Finally if no pixel format has been found, returns AV_PIX_FMT_NONE.

See av_get_chroma_sub_sample() for a function that asserts a valid pixel format instead of returning an error code. Its recommended that you use avcodec_get_chroma_sub_sample unless you do check the return code!

Parameters

int av_get_pix_fmt_loss ( enum AVPixelFormat  dst_pix_fmt,
enum AVPixelFormat  src_pix_fmt,
int  has_alpha 
)

Compute what kind of losses will occur when converting from one specific pixel format to another.

When converting from one pixel format to another, information loss may occur. For example, when converting from RGB24 to GRAY, the color information will be lost. Similarly, other losses occur when converting from some formats to other formats. These losses can involve loss of chroma, but also loss of resolution, loss of color depth, loss due to the color space conversion, loss of the alpha bits or loss due to color quantization. av_get_fix_fmt_loss() informs you about the various types of losses which will occur when converting from one pixel format to another.

Parameters
[in]dst_pix_fmtdestination pixel format
[in]src_pix_fmtsource pixel format
[in]has_alphaWhether the source pixel format alpha channel is used.
Returns
Combination of flags informing you what kind of losses will occur (maximum loss for an invalid dst_pix_fmt).
