int ff_isom_write_vpcc ( AVFormatContext s,
AVIOContext pb,
AVCodecParameters par 
)

Writes VP codec configuration to the provided AVIOContext.

Parameters
saddress of the AVFormatContext for the logging context.
pbaddress of the AVIOContext where the vpcC shall be written.
paraddress of the AVCodecParameters which contains codec information.
Returns
>=0 in case of success, a negative value corresponding to an AVERROR code in case of failure
