const vlc_chroma_description_t * vlc_fourcc_GetChromaDescription | ( | vlc_fourcc_t | i_fourcc | ) |

vlc_fourcc_t vlc_fourcc_GetCodec | ( | int | i_cat, |
vlc_fourcc_t | i_fourcc | ||
) |
It returns the codec associated to a fourcc within an ES category.
If not found, it will return the given fourcc. If found, it will always be one of the VLC_CODEC_ defined above.
You may use UNKNOWN_ES for the ES category if you don't have the information.

vlc_fourcc_t vlc_fourcc_GetCodecAudio | ( | vlc_fourcc_t | i_fourcc, |
int | i_bits | ||
) |
It converts the given fourcc to an audio codec when possible.
The fourccs converted are aflt, araw/pcm , twos, sowt. When an incompatible i_bits is detected, 0 is returned. The other fourccs go through vlc_fourcc_GetCodec and i_bits is not checked.

vlc_fourcc_t vlc_fourcc_GetCodecFromString | ( | int | i_cat, |
const char * | psz_fourcc | ||

It returns the codec associated to a fourcc stored in a zero terminated string.
If the string is NULL or has more than 4 characters or doesn't correspond to a string associated with a VLC_CODEC_, it will return 0, otherwise it will one of the VLC_CODEC_ defined above.
You may use UNKNOWN_ES for the ES category if you don't have the information.

const vlc_fourcc_t * vlc_fourcc_GetFallback | ( | vlc_fourcc_t | i_fourcc | ) |
It returns a list (terminated with the value 0) of fourccs in decreasing priority order for the given chroma.
It will return either YUV or RGB fallbacks depending on whether or not the fourcc given is YUV.
It will always return a non NULL pointer that must not be freed.
