 | ||||||
| Just a tip from someone who has been getting WAY too involved with Mencoder and FFMpeg lately (I have a couple Tivos, a PSP, and like Anime..) - If you have an MKV that you are trying to decode directly with ffmpeg, make sure to get the MKV patch from the maillist and rebuild ffmpeg with that.
Alternately, use mencoder first, and then ffmpeg. As long as you use high quality settings, you will not see that much difference from going through the double-step. In fact, using ffmpeg without mencoder first on many MKV and OGM files will leave you with a somewhat "jerky" video. If you have more than one audio stream, for ffmpeg you want: -map 0:0 -map 0:2 if you are using the first video and second audio stream. For mencoder, however, you'd want: -aid 1 because mencoder starts counting at 0. In both cases, the argument should be right after the input filename. Hope this helps other folks as much as this thread has helped me. | ||||||

Probably not a good sign.
Definately not a good sign since it seems to be saying that it dumped everything from frames 416 to 4644... I'd see if fixing the first option (i.e. make sure you get compatible releases of mencoder and MPlayer) might not fix the second. FWIW, Ewan | ||||||

| Well I upgraded to the latest version of mplayer/mencoder but I'm still having no luck. The errors are gone, but with a different file I get the same results. What's odd is if I break it during the encoding it plays fine, it's only when I let it finish that I get a bad file.
I've tried leaving the audio intact and converting it to MP3. What I did realize is that the resulting file will play in the DivX player, just not in WMP. I need it to play in WMP so I can play it through Media Center in Vista. I don't want to install the CCCP on Vista as it is really buggy with just standard DivX/XviD files and crashed Media Center a lot. I've been using FFDShow on my media center box and that has been very stable. Here's the output I'm getting:
Any other thoughts would be GREATLY appreciated... Thanks, Ross | ||||||
| EwanG posted 2007 Mar 02 09:26 | ||||||
| You're specifiying XVID as your video codec. If you want it to play in WMP you are going to need a WMP friendly codec. Not sure if WMP will let you install the free DiVX codec, particularly in Vista.
Personally, I always use mpeg2 since all of my playback devices support that. However you get some rather largish file sizes doing that. FWIW, Ewan | ||||||
| rosscarlson posted 2007 Mar 02 09:51 | ||||||
| Ewan,
Thanks again for the help, and the quick help at that! I am purposefully specifying DivX as I have ffdshow installed in Media Center and can play DivX just great, including some 720p DivX files that I have. It's just odd that the resulting file will play if I break the encode but not if I let it finish. I'll try MPEG next, disk space isn't an issue at all so that would be fine. Do I just use -ovc mpeg (I'll look after I post this...) Thanks, Ross | ||||||
| EwanG posted 2007 Mar 02 10:52 | ||||||
| Well, "I" run mencoder to get a smooth output from the originating MKV file, and then run ffMPEG to get the final version. So I generally don't try to watch what comes out of mencoder which may or may not relate to the problem you're having. IOW, it's possible I've been having the same problem you're having, but not noticing it because I always run the ffMPEG next, and so only watch the .mpg file.
In my case, I would take the AVI you created with mencoder and then shoot it to ffMPEG with: "c:\program files\ffmpeg\ffmpeg.exe" -i "myfile.avi" -target ntsc-dvd -acodec mp2 -ab 192 -ac 2 -ar 48000 -b 4096 -r 29.97 -s 720x480 -vcodec mpeg2video "myfile.mpg" YMMV, Ewan | ||||||
| rosscarlson posted 2007 Mar 02 11:26 | ||||||
| So what command line are you using for part 1? I'm happy to do both if that will work, of course that will take more time to do both but if the resulting file still looks great I'm fine with that...
Again thanks for all the help... Ross | ||||||

| I'm having trouble with .mkv files with h264 video and ac3 (or mp3 for that matter) audio using mencoder. I try -ovc xvid to convert the video and -oac copy to pass through the audio, and the result in the log file is a "1 duplicate frame(s)" message approximately every half second and eventually a "Too many audio packets in the buffer: (4100 in 2570449 bytes)" message and the process stops. I've tried all sorts of options like -noskip that I've found in my research of this problem, but I still get the duplicate frames. The best I could do was using the -mc 0 option which suppressed all but one "duplicate frames" messages but the end result was the same - the process stopped prematurely.

Any ideas anyone? | ||||||

Hope this helps! | ||||||

| Yup, that's what I'm using but I'm having the same issues that emmgunn is having. The odd thing is if I break it before the output completes the file plays fine.
What version of mencoder are you using, do you know? | ||||||

| In the guide you say to check the codecs in the mkv by opening the mkv in gspot. Well I did this (gspot v2.70) and gspot does not tell you what codecs are in the mkv. What program can I use to check the codecs in an mkv? :?: | ||||||

| I sucessfully converted from MKV to AVI. But!, the only player I can view the movie from is gmplayer.
VLC, Media Player Classic, Zoom PLayer Professional all pause when I select the movie I set audio to MP3. Any ideas why this is happening? Thanks, Louis | ||||||

It seems like your AC3 audio is 5.1, while mencoder thinks it's 128kbps 2-channel audio. I'm interested in doing exactly the same conversion, but haven't found anything that really works for me... | ||||||

| Hi.
I need somebody's help with mencoder. I'm encoding MKV to AVI files using old version alltoavi batcher with option of manually change comand. What I need is how to encode audio track #2 or if it says only languadge kind. Here I have a comand: mencoder "PATH\FILENAME.EXTENSION" -ovc copy -oac lavc -lavcopts acodec=mp3:abitrate=96 -o "PATH\cvt_FILENAME.avi" What and to where should I add some change? | ||||||

| what command would i use to set the bitrate at 384kbps and the resolution reduced from 1280x720 down to 960x528???
thanks jesse | ||||||

| Hi, i have converted a mkv file to avi following the instructions given in the topics first post but when i play the video the audio is out of sync with the video.
Does anyone have any idea how i can fix this? Should i try using a different audio codec? These are the commands i used to convert.

| OK for those having problems as I did with a MKV file that has H264/AVC and AC3 audio.
Here's my command that does work but requires the re-encoding of the audio I'm afraid. mencoder -channels 6 -aid 0 -noskip -mc 0 cdd_x264_hd.mkv -ovc xvid -xvidencopts bitrate=<your bitrate> -oac lavc -lavcopts acodec=ac3:abitrate=<your bitrate> -o test.avi For the person who asked about picking the right audio track if there is more than 1, well in the above example file I have 2 audio tracks and the "-aid 0" option in the above command picks out the 1st audio track of the 2. Hopes this helps people out. If so let me know. Also if anyone can figure out how to get "-oac copy" working without audio sync issues for AC3 I would be glad to know. And if anyone knows how to get mencoder to use multiple threads for use with several CPU's I have 4 of them that would be nice too. Cheers G1ngerNinja UPDATE: Well it turns out that the centre audio channel ends up in the rear-right channel. So what I have managed to do instead is this:- ./mencoder -nosound -noskip -mc 0 s-disturbia/ccd_x264_hd.mkv -ovc xvid -xvidencopts bitrate=<your bitrate> -o ccd_x264_hd_1280_vidonly.avi This gives us the video in xvid format without sound. Then we need to extract the original AC3 audio like this :- mplayer ccd_x264_hd.mkv -aid 0 -dumpaudio -dumpfile ccd_x264_hd_1280.ac3 Then we need to mux the 2 together, I use AVIDEMUX which works a treat. So hope this helps people out. | ||||||

| I am trying to convert an mkv file to an avi file and I am having trouble with mencoder.
I keep on getting a message that the -oac command does not exist. Is there something that I am missing? | ||||||

| do you realistically expect help with the amount of info you provided?
always provide command line used and resulting output. | ||||||

niiice, lets you select language too. been looking for a free program like that for ages, just one problem and question though. converted a video, set it to convert it in english... however now all of the sound is ridiculously out of sync. any idea how i remedy this? if i just play it as an MKV file the english audio is fine, but for some reason it went all out of sync while converting. | ||||||

| I'm using OGG2AVI and the program works great but after burning the new avi file(which played perfectly on VLC Player) I then tried playing it on my dvd player and it wont play the avi file...I've also tried changing the mp3 bit rate both higher and lower....same thing...no luck. Any ideas on how to get this to work? I'm using a Toshiba SD-3990 DVD player. Any help would be greatly appreciated. | ||||||

| fijha: I don't think ogg to avi reconverts to divx/xvid that your dvd player requires. Reconvert using WinFF or alltoavi instead. |
