[Q] Prepare DASH file for audio #105

Closed stefan-falk closed 2 years ago

stefan-falk commented 2 years ago

Coming from https://github.com/google/shaka-player/issues/3846

@joeyparrish Okay after giving it a closer read I think I'm getting my head around this. Slightly.

What I understood so far is that I want to convert any audio file e.g. WAV or MP3 into a DASH file. This file is going to get stored in my GCS and the shaka-player will then be able to play that DASH file from there.

My question here would be which config files I would be using for that?

Looking at bitrate_config.yaml, would I just remove the video_resolutions part?

How can I e.g. support different kind of input-files (wav, mp3, mp4) to be converted and what pipeline-config would I use for that?

Sorry for the delay in my response!

You can use the default bitrate config, and just create at a minimum a pipeline config and an input config.

An input config says "this is what my input is and where it comes from".

A pipeline config says "this is how I want things encoded". A single pipeline config could be reused for multiple inputs. A streaming service might end up with one pipeline config for VOD, maybe a different one for live streams, and perhaps a third for audio-only content.

You can start from some of our example configs for input and pipeline, and/or refer to the documentation for the config formats to see a full list of what options there are. I would suggest basing your input on config_files/input_vod_config.yaml (just the audio object, the second one in the file), and base your pipeline on config_files/pipeline_vod_config.yaml (resolutions and video_codecs don't matter for you).

Does this help?
