#675 FFMPEG segfault on default recording

[SlagDog]

Expectation does not seem to be met at all. Saving a media file with ffmpeg should actually start recording to the defined file format and not stop until emulator exit (or entering the "save media file" menu again and stop recording) - at least that is what I remember from previous behaviour.

Used OS is (old) Ubuntu 12.04 - yasm 1.2 from source.

Start "x64sc" under linux - compiled with:

./configure --enable-gnomeui --enable-memmap --enable-ethernet --enable-fullscreen **--enable-shared-ffmpeg** --with-arts --disable-vte && make clean && make -s

and then installed.

A similar crash happens using "--enable-static-ffmpeg". shared-ffmpeg has a few more problems when actually installing the libraries, but thats a different issue.

"Save media file" -> "choose FFMPEG" -> leave options at default (mp3 sound, mp4 video) -> give path/filename -> instantly returns "file saved" requester (be puzzled) - pressing "ok" leads to this crash:
