This video thumbnailer can be used to create thumbnails for your video files. The thumbnailer uses ffmpeg to decode frames from the video files, so supported videoformats depend on the configuration flags of ffmpeg.
This thumbnailer was designed to be as fast and lightweight as possible. The only dependencies are ffmpeg, libpng and libjpeg.
The project also includes a C/C++ library that can be used by developers to generate thumbnails in their projects

- Seeking in h264 files is enabled again, use -w option from commandline to disable this if you have 100% cpu usage (using older versions of ffmpeg)
- Give up reading packets from a file after a number of attempts to avoid a hanging ffmpegthumbnailer for certain file types (noticed on h264 and ac3 in vob container)
