Common media library:
Overview:
- The CML is a JS/TS library. Some RUST work.
- Purpose: consolidate standards-based features into one library. One source of truth.
- Modularity: Every single class / utility function is independent. You can import the functions you need.
- License: Apache 2
Current functions:
- CMCD
- CMSD
- 608 captions
- id3 data tags
Players:
Next:
- Integrate on Shaka (solve NPM). Joey is willing to do that!
- 708 captions
- Captions rendering (consistent rendering on players, browsers, TVs?)
- CMAF HAM
Discussion:
- Will Law: Are other players integrating this? (theo, bitmovin, video.js, etc.)
- Luke Curley: Are you thinking about porting to non-web players?
- Subtitles and captions rendering challenges
- Discussions around WASM vs JS
- Test cases: becomes a valuable part of the library
- Alex Z: Do you see CML intended for MSE based players or extended to native players?
- Will L.: Why do we have so many open-source players? Is there a future of a shared player that has a common interface? Is there a push in that direction. Some players perform better than others on different platforms.
- Production vs. Reference players
- Heff: There’s no one-size fits all
Common Error codes:
Overview:
- A lot of players out there
- Motivation came from QoE? group
- When you are looking at error codes on the backend, it’s difficult to realize what it is if you don’t know which player it came from.
- Standardized error codes, 5 or 6 digits
- Is the WG focused on identifying the error cases?
- QoE? people working on the back-end identifying what’s being received
- Player group working on what the player is spitting out
Discussion:
- Joey: Having significant digits on the left representing the error category and on the right for specific error cores. Having a common set would be great
- Will: would commercial players be willing to implement this?
- Chromium: tried something similar, but it’s a huge fingerprinting.They have a few 1000s different error codes. They are limited to what they can say to js.
- Will: There are 60+ ways to report a media-report error.
Aspects:
- figuring out categories
- players vs. lower platforms
