Using external codecs - using x264.

Using an external codec - Using x264

oCam supports external codecs (VFW), and here we will learn how to use the x264 codec.
 

You can download the x264 codec from the site below.

http://sourceforge.net/projects/x264vfw/


Go to the site and click the download button.


 

Download starts automatically.

For the installation screen, you can just click Next.

Agree to the license agreement.

Specify the installation path.

Installation is complete.

Click Finish.


After installing the codec, you must restart oCam to see it in the external codec list.

After restarting oCam, click the Codec button on the main oCam window and click the External Codec menu.


 

Check the Use External Codec box.



In the list, select x264vfw - H264/MPEG-4 AVC codec.



Then click the Settings button to view detailed codec settings.



A codec settings window opens as shown below. Since this is not normal video encoding but real-time screen recording, select Ultrafast in Preset and check the Zero Latency box to make encoding as fast as possible, then click OK.

(This setting is useful for real-time recording, and you can adjust it as appropriate for your situation.)

After setting it this way and starting recording, it will be recorded using the x264 codec.




If you record like this, the recording is done using x264 codec.


* For game recording, if the game you want to record is 64-bit, you must also install the 64-bit version of x264vfw (by default, unless you touch the option during x264vfw installation), x264vfw-Configure x264vfw64 from the Start menu. Run it and set it up as described above.


* Keep / Accept only YUV 4: 2: 0, Keep / Accept only YUV 4: 2: 2, Keep / Accept only YUV 4: 4: 4 are not supported for x264vfw setting and recording will fail when using this setting.

How to Fix the Issue of 7 Days to Die Not Being Detected for Game Recording (Anti-Cheat Related)

When recording a game with oCam, problems may occur if a game with an AntiCheat feature is running. AntiCheat software may block recording software or cause conflicts, which can prevent oCam from working properly. Below is a detailed explanation of how to solve this problem and record games smoothly with oCam.


To resolve problems caused by the AntiCheat feature, you can launch the game without AntiCheat enabled. You can use an option provided by Steam or run a specific game executable directly to bypass AntiCheat. Below are two methods:


Method 1: Launch the game from Steam without AntiCheat  

1. Launch the Steam client and select the game you want to record (for example, 7 Days to Die) from your Library.  

2. On the game's detail page, click the blue 'Play' button.  

3. When the launch options window appears, select the 'Launch Without AntiCheat' option.  

4. The game will launch without AntiCheat, allowing normal recording with oCam.


Method 2: Run the game executable directly  

For some games, you can disable AntiCheat by running the executable directly from the Steam library folder. For example, in the case of 7 Days to Die:  

1. Go to the Steam library path. The default path is `SteamLibrary\steamapps\common\7 Days To Die\`.  

2. In that folder, find the `7DaysToDie.exe` file and double-click it to run it.  

3. When launched this way, AntiCheat is automatically disabled, and you can record the game in oCam without any issues.


Applying the methods above can resolve conflicts caused by AntiCheat and allow you to record the game smoothly with oCam. However, disabling AntiCheat may cause restrictions in online multiplayer mode, so make sure your recording is intended for offline play or single-player mode. If the problem persists, using the latest game patch or the latest version of oCam may also help.
