The GUI shown in the images is my GUI I am writing, and yes it will split, join, merge, crop, pad, play, preview, sync (visually or audibly), resize, deblock, blur, color adjust(increase/decrease), and more. It is a work in progress so I correct and change as needed when I encounter a problem.
Document (DOCX) for some of the features is at https://files.secureserver.net/0s1H0CP5f5WZAc
You are right in that some Mpeg and MP4 will join one way while other formats and combinations like MP4(video,audio,subtitle) will not so I built in these filters. The combining problem of MP4's was a problem several of my friends had as they tried to Join their 'LEGAL' digital versions of movies that were on a 2 sided DVD. I added this feature for that reason.
The bottom line is the method I suggested works and that is what you asked for. If you have other movie formats or wish to do several at a time then the method must be more complicated or written specifically for that.
All the methods suggested above well beautifully in some instances but cause unwanted problems (as does mine) in other situations such as recoding (if you do not wish), changing formats (if you do not want), wrong aspect (if program specifics set wrong). etc.
I am hoping my utility when completely stable will handle generic uses that can be accomplished by clicking the Exceute button in the right hand pane of my example) or you can change the ffmpeg parameters if you are familiar in the upper window of the right hand panel. This will allow for using and just requesting a modification if problems arise.
Anyway, I'm getting long winded from all the Thanksgiving Turkey I ate but the command line will work for what you wanted to do. I use my utility now to arrive at the correct command line that works for most of my uses.
UPDATE: Just tried WMV!/2 and WMA1/2 WMV videos and they join with the command line/Text file I suggested earlier. They MUST be complete files formatted correctly. As mentioned earlier, if it is a clip that is just cut out without rebuilding, it most likely will need reencoded first.

it's the same as "avidemux" worksOriginally Posted by Budman1
I try 1.mp4 + 2.mp4 but part two (2.mp4) in output.mp4 without video, only audio... (I tried mp4box, avidemux, ffmpeg)

The problem with joining MP4 files with the '+' method is that it will 'ABUT' the 2 files as separate with complete headers. If you run AtomicParsley against it to display the 'Atoms' of the MP4 container and show something like: (excess lines removed for bevity)
Atom ftyp @ 0 of size: 20, ends @ 20
Atom moov @ 20 of size: 13148, ends @ 13168
Atom mvhd @ 28 of size: 108, ends @ 136
Atom trak @ 136 of size: 9164, ends @ 9300
Atom tkhd @ 144 of size: 92, ends @ 236
Atom mdia @ 236 of size: 9012, ends @ 9248
Atom ftyp @ 9357369 of size: 20, ends @ 9357389
Atom moov @ 9357389 of size: 13148, ends @ 9370537
Atom mvhd @ 9357397 of size: 108, ends @ 9357505
Atom trak @ 9357505 of size: 9164, ends @ 9366669
Atom tkhd @ 9357513 of size: 92, ends @ 9357605
Atom mdia @ 9357605 of size: 9012, ends @ 9366617
Notice the 2 MOOV Atoms that are each a separate file that you add. Some Players will play this and convert but some will not.
------------------------------------------------------
A better way to do this is with the 'Concat' method by adding the files to a txt file called something like 'filelist.txt'
Then use the FFMPEG concat script shown earlier. This will produce a complete MP4 with one MOOV but several TRAK that should work correctly:
Atom ftyp @ 0 of size: 32, ends @ 32
Atom free @ 32 of size: 8, ends @ 40
Atom mdat @ 40 of size: 18688098, ends @ 18688138
Atom moov @ 18688138 of size: 25240, ends @ 18713378
Atom mvhd @ 18688146 of size: 108, ends @ 18688254
Atom trak @ 18688254 of size: 18018, ends @ 18706272
Atom tkhd @ 18688262 of size: 92, ends @ 18688354
Atom edts @ 18688354 of size: 36, ends @ 18688390
Atom trak @ 18706272 of size: 7008, ends @ 18713280
Atom tkhd @ 18706280 of size: 92, ends @ 18706372
Atom edts @ 18706372 of size: 36, ends @ 18706408
The video I used was approximately 9MB and you can see in the concat method it shows one complete MOOV file with 2 copies (which I used) for approximately 18MB.
This method works for MP4 that are formatted identical without subtitles. If you wish to join subtitled MP4's, then the method is, again, a little different. -
ffmpeg joins 1.mp4 and 2.mp4 when duration of two video are the same - 1.mp4 (40mn 51s) and 2.mp4 (40mn 51s)
joined.mp4 - videoplayer play it nice (all video)
----------------------------------------------------------------------------
but when duration is different - 1.mp4 (38mn 35s) and 2.mp4 (38mn 38s) - it's only 3s...
joined.mp4 - videoplayer play only first part (1.mp4), two part (2.mp4) without video, only audio...
Duration of videos is a big problem?Last edited by user155; 6th Feb 2015 at 03:42.

Hi ,
It works also with :
ffmpeg -f concat -i mylist.txt -c copy "3_fichiers.mkv"
=== mylist.txt
file 'E:\concat\media_1.ts'
file 'E:\concat\media_2.ts'
file 'E:\concat\media_3.ts'
==============
Cheers .JE SUIS CHARLIE !!! -
Different sized videos will join successfully if:
1. The MP4 ( and others) are formatted THE SAME (size, codec, bitrate, etc.). You cannot join apples and oranges and have it work well.
2. The original, unjoined MP4's are not damaged or unusual in their encoding.
If you get a notice that says a PACKET duration is wrong, it probably is for that PACKET not the video. I have tried on many different length/sized MP4's and they do not have a problem but I did encounter several that had problems and, sure enough, they played well in my player but they were not without encoding problems. After re-encoding to correct, they joined fine.
BTW.. I believe the error in STREAM 1 is the audio.
aazerty, thanks for verifying .TS also works with this method since i am compiling a list of which work with concat and which work with the COPY /B method. -
Please let us know the outcome of your list. Personally, I would use Copy /B only as a last resort (you already mentioned the duplicate/conflicting headers problem).

I've already posted info from Mediainfo:Originally Posted by Budman1

1.mp4 and 2.mp4 (THE SAME)
"Stream 1" possibly = "Id 1" (from Mediainfo) so it's still video stream?Originally Posted by Budman1

IIRC, Ffmpeg counts stream #s starting from 0, so stream 1 would be the 2nd stream. Hence, Audio.
Scott -
right, stream from 0
I see "Duration_LastFrame : -18ms" from Mediainfo
it can be a problem? -
Not sure, but you could always try: demux/extract the streams, remux single streams (if necessary), join individually, and then remux V+A.

I extracted only video from 1.mp4 and 2.mp4:

In case anyone is interested, These are the results of my merges both with ffmpeg and the CMD /b copy method and the results I obtained. Most files were using the AVC video and AAC audio codec except for the MPEG type files that used MPEG2 video and mp2 audio.
MKV ffmpeg=joins ok but first subtitle
MKV copy /b = 2 complete movies but time says only one and plays one
MP4 ffmpeg = joins but loses DVBsubs and srt subs
MP4 copy /b= 2 complete movies but time says only one and plays one
VOB FFmpeg = multiple errors trying to join and aborts
VOB /b works and carries over the DVD subtitles
3GP ffmpeg=joins/ plays fine ... Subtitles ??????
3GP copy /b = 2 complete movies but time says only one and plays one
FLAC ffmpeg= Multiple errors during conversion. Fails (possible bad Flac file to begin with?)
FLAC copy /b = 2 complete movies but time says only one and plays one
MPG ffmpeg=joins/ plays fine. Gives correct time and size. Subtitles ??????
MPG copy /b = Seems to play ok but Time and size is given as only one video.
M2V = Same as MPG
M2V /b copy = Same as MPG
Will post update when I join M2TS from Blu-ray. -
I found a solution to correctly join videos (here: http://superuser.com/a/255566)
Code:ffmpeg -i video1.mp4 -c copy -bsf h264_mp4toannexb temp1.ts ffmpeg -i video2.mp4 -c copy -bsf h264_mp4toannexb temp2.ts ffmpeg -i "concat:temp1.ts|temp2.ts" -c copy -bsf aac_adtstoasc output.mp4 del temp1.ts temp2.ts
