Thank you for reply.
frame.c:
int av_frame_ref(AVFrame *dst, const AVFrame *src)
{
...
/* duplicate the frame data if it's not refcounted */
if (!src->buf[0]) {
ret = av_frame_get_buffer(dst, 32);
if (ret < 0)
return ret;
ret = av_frame_copy(dst, src);
if (ret < 0)
av_frame_unref(dst);
return ret;
}
...
}
After avcodec_decode_video2 my frame is not refcounted, so call of av_frame_ref
gives me copy of frame.
I just want to my frame is refcounted. How to make this?
