-## OpenDLV Microservice to decode video frames from VP8 or VP9 into a shared memory
+## Microservice to transform an input image in (A)RGB/(A)BGR format to I420
 
-This repository provides source code to decode broadcasted video frames in
-VP8 or VP9 format into a shared memory area for the OpenDLV software ecosystem.
+This repository provides source code to transform an input image in (A)RGB/(A)BGR
+format residing in a shared memory to an image in I420 residing in a new shared
+memory suitable for subsequent video compression.

-As this microservice is connecting to an OD4Session to receive VP8 or VP9 frames
-to decode them into a shared memory area using SysV IPC, the `docker-compose.yml`
-file specifies the use of `ipc:host`. The parameter `network_mode: "host"` is
-necessary to receive VP8 or VP9 frames broadcasted from other microservices running
-in an `OD4Session` from OpenDLV. The folder `/tmp` is shared into the Docker
-container to provide tokens describing the shared memory area.
+As this microservice is connecting to an existing shared memory to read the (A)RGB/(A)BGR
+image for transform it into a new shared memory area using SysV IPC, the `docker-compose.yml`
+file specifies the use of `ipc:host`. The folder `/tmp` is shared into the Docker
+container to provide tokens describing the shared memory areas.
 The parameters to the application are:
 
-* `--cid=111`: Identifier of the OD4Session to listen for VP8 or VP9 frames
-* `--id=2`: Optional identifier to listen only for those VP8 or VP9 frames with the matching senderStamp of the OD4Session
-* `--name=XYZ`: Name of the shared memory area to create for storing the ARGB image data
+* `--in`: Name of the shared memory area containing the (A)RBG/(A)BGR image
+* `--out`: Name of the shared memory area to be created for the I420 image
+* `--width`: Width of the input image
+* `--height`: Height of the input image
+* `--argb`: Format of the input image (choose exactly one!)
+* `--rgb`: Format of the input image (choose exactly one!)
+* `--abgr`: Format of the input image (choose exactly one!)
+* `--bgr`: Format of the input image (choose exactly one!)
 * `--verbose`: Display decoding information and render the image to screen (requires X11; run `xhost +` to allow access to you X11 server)
