AV_FRAME_FLAG_LOSSLESS

#define AV_FRAME_FLAG_LOSSLESS   (1 << 5)

A decoder can use this flag to mark frames which were originally encoded losslessly.

For coding bitstream formats which support both lossless and lossy encoding, it is sometimes possible for a decoder to determine which method was used when the bitstream was encoded.
