  • How to rip AVI from VOB using ffmpeg

    - by Linux Jedi
    I am trying to convert a VOB to an AVI. I have ripped an AVI from this VOB before using ffmpeg, but for some reason it's not working this time. This is what I tried: ffmpeg -sameq -acodec copy -i VTS_01_2.VOB output.avi This is the output I get: FFmpeg version 0.6.1, Copyright (c) 2000-2010 the FFmpeg developers built on Dec 29 2010 18:02:10 with gcc 4.2.1 (Apple Inc. build 5664) configuration: libavutil 50.15. 1 / 50.15. 1 libavcodec 52.72. 2 / 52.72. 2 libavformat 52.64. 2 / 52.64. 2 libavdevice 52. 2. 0 / 52. 2. 0 libswscale 0.11. 0 / 0.11. 0 [mpeg2video @ 0x101014200]mpeg_decode_postinit() failure Last message repeated 6 times Input #0, mpeg, from 'VTS_01_2.VOB': Duration: 26:30:29.20, start: 140.171311, bitrate: 90 kb/s Stream #0.0[0x1e0]: Video: mpeg2video, yuv420p, 720x480 [PAR 32:27 DAR 16:9], 9800 kb/s, 31.44 fps, 29.97 tbr, 90k tbn, 59.94 tbc Stream #0.1[0xa0]: Audio: pcm_s16be, 48000 Hz, 2 channels, s16, 1536 kb/s Output #0, avi, to 'output.avi': Metadata: ISFT : Lavf52.64.2 Stream #0.0: Video: mpeg4, yuv420p, 720x480 [PAR 32:27 DAR 16:9], q=2-31, 200 kb/s, 29.97 tbn, 29.97 tbc Stream #0.1: Audio: pcm_s16be, 48000 Hz, 2 channels, 1536 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Could not write header for output file #0 (incorrect codec parameters ?)

    Hello All I would like to develop such iphone application that provides functionality to download viedo. i am doing some as below 1) Loading HTML content on web view 2) The loaded html content contains the video link (i.e http://test.com/test.mp4") 3) When i click on that it will play the video in native player. 4) but i would like to prevent this thing and start downloading video from that URL for example, if i click on link it should not open native video player, it should start downloading from that url and store somewhere on iphone (i.e document directory) is there any solution for same? Thanks Vivek

  • Windows-Mobile Directshow: Specifying bitrate/quality of a WMV video capture

    - by Landstander
    Hi- I'm stumped on this, and I'm really hoping someone could point me in the right direction. I'm currently capturing video in Windows Mobile and encoding it using the WMV 9 DMO (CLSID_CWMV9EncMediaObject). That all works well enough, but the output video's bitrate is too high, resulting in a video file that's much too large for my needs. Ultimately, my goal is to mimic the video settings that Microsoft's Camera Capture Dialog outputs in the "messaging" quality mode (64kbps) from my C++ code. Currently, my code's outputting a WMV file with a bitrate of 352kbps. The only example I could find of specifying the capture bitrate with a WMV9 DMO was this. The idea in that code was basically to use a propertybag to write a bitrate to a property of the DMO. Update: In windows mobile, the closest codec property I can find that seems to equate to the bitrate is "g_wszWMVCVBRQuality". Microsoft's documentation of this property is extremely confusing to me: It basically seems to say that a higher number equates to a higher quality, but it gives absolutely no explanation of the specifics for each number. When I attempt to set this property to value like "1" via a propertybag for the WMV9 DMO, I run into a -2147467259 (unknown) error. To summarize: What is the basic strategy to specify the bitrate/quality of a video being captured via directshow (wmv9) on a windows mobile platform? I've heard (or wondered about) the following methods: Use the propertybag to change the encoder DMO's property that corresponds to bitrate/quality (currently failing) Create your own custom transcoder/encoder to specify it. This seems unnecessary since the WMV encoder works well enough- it's just at too high a bitrate. The VIDEOINFOHEADER has a bitrate property, but I suspect that specifying new settings here will do nothing to alter the actual encoding process since I wouldn't think file attributes would come into play until after the encoding. Any suggestions? PS: I would post specific source code, but at this point it may confuse more than it helps since I'm floundering so much on how to do this. At this point, I'm just trying to validate the general strategy. THANKS!

  • HTML 5 video custom controls

    - by pygorex1
    Like many web developers I'm looking forward to streaming video that utilizes the new HTML 5 <video> tag. Browser support definitely isn't wide enough yet, so using a Flash/SWF fallback is a must. This got me thinking: in Flash it's possible to highly customize the playback controls (pause, play, stop, seek, volume, etc.) in HTML 5?. What options are there for customizing the glyphs, icons and colors of video controls? Is Javascript required? For instance the following page renders different controls depending on the browser - tested using FF3.5, Chrome and Safari: http://henriksjokvist.net/examples/html5-video/ It would be really awesome to customize and standardize controls across browsers and even match the Flash controls used by older browsers.

  • Pick video using PhotoPickerPlus?

    - by Anil Katti
    Is there a way I can pick video using photo-picker-plus instead of a photo? When I check the media type using: NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType]; I always get public.image (even when I pick a video). On a related note, is there any other SDK similar to photo-picker-plus for picking video from different sources? UIImagePickerController could be an option. But, I am looking for something that is as versatile as photo-picker-plus. Anil

  • Web P2P video confrence solution

    - by dtroy
    I'm looking for the best possible solution which will allow me to incorporate live video/audio conference between 2 users(only 2 at this point) into a flash gaming platform. The video chat is not just an extra feature, it's the main one. I'm mainly looking at open source implementations or something I'll be able to implement myself, but will consider commercial products if they are exactly what I need. Here are a few things I've looked at, but so far, I didn't find any of them good enough: Flash player 10's P2P capabilities sound promising, but I am aware of the fact that Adobe has not release any information on the RTMFP protocol and that there is no commercial server which supports it at this point. Stream all the video/audio live through a flash server (not p2p), but from my personal experience you don't get a smooth conversation. I think TokBox uses this method Java applets are a possible solution too (to perform p2p), but I don't think it will be a nice and elegant solution to combine them in the game at this point (and requires the user to authorize them). BTW, I couldn't find any useful implementations. So, If you know of any, i'll look into them. Google Gmail Video Chat uses a custom (and proprietary) browser plug-in which does the p2p and streams the video/audio into the flash player. This is a possible solution, but I rather not implement the entire p2p protocol stack + browser plug-in at this stage and concentrate on other aspect of the game itself. I think they are using XMPP based protocol similar to Jingle and they've release a Jingle librarby but without the video confrencing implementation. EDIT: In response to Branden: I am aware of Adobe Stratus. Stratus is a beta, hosted rendezvous service that aids establishing communications between Flash Player endpoints (RTMFP server). This current release of the Stratus is prerelease and is designed for evaluation purposes only. The service is not final. There is no guarantee that the service will continue to exist in the future or any information about the future cost. That's why I don't think it can be used as a commercial solution. At least not yet. I'd appreciate your suggestions and advice. thanks!

  • Generating video or images of geometrical objects from data

    - by Jonathan Barbero
    Hello, I'm working in a course's project to predict the velocity and position of the solar system planets (and other objects). It will be really cool if I can visualize the predicted objects data, if it's possible generating 3D images, if in video that's amazing. Do you know any library that lets me to use this data to generate an image or video? (I don't care in which language) Data: - simulation step (time line step for a video) - positions of the objects - radius and/or colours of the objects Thanks in advance, any suggestion is welcome.

  • Not playing .mov files in WMP, not loading .mov files in Windows Live Movie Maker. What am I missing?

    - by royatl
    My friend needs to create a video and she has some source files that are .MOV format. I assume they are h.264. She can view the files with QuickTime. She has a laptop running Vista, and a just-downloaded version of Windows Live Movie Maker (which I'll call LMM for short). LMM shows an 'X' icon when she tries to add one of these files to it. My machine runs Windows 7 Pro, and a slightly earlier build of LMM and has no problems editing video with these source files. I assume she's missing a codec but what can I tell her? I've looked at the answer that mentions a QuickTime DirectShow Source Filter Plugin. It mentions only playback through WMP, not editing via LMM, but is that what she needs? I didn't have to load anything like that. That project's now done (she punted and used iMovie on a Mac). But I did gain another clue. She could play a 720p .MOV file, but these were 1920x1080 files.

  • SimpleModal bug when positioning HTML5 video

    - by digm
    I am trying to use simple modal to display a modal window containing a video. I'm using the HTML5 "video" tag to do this. Using JQuery and SimpleModal, I can get it working in Chrome and Firefox, but for some reason Safari fails to maintain the centered positioning of the modal dialog for the video. In other words, when you scroll up and down in the windows, the modal window stays in its place, but the video scrolls up and down with the rest of the content outside the window. I've put together a 29 line piece of HTML code that you can cut and paste to test. https://pastee.org/z5sw Anyone know what I can do to fix this? I've been trying for a few hours now and no combination of JQuery, SimpleModal, or CSS changes can seem to fix this. I'd appreciate any suggestions. Thanks in advance!

  • Making a DVD video with a still image and PCM 16bit audio with ffmpeg

    - by João
    I'm trying to make a small video with a still image and a sound file playing in the background to pass it to dvdauthor and create a DVD. The command I'm using is this: ffmpeg -loop_input -i image.jpg -qscale 2 -i song.flac -aspect 4:3 -target pal-dvd -acodec pcm_s16le -shortest output.mpg However, the resulting video file doesn't have sound at all (testing it on VLC Player). I don't know if I can't combine "-acodec pcm_s16le" with "-target pal-dvd" to override the later, or if there is something else wrong with the command. If I try without the "-acodec pcm_s16le" parameter the video and audio works, I can even create a DVD ISO with it. However, the audio stays as AC3. I wanted to include with the video the lossless audio, not a compressed one. I suppose the DVD standart allows to have PCM audio in it, am I right?

  • How to detect when video is buffering?

    - by Leon
    Hi guys, my question today deals with Flash AS3 video buffering. (Streaming or Progressive) I want to be able to detect when the video is being buffered, so I can display some sort of animation letting the user know to wait just a little longer. Currently my video will start up, hold on frame 1 for 3-4 secs then play. Kinda giving the impression that the video is paused or broken :( Update Thanks to iandisme I believe I'm faced in the right direction now. NetStatusEvent from livedocs. It seems to me that the key status to be working in is "NetStream.Buffer.Empty" so I added some code in there to see if this would trigger my animation or a trace statement. No luck yet, however when the Buffer is full it will trigger my code :/ Maybe my video is always somewhere between Buffer.Empty and Buffer.Full that's why it won't trigger any code when I test case for Buffer.Empty? Current Code public function netStatusHandler(event:NetStatusEvent):void { // handles net status events switch (event.info.code) { case "NetStream.Buffer.Empty": trace("¤¤¤ Buffering!"); //<- never traces addChild(bufferLoop); //<- doesn't execute break; case "NetStream.Buffer.Full": trace("¤¤¤ FULL!"); //<- trace works here removeChild(bufferLoop); //<- so does any other code break; case "NetStream.Buffer.Flush": trace("¤¤¤ FLUSH!"); //Not sure if this is important break } }

  • iPad Video Playback only delivers audio, not visuals.

    - by Dwaine Bailey
    Hi guys, Recently we've developed an iPhone app for an external company, and everything works fine in the app. There is a section where the app pulls video from the client's server, and streams it into the iPhone's MPMoviePlayerController. This works fine on the iPhone and iPodTouch - both the video and the audio show up just great. The problem, however, is that when the app is run on an iPad (using the iPad's iPhone simulator thingo that it does) only the audio plays, and no video can be seen. Does anybody have any suggestions about what may be causing this? I thought perhaps it was the encoding, but then why would this prevent the video from playing on the iPad, and not the iPhone?

  • Getting true video Height/Width from ASF videos

    - by David
    I am trying to convert an ASF video with FFMPEG using an interface called mediahandler. The issue is, the metadata on the ASF video appears to be corrupt. It states that the video is 640x240, and 4:3 aspect ratio. The aspect ratio is correct, but obviously the resolution is not. This causes the converter to incorrectly scale the video, because it uses the resolution to determine the original aspect ratio. I am able to get the aspect ratio metadata, but I'm not sure this solves the issue, because I would think that if the resolution could be incorrect, then so could the aspect ratio metadata. So, is there any way to get the actual height/width? It appears that players like VLC have no issue with this. How do I do such a thing w/ FFMPEG?

  • Broadcast live video from web-cam via plug-in

    - by Freebrainz
    Hello guys! Could you please suggest me what kind of software should I use to broadcast live video from webcam? Web-cam is connected via USB to my server. I want to broadcast video from my webcam on my web-page (HTML, ASP.NET - doesn't matter). I don't want to develop video broadcasting from the beginning - it takes a lot of time to implement good system. I'm looking for ready-to-use plug-in/widget for my site. I found ustream.tv, but live video start playing with delay about 2 seconds... You know, it's not real-time. I need something like Skype/icq/ooVoo... plug-in/widget for my web-site. Are these plug-ins exists in internet? P.S. I know that VideoLAN has ActiveX control. Does VLC provide me with real-time video broadcasting from webcam without any delays like Skype? Thank you!

  • html5 video player with simplest controls (only play and paus)

    - by mathiregister
    hi guys, somehow there are really little tutorials out there for html5 video and audio playback. I simply want to embed video and audio files with customized controls. However the controls should be farely simple. I only need a play-button. If clicked, play gets replaced by pause. that's all! however i even don't know how to embed/display a video without "preload controls". Somehow if i only set (without preload controls) Firefox even don't shows anything. Chrome does show a black window. I would love to be able to use jquery to control the video play and pause button. Maybe you have some little start-approach for me! thank you very much!

  • VB.NET - cannot get Video Preview to work

    - by Yiu Korochko
    Hi, Overflow. I have an application which is supposed to convert a video via DirectShowSource. I have a checkbox which enables a button called "btnviewcrop" which shows a new form called crp.vb for cropping/shearing pixels off the video. Now, I have a Panel1 that I want to set as the owner (the video drawing surface) but when I set it to open, the application crashes (Error: Object reference not set to an instance of an object.) and I do not understand how to fix it. Here is my button code: Imports Microsoft.DirectX.AudioVideoPlayback Private Sub btnviewcrop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnviewcrop.Click Me.ShowInTaskbar = False Me.Enabled = False crp.Show() Dim cropperv As Video cropperv.Owner = crp.preview cropperv.FromFile(labinputfile.Text, True) cropperv.Play() End Sub
