Sample accurate WEBM timestamps

Features

• Extract codec parsing to it's own library: codec-parser
  • Resolves #7

Breaking Changes

• Default maxFramesPerSegment to 50.
  • This helps with Vorbis clicks and pops in Firefox.
• Default to webm for preferred container
  • Webm is able to play Opus streams without skips in Chrome and is better suited as a default option.

Fixes

• Use sample rate as TimestampScale for sample accurate timing on Webm timestamps.
  • Resolves #5
• Vorbis clicks and pops were partially because of rounding errors when calculating the timestamp based on milliseconds.
  • Resolves #4

Safari compatibility for fMP4

feat: patch release

Add onMimetype callback

• Add onMimeType callback to notify consumer when the output mimetype has been determined while still reading data.

Add WEBM support

Breaking Changes

• NPM package from isobmff-audio to mse-audio-wrapper
• Rename repository isobmff-audio to mse-audio-wrapper
• mimeType getter for Ogg streams is available only after the Ogg identification header has been read

Features

• Adds WEBM for Opus and Vorbis codecs

Options

• Adds mimeType getters
• Adds preferredContainer option to choose between ISOBMFF or WEBM for codecs that support both (i.e. Opus)
• Adds onCodecUpdate callback option that is called when the codec header information has changed
• Adds maxFramesPerSegment option to limit how many frames can be returned in a single media segment. Fixes an issue where over roughly 50 blocks in a cluster causes errors for WEBM.

Performance

• Adds caching for codec headers that have already been parsed
• Simplifies TypedArray operations to shared functions, and other various minor enhancements

Fixes

• Fixes header mutation issue with codecs in an ogg container where the same object reference was being mutated by mistake
• Fixes issue where parser drops frames if there isn't enough data to completely parse a header
• Fixes ogg parsing when there is extra data not described in the page segment table

Known issues

• Vorbis skips and pops intermittently in Firefox, but works fine in Chrome. An issue will be added to address this.

Fix Opus sample lengths in trun box

0.1.1

fix: Opus sampleLength in trun box

Add Ogg Opus Support

• Add Ogg Opus support
• Significantly speed up FLAC parsing by using Ogg lacing values to determine frame size

Initial NPM Release

• Parses (MP3, AAC, or OGG Flac) and outputs fragmented ISOBMFF
