Hi I have a streaming video service, basicly, someone pass the H264 video frame by frame to my Decoder element and I need decode and vpp each video frame. I saw the example code it use DecodeHeader fucntion to get the mfxVideoParams and then use it to initialize the mfxVideoDecoder. I try pass first H264 raw frame to DecodeHeader function but it return MFX_ERR_UNDEFINED_BEHAVIOR. Is that single frame is good enought for DecodeHeader function to fill the mfxVideoParam or not ? or DecodeHeader function dont work with streaming video. I can get some configuration data from outside and fill into mfxVideoParams strucutre but that structure looks very complex and I dont what the necessary paramter it needed. here is the struture .
typedef struct _mfxVideoParam {
mfxU32 reserved[3];
mfxU16 reserved3;
mfxU16 AsyncDepth;
union {
mfxInfoMFX mfx;
mfxInfoVPP vpp;
}
mfxU16 Protected;
mfxU16 IOPattern;
mfxExtBuffer **ExtParam;
mfxU16 NumExtParam;
mfxU16 reserved2;
} mfxVideoParam;
the mfxInfoMFX mfx; looks really complex and I dont know which one is necessary.
