/* 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)
