摘要： A container format processing tool performs syntax-aware manipulation of hierarchically organized syntax elements defined according to a container format in a media file. For example, a container format verifier checks conformance of a media file to a container format, which can help ensure interoperability between diverse sources of media content and playback equipment. Conformance verification can include verification of individual syntax elements, cross-verification, verification that any mandatory syntax elements are present and/or verification of synchronization. Or, a container format “fuzzer” simulates corruption of a media file, which can help test the resilience of playback equipment to errors in the media files. The container format fuzzer can simulate random bit flipping errors, an audio recording failure or incorrect termination of recording. Or, a container format editor can otherwise edit the media file in the container format.

摘要： Techniques are described for inserting encoded markers into encoded audio-video content. For example, encoded audio-video content can be received and corresponding encoded audio and video markers can be inserted. The encoded audio and video markers can be inserted without changing the overall duration of the encoded audio and video streams and without changing most or all of the properties of the encoded audio and video streams. Corresponding encoded audio and video markers can be inserted at multiple locations (e.g., sync locations) in the encoded audio and video streams. Audio-video synchronization testing can be performed using encoded audio-video content with inserted encoded audio-video markers.

摘要： A media processing comparison system (“MPCS”) and techniques facilitate concurrent, subjective quality comparisons between media presentations produced by different instances of media processing components performing the same functions (for example, instances of media processing components in the form of hardware, software, and/or firmware, such as parsers, codecs, decryptors, and/or demultiplexers, supplied by the same or different entities) in a particular media content player. The MPCS receives an ordered stream of encoded media samples from a media source, and decodes a particular encoded media sample using two or more different instances of media processing components. A single renderer renders and/or coordinates the synchronous presentation of decoded media samples from each instance of media processing component(s) as separate media presentations. The media presentations may be subjectively compared and/or selected for storage by a user in a sample-by-sample manner.
