- File used was sample_1238959806.avi, taken from http://www.filefront.com/13539232/sample.avi/)
- Used the following command to convert the file: ffmpeg -i sample_1238959806.avi -s 320x240 -acodec vorbis -ab 128000 -b 400000 sample_1238959806.ogg. (Note: may be preferable to replace -ab 128000 with -aq 100 which results in better audio quality. However, it increases file size to over 9 MB.)
- Some of the metadata in these tables are taken from the FFmpeg metadata that were generated during conversion. These are indicated by FFmpeg in brackets next to the value.
