Problems solved by technology

Video transmission generally adopts wireless network transmission. However, due to the influence of wireless network stability and insufficient bandwidth, unreasonable packet loss is prone to occur.
[0003] When the wireless network environment is poor, it is likely that the video frames in the video frame sending queue are not sent out in time, and when the length of the video frame sending queue reaches the limit value, in the subsequent video transmission process, the video sending The video frames received by the device will be discarded directly, and the subsequent received video frames will be put into the video frame sending queue after the video frame sending queue has room for video frame sending, if the wireless network environment is poor When the duration is long, it is likely that a continuous video frame will be discarded centrally, which will cause the video frame received by the video receiving device to be incomplete, resulting in serious data loss. After decoding the video frame , what is obtained is no longer a complete video image, it is easy to appear that the video image is not clear, or even the video image is stuck, and the video playback is not smooth

Abstract

The invention discloses a video transmitting and processing method and an apparatus. The method comprises the following steps: receiving at least one video frame; according to the video frame sending sequence length and in reference to the discrepancy in the sequence length as well as a precious packet loss ratio, calculating the packet loss ratio of this time; and based on the packet loss ratio this time, determining if the received video frame(s) is / are about to be abandoned or not. According to the technical schemes provided by the invention, it is possible to adjust the packet loss ratio of video frame(s) so as to accurately determine if the video frame(s) is / are abandoned or not. As a result, improper abandonment of video frame(s) caused by only one packet loss ration can be preventable; the problem of abandoning a section of continuous video frames in concentration happening in weak internet connection can also be well addressed. As a result, the abandonment of video frames becomes more reasonable, providing a smooth playing effect even in a poor internet connection condition and avoiding unclear and stuck video pictures.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a video transmission processing method and device. Background technique [0002] With the continuous development of the Internet, people hope to transmit more multimedia information on the Internet. The transmission of video signals is the core of multimedia information transmission. Video transmission generally adopts wireless network transmission. However, due to the influence of wireless network stability and insufficient bandwidth, unreasonable packet loss is prone to occur. [0003] When the wireless network environment is poor, it is likely that the video frames in the video frame sending queue are not sent out in time, and when the length of the video frame sending queue reaches the limit value, in the subsequent video transmission process, the video sending The video frames received by the device will be discarded directly, and the subsequent receiv...
