根据播放表现,我觉得是读取网络数据的缓冲(buffer size)过小的原因,但是vlc-android播放视频在android层就一个readmedia接口,并没有设置参数的函数,所以第一反应是通过修改vlc的源代码,然后重新编译库文件,达到修改buffer size的目的。
data, but for string. You set it by adding the "--imem-cookie=<your_string>" option when you initialize VLC. Use this when multiple VLC instances are running. \param[int] bufferSize The size of the buffer in bytes. \param[out] buffer Pointer to data you allocated or set during the ...

时钟组件主要由input_clock_t结构体和相关函数组成,如:input_clock_SetRate函数。input_clock_SetRate函数用于修改内部时钟频率,从而实现不同的播放速率。 解码器(decoder)层 解码器负责将原始数据流解码为音频或视频输出。在这个过程中,解码器需要根据输入读取器的时钟频率调整解码速度。例如,在音频解码器中,解码器会...

av_image_get_buffer_size计算了计算图像数据的缓冲区大小。av_malloc分配了1个内存块给showBuffer。av_image_fill_arrays用图像参数和showBuffer初始化AVFrame的data和linesize成员,并且让AVFrame和showBuffer关联。 while(av_read_frame(streamFmtCtx, packet) >= 0){ ...
