Abstract: A video processing method and system and a related device are disclosed, an encoder sends a method for compressing a pixel value of a video image to a decoder, the method includes a mapping between a pixel value of the video image before compression and a pixel value of the video image after the compression; compressing, by the encoder according to the method for compressing a pixel value, the pixel value of the video image to obtain a video image to be encoded; encoding, by the encoder, the video image to be encoded to obtain a video image encoded stream; and sending, by the encoder, the video image encoded stream to the decoder, the decoder receives and decodes the video image encoded stream to obtain a decoded video image, and decompresses a pixel value of the decoded video image to restore the pixel value of the video image before compression.

Abstract: A video conference recording method, device, and system, which can implement recording and playback of a video of a conference according to a user requirement when the video conference is in progress. The method includes receiving a playback request message input by a user; sending the playback request message to a recording server, so that the recording server selects recorded streaming media information according to the playback request message; receiving a combination data stream sent by the recording server, where the combination data stream includes at least one channel of the streaming media information that is selected, and each of the at least one channel of the streaming media information is corresponding to one conference site; and displaying the at least one channel of the streaming media information that is received. The embodiments of the present invention are used to implement recording of a video conference.
