The saved video is correct, but the image saved from the buffer is wrong. The saved image is an image from another stream. I commented out the video storage function at 10s intervals from lines 1070 to 1078 in deepstream_source_bin.c. Secondly, the function of starting to save videos in my code is…

Where did you add the code? Since the image in the NvBufSurface is batched, you need to find the corresponding picture in the batch to save.

static GstPadProbeReturn analytics_done_buf_prob_renjifei(GstPad *pad, GstPadProbeInfo *info, gpointer u_data){ // NvDsInstanceBin *bin = (NvDsInstanceBin *) u_data; // guint index = bin->index; AppCtx *appCtx = (AppCtx *) u_data; GstBuffer *buf = (GstBuffer *) info…

The images and videos that are continuously streaming are consistent, but inconsistencies will occur as long as the streaming is interrupted.

[image] challengesll: the streaming is interrupted OK. What exactly does the “interrupted” refer to here? Also could you try to set the macro below to see if it works? Thanks export USE_NEW_NVSTREAMMUX=yes

The “interrupted” here refers to the disconnection of the video stream. Mainly to simulate actual flow interruption scenarios.

OK. So have you tried setting the environment variable export USE_NEW_NVSTREAMMUX=yes ?

[image] I set the environment variable export USE_NEW_NVSTREAMMUX=yes, but it will cause the program to block. The source 0 push stream here is connected normally.

It’s werid. I run our demo code, it works well. [image] challengesll: Is the image taken from NvBufSurface based on the batch_id of frame_meta? Because the batch_id I obtained in getImg is wrong, the image obtained is wrong. How can I get the real batch_id of frame_meta? If you want to tell…

I want to take out the frame image of the video stream from the buffer and save it as an image in JPG format. [image] yuweiw: It’s werid. I run our demo code, it works well. If you want to tell which video source it comes from, you need to use source_id instead of batch_id. Is it normal to…
