Collaboration diagram for HwVideoDecoder:
Public Member Functions | |
| HwVideoDecoder (AVCodecID av_codec_id, AVHWDeviceType hwtype, int n_threads=1) | |
| Default constructor. | |
| virtual | ~HwVideoDecoder () |
| Default destructor. | |
| virtual Frame * | output () |
| Return a reference to the internal storage of the decoder where the decoded frame is. | |
| virtual bool | pull () |
| Decode in_frame to out_frame. Return true if decoder returned a new frame (into out_frame), otherwise false. Implementation depends on the decoder library. | |
 Public Member Functions inherited from AVHwDecoder | |
| AVHwDecoder (AVCodecID av_codec_id, AVHWDeviceType hwtype, int n_threads=1) | |
| Default constructor. More... | |
| virtual | ~AVHwDecoder () |
| Default destructor. | |
| virtual void | flush () |
| Reset decoder state. How to flush depends on the decoder library. | |
| virtual bool | isOk () |
| The thread that uses this decoder can check if it has gone sour. | |
| Public Member Functions inherited from Decoder | |
| Decoder () | |
| Default constructor. | |
| virtual | ~Decoder () |
| Default destructor. | |
| void | input (Frame *f) |
| Create a copy of the frame into the internal storage of the decoder (i.e. to Decoder::in_frame) | |
| long int | getMsTimestamp () |
| virtual void | releaseOutput () |
| Decoder might want to know that it's ok to overwrite the frame. | |
