avgetsamplefmtnamefmt

avgetsamplefmtnamefmt is a function within the FFmpeg multimedia framework. Its primary purpose is to translate a sample format enum value into its corresponding string representation. Sample formats in FFmpeg define the data type and layout of audio samples, such as integer or floating-point formats, and their bit depth.

The function takes a single argument, which is the sample format enum itself (e.g., AV_SAMPLE_FMT_S16 for signed 16-bit integers). It then returns a constant string that human-readablely identifies this format. For example, passing AV_SAMPLE_FMT_S16 to avgetsamplefmtnamefmt would return the string "s16". Similarly, AV_SAMPLE_FMT_FLT would return "flt".

This function is particularly useful for debugging, logging, or user interface elements where displaying the numerical enum value would be less informative than its textual equivalent. It helps in understanding the audio stream's characteristics without needing to consult FFmpeg's internal documentation or headers directly. The output of avgetsamplefmtnamefmt is typically used in conjunction with other FFmpeg functions for inspecting and manipulating audio data.
