[gephex-devel] [Bug 94] New: ffmpegwriter crashes when writing divx

[Martin Bayer]

Hi Sven and Mad,

there is this line in FFMpegWriter::initEncoder():

fmt = guess_format(encmap.find(encstr)->second.second.c_str(), NULL,
                    NULL);

If encstr is not in the (enc)map the "find(encstr)" returns a
encstr.end(). Dereferencing this is not allowed.

In the constructor of FFMpegWriter there is no check if the "encstr"
parameter is valid.
