Abstract: The disclosure discloses a system and method for real-time adjustment of a volume during live broadcasting, the system being arranged in a live broadcasting backend, wherein the system includes a transcoder and a volume adjusting device, wherein the transcoder includes a decoding unit and an encoding unit, wherein the decoding unit is configured to decode in real time a live broadcasting audio and video uploaded to the live broadcasting backend into original audio and video signals; and the encoding unit is configured to encode in real time the original audio and video signals into encoded audio and video signals; and the volume adjusting device is arranged between the decoding unit and the encoding unit, and configured to adjust the volume of the original audio signal output by the decoding unit to the encoding unit, in response to a volume adjusting instruction.

Abstract: The disclosure discloses a method and device for allocating a transcoding task, the method including: obtaining the transcoding task to be allocated; determining the number of standard processing units to be occupied by the transcoding task to be allocated; obtaining current load states of respective transcoders; selecting a target transcoder according to the number of standard processing units to be occupied for the transcoding task to be allocated, and the current load states of the respective transcoders so that the load state of the target transcoder to which the transcoding task to be allocated has been added is still in a normal state; allocating the transcoding task to be allocated, to the target transcoder; and updating the current load state of the target transcoder.

Abstract: Disclosed are a transcoding method and electronic apparatus. The method includes: obtaining 16 H.264 video macro blocks; determining encoding type of the 16 H.264 video macro blocks; transcoding the 16 H.264 video macro blocks into a H.265 coding tree unit CTU according to preset intra-frame transcoding correspondence if the encoding type of the 16 H.264 video macro blocks is intra-frame coding; transcoding the 16 H.264 video macro blocks into one H.265 CTU according to preset inter-frame transcoding correspondence if the encoding type of the 16 H.264 video macro blocks is inter-frame coding. The device includes: capturing module, determination module, first transcoding module and second transcoding module. The present invention has no need to decode H.264 video macro blocks to produce original video data, so the transcoding process can speed up and save time.

Abstract: Disclosed is a video transcoding method which enhances the efficiency of segmentation transcoding, including: performing frame rate conversion analysis on a video to obtain result information of frame rate conversion and position information of an IDR frame, and dividing the video into first video clips according to the position information of the IDR frame; splicing all the first video clips to produce second video clips according to chronological order and preset rule; encoding all the second video clips to obtain statistical file of the video according to the result information of frame rate conversion; determining scene switching position of the video according to predetermined frame type of the statistical file; splicing all the first video clips to produce third video clips according to the scene switching position; encoding and splicing all the third video clips to produce a complete video file according to the result information of frame rate conversion.

Abstract: The embodiment of the present disclosure provides a method for removing video watermarks, wherein the method includes: finding out a watermark region in a video and selecting a proper watermark expansion region, and copying the pixels of the watermark expansion region to form a mask region; extending the watermark region in an original video frame to form a stuffing region, and using pixels beside the stuffing region to stuff the watermark region to acquire a video frame after stuffing; and performing blur processing on the mask region, and finally superposing the video frame after stuffing with the mask region after blur processing, thus being capable of removing the watermarks completely, and ensuring the smooth transition between the watermark-removed region and a surrounding region in the meanwhile
