[0059] First create an AVURLAsset, an implementation of loading video data is as follows:
[0060] AVURLAsset*asset=
[0061] [[AVURLAsset alloc]]initWithURL:videoPath options:nil]
[0062] The parameter videoPath represents the address of the video.
[0063] Then use AVURLAsset to create an AVAssetImageGenerator to capture the image. One implementation is as follows:
[0064] AVAssetImageGenerator*gen=

The invention discloses a video-based sequence frame animation transmission method, a video-based sequence frame animation transmission system and electronic equipment. The transmission method comprises the following steps: receiving a request of downloading a sequence frame animation file by a request end; Obtaining video data corresponding to the sequence frame animation file according to the request; And transmitting the video data to a request end. By utilizing the transmission method, the transmission system and the electronic equipment provided by the invention, the network transmissionefficiency and the transmission quality can be obviously improved.
Description
technical field [0001] The invention relates to a sequence frame animation transmission technology, in particular to a video-based sequence frame animation transmission method, system and electronic equipment. Background technique [0002] Sequence frame images are often used by mobile terminals to make some page effects because they can intuitively display rich content. Sequence frame image is an image sequence composed of several images arranged in order; sequence frame animation refers to the technology of playing sequence frame images one by one according to sequence frame sequence. Sequence frame animation files usually contain multiple images. If these sequence frame animations are transmitted directly, the amount of data to be transmitted is very large. Due to the large amount of transmitted data, it is easy to make transmission errors. Therefore, the sequence frame animation files are usually compressed. After this file compression method is compressed, the amount o...
