I create a pipeline by refering to deepstream-apps with version 4.0.1 ,like this, “rtspsrc->rtph264depay->decodebin->fakesink” . I add probe at sink pad of fakesink to get GstBuffer. Sometimes, stream is not not runing. Below is log. I need help of somebody. Thanks. cb_rtspsrc_select_stream==video cb_rtspsrc_select_stream==audio 0:00:43.268143482 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:191:gst_rtp_h264_depay_negotiate: allowed caps: video/x-h264, stream-format=(string)avc, alignment=(string)au; video/x-h264, stream-format=(string)byte-stream, alignment=(string){ nal, au } 0:00:43.269777739 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:223:gst_rtp_h264_depay_negotiate: downstream requires byte-stream 0 0:00:43.269907693 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:231:gst_rtp_h264_depay_negotiate: downstream requires merge 1 0:00:43.270050094 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:704:gst_rtp_h264_depay_setcaps: we have 2 params 0:00:43.270380690 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:726:gst_rtp_h264_depay_setcaps: adding param 0 as SPS 0:00:43.270461107 5706 0x7ec0004540 LOG rtph264depay gstrtph264depay.c:559:gst_rtp_h264_add_sps_pps: Adding new SPS 0 0:00:43.270803287 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:726:gst_rtp_h264_depay_setcaps: adding param 1 as PPS 0:00:43.270898136 5706 0x7ec0004540 LOG rtph264depay gstrtph264depay.c:599:gst_rtp_h264_add_sps_pps: Adding new PPS 0:0 0:00:43.271057337 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:386:gst_rtp_h264_set_src_caps: copy SPS 0 of length 16 0:00:43.271183483 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:402:gst_rtp_h264_set_src_caps: copy PPS 0 of length 4 decodebin child: h264parse1 decodebin child: capsfilter1 0:00:43.286202782 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:292:gst_rtp_h264_depay_set_output_caps: downstream ALLOCATION query failed 0:00:43.286387872 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:1027:gst_rtp_h264_depay_process: receiving 5 bytes 0:00:43.286419232 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:1047:gst_rtp_h264_depay_process: NRI 0, Type 6 0:00:43.286457057 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:845:gst_rtp_h264_depay_handle_nal: handle NAL type 6 0:00:43.286475745 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:914:gst_rtp_h264_depay_handle_nal: adding NAL to picture adapter 0:00:43.286498337 5706 0x7ec0004540 DEBUG rtph264depay gstrtph264depay.c:779:gst_rtp_h264_complete_au: taking completed AU 0:00:43.286515970 5706 0x7ec0004540 LOG rtph264depay gstrtph264depay.c:757:gst_rtp_h264_depay_allocate_output_buffer: want output buffer of 9 bytes decodebin child: nvv4l2decoder1 Opening in BLOCKING MODE NvMMLiteOpen : Block : BlockType = 261 NVMEDIA: Reading vendor.tegra.display-size : status: 6 NvMMLiteBlockCreate : Block : BlockType = 261

Hi, May see if some others can share experience. Or you may try uridecodebin ! nvoverlaysink

Hi, There is a sample which is close to your usecase. Please check [image] How to run RTP Camera in deepstream on Nano DeepStream SDK Hi, We are checking the issue. Since we do not have the IP cameras you have, please help run attached app and share the print: bufferformat: NvBufferColorFormat_NV12 Please modify rtsp location in the code and execute the steps: $ export MMAPI_INCLUDE=/usr/src/tegra_multimedia_api/include $ export MMAPI_CLASS=/usr/src/tegra_multimedia_api/samples/common/classes $ export USR_LIB=/usr/lib/aarch64-linux-gnu $ g++ -Wall -std=c++11 decode.cpp -o decode $(pkg-config --cflags --libs gstreamer-app-…

That sample is different from my case. It has no reference value.
