当我使用如下命令： ffmpeg -c:v h264_rkmpp -i rtsp://admin:cssrc702@172.10.1.5:554/Streaming/Channels/01 -rtsp_transport udp -s 1920x1080 -r 20 -b:v 1000k -f rtsp rtsp://user:userpass@199.3.0.31:8554/camera1 报错： [h264_rkmpp @ 0x55b74919f0] Decoder noticed an info change (1920x1080), stride(1920x1088), format=0 Segmentation fault (core dumped) 详细log： [h264_mp4toannexb @ 0x559ad7bd50] The input looks like it is Annex B already [h264_rkmpp @ 0x559af32bb0] Initializing RKMPP decoder.

可能不支持这种图像格式，目前只针对视频文件转码做了适配，也就是常用的YUV格式才支持，如果要支持其他格式，需要知道ffmpeg格式和MPP格式的对应关系。

(1920x1080), stride(1920x1088), 看起来有stride，需要套个rescale filter预处理下？ 图片格式从你的日志看不到。需要ffprobe看一下。

ffmpeg -c:v h264_rkmpp *** -i *表示用h264_rkmpp解码，跟编码有什么关系？你要用h264_rkmpp编码的话，起码要在-i参数之后。而且仔细看wiki中的示例命令，只要是硬件编码，一律使用scale_rga过滤器。
