Option to force video detection regardless of codecs in manifest?

[deltafactory]

Description

This is a request for compatibility in situations where the HLS provider does not accurately specify codecs in the media chunks. In my situation, my HLS provider offered the following as one of the options even though the media included a properly encoded video stream.

#EXT-X-STREAM-INF:BANDWIDTH=2846000,CODECS="mp4a.40.2"

VLC and JWPlayer both found and displayed the video components of these streams. I have confirmed that the manifest received by each were incorrect using Wireshark (VLC) and browser dev tools (JWPlayer).

Sources

A different example (perhaps with the same cause) can be found here: https://www.wowza.com/community/questions/50063/ndvr-avc-codec-missing-in-hls-playlist.html

Steps to reproduce

I will provide a test case if I can determine the cause. should be created by modifying the master playlist of a static stream. The online test player can be used to reproduce: https://videojs.github.io/http-streaming/

Results

Expected

As a feature request, I would like an option to force video (specify the codec params?) during the source setup. Alternately, the missing media track could be detected automatically.

Error output

N/A - video.js is technically correct.

That's an interesting idea and we'll consider it. Right now we're trying to wrap up work on getting what's in master shipped.
