  • Publication number: 20190222849
    Abstract: A bit rate allocation method is provided for a bit rate allocation device. The method includes obtaining an intra prediction frame (I-frame) of a to-be-encoded video, and obtaining a bit-rate characteristic parameters associated with the I-frame. The bit-rate characteristic parameters include a number of video frames in a group-of-picture (GOP) in which the I-frame is located, a pixel number of the I-frame, and a proportion of an inter prediction macroblock in a historical inter prediction frame (P-frame) before the I-frame. The method also includes determining an allocated bit rate of the I-frame according to each bit-rate characteristic parameter.

  • Publication number: 20190182480
    Abstract: A method and an apparatus for processing a video bitrate, a storage medium, and an electronic device are provided. The method is performed by at least one processor and includes acquiring a number of video frames included in a current group of pictures, a starting frame of the current group of pictures being a current I frame, acquiring a target bitrate of the current I frame, based on the number of the video frames included in the current group of pictures, and encoding the current I frame, based on the target bitrate.

  • Publication number: 20190098339
    Abstract: Video data processing method and apparatus are provided. The method includes: encoding, by an encoder side, obtained original video data according to a hierarchical P-frame prediction HPP structure to obtain an HPP bitstream; redundancy-coding the HPP bitstream according to a forward error correction FEC code, redundancy packet quantities in frames in the HPP bitstream progressively decreasing from lower to higher temporal layers to which the frames belong in the HPP structure; and sorting the frames in the redundancy-coded HPP bitstream and sequentially sending the frames in the redundancy-coded HPP bitstream to a decoder side.

  • Publication number: 20180234116
    Abstract: The application discloses video data redundancy control methods and apparatuses. Video packet redundancy control information is determined according to packet loss at a reception apparatus. The video packet redundancy control information is received from the reception apparatus. Video data is encoded according to the video packet redundancy control information to obtain encoded video data of a plurality of frames by a transmission apparatus. A frame-level redundancy budget is allocated for one of the plurality of frames according to the video packet redundancy control information. Further, the one of the plurality of frames is packetized according to the frame-level redundancy budget to generate a packetized frame. Redundancy coding is performed on the packetized frame to generate video packets including data packets and redundant packets for transmission to the reception apparatus.

  • Publication number: 20180139252
    Abstract: The present disclosure provides a network call method, terminal, and server. The method includes: displaying a scenario interface for a social application group; displaying a first list of user identifiers when an instruction for initiating a specified call is received; determining, according to a selection operation in the first list of user identifiers, identifiers of second users; sending a network call request to a social application server, the network call request comprising an identifier of the first user logging in at the first terminal locally and the identifiers of the second users, so that the social application server creates a virtual group, and adds, to the virtual group, the first terminal and second terminals corresponding to the identifiers of the second users accepting call invitations; and performing a network call in a call interface for the virtual group.
