Inspect HLS Video Segment #83

Open ericxtang opened 6 years ago

ericxtang commented 6 years ago

Is your feature request related to a problem? Please describe. We don't know the parameters of an video segment.

Describe the solution you'd like To implement a video inspector that returns parameters about a HLSSegment.

What we want to understand:

We want to implement a vidInspector/inspector.go with a single Inspect method that takes a HLSSegment and returns the above parameters. For inspirations, check out lpms_length. You should follow the example of ffmpeg.go, possibly adding functions to it (by adding to the native libav integration).

Describe alternatives you've considered We can also implement an inspector for the RTMP stream, but doing the check for the HLS segment can be used on the broadcaster and the transcoder.

Additional context We are planning to use this inspector to inspect incoming videos, and automatically make choices about the ABR list.

We assume the video parameters will remain the same throughout the entire video. In practice, we'll probably examine the first segment of the video after the RTMP video is segmented into HLS, or if the input is in HLS, simply inspect the first segment.

Important to note is that this should not come from the video metadata but rather the video itself like ffprobe is doing it. I guess it means inspecting the NAL units and really see what is in there.
