    摘要： Implementations described herein relate to methods, devices, and computer-readable media to transcode a video. In some implementations, a computer-implemented method includes obtaining a video that includes a plurality of tracks. The method further includes determining whether a partial transcoded file is available that corresponds to the video. The method further includes, if the partial transcoded file is available, obtaining a timestamp associated with the partial transcoded file, transcoding a portion of the video that begins at the timestamp associated with the partial transcoded file, and combining the partial transcoded file and the transcoded portion of the video to generate an output video. The method further includes, if the partial transcoded file is not available, transcoding the video from a start of the video using the transcoder to obtain a plurality of output tracks and combining the plurality of output tracks to obtain the output video.

    摘要： Embodiments of the present invention relate to the communications field, and provide a video distribution method and a device, so as to resolve problems of heavy IOT workload and heavy video distribution and management load when an operator and an OTT third party distribute videos by using a mobile network. The method includes: receiving, by an SCEF, a first request message sent by a third-party server, where the first request message includes an MBMS capability negotiation parameter that is used for video distribution and that is requested by the third-party server; sending, by the SCEF, a second request message to an HSS according to the first request message, to request the HSS to expose an MBMS capability; sending, by the SCEF, a third request message to a broadcast multicast service center BM-SC when the SCEF receives a second response message returned by the HSS when the HSS determines to allow the exposure of the MBMS capability, to request to obtain MBMS capability information exposed by the BM-SC; and sending the MBMS capability information obtained from the BM-SC to the third-party server, so that the third-party server requests, according to the exposed MBMS capability information, to start an MBMS broadcast, and distributes video content to UE. The embodiments of the present invention are used to support a video service by using an MBMS.
