But now my need is converting these videos to 3GP. I googled my issue but i couldnt get any solution. How can i do this? Any help will be appreciated. 回答1: I suggest that you use xuggler (java wrapper library for ffmpeg). With their bundled ffmpeg you can test one of your videos with this command. ffmpeg -i input.mov -acodec libamr_nb -ar 8000

iOS frame by frame animation, by script

泄露秘密 提交于 2019-12-07 09:38:43
问题 There are a few SO questions regarding frame by frame animation (such as frame by frame animation and other similar questions), however I feel mine is different so here goes. This is partially a design question from someone with very little ios experience. I'm not sure "frame by frame" is the correct description of what I want to do so let me describe that. Basically, I have a "script" of an animated movie and I'd like to play this script. This script is a json file which describes a set of

问题 Matlab has the following guide to making a movie in avi format. My goal is to be able to play the video in my presentation through powerpoint. nFrames = 20; % Preallocate movie structure. mov(1:nFrames) = struct('cdata', [],... 'colormap', []); % Create movie. Z = peaks; surf(Z); axis tight set(gca,'nextplot','replacechildren'); for k = 1:nFrames surf(sin(2*pi*k/20)*Z,Z) mov(k) = getframe(gcf); end % Create AVI file. movie2avi(mov, 'myPeaks.avi', 'compression', 'None'); I understand this

Take a thumbnail from a quicktime (movie) file

为君一笑 提交于 2019-12-07 00:45:23
问题 Does someone know if it's even possible (in PHP) to take a frame/thumbnail from a quicktime movie on the server? Something like the usual GD thumbnail generation, but for .mov files. note: I'm using dreamhost, so I don't have more than web-panel access to the server. 回答1: Dreamhost provides a shared ffmpeg binary in /usr/bin/ffmpeg, so you should definitely be able to call ffmpeg from php by using the system() or shell_exec() functions. The Dreamhost wiki has also an entry providing

Given a URL to a movie, how can retrieve it's info?

假如想象 提交于 2019-12-06 11:16:30
Under iOS, I need to get the codec used to make the move (H.264, MJPEG and so on), the movies' width and height, the file size, and the number of frames in the movie. I tried using AVAsset for the movie duration and such but the duration was always zero. Same for the width/height. I also tried using a movie player controller but that did not work either (see code below). The docs are a bit confusing and with multiple ways of getting to the same place you can't seem to get to the same spot. Has anyone got the above information working properly? I am sure I am missing a few things but I was

C# Video editor?

痴心易碎 提交于 2019-12-06 06:18:50
问题 I want to make a video editor in C# but, I don't know where to start. What classes should I use? What would I compile it into(MOV, MPEG4, ect)? How would I read them? The most important thing I am looking at though is reading them. 回答1: I want to make a video editor in C# but, I don't know where to start. A video editor is a pretty complex application with many independent subsystems. You will need asset management, a timeline, a player component, video and audio effects and filters, title

PHP function/library to create screenshot from movie [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center . Closed 7 years ago . I have a site where users upload movies (MP4, FLV, OGV). I need a PHP function to generate a poster/screenshot in JPG automatically from an uploaded movie. The screenshot should be for the opening scene of the movie. If it is a javascript utility (rather than PHP), that will be fine too. I can't find anything.

Automatic saving a figure as an image file in Matlab

試著忘記壹切 提交于 2019-12-05 19:39:40
I'm creating 49 figures in Matlab, they are all created automatically one after the other. I want them to also automatically be saved as .tif or .jpg images with names corresponding to their figure number. Can I do it? And if so,how? the code for the creation of the figures is: for num_picture=0:48 ... figure (num_picture+1) imshow (screen_im) end The ... part is where all the calculations of screen_im are. I want those images in order to create a movie from them, If there is a way where I can create the movie automatically form Matlab, it would be good also, actually it will be better. You
