    Yes. The element to save in single file is filesink location=/path to file/name of the file.

    Yes.

    Please what is the full use case? Is it capture->encode->save in file?

    You could try multifilesink element but set properties next-file and max-file-duration and location of course. You could check the multifilesink's properties by executing this command gst-inspect-1.0 multifilesink

    Let me know if this helps or if you have additional questions.

    Hi Margaita,

    Thanks for the reply, i have tried constructing a pipeline as follows using multifilesink, can you please check this and suggest me will this work ?

    This pipeline is to save a file for every 5mins along with timestamp

    gst-launch-1.0 v4l2src device=/dev/video0 ! timeoverlay halignment=right valignment=bottom ! clockoverlay halignment=left valignment=bottom time-format="%Y/%m/%d %H:%M:%S" ! tee name=t ! queue ! autovideosink t. ! queue ! videorate ! video/x-raw,framerate=1/300 ! ducatimpeg4enc bitrate=4000 ! multifilesink location="./video%06d.mp4" ! kmssink

    Thanks,
    Jahnavi

    Hello,

    I am sorry but your pipeline will fail.


    Please, here is example that you could try on my side it is working:

    gst-launch-1.0 -e v4l2src device=/dev/video1 io-mode=4 ! 'video/x-raw, format=(string)YUY2, width=(int)1280, height=(int)720, framerate=(fraction)30/1' ! vpe num-input-buffers=8 ! tee name=t ! queue ! ducatih264enc intra-interval=1 ! queue ! h264parse ! splitmuxsink location="save%d.mp4" muxer=mp4mux max-files=10 max-size-time=60000000000 t. ! queue ! kmssink -e

    gst-launch-1.0 playbin uri=file:///home/root/test/save1.mp4
    ...
    Execution ended after 0:01:00.006332604
    ...

    Here is the information about this pipeline and the settings that I have used:
    - v4l2src device=/dev/video1 io-mode=4 ! 'video/x-raw, format=(string)YUY2, width=(int)1280, height=(int)720, framerate=(fraction)30/1' ! ...
    The camera on my side provides the resolution, framerate and format that  are set in the capsfilter.

    - vpe num-input-buffers=8 is used since the encoder requires on his input NV12 format but my camera provides YUY2.

    - tee element will split the pipeline to two branches.

    -first branch is the encoding branch. Please notice that after the encoder there is a parser element.

    -I have used splitmuxsink element. This element will slit the video every 1 min(60000000000 this value is in nanoseconds), will save max 10 files and will mux the video into mp4 container.
    You could check here for more information:
    gstreamer.freedesktop.org/.../gst-plugins-good-plugins-splitmuxsink.html

    -Second branch is the display branch.

    Hope this helps.

    BR
