"Bad src image pointers" error after calling setFrameNumber() on FFmpegFrameGrabber in JavaCV I am in the process of creating a small video editor and currently trying to get video files to display in the preview window. To do that, I want to get a frame of a video ...
Most of the times, the frames I got were black (blank), and when I grabbed each frame I got the warning of "bad src image pointers". I note that when I set the frame number first and then grab an image, it seems FFmpegFrameGrabber will return the buffered image produced during the ...
这是我第一次使用的方式,模仿 cpu 上软解码(获取视频帧,并存储为bmp格式,经验原则,这种方式最容易想到)运行结果: 失败,bad src img pointers 运行结果如下图所示: 问题原因: 如代码 hw_decode_cuvid_origin.c 中所示, 直接通过transfer_data 将gpu 中解码后的frame download到 系统内存,则系统内存中的frames ...

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 ...
