record rtmp with exception: avcodec_send_frame() error -541478725: Error sending a video frame for encoding #1858
Description
version: 1.5.7
I want to save the stream to MP4 file. I tried RTSP and m3u8, they are all success. But when using RTMP, I got an exception(avcodec_send_frame() error -541478725: Error sending a video frame for encoding). At first, I suspected that there was a problem with my RTMP stream, but when I changed a RTMP soure open on the Internet, the error stills there.
