摘要
实现了对松下P2素材进行剪辑的功能模块,所涉及文件格式包括MXF,DV,AVCI,MP4,MPEG-4。为达到高效剪辑,采用了MPEG-4帧类型转换、多线程文件读写以及内存映射技术,剪辑均达到了帧精度,耗时短,效果良好。
An efficient module clipping of P2 material is realized, The formats of material include MXF, DV, AVCI, MP4, MPEG-4. For the enhancement of efficiency, several techniques such as MPEG-4 frame type transforming, multi-thread file I/0 and memory mapping are employed. Meanwhile, the module achieves short-time consuming and frame precision respectively.
