ENCODING REQUIREMENTS AND RECOMMENDATIONS
In order to ensure proper playback on the Firefly, the MPEG content must be encoded following a particular set of encoding requirements. The Encoding Requirements, as well as the Encoding Recommendations, listed below provide a brief set of criteria to create MPEG files that will be compatible with the Firefly playback system.
Encoding Requirements
1.Files must be program stream MPEG2 or system stream MPEG1 of audio/video, or elementary stream MPEG2 or MPEG1 of video only or audio only.
2.Use 4:2:0, not 4:2:2 encoding.
3.In
4.Audio only (Dolby Digital or MPEG Layer 2) files cannot be mixed with files containing videos (MPEG, MPEG2 program stream, video only).
5.Firefly – Standard IDE Hard Drive): The total bit rate of a Firefly player must not exceed 40 mbps.
6.The presentation time stamp (PTS) values contained in the audio and video streams in a file must be continuous and increasing. In particular, the PTS values should not reset to 0 at any point in the file. The time between the first and last time stamps in a file should reflect the actual duration of the file.
7.Files should be no less than 4 megabytes in size. If some of your files are smaller than 4 megabytes, use an editor to combine the files to create a single file at least 4 megabytes in size.
8.Files should be no larger than 2 gigabytes in size.
