Embodiment Construction
[0046] A video encoding / decoding method and device, and a video playing method and device provided in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0047] Such as figure 2 As shown, a video coding method provided by the embodiment of the present invention, in the process of implementing the embodiment of the present invention, the method includes:
[0048] 201: The encoder performs inter-frame encoding of the source image into a P frame;
[0049] 202: Perform intra-frame encoding on the source image to obtain an I frame corresponding to a P frame;
[0050] 203: Store the I frame corresponding to the P frame in the cache of the encoder.
[0051] Wherein, in this embodiment, the step 202 can have three different encoding methods respectively:
[0052] The first encoding method for synthesizing I frames is:
[0053] Obtain the original image of the reference frame of the current P frame;
[0054] The ...
