Very short audio gaps at the start of video

[mb555444]

Hi

I'd like to report an issue with this plugin that I have been having for a long time, i.e. also with older versions e.g. on Kodi 19 but also on the latest version. If I watch e.g. a news programme such as ZIB2 on ORF, in the first few seconds there is a short but noticable gap in the audio. This usually means that a part of a word spoken by the news speaker is skipped.

Steps to reproduce:

• install Kodi and the addon (default settings)
• start the add-on, choose e.g. "ZIB2" or "ZIB1" from "recently added shows"
• select a single news entry
• listen carefully during the first 5 seconds, it frequently happens (but only once per video and only in the first few seconds) that a short part of a spoken word is not hearable (e.g. instead of "Wirtschaftsforscher" you hear ("Wir.forscher")
• if not reproducible at first try, try again with a different news item

For clarification: the missing audio is not replaced by silence but cut out.

I can reproduce this both on Kodi on a Fire TV Cube as well as on my Android phone.
There is no noticable gap in the video, just the audio.

Unfortunately I do not know if the issue is in the addon or in Kodi but I only notice it with this addon. It does not occur when watching ORF with the ORF TVThek App or Joyn.

Hi - is there any feedback on this issue?

sorry for the late reply. i also have experienced this issue on almost any OS. weirdly the gap doesn't occur on a second try (at least most of the time ;)) so if i restart the same video again the audio is fine. i think this might be an issue with inputstream adaptive and/or ffmpeg. there's nothing i can do about it in the addon scope unfortunately.

Thanks for the response. Do you know if it is possible to narrow down the issue and collect more info, so it can be reported to the right upstream developers?

i think this only happens on drm content. attached you'll find a log file from streaming a live channel. on line 290 and 329 there are decryption errors which might cause this problem but i am not sure.
