Configuring LAV Filters

download codecThis is how to complete the configuring LAV Filters. As you know the LAV Filters are a powerful set of open-source DirectShow filters. This allows you to play a number of audio and video formats. I will show you how to optimise the filters for bst performance and how to get the best settings for the LAV filters.  I am going to focus on settings for audio and video decoding, hardware acceleration, bitstreaming, and subtitle handling.

Configuring LAV Filters

These are the basic configurations for the software.

LAV Initial Setup and Installation

Before diving into configuration, you must install LAV Filters. Here’s a straightforward guide:

1. Download the Installer:

– You will need to download the LAV filter software from this website.
– Likewise you will need to ensure that you have download the version compatible with your operating system (32-bit or 64-bit).

2. Run the Installer:

– Now you will need to execute the downloaded installer file.
– Additionally follow the on-screen instructions. Likewise, choosing what you wish to install. In addition I would recommend that you install all the components. This being the LAV Splitter, LAV Audio, and LAV Video. You can also see the Haali media splitter as well.

3. Complete Installation:

– Once the installation is complete, LAV Filters should be ready to use with your media player. Most players will automatically detect and utilize LAV Filters.

Likewise see the article that I wrote on the compare LAV Filters with FFDShow as well as the Media Player Classic with External LAV Filters as well.


Configuring Video Decoding

Accessing LAV Video Configuration

To begin configuring LAV Filters for video decoding:

1. Open LAV Video Configuration:

– Firstly launch your media player and then play a video file on your computer. (See also the LAV Filter Format Settings)
– Seconfly right-click on the video screen. Then, navigate to the filters menu, and select “LAV Video Decoder.”
– Alternatively, you can open the LAV Video Configuration tool directly from the Start menu or installation folder.


Hardware Acceleration

For those who have a modern GPU there is also hardware acceleration. You will need this for a more efficient video playback. This is mainly with those videos which use high-definition and 4K content. If you do experience errors, then turn of the hardware acceleration. LAV Video supports several hardware acceleration methods:

1. DXVA2 (DirectX Video Acceleration):

– This is most ideal for most modern GPUs.
– Likewise in the LAV Video Configuration window, go to the “Hardware Acceleration” tab.
– Lastly you will need to select “DXVA2 (native)” for best performance. If you encounter compatibility issues, try “DXVA2 (copy-back).”


– You will need to use the NVIDIA GPUs, offering robust performance.
– Lastly you will need to choose “NVIDIA CUVID” if you have an NVIDIA graphics card.

3. Intel Quick Sync:

– Suitable for Intel CPUs with integrated graphics.
– Select “Intel QuickSync” for efficient video decoding on Intel platforms.

4. D3D11:

– Provides a modern alternative to DXVA2, leveraging Direct3D 11.
– Select “D3D11” if you have a compatible GPU and prefer using newer APIs.


Adjusting Other Video Settings

1. Codec Selection:

– In the “Formats” tab, ensure all relevant video formats (e.g., H.264, HEVC) are checked to enable LAV Video to handle these codecs.

2. Deinterlacing:

– Go to the “Deinterlacing” tab.
– Additionally you must then select “Auto” for automatic deinterlacing based on content.
– Likewise you will need to choose “Disabled” if you know your content is progressive, to save processing power.

3. Color Formats:

– In the “Output Formats” tab, select the color formats your display supports. Common options include NV12, YV12, and P010 for 10-bit video.


Configuring Audio Decoding

Accessing LAV Audio Configuration

Similar to video, configuring audio settings requires accessing the LAV Audio Configuration:

1. Open LAV Audio Configuration:

– While playing an audio or video file, you must right-click the screen. Then, navigate to the filters menu, and select “LAV Audio Decoder.”
– You can also open the LAV Audio Configuration tool from the Start menu or installation folder.


LAV Bitstreaming

Bitstreaming allows digital audio to pass through directly to your receiver for decoding, preserving the highest quality:

1. Enable Bitstreaming:

– In the “Bitstreaming” tab, check the boxes for the audio formats your receiver supports (e.g., AC3, DTS, TrueHD, DTS-HD).
– Ensure that your media player is configured to pass through bitstreaming. See Potplayer as well as the Media Player.


Adjusting Other Audio Settings

1. Output Formats:

– In the “Formats” tab, select the audio formats you want LAV Audio to decode internally (e.g., AAC, MP3, FLAC).
– Likewise you will need to deselect formats you prefer to bitstream to your receiver.

2. Mixing:

– In the “Mixing” tab, you can enable mixing if you want LAV Audio to downmix multi-channel audio to stereo or another format.
– Lastly you must select your desired output channels (e.g., Stereo, 5.1).

3. Audio Delay:

– If you experience audio sync issues, use the “Audio Delay” setting to adjust the timing.


Configuring Subtitle Handling

Accessing Subtitle Configuration

Subtitle handling is managed through the media player itself, but LAV Filters play a role in ensuring proper subtitle support:

1. Open Subtitle Configuration:

– In your media player, access the subtitle configuration settings.
– Ensure that the player is set to use LAV Filters for subtitle rendering if applicable.


Subtitle Formats and Settings

1. Subtitle Formats:

– Ensure that common subtitle formats (e.g., SRT, ASS, PGS) are supported by your media player and LAV Filters.

2. Subtitle Sync:

– If subtitles are out of sync, adjust the subtitle delay in your media player.

3. Style and Appearance:

– Customize subtitle appearance (font, size, color) through your media player’s settings for better readability.


Additional Tips for Optimal Performance

Keeping LAV Filters Updated

Regular updates ensure you have the latest improvements and bug fixes:

1. Check for Updates:

– You will need to periodically download the latest version.
– Install updates as they become available to benefit from new features and optimizations.


Player Compatibility

Ensure your media player is compatible with LAV Filters:

1. Recommended Players:

– Use media players known for good integration with LAV Filters, such as Media Player Classic Home Cinema (MPC-HC) or Kodi.

2. Player Settings:

– Configure your media player to use LAV Filters for decoding. This setting is usually found in the player’s codec or filter settings.


System Performance

Optimize your system for the best playback experience:

1. System Resources:

– Ensure your system meets the recommended hardware specifications for smooth playback, especially for high-definition content.

2. Background Processes:

– Close unnecessary background applications to free up system resources for media playback.


Troubleshooting Common LAV Issues

Video Playback Issues

1. Stuttering or Dropped Frames:

– Firstly you must ensure hardware acceleration is properly configured.
– Update your GPU drivers to the latest version.
– Check that your system meets the required specifications for the content you are playing.

2. No Video:

– Verify that LAV Video is selected as the decoder in your media player.
– Check for conflicts with other installed codecs or filters.


Audio Playback Issues

1. No Audio:

– Ensure LAV Audio is selected as the decoder.
– Check that your audio output device is correctly configured in both your system and media player.

2. Audio Sync Problems:

– Adjust the audio delay setting in LAV Audio Configuration.
– Verify that your system’s audio drivers are up to date.


LAV Subtitle Issues

1. Subtitles Not Displaying:

– Ensure that subtitles are enabled in your media player.
– Verify that the subtitle format is supported.

2. Subtitle Sync Problems:

– Adjust the subtitle delay setting in your media player



Configuring LAV Filters for best performance involves a balance of adjusting settings for video as well as the audio decoding. Likewise you can also now enable hardware acceleration as well as setting up bitstreaming for high-definition audio. So by following the steps outlined in this guide, you can enhance your media playback experience, ensuring smooth and high-quality performance across various media formats. Regular updates and ongoing system optimizations further ensure that your setup remains capable of handling new and emerging multimedia technologies.
