audio - Horizontally show two videos side by side and export to one video -

-

What am I trying to achieve: programmatically (using any type of script) in a video Add different videos where the videos are both side-to-side and the sound shown along with the video is played

I get at least two ways from which I can display on two videos side , But in every one I have a different problem which is the process Makes it difficult to complete:

  1. Avisyth and Avs2Avi:
    Avisyth actually makes the process easy, such a simple untrusted script You should be able to play on behalf of two videos:

    video1 = AVISource ("d: \ file1.avi")
    video2 = AVISource ("D: \ file2. Avi ")
    stackhorizontal (video 1, video 2)

    A new output file can be made with AVS 2V.

    The problem here is that I Avisyth is also an AVI with The file is not able to play because I get the message "Could not get a decompressor message for AviSource fourcc xvid" message. I wentogled for the solution of that problem but nothing helped. Jaspot says that I need all the codecs and it seems that I can not do anything. Because I can not get to play the real video, I do not know the final video tells both videos. Avisyth is installed correctly and I am able to run the following script StackHorizontal (version, version).

  2. ffmpeg
    Works like a magic with two video and final file but I do not get the sound from both videos, but only the first one knows me Let's find that the solution to add sound to the second video will be using the envelope in the command line:

    ffmpeg exe -i video1.mp4 -vf "[ In] scale = iw / 2: ih / 2, pad = 2 * iw: ih [left]; movie = video2.mp4, scale = iw / 3: ih / 3 [right]] [left] [right] overlay = Main_va / 2: 0 [outside] "-C: an envelope-B: output of V768.mp4

    But I always get an error that does not get the encoder envelope. I downloaded libfaac.dll but still have no results.

    Is there one solution to these problems? Is there another way to create a video from two programming videos that are played on one side? thank you in advanced.

    Using Avisynth is not a problem for you, you can use just another source Are filters. The bill should fit very well - it is completely standalone and avoaries are not dependent on any system decoder.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
