What Video Codecs and Container Formats Are Supported?
oCam supports a range of video codecs and container formats so that users can choose from various recording options.
Below is information about the video codecs supported by oCam.
* How to Check Supported Video Codecs
You can check the video codecs supported by oCam simply by clicking the 'Codec' button in the oCam main window. From this menu, you can easily view and adjust the list of available codecs and their settings.
* Supported Video Codecs
oCam supports the following video codecs for different container formats. Each codec is encoded according to the selected container format:
- MPEG-1: Used with the AVI container format and widely compatible as an early digital video compression standard.
- MPEG-2: Used with the TS and VOB container formats and suitable for DVDs and broadcast streaming.
- MPEG-4: Used with a wide range of container formats, including MP4, MKV, M4V, MOV, FLV, and WMV. oCam uses MPEG-4 as its default codec, offering high compression and good quality.
- XVID: Used with the AVI container format. It is an open-source codec based on MPEG-4, and oCam internally uses the MPEG-4 codec with only the FourCC set to XVID.
- OpenDivx: Used with the AVI container format, also based on MPEG-4, with the FourCC set to OpenDivx.
- Microsoft MPEG-4 Part 2: Used with the AVI container format and set as oCam's default codec. It can be played in most video players, such as Windows Media Player, without installing additional codecs.
- Microsoft MPEG-4 Part 3: An additional option available for the AVI container format, offering compatibility and quality.
* Relationship Between Container Formats and Codecs
oCam supports various container formats, and according to the image you provided, the supported container formats are as follows:
- MP4 (MPEG-4 Part 14): Uses the MPEG-4 codec.
- MKV (Matroska): Uses the MPEG-4 codec.
- M4V (iPod MPEG-4): Uses the MPEG-4 codec.
- MOV (QuickTime): Uses the MPEG-4 codec.
- WMV (Windows Media Video): Uses the MPEG-4 codec.
- FLV (Flash Video): Uses the MPEG-4 codec.
- AVI (Audio Video Interleave): Uses MPEG-1, MPEG-2, MPEG-4, XVID, OpenDivx, Microsoft MPEG-4 Part 2, and Part 3.
- TS (MPEG-2 Transport Stream): Uses the MPEG-2 codec.
- VOB (MPEG-2 PS): Uses the MPEG-2 codec.
- GIF (Graphics Interchange Format): Can be saved as an animated GIF when recording video.
- Audio Recording: Saved in AAC (MP4) format.
By default, oCam records in the AVI container using the Microsoft MPEG-4 Part 2 codec, and this setting is suitable for beginners because it can be played immediately in Windows Media Player and other players without installing additional codecs. MPEG-4, XVID, and OpenDivx are all internally based on the MPEG-4 codec, with only different FourCC codes used to extend compatibility.
* Audio Codec
The audio data saved during recording is encoded in MP3 format, and in some cases, such as with the MP4 container, AAC format is also supported.
* Additional Information
If you install external codecs, you can use more codec options, which will be covered in detail in a separate post. You can adjust oCam's codec settings to match your desired quality and file size, so check the options through the 'Codec' button and test them as needed.

What to Do If the "Failed to url_fopen" Error Message Appears and Recording Does Not Start
When creating a recording file in oCam, an error may occur if the file cannot be saved to the save path specified by the user. This issue is usually caused by access permissions for the save path or an incorrect path setting. Below is a detailed explanation of how to change the save path to resolve this problem.
To fix the recording file save error, the most effective method is to change oCam's save path to a different location. Please follow the steps below:
1. In the oCam main window, click 'Tools' in the top menu, then select 'Options'.
2. When the Settings window opens, click the 'Save' category in the left menu.
3. In the 'Save' tab, find the 'Save Path' item, check the currently configured path, and change it to a new location.
4. After making the change, click the 'OK' button to save the settings.
By default, it is recommended to set the save path to the Desktop. The Desktop generally has the access permissions needed for all programs to create files, so save errors are less likely to occur. For example, if you set the Desktop path to `C:\Users\[User Name]\Desktop`, in most cases the recording file will be saved without errors.
After changing the save path, restart oCam and try recording again to check whether the problem has been resolved. If the issue continues, it is also a good idea to check whether the selected folder has write permission and whether there is enough disk space.
