Struct AVSampleFormat

#[repr(transparent)]
pub struct AVSampleFormat(pub i32);

Audio sample formats used in FFmpeg’s AVSampleFormat enumeration.

The sample format defines how audio samples are stored in memory, including:

• Bit depth (8-bit, 16-bit, 32-bit, 64-bit)
• Signed vs Unsigned (U8 is unsigned, others are signed)
• Floating-point vs Integer
• Packed vs Planar (Planar formats store each channel separately)

See the official FFmpeg documentation: https://ffmpeg.org/doxygen/trunk/samplefmt_8h.html
