You would have a relatively recent version of libquicktime on your system, right? Somewhere between version 0.9.7 and 0.9.10 the API changed slightly to prevent direct access to fields in the quicktime_t structure. Therefore, since mjpegtools 1.8.0 was released before this API change the contents of line 1370 are now not valid because the *quicktime_t pointer is being dereferenced: res = fileno(((quicktime_t *)lav_file->qt_fd)->stream); The fix is to change this line to something like res = lqt_fileno(lav_file->qt_fd); I suspect this has already been done in svn since libquicktime 0.9.10 has been out for quite some time now. On a related note, does anyone know why the qt_fd field of lav_file_t is a void* rather than a quicktime_t*, especially given that avi_fd is an avi_t* ? Is it reused for other purposes (which seems odd since a separate avi_t* field was created for avifile interaction). Why can't we make it a quicktime_t* ?
