Splitmuxsink Restart Record File Name Index Problem

[Alpha.Chen]

Hi,
I try use gstreamer+python
use splitmuxsink split record file,
But when I restart the app,
the file name can’t continue,
It’s overwrite of first file.

And I try theese pipeline use start-index :

...
 # 檢查現有檔案數量以獲取正確的起始索引
    output_dir = f"{record_path}/{camera_number}/"
    existing_files = [f for f in os.listdir(output_dir) if f.startswith(f"output_{camera_number}_") and f.endswith(".mp4")]
    start_index = len(existing_files)

    gst_out = (
        f"appsrc ! video/x-raw, format=BGR ! queue ! videoconvert ! nvvidconv ! "
        f"videorate max-rate={record_fps} ! nvv4l2h264enc  insert-sps-pps=true idrinterval=15  control-rate=0 ! h264parse ! "
        f"splitmuxsink  location={record_path}/{camera_number}/output_{camera_number}_%03d.mp4 max-size-time={max_size_time*Gst.SECOND*60} max-files={max_video_files_length} " 
        f"start-index={start_index} next-file=4"  # 4 = GST_SPLITMUX_NEXT_FILE_MAX
    )
    writer = cv2.VideoWriter(gst_out, cv2.CAP_GSTREAMER, 30,frame_shape[1::-1])
...

But the write file still from first file,
I want to continue last file name to next,

Ex:
Last file name is : out_000.mp4
And I restart the app.
Then record file will start in out_001.mp4

How can I do?
Thanks!

Hi,
You may try the pipeline in gst-launch-1.0 command. We run the command and don’t hit the issue:

$ gst-launch-1.0 -e videotestsrc is-live=1 ! video/x-raw, format=BGR ! queue ! videoconvert ! nvvidconv ! nvv4l2h264enc  insert-sps-pps=true idrinterval=15  control-rate=0 ! h264parse ! splitmuxsink location=video%03d.mp4 muxer=qtmux start-index=5

I try to use theese pipeline direct run on gstreamer,
But the save file not begin on video005,
It’s still video000.

pipline and output:

ubuntu@EAC-5000:~/workspaces/yolov8-for-jetson/opencv$ gst-launch-1.0 -e videotestsrc is-live=1 ! video/x-raw, format=BGR ! queue ! videoconvert ! nvvidconv ! nvv4l2h264enc  insert-sps-pps=true idrinterval=15  control-rate=0 ! h264parse ! splitmuxsink location=video%03d.mp4 muxer=qtmux start-index=5

Hi,
We run the command on developer kit and can see index starting from 5. Are you able to try developer kit?

Not sure if it helps but you can clean the cache for a try:

$ rm ~/.cache/gstreamer-1.0/registry.aarch64.bin

Does not work.😅

Hi,
It looks the property start-index is not supported on gstreamer 1.16.3. We searched online and found the solution:
gstreamer - Is it possible to set initial index of splitmuxsink? - Stack Overflow

You may give it a try.

All right,I will be try it,
But maybe a few days later.
Thanks!
