I'm having an idea to create a Censor Plugin/Extension for VLC Player..
Problem Scenario :
An Adult-Scene for 1 minute in a nice movie makes it not watchable with Family.
My Solution :
Create a Plugin/Extension which does the following
Reads time positions from a file similar to subtitle files
Skip these time positions (which are adult or inappropriate) when playing
Help i needed :
I searched in Google and in videolan website, But can't find an exact solution
Are there already similar Plugins available?
Where should i start?
Please help me if you could guys.. thanks..
Same looking for having/developing Exact same solution. This might be helpful to you.

If you chop random bytes out the movie is likely not playable. The player might crash or fail to resynchronize the stream – the video might just stop. Plus, you're gonna have a hard time figuring out where the "adult" bytes are, so to speak.
If you already know where the parts are that you want to cut out, I would edit the file in any of the numerous video editors. Even Windows Movie Maker or iMovie would do the job, and those are easily available on both major OSes.
This is a requested feature for VLC. Not really anything user-friendly out there. Still, VLC offers the possibility to create playlists in a certain format that would mute or skip parts of a file. This is called XSPF. You might be able to figure out the proper format for this.
Also, there's movie-content-editor:
A VLC based editor built in python that allows users to create and use custom filter files to make movies more family friendly. Allows users to have the player automatically mute specific words or skip certain scenes based on the content of those scenes.
And sensible-cinema:
Clean Editing Movie Player allows you watch edited movies by applying delete lists (EDL's) (i.e. "mute out" or "cut out" scenes) to DVD's/files, with preliminary support for also applying them to arbitrary web/internet based players like netflix instant, hulu/hulu plus etc

Clearplay-like (content filter) module exists?

I am interested in visualizing melodic contours of polyphonic music with Processing. It is still unclear to me, though, what the most convenient format for imported data (pitch and onset/duration) would be: tabular (e.g. Humdrum), XML (e.g. MEI, musicXML), or JSON? Maybe another format?
Any suggestions/thoughts on this would be really helpful! Thanks.
Using MIDI files would be optimal, because of the combination of those 3 reasons
MIDI is widely used. You can export a .midi file from pratically any score editor plus you can create your own by recording the input from a midi instrument.
You can already find .midi files of iconic polyphonic music on the web (Bach's counterpoints, Reinaissance vocal music, etc)
It just contain music/playback information. It doesn't contain notation information like music XML. So if you just want to see pitches and note position/duration (like in this video) then .midi will contain just what you need
You can use the Java Midi Package in Processing and it already contains everything you need to read the MIDI files.
While other formats might also apply for 1, 2, 3 or 4 only MIDI applies for all of them.
The best answer I can give you is that you should put together a simple hello world program that tests out each format and see which one you like the best.
In the end, you're the one that has to deal with the code, so only you can really decide on the best format.
I have a large collection of video files, which have missing atributes like length, resolution, bitrate etc. I would like to fill those out somehow but im not sure what solution to use. It would take ages by hand but i'd rather see if a program can do it first. I tried searching for a solution but didnt find anything substantial.
The reason why, is becuase im trying to filter out the videos by atributes. If a vid is shorter than 30 minutes, i delete it. Can sort with the windows explorer, which cant do that if the atributes are missing.
Since you asked this on StackOverflow and not on SuperUser I'm going to answer this as a programming question.
Those properties are provided by the Windows Property System. It is possible to write your own property provider and overwrite the system default provider registration but this is a fair amount of work if all you want to do is sort some files.
Is it possible to do object recognition of a movie file (mp4, mov,...)?
For example, stream a movie and look for objects or people and determine who the person is or what products are in the movie?
Would the process boil down to taking many snapshots of the image buffer and processing them as normal images?
I am totally new to this, sorry if this question may makes no sense at all.
I found this project which does exactly what I was looking for.

It's done in realtime, so I will review the code.
The VideoPlayer (possibly VideoDisplay also) component is capable of somehow automatically picking the best quality video on the list it's given. An example is here:
http://help.adobe.com/en_US/FlashPlatform/beta/reference/actionscript/3/spark/components/mediaClasses/DynamicStreamingVideoItem.html#includeExamplesSummary
I cannot find the answers to below questions.
Assuming that the server that streams recorded videos is capable of switching across same videos with different bit rates and streaming them from any point within their timelines:
Is the bandwidth test/calculation within this component only done before the video starts playing, at which point it picks the best video source and never uses the other ones? Or, does it continuously or periodically execute its bandwidth tests and does it accordingly switch between video sources during the playback?
Does it support setting the video source through code and can its automatic switching between video sources be turned off (in case I want to provide this functionality to the user in the form of some button/dropdown or similar)? I know that the preferred video source can be set, but this only means that that video source will be tested/attempted first.
What other media servers can be used with this component, besides the one provided by Adobe, to achieve automated and manual switching between different quality of same video?
Obviously, I'd like to create a player that is smart enough to automatically switch between different quality of videos, and that will support manual instructions related to which source to play - both without interrupting the playback, or at least without restarting it (minor interruptions acceptable). Also, the playback needs to be able to start at any given point within the video, after enough data has been buffered (of course), but most importantly, I want to be able to start the playback beyond what's buffered. A note or two about fast-forwarding is not going to hurt, if anyone knows anything.
Thank you for your time.
Is it possible to use the NSSpeechRecognizer with an pre-recorded audio file instead of direct microphone input?
Or is there any other speech-to-text framework for Objective-C/Cocoa available?
Added:
Rather than using voice at the machine that is running the application external devices (e.g. iPhone) could be used for sending just an recorded audio stream to that desktop application. The desktop Cocoa app then would process and do whatever it's supposed to do using the assigned commands.
Thanks.
I don't see any obvious way to switch the input programmatically, though the "Speech" companion guide's first paragraph in the "Recognizing Speech" section seems to imply other inputs can be used. I think this is meant to be set via System Preferences, though. I'm guessing it uses the primary audio input device selected there.
I suspect, though, you're looking for open-ended speech recognition, which NSSpeechRecognizer is not. If you're looking to transform any pre-recorded audio into text (ie, make a transcript of a recording), you're completely out of luck with NSSpeechRecognizer, as you must give it an array of "commands" to listen for.
Theoretically, you could feed it the whole dictionary, but I don't think that would work since you usually have to give it clear, distinct commands. Its performance would suffer, I would guess, if you gave it a bunch of stuff to analyze for (in real time).
Your best bet is to look at third-party open source solutions. There are a few generalized packages out there (none specifically for Cocoa/Objective-C), but this poses another question: What kind of recognition are you looking for? The two main forms of speech recognition ('trained' is more accurate but less flexible for different voices and the recording environment, whereas 'open' is generally much less accurate).
It'd probably be best if you stated exactly what you're trying to accomplish.
