处理视频帧
我正在尝试找到执行以下功能的软件:
- 当流视频的压缩帧到达目标服务器时,在每个帧到达目标服务器后立即复制每个帧,
- 将数字化像素从一个帧复制到另一个帧内存位置
- 混合多个视频帧的数字化音频场并将结果复制到内存中
I am trying to find software that perform the following functions:
- when the compressed frames of a streamed video arrive to a destination server, make a copy of each frame as soon as it arrives at the destination server
- copy the digitized pixels from a frame to another memory location
- mix the digitized audio fields of several video frames and copy the result in memory

您的问题没有详细说明您想要实现的目标或限制是什么。您能否澄清一下这个问题,尤其是第 3 项?
FFMPEG 至少可以解决输出帧的问题(无论如何对于大多数格式),并且可以在许多平台上使用。有关示例,请参阅此处。
