The disclosure discloses a video enhancement method and device, and belongs to the field of image processing. The method includes that: each frame in a video is sequentially acquired; and for each current frame, attribute information reflecting a moving state or luminance is determined, a preset mapping relationship is searched to obtain a control parameter corresponding to the attribute information, and video enhancement operation is executed on the current frame by using the control parameter. The device includes: an acquisition module and an enhancement module. By the disclosure, the problem of processing inflexibility caused by execution of the same enhancement over each frame in the video is solved, each frame in the video may be differentially enhanced, frame-based video enhancement is implemented, a video enhancement effect is effectively improved, and quality of the video is improved.

Video enhancement method and device

A video acquisition method and device. The method includes setting a video acquisition class in a programming language framework layer. With the video acquisition class inherits a class in a video acquisition underlying library and registers a callback function for the video acquisition underlying library. The video acquisition class sends a video acquisition command to the video acquisition underlying library and the video acquisition underlying library acquires video data according to the video acquisition command. The callback function is applied to acquire the video data from the video acquisition underlying library and the video data is sent to a coder for video data coding.

Video acquisition method and device

This present disclosure provides a method, system, module, and storage medium for automatic adaptation of hardware encoding and decoding, wherein the method calls a hardware codec of an embedded device to perform encoding and decoding, including the following steps: pre-storing at least one encoding and decoding plugin each of which corresponds to a hardware codec and complies with a pre-defined interface; importing the encoding and decoding plugin and loading the corresponding hardware codec; and encoding or decoding corresponding data. By dynamically loading the plugin, the prevent disclosure solves the problem that the management on different platforms are complex and the compatibilities of different platforms are poor; furthermore, the prevent disclosure improves the encoding and decoding capability of the system and further improves the video quality by reasonably scheduling the hardware codec of the embedded chip.
