Audio track missing on a certain manifest

nullket commented 2 years ago

Bug report

Describe the bug

An online provided mpd manifest does not play with audio whereas webplayers play the stream just fine.

I extracted (one of multiple available) manifest files for this random vimeo video. The manifest plays fine with online players like the reference player on dashif, but the audio track is missing when playing in kodi.

To make testing easy I created this strm file:

#KODIPROP:inputstream=inputstream.adaptive
#KODIPROP:inputstream.adaptive.manifest_type=mpd
#KODIPROP:inputstream.adaptive.license_type=com.widevine.alpha

Expected Behavior

Play a regular found mpd file from the internet with audio

Actual Behavior

Audio is missing.

To Reproduce

Steps to reproduce the behavior:

Try to play the attached mpd with the exemplary provided strm file
Check for audio

Additional context or screenshots (if appropriate)

Here is some additional context or explanation that might help:

I try to implement support for input stream adaptive for the addon plugin.video.sendtokodi. We use youtube_dl and yt_dlp to extract playable formats from URLs provided by users. When available I do not want to create a custom manifest file and use the downloadable .mpd/.m3u8 files instead.
In the case above yt_dlp provides the manifest URL with an additional ?base64_init=1 parameter like ../master.mpd?base64_init=1 I have tested playback with this original URL and the parameter stripped. Same result.

please attach the mpd file as text file, not as weblink because is expired

nullket commented 2 years ago

Sure, here is the file as a txt and the content

master.mpd

```xml ../ ```

and in case somebody is willing to install yt_dlp here is a minimal python3 example on how to get that mpds URL

minimal_vimeo_example.py

```python from yt_dlp import YoutubeDL url = "https://vimeo.com/272629446" with YoutubeDL() as ydl: ydl.add_default_info_extractors() result = ydl.extract_info(url, download=False) manifest_urls = [] # several manifests might be availbale as dash/hls/different hoster for f in result["formats"]: # search for a format having both video and audio as well as a manifest if "manifest_url" in f.keys() and f['vcodec'] != 'none' and f['acodec'] != 'none': if f['manifest_url'] not in manifest_urls: manifest_urls.append(f['manifest_url']) print(f"Your URLs\n{manifest_urls}") ```

thanks for the snippet has worked and i have saved a lot of time from a first look seem that this type of manifest is not full supported from our DASH parser because the video stream include also the audio one, also looking at the log only the video stream is sent to kodi i think we will need to implement this support

meantime when are available you can play m3u8 so HSL manifest that already have this implementation
