Note that VDPAU cannot be used to decode frames in memory, the compressed frames are sent by libavcodec to the GPU device supported by VDPAU and then the decoded image can be accessed using the VDPAU API. This is not done automatically by FFmpeg, but must be done at the application level...

1、avcodec_register_all avcodec_register_all用于注册所有可用的编解码器。在使用FFmpeg进行音视频处理之前,通常需要调用这个函数来初始化并注册编解码器。函数原型如下: void avcodec_register_all(void); 调…
在多媒体播放中,我们需要处理的基本组成部分包括音频和视频数据。这些数据通常以压缩的形式存储,需要进行解码才能播放。解码后的数据通常以帧(frame)的形式表示,每一帧代表一个时间点的音频或视频数据。 1.1 多媒体播放的基本组成部分 在音视频处理中,我们主要处理的是音频帧和视频帧。音频帧(Audio Frame)和视频帧(...
but it is giving me some bad image, and in some cases it is not giving any image. * So please anybody tell me where i am doing wrong.Thanks!! EDIT: Sometimes it gives me error like[swscaler @ 0x1c9a6e0] bad src image pointers ...
