[HELP] H264 video camera trying to change HelloVideoCamera

I am very new to recording video and video encoding of the animals.

In this line, I have error 22

camera_error_t error = camera_start_encode(mCameraHandle, NULL, NULL, NULL, NULL, NULL);

fprintf(stderr, "camera_start_encode() error %d", error); // It returns 22

I checked here https://developer.blackberry.com/native/reference/core/com.qnx.doc.camera.lib_ref/topic/camera_error... what is the error 22, but I do not see the error with 22 values

Here's my complete code

Any help is appreciated. Please, I beg you. Thank you.

Thank you... I eliminated the camera_start_encode function

my main problem was I really need to encode H264 video recording... and now I have the solution... Knobtviker taugtht me... I used the BestCam sample...

added to this camera_init_video_encoder(); to the constructor

and added this line after the opening of the camera

camera_set_videoencoder_parameter (mHandle, CAMERA_H264AVC_BITRATE, 1000000, CAMERA_H264AVC_KEYFRAMEINTERVAL, 3, CAMERA_H264AVC_RATECONTROL, CAMERA_H264AVC_RATECONTROL_VBR, CAMERA_H264AVC_PROFILE, CAMERA_H264AVC_PROFILE_HIGH, CAMERA_H264AVC_LEVEL, CAMERA_H264AVC_LEVEL_4);

These properties too

QByteArray groupBA is mFwc-> windowGroup () .toLocal8Bit ();.
QByteArray winBA is mFwc-> windowId () .toLocal8Bit ();.
ERR = camera_set_videovf_property (mHandle, CAMERA_IMGPROP_HWOVERLAY, 1, CAMERA_IMGPROP_FORMAT, CAMERA_FRAMETYPE_NV12, CAMERA_IMGPROP_WIN_GROUPID, groupBA.data (), CAMERA_IMGPROP_WIN_ID, winBA.data (), CAMERA_IMGPROP_WIDTH, CAMERA_IMGPROP_HEIGHT, 720, 720, CAMERA_IMGPROP_MAXFOV, 0);
ERR = camera_set_video_property (mHandle, CAMERA_IMGPROP_WIDTH, CAMERA_IMGPROP_HEIGHT, 720, 720, CAMERA_IMGPROP_AUDIOCODEC, CAMERA_AUDIOCODEC_AAC, CAMERA_IMGPROP_STABILIZATION, 1); CAMERA_IMGPROP_VIDEOCODEC, CAMERA_VIDEOCODEC_AVC1,

now I can record video in H264 format.

Glitches video while trying to change

I really need help. I'm a little frustrated. I just bought a JVC Everio HDD Camcorder. I do a video montage of a theatre in the region. I tried to download the video directly from the camcorder multiple times in the first 4 Elements. I tried to save media in a file and upload it in the file. I also tried to download on the multimedia software supplied with the camcorder. Whenever I tried (which is several times) I sometimes right wing media that there is an error, so I try again. Or when I put in the time line and start editing, there are seeds of green screen. But when I look on the software with the camera it plays perfectly fine in the place of one. It's the same with when I play it in Windows Movie Maker. I like to use the primary cause I can add a Menu screen and edit the video better. I don't want to have on any hidden through Movie Maker first. Anyone know why or how to fix the glitches? It seems to be on every clip I have. The video plays as well on my friends computer. I tried to close the first and reopen it. I tried a new project. I intend to do more video editing with this unit in the future so I don't want to be like that not all projects. Any advice or words of wisdom would be greatly appreciated. Thank you
I noticed the other post, but some of it was in Dutch. But it's the same problem and I believe that the same camera that I use. I did not yet get point transitions cause, I immediately noticed the green. My magnification is fit. The videos are also is a mod my first is 4.0, however. I save a clip Window Movie Maker and registered as a .wmv and seems to work very well. I wouldn't really have to do all my editing in Movie Maker, but...
Thank you

This is a mod files are bad general new when it comes to Premiere Elements.

I know from your original post that you want to avoid to convert the format of your video to a more appropriate for Premiere Elements whose native format of the timeline is DV AVI.

Then, how about this:

1 as a mini project, change is a mod in .mpg file name and see if you have better luck getting video in Premiere Elements and editing it there.

2. If that does not succeed, then try the conversion of MPEG Streamclip (is a mod in DV AVI) and see if that spell success (which it usually does).

3. then decide what path will follow you for big project once these minis (experiences) tests.

There's a FAQ here on conversion to DV AVI and MPEG Streamclip. If you can't find it, I post in the morning for you. I used the program and have found fast, easy and effective. If necessary, I can give you a step by step I used several times with success.

You may have installed one or more variants of the malware "VSearch' ad-injection. Please back up all data, and then take the steps below to disable it.

Do not use any type of product, "anti-virus" or "anti-malware" on a Mac. It is never necessary for her, and relying on it for protection makes you more vulnerable to attacks, not less.

Malware is constantly evolving to work around defenses against it. This procedure works now, I know. It will not work in the future. Anyone finding this comment a couple of days or more after it was published should look for a more recent discussion, or start a new one.

Step 1

VSearch malware tries to hide by varying names of the files it installs. It regenerates itself also if you try to remove it when it is run. To remove it, you must first start in safe mode temporarily disable the malware.

Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for other instructions.

Step 2

When running in safe mode, load the web page and then triple - click on the line below to select. Copy the text to the Clipboard by pressing Control-C key combination:
```
/Library/LaunchDaemons
```
In the Finder, select

Go ▹ go to the folder...

from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

A folder named "LaunchDaemons" can open. If this is the case, press the combination of keys command-2 to select the display of the list, if it is not already selected.

There should be a column in the update Finder window. Click this title two times to sort the content by date with the most recent at the top. Please don't skip this step. Files that belong to an instance of VSearch will have the same date of change for a few minutes, then they will be grouped together when you sort the folder this way, which makes them easy to identify.

Step 3

In the LaunchDaemons folder, there may be one or more files with the name of this form:

com Apple.something.plist

When something is a random string, without the letters, different in each case.

Note that the name consists of four words separated by dots. Typical examples are:

com Apple.builins.plist

com Apple.cereng.plist

com Apple.nysgar.plist

There may be one or more items with a name of the form:

com.something.plist

Yet once something is a random string, without meaning - not necessarily the same as that which appears in one of the other file names.

These names consist of three words separated by dots. Typical examples are:

com.semifasciaUpd.plist

com.ubuiling.plist

Sometimes there are items (usually not more than one) with the name of this form:

com.something .net - preferences.plist

This name consists of four words (the third hyphen) separated by periods. Typical example:

com.jangly .net - preferences.plist

Drag all items in the basket. You may be prompted for administrator login password.

Restart the computer and empty the trash.

Examples of legitimate files located in the same folder:

com.apple.FinalCutServer.fcsvr_ldsd.plist

com Apple.Installer.osmessagetracing.plist

com Apple.Qmaster.qmasterd.plist

com Apple.aelwriter.plist

com Apple.SERVERD.plist

com Tether.plist

The first three are clearly not VSearch files because the names do not match the above models. The last three are not easy to distinguish by the name alone, but the modification date will be earlier than the date at which VSearch has been installed, perhaps several years. None of these files will be present in most installations of Mac OS X.

Do not delete the folder 'LaunchDaemons' or anything else inside, unless you know you have another type of unwanted software and more VSearch. The file is a normal part of Mac OS X. The "demon" refers to a program that starts automatically. This is not inherently bad, but the mechanism is sometimes exploited by hackers for malicious software.

If you are not sure whether a file is part of the malware, order the contents of the folder by date modified I wrote in step 2, no name. Malicious files will be grouped together. There could be more than one such group, if you attacked more than once. A file dated far in the past is not part of the malware. A folder in date dated Middle an obviously malicious cluster is almost certainly too malicious.

If the files come back after you remove the, they are replaced by others with similar names, then either you didn't start in safe mode or you do not have all the. Return to step 1 and try again.

Step 4

Reset the home page in each of your browsers, if it has been modified. In Safari, first load the desired home page, then select

▹ Safari preferences... ▹ General

and click on

Set on the current Page

If you use Firefox or Chrome web browser, remove the extensions or add-ons that you don't know that you need. When in doubt, remove all of them.

The malware is now permanently inactivated, as long as you reinstall it never. A few small files will be left behind, but they have no effect, and trying to find all them is more trouble that it's worth.

Step 5

The malware lets the web proxy discovery in the network settings. If you know that the setting was already enabled for a reason, skip this step. Otherwise, you should undo the change.

Open the network pane in system preferences. If there is a padlock icon in the lower left corner of the window, click it and authenticate to unlock the settings. Click the Advanced button, and then select Proxies in the sheet that drops down. Uncheck that Auto Discovery Proxy if it is checked. Click OK, and then apply.

Step 6

This step is optional. Open the users and groups in the system preferences and click on the lock icon to unlock the settings. In the list of users, there may be some with random names that have been added by the malware. You can remove these users. If you are not sure whether a user is legitimate, do not delete it.

I have 3 short videos I tried emailing stuck in Outbox of my iPhone 6. They tried to send more than an hour. I can't delete them, "Change" is not available in the Outbox. How can I get rid of these so mail will stop trying?

I have 3 short videos I tried emailing stuck in Outbox of my iPhone 6. They tried to send more than an hour. I can't delete them, "Change" is not available in the Outbox. How can I get rid of these so mail will stop trying?

Can drag you across the message in the Outbox overview to get the Red delete button? It's been a while since I had paste an email in the Outbox, so I don't remember if that's possible.

IF your account is an IMAP account, try to delete the e-mail on the Mac. Actions sync between devices in IMAP email, so they should be in the Outbox on the server and you should be able to get to them in the Mail from Mac application, use you it, or in a web browser on the server.

IF this is not possible for some reason, try the mail application to the phone reboots and the closing force force the phone and then try again. Press the Home button twice quickly. You will see small glimpses of your applications recently used. Blow up the Swipe on application brief mail app to close

To force the reboot your device, press and hold the two buttons of sleep/wake and home for at least ten seconds, until you see the Apple logo.

Hello mpm068,

Thank you for using communities of Apple Support.

Since your iSight webcam works up to the time that your Mac goes to sleep, I would like you to start please help desk trying to replicate this problem then to reboot in safe mode:
1. Choose the Apple menu > shut down.
2. After your Mac stops, wait 10 seconds, then press the power button.
3. As soon as you hear the startup tone, hold down the SHIFT key.
  
  You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.
4. Release the SHIFT key when you see the gray Apple logo and progress indicator.
To exit safe mode, restart your Mac, but no press during the startup.
OS X El Capitan: start in safe mode

Take care.

Hi Bob,

Welcome to the Microsoft community.

I understand how it could be frustrating when things do not work as expected. Please, I beg you, don't worry I'll try my best to resolve the issue.

1. don't you make changes to the computer before the show?
2. what operating system is installed on the computer?

I suggest you run fixit material and devices and see if that helps.

SDRAM error a video camera and pray portable computer

Hello

I have a 16 GB sandisk Extreme. I've been working successfully in my video camera.

After 20% shooting, camera reports errors and the card cannot be read.

When I put the card in my laptop it prompts "format?

I think that the card has become corrupted.

Q1: can I get data / videos of this map-if yes how. I tried to scan with Rescue Pro deluxe, and it doesn't seem to be able to read anything. This is the best software for recovery?

Q2: If I format the sdram memory, it will totally wipe the card and then I won't be able to recover the data, or I'll be able to analyze with pro deluxe grab the videos?

Thank you

Ian

Problem solved.

So here's how I solved this and some suggestions for Sandisk / panasonic.

So the scenarios is as follows, the video recorder not turn off on a few occasions where she was placed in the bag and registered 2 massive records. My thought is that it corrupted the disk header.

Whenever it was designed SDram video camera, the camera flashed an error with the card. When I put it in a Windows system, I asked a disc format.

So on advice form one of the techs at work, I used Linux, linux.

I created a USB bootable from this site web http://www.sysresccd.org/SystemRescueCd_Homepage

Then started from the USB on a relativley new portable (i.e. more recent SD card probbaly)

Once the linux system has started and I put the card in the card reader for laptop, linux was able to read the disk is full.

Why linux reads the formats of microsoft disk I can't explain better than microsoft.

I would say that Sandisk create a Test case to see what happens when sandisk extreme tent complete whole disk and especially using a Panasonic VCR.

I hope this helps others.

all the best

Ian

PS - Sandisk RescuePro CD (not free) I downloaded these tools and could not get the application to read the disc.

There are several versions and was kindly pointed out by LC technologies various utilities.

IM always shocked at how linux was able to read the disc without problem.

The external drive such as a computer identification message mystifies me. External hard drive is not a computer, it's the disk in question.
When I tried as admin TAKEOWN and ICACLS I got access denied.
I tried unlocker and move at the start without success. Can what steps I take to get to these files?

Win Vista Ultimate 64-bit SP2

Hello

After several months of unsuccessful attempts to clean up the files of 'wrong' on my external share disk, files and folders prior, that I could not change or remove. I finally had success.
My stepson who is a computer expert came to visit and this solution to condition:
He defined a user administrator in Windows exactly equal to the owner of the files on the external drive that I couldn't.
He did this owner - admin - part of the WORKING group using the Western Digital user interface.
With this ID, it copied the files with the wrong files in a temporary folder, deleted the wrong file and renamed the temp folder to the original folder name. That corrects bad owners and provided write access where I had only read previously accesss.
He had no idea about how the property has been corrupted by ROBOCOPY, but I am very happy with its solution.
I have this post in the hopes that it may help others.
