int av_vdpau_get_profile ( AVCodecContext * avctx,

VdpDecoderProfile * profile

)

Get a decoder profile that should be used for initializing a VDPAU decoder.

Should be called from the AVCodecContext.get_format() callback.

Parameters: avctx the codec context being used for decoding the stream

profile a pointer into which the result will be written on success. The contents of profile are undefined if this function returns an error.

Returns: 0 on success (non-negative), a negative AVERROR on failure.
