DirectShow filter to delay uncompressed video or audio streams in buffering or waiting modes.
Overview
Delayer is DirectShow filter to delay uncompressed video or uncompressed audio (PCM, float) streams. 2 modes of operation are supported: buffering samples in memory and delaying input samples. The input and output allocators can be selected for optimal performance.
Features
Buffering mode.<\b> The delay is implemented by storing delayed data from samples in the internal buffers. Additional memory buffers are allocated for this. This mode can be used for any type of source - live and file.
- The delay is implemented by holding the received samples until the required delay is reached (input is closed for the duration of the delay). Additional memory for storing delayed data from samples is not used, only regular buffers from allocators are used. This mode can only be used for file sources without stream sync by timer/Reference Clock. Using it for live sources (synchronized by timer/RC) will result in unpredictable frame/sample loss.
- Lots of fixes for problematic mp4 files.
Specifications and description of user interfaces can be found in the .idl file in the \Idl folder of the filter installation directory.
