1423248 - Don't use VideoChunk durations when producing and consuming video

Status: RESOLVED DUPLICATE of bug 1423253

(Core :: Audio/Video: MediaStreamGraph, enhancement, P2)

Description

[Andreas Pehrson [:pehrsons]]

Currently we have MediaSegment as a base class for both AudioSegment and VideoSegment. This means AudioSegments and VideoSegments work the same way -- they have chunks with durations. The sum of the duration for all chunks is the duration of the segment.

We are moving away from video durations already, we have timestamps for VideoChunks and several consumers have moved to use timestamps to some extent.

First we'll have to stop using durations when both producing and consuming VideoSegments. This includes porting any consumers still using durations over to timestamps.

We can still use it internally in the graph for bookkeeping of tracks. Taking durations out completely would be a larger operation we can do later.

This is happening in bug 1423253.
