iOS-VideoToolBox-demo iOS VideoToolBox encode&decode demo 详细讲解：

硬件解码器 本课演示如何使用VideoToolbox进行iOS硬件解码 硬件解码器步骤 // 1. Get SPS,PPS form stream data, and create CMFormatDescription, VTDecompressionSession // 2. create CMFormatDescription // 3. create VTDecompressionSession // 4. get NALUnit payload into a CMBlockBuffer // 5. making sure to replace the separator code with a 4 byte length code (the length of the NalUnit including the unit code) // 6. create a CMSam
