1169559 - Implement Audio Splice Frame Algorithm

Status: NEW

(Core :: Audio/Video: Playback, defect)

Description

[Jean-Yves Avenard [:jya]]

Part of the MSE spec:
http://w3c.github.io/media-source/index.html#sourcebuffer-audio-splice-frame-algorithm

When audio data is appended to a source buffer and is about to replace an existing range of audio, the overlapped frames are supposed to be spliced according to the audio splice frame algorithm.

I got an idea on how this could be very easily implemented without much overhead in the new MSE architecture (bug 1119208)

This bug is about supporting cross-fading, and not just the "splicing"

Comment 2

Is there anything blocking this bug?

someone to write the code maybe?

That would involved either:
1- decoding the data as it's being added so that the cross-fading is done during appendBuffer phase
2- Do it at playback time.

In any case, it's not compulsory, and I'm not sure we should care about it.
