Abstract
Video parameter storage and processing techniques with MPEG-4 file format are described. In one or more implementations, techniques are described in which sequence and parameter sets are specified in-band with collections of pictures of video as the default option. Techniques are also described in which different parameter set identifiers (IDs) are specified for the collections within the video. Techniques are also described in which maximum clip parameters are specified in a sample description box. Further, techniques are described in which parameter sets are inserted at a beginning of sample data when an access unit delimiter (AUD) network access layer (NAL) unit is not present or are inserted after the AUD NAL unit in the video when present.
Claims19
A method comprising:
- receiving video at a device that includes first and second collections of pictures;
- and
- encoding the video by the device to include a first sequence and picture parameter set that is associated in-band with the first collection of pictures and a second sequence and picture parameter set that is associated in-band with the second collection of pictures.
A device comprising:
- one or more modules implemented at least partially in hardware, the one or more modules configured to perform operations comprising:
- receiving video that includes first and second collections of pictures, in which, a first sequence and picture parameter set is associated in-band with the first collection of pictures and a second sequence and picture parameter set is associated in-band with the second collection of pictures;
- and
- decoding the received video in which the first collection of pictures is decoded according to the first sequence and picture parameter set that is associated in-band with the first collection of pictures and the second collection of pictures is decoded according to the second sequence and picture parameter set that is associated in-band with the first collection of pictures.
A method comprising:
- receiving video at a device that includes first and second collections of pictures that have sequence and picture parameter sets having different values, one to another;
- and
- encoding the video by the device to include a first parameter set identifier that is associated in-band with the first collection of pictures and a second parameter set identifier that is associated in-band with the second collection of pictures.
