Function: avcodecFindBestPixFmtOfList()

avcodecFindBestPixFmtOfList(pixFmtList, srcPixFmt): AVPixelFormat

Defined in: src/lib/utilities.ts:1306

Pick the best-matching pixel format from a list for a given source format.

Chooses the format from pixFmtList that converting srcPixFmt to incurs the least loss (color depth, chroma subsampling, alpha). Useful to select a codec-supported target pixel format that preserves as much of the source as possible (e.g. yuv422p over yuv420p when the input is yuv444p).

Direct mapping to avcodec_find_best_pix_fmt_of_list().

Parameters

pixFmtList

AVPixelFormat[]

Candidate pixel formats (e.g. a codec's supported formats)

srcPixFmt

AVPixelFormat

Source pixel format to convert from

Returns

AVPixelFormat

The least-loss pixel format from the list

Example

const target = avcodecFindBestPixFmtOfList(codec.pixelFormats, frame.format);
