gssink

Write incoming data to a series of sequentially-named remote files on a Google Cloud Storage bucket.

The object-name property should contain a string with a %d placeholder that will be substituted with the index for each filename.

If the property is TRUE, it sends an application message named GstGsSink after writing each buffer.

The message's structure contains these fields:

  • gchararray filename: the filename where the buffer was written.
  • gchararray date: the date of the current buffer, NULL if no start date is provided.
  • gint index: index of the buffer.
  • GstClockTime timestamp: the timestamp of the buffer.
  • GstClockTime stream-time: the stream time of the buffer.
  • GstClockTime running-time: the running_time of the buffer.
  • GstClockTime duration: the duration of the buffer.
  • guint64 offset: the offset of the buffer that triggered the message.
  • guint64 offset-end: the offset-end of the buffer that triggered the message.

Example launch line

gst-launch-1.0 videotestsrc num-buffers=15 ! pngenc ! gssink
object-name="mypath/myframes/frame%05d.png" bucket-name="mybucket"
next-file=buffer post-messages=true

Upload 15 png images into gs://mybucket/mypath/myframes/ where the file

names are frame00000.png, frame00001.png, ..., frame00014.png

gst-launch-1.0 videotestsrc num-buffers=6 ! video/x-raw, framerate=2/1 !
pngenc ! gssink start-date="2020-04-16T08:55:03Z"
object-name="mypath/myframes/im_%s_%03d.png" bucket-name="mybucket"
next-file=buffer post-messages=true

Upload png 6 images into gs://mybucket/mypath/myframes/ where the file

names are im_2020-04-16T08:55:03Z_000.png, im_2020-04-16T08:55:03Z_001.png, im_2020-04-16T08:55:04Z_002.png, im_2020-04-16T08:55:04Z_003.png, im_2020-04-16T08:55:05Z_004.png, im_2020-04-16T08:55:05Z_005.png.

gst-launch-1.0 filesrc location=some_video.mp4 ! gssink
object-name="mypath/myvideos/video.mp4" bucket-name="mybucket" next-file=none

Upload any stream as a single file into Google Cloud Storage. Similar as

filesink in this case. The file is then accessible from: gs://mybucket/mypath/myvideos/video.mp4
