Description






Functions




gst_vaapi_profile ()


GstVaapiProfile
gst_vaapi_profile (VAProfile profile);


Converts a VA profile into the corresponding GstVaapiProfile. If
the profile cannot be represented by GstVaapiProfile, then zero is
returned.




Parameters











profile


a VAProfile

 









Returns


 the GstVaapiProfile describing the profile













gst_vaapi_profile_from_caps ()


GstVaapiProfile
gst_vaapi_profile_from_caps (const GstCaps *caps);


Converts caps
 into the corresponding GstVaapiProfile. If the
profile cannot be represented by GstVaapiProfile, then zero is
returned.




Parameters











caps


a GstCaps

 









Returns


 the GstVaapiProfile describing the caps













gst_vaapi_profile_get_va_profile ()


VAProfile
gst_vaapi_profile_get_va_profile (GstVaapiProfile profile);


Converts a GstVaapiProfile into the corresponding VA profile. If
no matching VA profile was found, -1 is returned and this error
must be reported to be fixed.




Parameters











profile


a GstVaapiProfile

 









Returns


 the VA profile, or -1 if none was found












gst_vaapi_profile_get_caps ()


GstCaps *
gst_vaapi_profile_get_caps (GstVaapiProfile profile);


Converts a GstVaapiProfile into the corresponding GstCaps. If no
matching caps were found, NULL is returned.




Parameters











profile


a GstVaapiProfile

 









Returns


 the newly allocated GstCaps, or NULL if none was found












gst_vaapi_profile_get_codec ()


GstVaapiCodec
gst_vaapi_profile_get_codec (GstVaapiProfile profile);


Extracts the GstVaapiCodec from profile
.




Parameters











profile


a GstVaapiProfile

 









Returns


 the GstVaapiCodec from profile













gst_vaapi_entrypoint ()


GstVaapiEntrypoint
gst_vaapi_entrypoint (VAEntrypoint entrypoint);


Converts a VA entry-point into the corresponding GstVaapiEntrypoint.
If the entry-point cannot be represented by GstVaapiEntrypoint,
then zero is returned.




Parameters











entrypoint


a VAEntrypoint

 









Returns


 the GstVaapiEntrypoint describing the entrypoint













gst_vaapi_entrypoint_get_va_entrypoint ()


VAEntrypoint
gst_vaapi_entrypoint_get_va_entrypoint
                               (GstVaapiEntrypoint entrypoint);


Converts a GstVaapiEntrypoint into the corresponding VA
entry-point. If no matching VA entry-point was found, -1 is
returned and this error must be reported to be fixed.




Parameters











entrypoint


a GstVaapiEntrypoint

 









Returns


 the VA entry-point, or -1 if none was found
