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 discoverer fuzzing target
|
|
*
|
|
* This application can be compiled with libFuzzer to simulate
|
|
* a push-based discoverer execution.
|
|
*
|
|
* To reproduce the failing behaviour, use:
|
|
* $ gst-discoverer-1.0 pushfile:///...
|
|
*
|
|
* The goal is to cover basic usage of demuxers, parsers and
|
|
* base decoder elements.
|
|
*
|
|
* When compiling, only link the required demuxer/parser/decoder
|
|
* plugins and keep it to a limited range (ex: ogg/theora/vorbis)
|
