  • Why does this gstreamer pipeline stall ?

    - by timday
    I've been playing around with gstreamer pipelines using gst-launch. I don't have any problems if I just want to process audio or video separately (to separate files, or to alsasink/ximagesink), but I'm confused by what I need to do to mux the streams back together using, say avimux. This gst-launch-0.10 filesrc location=MVI_2034.AVI ! decodebin name=dec \ dec. ! queue ! audioconvert ! 'audio/x-raw-int,rate=44100,channels=1' ! queue ! mux. \ dec. ! queue ! videoflip 1 ! ffmpegcolorspace ! jpegenc ! queue ! mux. \ avimux name=mux ! filesink location=out.avi just outputs Setting pipeline to PAUSED ... Pipeline is PREROLLING ... and then stalls indefinitely. What's the trick ?

  • motion computation from video using pyglet in python

    - by kuaywai
    Hi, I am writing a simple motion detection program but i want it to be cross platform so im using python and the pyglet library since it provides a simple way to load videos in different formats (specially wmv and mpeg). So far i have the code given below which loads the movie and plays it in a window. Now i need to: 1) grab frame at time t and t-1 2) do a subtraction to see which pixels are active for motion detection. any ideas on how to grab frames and to skip over frames and is it possible to put the pixel values into a matrix in numpy or something directly from pyglet? or should look into using something other than pyglet? thanks kuaywai import pyglet import sys window = pyglet.window.Window(resizable=True) window.set_minimum_size(320,200) window.set_caption('Motion detect 1.0') video_intro = pyglet.resource.media('movie1.wmv') player = pyglet.media.Player() player.queue(video_intro) print 'calculating movie size...' if not player.source or not player.source.video_format: sys.exit myWidth = player.source.video_format.width myHeight = player.source.video_format.height if player.source.video_format.sample_aspect 1: myWidth *= player.source.video_format.sample_aspect elif player.source.video_format.sample_aspect < 1: myHeight /= player.source.video_format.sample_aspect print 'its size is %d,%d' % (myWidth,myHeight) player.play() @window.event def on_draw(): window.clear() (w,h) = window.get_size() player.get_texture().blit(0, h-myHeight, width=myWidth, height=myHeight) pyglet.app.run()

  • Regarding BMA-150 Acceleration sensor

    - by vinaykumar
    Hi all, At present i am working on hal part of sensors in android sdk, we are using 3- Axis BMA-150 Accelerometer sensor to get acceleration values with respect to X,y,Z Axis, I want to know whether this sensor will give o/p directly in SI units by using some calibration techniques or what ? , and i noticed that in sensor.c file they mentioned 720.0 LSG = 1G(9.8 m/s2), what is the relation between LSG and acceleration due to gravity? what is meant by LSG why they are multiplying the o/p of accelerometer x,y,z valuse with 9.8/720.0f . please help on this part . Thanks Vinay

  • Recommendation for screen video capture for demos

    - by Simon
    I am just in the process of making some little demo tutorial videos for my app to help users get up to speed. I have used Camtasia in the past but don't really like it. Anyone have any recommendations. Good is more important than free, but free certainly helps. I can use Windows or Mac for this job.

  • Video Synthesis - Making waves, patterns, gradients...

    - by Nathan
    I'm writing a program to generate some wild visuals. So far I can paint each pixel with a random blue value: for (y = 0; y < YMAX; y++) { for (x = 0; x < XMAX; x++) { b = rand() % 255; setPixelColor(x,y,r,g,b); } } I'd like to do more than just make blue noise, but I'm not sure where to start (Google isn't helping me much today), so it would be great if you could share anything you know on the subject or some links to related resources.

  • Open source Mac video streaming server solutions?

    - by John Wright
    In my application, I want to stream videos shot on an iPhone, *.movie files, from a server running on a Mac desktop to an iPhone or iPad client. What are some possible open source servers that do this that are small enough to be shipped or embedded with a downloadable Mac app? There is a product StreamToMe by Matt Gallagher that does this. I noticed a lot of open source alternatives like ffmpeg, VideoLan, and the like but I not sure which one would be good for the Mac.

  • Multiple video overlay - need advice

    - by Marvin
    Hi, I'm working on a project and I need some advice. Just some background, Im not a programmer though at times I do some fiddling and I am generally comfortable with more specific terms. Now for the actual issue, I have a folder with 10 small videos (4/7 secs max each) and I would like to display them full screen looping and overlaid. I'm not too sure on at what should I be looking at, I thought maybe processing but my most serious issue if that I cant even ask for help since I don't know what I need. Thank you for your time.

  • Video Synthesis - Making waves, pattern, gradients...

    - by Nathan
    I'm writing a program to generate some trippy visuals. My code paints each pixel with a random blue value which loops at 0.04 second intervals. for (y = 0; y < 5.5; y += 0.2) { for (x = 0; x < 7.5; x += 0.2) { b = rand() / ((double) RAND_MAX); setPixelColor(x,y,r,g,b); } } I'd like to do more than just make blue noise... but my maths is a bit rusty, and Google isn't helping me much today, so it would be great if you could share anything you know about making waves, patterns, gradient animations, etc or links to such material.

  • TDD/BDD screencast/video resources

    - by Ree
    I've recently finished watching the Autumn of Agile screencasts and I'm looking for more material of similar scope. Basically, I'm looking for screencasts that present TDD/BDD process while developing somewhat "real life" applications (or parts of them) - so no 20 minute intros please. I'm surprised not to find anything like that though. If you know of any resources that fit the requirement, please list them.

  • Android Convert Video To MP4

    - by Isaac Waller
    I have a Android app. It recieves videos in .flv format which is unplayable by the Android phone. I was wondering how to convert the file to MP4. I could use FFMPEG, but I do not know how I would get it onto the phone, and how it would work on multiple phones if it was compiled for a single one.

  • Which set(s) of video lectures for computer science?

    - by SebKom
    As most of you know a couple of top universities (MIT, Stanford, etc) around the world are now publishing videos of their lectures online. I am advancing to the third and final year of my computer science degree this September and I was thinking about spending some time during the summer to watch a couple of lectures, in order to improve my understanding of algorithms, complexity, programming, software engineering, etc. Now I don't have infinite time to spend so I can't watch all of the lectures from all of the universities so I was wondering if you could suggest me which sets to watch from each one (something like "Algorithms from MIT", "Programming from Yale", etc).

  • Creating a video chat application for drupal site

    - by Dswabster
    I am trying to write an application for website powered by drupal, basically i would like to create an application only authenticated users are able to use, and users are only allowed to connect with members of the opposite group they are a member of. I have been learning flash builder 4 and learning the basics of actionscript but I am still pretty new to Flash and Flex development. I would like to users to connect using the Adobe Stratus 2 protocol and if possible by authentication on existing site and using membership data from existing mysql database. If anyone could give me a nudge in the right direction on how I should go about creating this application or the next steps i should take, it would be greatly appreciated.

  • Loading remote video (MP4) with SWFObject

    - by Reddy S R
    On my webpage I have a swfobject, from Camtasia, that loads mp4 data through FlashVars like this: <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="640" height="498" id="csSWF"> ... <param name="flashvars" value="autostart=false&content=funny.mp4&color=0x000000,0x000000" /> This works fine when the mp4 is on the same server(, and as a file). But when the file is residing on another server, the problem creeps in. Below is how I modify the flashvars. <param name="flashvars" value="autostart=false&content=http://myxyzsite.com/Private/Media/funny.mp4&color=0x000000,0x000000" /> This article explains how to load files from another server. When I point to this URL (http://myxyzsite.com/Private/Media/funny.mp4) in my browser directly, Open/Save dialog box is popped up. So the file exists. Should I set any HTTP headrs, say Content-Disposition to Attachment?
