FFmpeg is a complete solution to record, convert and stream audio and
|
|
video. gst-plugins-ffmpeg is a FFmpeg based gstreamer plugin which
|
|
includes a vulnerable copy of FFmpeg code. Mplayer is a multimedia
|
|
player which also includes a vulnerable copy of the code.

|
|
privileges of the user running the application, or a Denial of Service.
