vod_segment_count_policy
The `vod_segment_count_policy` directive controls the segment count policy for video on demand (VOD) packaging in NGINX.
Description
The vod_segment_count_policy directive is a part of the NGINX-based VOD module, which is designed for on-the-fly repackaging of video files into different streaming formats (DASH, HLS, etc.). This directive allows you to specify the policy that governs how segments are counted during the packaging process. The segment count can influence aspects such as buffering and playback experience, depending on how the video content is delivered to clients.
There are several policies that can be set with this directive, providing the flexibility to adapt to varying network conditions and playback scenarios. For example, a strict policy may limit the number of segments to ensure that the playback does not exceed a certain threshold, while a more lenient one may allow for more segments, facilitating adaptive streaming. By configuring this directive correctly, administrators can optimize their VOD delivery based on the specific use case or environmental conditions.
The behavior of the vod_segment_count_policy directive is contingent upon the argument provided, which defines the approach to segment counting used by the VOD packager. This is particularly important for applications that serve high-quality video content, as the user experience can be significantly impacted by the number and length of segments generated during streaming.
Config Example
server {
listen 80;
location /videos {
vod_segment_count_policy strict;
# Additional configuration...
}
}Ensure the selected policy aligns with your content delivery requirements; inappropriate settings might degrade playback quality.
Changes to the vod_segment_count_policy may not take effect unless the NGINX service is reloaded. Make sure to test changes in a staging environment.
