How to play a video file in vb.net ?
I need the video to automatically start playing on form load.
Using google will show many results. Here is one that seemed pretty easy to follow:

I am using RNCamera to record video along with react-native-video-helper library for trimming/compressing video. I want to record or transform recorded video like instagram to wide angle(not potrait mode). It's been almost a week I am looking for a solution but I could'nt find anything useful till yet. I have tried react-native-video-processing library as well.
I have figured it out myself, posting answer to any one else struggling with the same scenario:
Go for ffmpeg, you can do almost every thing with this awesome tool, croping, merging, adding emoji's, text to video, triming, removing audio from video and so on.
You can find test application for a quick startup along with the package as well
I am making a game, so at one point I need to play two sounds at once, so I played the first one using the "My.Computer.Audio.Play()" Method to load from resources.
As for the second, I used Windows Media Player to load the second sound In A SPECIFIC FOLDER, now I know it is possible to extract files to a folder and program it to play from there to avoid trouble, but I don't want them to be extracted.
So I'm trying to get the file path from resources and put it in WMP's URL, but couldn't get any result after searching the internet.
Am I missing something?
And if you know any better alternative, make sure it can:
1- Replay sound (coding with timer is ok),
2- Change Sound Position
You can use the MediaPlayer class in code or MediaElement in XAML for playing audio files in a WPF application. Check out the article WPF Media Player In VB.NET for code samples.
So I have a youtube page open where I can watch a video.
But this video was taken down by the user. My open page still has the video, if you go to it again (refresh) the new page does not.
Since I have the video loaded in my browser tab (chrome), how can I go about finding the actual file and saving it?
In the old days of YouTube, it may have been possible to find the single video file on your harddrive and save it, but this is no longer the case. As explained in this Computerphile video, all YouTube videos are now split into tiny pieces and downloaded piece by piece.
You can observe this for yourself if you open up Chrome (or Firefox's) Dev Tools and watch the nnetwork tab. You'll see:
all of the pieces of the video loading bit by bit.
One additional thing you'll learn from the Network tab is that the videos are downloaded as octet streams, so you won't be able to find the links to the pieces hidden in the DOM.
One thing you migth try is, in the Network tab, clear the results and then move the cursor to the beginning of the video. You should see the streams come up again. Right click on the path name and then do a "save as", and save it as 0000.mp4 (or whatever), for all the pieces. You should be able to reassemble these pieces in any video editing software. I tested this by getting two pieces from a random YouTube video.
I couldn't find anything that doesn't require a restart (and hence reload) of Chrome.
One (kludgy) hack if possible, though, would be to run a screen video capture and play the video.
I have done this long back using IE6, i.e. fetch the file from the temporary files location and rename it to the extension flv.
The following links should point you in the right direction, but can't say it will work for sure, as I believe recent chrome versions seem to have a defensive cache implementation.

You might need to tweak the above for your use.
Run a screen recording/capture program such as:
Screenr
CamStudio
Then edit out the youtube bar if its visible.
The buffered video is cached at the following location:
C:\Users\<user name>\AppData\Local\Temp\flaxxxx.tmp
Note you have to change to whatever user you are using, and xxxx is a random number. Also, the .tmp file might be hidden, so make sure your windows explorer is displaying the hidden files.
While the tab is open, you won't be able to copy the file, but if you close it, the file will be automatically deleted. For doing so, download HoboCopy, extract it and after that, run cmd as administrator. Change the directory on the console to the directory where you have extracted HoboCopy and type the following command:
hobocopy C:\users\<user name>\Appdata\Local\Temp C:\videos fla1234.tmp
<user name> - replace with your windows username
C:\videos - the directory where you want the video to be copied to
fla1234.tmp - the name of the file to be copied.
Wait for the copy to be done and then you can rename the destination file, changing '.tmp' to '.flv'. This file can be played with any FLV supporting media player.
i find this software to get the video from temp files folder and play it http://www.nirsoft.net/utils/video_cache_view.html
Video file is cached, therefore suggested ways can help you to save the file. But if you deal with same problems I offer using IDM(Internet Download Manager). After installation of this application for every online video stream (e.g. all flv files in youtube) IDM brings a small picture that you can click on it and downloading will be started automatically without need of any configuration.
You have to install a browser extension to download YouTube videos. You won't find a simple URL for an mp4 file in the HTML source. Try googling "youtube downloader" + your browser name.
As far as I recall, YouTube videos are not served as a continuous HTTP resource, but instead divided into small chunks and assembled client-side by the Flash player. This is why you can jump into the middle of a video, without having to buffer the first half of the video.
Generally speaking, YouTube don't want you to rip their content, so they aren't exactly making it easy for downloaders.
I have few links to .mp4 video files like
file1.mp4
file2.mp4
file3.mp4
I need to play them all in player as one file. Actually not necessarily "as one" file, the player must act like it's one file. My best guess is to create custom controls and playback area for MPMoviePlayerController and divide the playback by time slices.
For instance
file1.mp4 file2.mp4 file3.mp4
-----------|------------|------------
Is this a good approach? Can this be done anyhow easier?
Also, the server, from which I'll get the videos is not customizable and I can't convert videos to MPEG-2 and stream them via .m3u8 files.
Thanks in advance
I guess you can use AVQueuePlayer. It supports multi-item playback. Haven't tried that myself (I used AVPlayer for single-item playback). I believe that AVQueuePlayer usage should reduce your overall efforts. ( You will still be responsible for drawing playback controls )
I sticked up to the scenario I described in the question and was able to create the player component.
I have uploaded a couple of tutorial videos in youtube.
In my winforms application (by using the AxShockwaveFlash object) i reproduce the selected video by the user.
AxShockwaveFlash1.LoadMovie(http://www.youtube ..video1)
Here comes the story.
The first time the user selects a video, reproduction works like a charm.
When the user selects to see the second video
AxShockwaveFlash1.LoadMovie(http://www.youtube ..video2)
the ShockwaveFlash continues the reproduction of the first selection
Try to use
AxShockwaveFlash1.Stop();
AxShockwaveFlash1.Movie = "Your source";
AxShockwaveFlash1.Play();
Pattern to avoid leaving flash arguments behind.
Without knowing how you have integrated the video in your form, the method I would do is using a webBrowsercontrol in the form and embed the video in the control.
msdn on webBrowsercontrol
I had encountered this problem and resolved it by changing the Embed property of the Ax object control to False.
I embed the videos via the movie URL each time as follows:
http://www.youtube.com/v/targetmovie&feature=player_embedded
Works a treat
Tamir,
the video is embedded. Not stored locally
This is because your application is loading flash player loader from the cache and then it's loading the real player from the site , finally this yield a security exception.
In internet explorer , in internet options set to check for new versions of the documents each time you visit the page.
You first need to extract the FLV file like here:
