Main differences with previous setup are: - No manifest creation - gst-indent is executed only when the bot is assigned (instead of the manifest task) - Cerbero jobs are triggered in the cerbero repo - Remove cerbero and android related files as they now are in cerbero itself. - Update `container.ps1` to the new file layout Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/891>

/* push-based typefind fuzzing target

|
|
* This application can be compiled with libFuzzer to simulate
|
|
* a push-based typefind execution.
|

|
|
* To reproduce the failing behaviour, use:
|
|
* $ gst-launch-1.0 pushfile:///.. ! typefind ! fakesink
|
|

|
|
* The goal is to cover typefind code and implementation.
