WAVE_RIFF_CHUNK_SIZE

Controls 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 the

environment variable SDL_WAVE_CHUNK_LIMIT to adjust this value.

This 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)
