  1. Im not sure how to play this codec/container

    anyone knows how to convert file extension .mp_ to mp4 or any video file ?
    it uses Mackyplayer.
    https://umemaro3d.miraheze.org/wiki/Category:Mackyplayer_Releases
    this are the video content from umemaro "work in progress"
    If I open it using windows media player, I am able to hear the audio but not see the actual video.

    currently using K-Lite Codec Pack standard
    if this is not allowed, please delete this thread

  2. It seems to be standard MPEG video but the weird part is width : pixel0 / height : pixel0 . Is VLC Media Player able to play it ?

    Mackyplayer Releases use the Mackyplayer container as a method of DRM, and as a way to connect the individual video loops in a release.
    https://umemaro3d.miraheze.org/wiki/Category:Mackyplayer_Releases
    DRM generally means encryption. Dunno more about this.

    vlc played the entire audio and then you will be able to see the start of the video from the last 5secs of the file. weird.
    happens to all file..
    just hope there is a way to convert them to a different video file.

  4. Since VLC can play the video and the audio the files aren't encrypted. The files have the extension .mp? but are MPEG Program Streams -- which is usually .mpg. In all likelihood all you need to do is concatenate all the files into one big file.

    how do I do that.
    how do I mux them all ? format factory cant do the job.

    Use a command like this:
    Code:
    copy /b file1+file2+file3 targetfile
    presumably the first part has the file header. Does this part play or give any further info in mediainfo ?
    Quote Quote  
  7. ffmpeg can also concatenate (join together) individual video files, in case the copy /b doesn't work (which it often doesn't). Try the copy /b first, however, because it's easier.

    the link file that I attached is the intro if that's what you mean.
    the info above is the exact info from klite media info save txt

  9. presumably the first part has the file header.
    As far as I know MPEG files are particular in the sense that they don't have a single header at the beginning, they have multiple headers at regular intervals.
    But those ones seem weird.

    vlc played the entire audio and then you will be able to see the start of the video from the last 5secs of the file. weird.
    Weird indeed.
    Code:
    Duration : 3 s 600 ms
    Time code of first frame : 00:00:01:04
    How long does the audio play for that file ? There's seems to be a mismatch between the actual content and what's reported by MediaInfo, it wouldn't make sense that the video starts in the last 5s of a file that has a total duration of 3s600ms.

    command line. Im sorry but I know nothing about that.
    Too bad, because ffmpeg also works in command line.


    [EDIT] That seems... interesting... O_o

    basing on VLC duration : it lasted for 46 secs . during-in game - the actual audio and video is in-sync.
    Id like to link another clip from the game but that one contains NSFW..

    Perhaps this will work, if it understands the files sequence cnumbers

    i downloaded ffmpeg from that link
    tried opening the files from bin but it wont.
    I dont know how. the readme file doesnt contain instructions

    You open a command prompt and type in the commands. Similar to the copy /b situation

  14. I didn't notice the sample in the first post. It's not a "normal" mpg video. At least the first GOP is corrupt. But Mpg2Cut2 can see and play the video (though there is some minor corruption) but doesn't save properly:

    Mpg2cut2 can concatenate segments if you want to try it yourself (I suspect it wont' work properly though). Or if you can provide the next two files in the sequence I'll see what I can figure out.

    it looks like the intro file is screwed up. the others seem like normal mpeg-1 video 720x480 and play fine. i just changed the .mp_ to .mpg they can be edited/combined in a video editor. they don't seem to be in any sort of proper order though...

    I thought the same with the intro.
    just noticed that the rest have some more info including the actual resolution.
    I did try to changed them to mpg. all of them play the same with the intro where the actual video content will be shown at the last few seconds of the clip.
    I tried converting / muxing with format factory but didnt work.

  18. A few random observations :
    None of those files have a standard MPEG header / signature. A standard MPEG file begins with hexadecimal bytes 00 00 01 BA. Here only the first one begins with something close but not quite right : 02 01 B0 02. MPEG signatures are found within the files however, but at variable offsets (+1228 for mov001, +1635 for mov002...).
    Simply merging the five files doesn't result in a readable file, although it does align the headers at sector boundaries for the second file -- but not for the third.
    ffmpeg doesn't properly recognize the files.

    MKVToolNix doesn't recognize those files.
    mplayer can demux them, but only the audio stream is recognized by MKVToolNix or ffmpeg.
    Avidemux 2.6 can open mov000, and suggests to append the other files. After so doing, the chunks seem to be out of order indeed. It shows a total duration of 01:01:933. Audio and video don't seem to be in-sync, though -- at several points the video suddenly jumps from some part of the action to another, while the audio seems to be continuous (or rather, the discontinuities are located at different spots), and at about 00:56 there's a sound of a zipper opening, while the pixellated c-o-c-k is already out and being thoroughly blown...
    If not appending the files automatically, and rather indexing them separately, then adding them one by one in number order, the result is different : the total duration is 00:31:833, the video doesn't become pixellated (except for the c-o-c-k obviously) when jumping from a segment to another, some parts seem correctly synchronized (there's a pee sound while pee is being peed and a brush sound while a brush is brushing), others not (there's a sound of a c-o-c-k being forced into a not-so-eager mouth while said mouth is shown still empty and half open at this point in time, while the aforementioned brush falls on the hard floor without making a sound). It's all very confusing.


    [EDIT] Tried MPG2Cut2, it shows parts which are not shown by Avidemux.

    [EDIT] Tried MPG2Cut2, it shows parts which are not shown by Avidemux.

    doing it with Avidemux right now.
    how do I get the lossless quality possible with avidemux?
    1060 6gb + i7 3770 with 860 evo
    I also experienced clipping / tearing for 30frames video.
    what filter should I use?

  20. I also tried the command line . copy/b
    Im not sure if this is the same as the above suggestion. but it did combined the files. however it only plays the 1st scene and the rest is just blank.
    avidemux did the job but with some clippings and tearing - here and there.

  21. I tried some things with ffmpeg but it didn't like the files without a frame size in the headers. I found that if concatentated the files starting with a frame that had a frame size I could then work with ffmpeg. So I concatenated with mov002.mpg at the start and then the rest (repeating mov002.mpg in the sequence). The resulting file played with a few different players but didn't seek properly with some of them. I then remuxed with ffmpeg while generating new time codes, and also converted to AVC/AAC MP4 with new timecodes (removing the few seconds of mov002.mpg from the start). Both those files play with most players and seek properly. There is some corruption here and there and the files may not be in the proper sequence.

    Code:
    copy/b mov002.mp_+mov000.mp_+mov001.mp_+mov002.mp_+mov003.mp_+mov004.mp_ cp.mpg
    ffmpeg -y -fflags +genpts -i cp.mpg -c copy -fflags +genpts ff.mpg
    ffmpeg -y -fflags +genpts -i cp.mpg -fflags +genpts -ss 5.133 output.mp4
    pause

    ffmpeg -y -fflags +genpts -i cp.mpg -fflags +genpts -ss 5.133 output.mp4
    pause
    the output that youve shared is more accurate than that one the I got with avidemux.. lots of skips / tearing here and there but somewhat sync with the audio.

    ive been doing researched with ffmpeg


    im not really sure how to find the "Header" or which file got one..
    Im assuming that the intro is supposed to be the header

    Image
    [Attachment 54489 - Click to enlarge]

    if changing the output to mkv or mp4 , i get invalid timestamps
    tried following this https://www.linglom.com/multimedia/combine-mp4-files-using-ffmpeg-windows-without-re-encoding/
    should I rename them 1st as mpg before doing it via ffmpeg?
    should I start on 002 since I noticed on format factory that it has info on its actual resolution compare to the first and 2nd file

  23. I used MediaInfo to determine which header had a valid frame width and height.

    I was unable to get the ffmpeg concat muxer to generate a file that played well. You have to specify ".mpg" for the output extension so it knows you want an MPEG Program Stream. Or you have to specify the muxer you want to use.

  24. MPC-BE x64 plays perfectly your sample mov000.mp_ file, both audio and video, after renaming the extension in .mp4

    you're right !
    wonder why, they are the same mpc classic from klite but didnt play the file properly.
    still, my goal is to merge them all as one without weird tearing / skipping like what I got from avidemux.

    at this point I learned that avi remux doesnt make the output video corrupted.
    only issue now is fixing the time stamps.
    MPCBE report the correct duration but a lot of converting programs cannot read the time duration properly.

  26. btw, Im using mpegstreamclip https://www.videohelp.com/software/MPEG-StreamClip
    apparently it does fix the time codes at the cost of corrupted parts "time breaks" . I guess the number of time breaks corresponds the number of corrupted parts every now and then.
    is there a way to fix time codes / time breaks aside from mpegstreamclip?
    or
    is there a way to fix/ remove those frames/clips on the video during conversion
