Abstract

The invention relates to a video code stream processing method and device. The method comprises: obtaining multipath original video code streams to be merged, the multipath original video code streams employing a same video coding format and possessing same code stream configuration parameters; obtaining code stream configuration parameters which are not changed in merging the multipath original video code streams, and writing changed code stream configuration parameters into a merged video code stream; copying the code stream configuration parameters which are not changed in merging the multipath original video code streams to the merged video code stream; and sequentially copying the coded data of each path of the original video code streams to a coded data container in the merged video code stream corresponding to each path of the original video code streams. The video code stream processing method and device greatly increase a video code stream merging efficiency, and can avoid video quality loss caused by video code streams in a decoding and coding process.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video code stream processing method and device. Background technique [0002] Video code stream merging is an important video processing technology, which is widely used in various application scenarios, such as the application scenario of merging left-eye and right-eye video code streams to generate 3D video code streams, multi-party video code streams in video conferencing systems merger etc. At present, video code stream merging usually firstly decodes the video code streams to be merged, obtains image data, then combines the image data, and then encodes the combined image data to obtain the merged video code stream. [0003] However, the decoding and encoding process of the video code stream is relatively complicated, and the resource consumption and time consumption are relatively large. Therefore, it is too inefficient to combine multiple video code stre...
