Hi Pino,

Sorry I am not good at English language, I am inputting slowly try to express
clearly, please wait for minutes patiently :)

Please help me to check
https://github.com/KDE/k3b/blob/master/plugins/decoder/ffmpeg/k3bffmpegwrapper.cpp#L289

I argue that it might be:

1. Memory copy function accesses out-of-bound array element
2. Memory copy function overflows destination buffer
3. Memory copy function accesses out-of-bound array element
4. Memory copy function overflows destination buffer
5. overlapping
6. Null pointer argument in call to memory copy function

But my sincere thanks goes to you for maintaining ffmpeg plugin
