Constant WAVE_RIFF_CHUNK_SIZE

pub const WAVE_RIFF_CHUNK_SIZE: &'static str;
Available on crate feature dep_sdl3 only.
Expand description

A variable controlling how the size of the RIFF chunk affects the loading of a WAVE file.

The size of the RIFF chunk (which includes all the sub-chunks of the WAVE file) is not always reliable. In case the size is wrong, it’s possible to just ignore it and step through the chunks until a fixed limit is reached.

Note that files that have trailing data unrelated to the WAVE file or corrupt files may slow down the loading process without a reliable boundary. By default, SDL stops after 10000 chunks to prevent wasting time. Use WAVE_CHUNK_LIMIT to adjust this value.

The variable can be set to the following values:

  • “force” - Always use the RIFF chunk size as a boundary for the chunk search.
  • “ignorezero” - Like “force”, but a zero size searches up to 4 GiB. (default)
  • “ignore” - Ignore the RIFF chunk size and always search up to 4 GiB.
  • “maximum” - Search for chunks until the end of file. (not recommended)

This hint should be set before calling [SDL_LoadWAV()] or [SDL_LoadWAV_IO()]

§Availability

This hint is available since SDL 3.2.0.
