No chapters or pictures in audio podcast

egabosh commented 2 years ago

Moin, I don't see any pictures or chapters provided with an audio-podcast. It should be reproduceable with this feed: https://feeds.lagedernation.org/feeds/ldn-aac.xml Pictures are provided in this sequence "LdN274 Raus aus der Flaute: Windkraftausbau in Deutschland (Teil 1/2)" I'm using the lastest version from F-Droid (https://f-droid.org/de/packages/de.luhmer.owncloudnewsreader/) with Android 11 (LineageOS). In the AntennaPod-App (https://f-droid.org/de/packages/de.danoeh.antennapod/) it works but the app has no Nextcloud-Support. Please help/fix! And thank you for your great work!

Thank you for your feedback! I'll have a look into why the pictures are not showing up! Chapters are unfortunately not supported as of now.

David-Development commented 2 years ago

I'm just looking into the feed that you provided. Which pictures do you expect to show up and where?

From what I can see the feed does not provide any pictures itself (just plain text with many links).

Even in the Nextcloud News Web App I cannot see any images.

egabosh commented 2 years ago

Yes, there are no pictures in that page, thats right. But thats not my point. If you play the podcast with the AntennaPod-App you will see what I mean. The pictures and diagrams will show up and change after a certain time in the podcast(-player) while it is running like in a presentation.

In this attached screenshot you can see one of the picture showing up. Later/Before and in other chapters they will change.

Would be great if the podcast will show up in Nextcloud News like in this AntennaPod Screenshot.

Here a screenshot for comparison how it shows up in the Nextcloud-News app: Screenshot_20220202-140307_News

@Grotax Is there a way to receive additional tags in the feed? Just looked into it the feed mentioned above but I can't seem to find a way to access the psc:chapters (https://podlove.org/simple-chapters/). And extracting the chapters from the m4a file doesn't seem possible as it is a proprietary implementation by apple..

@egabosh I'm not sure where AntennaPod is getting their images from.. but I don't see specific images for each chapter anywhere in the XML feed 🤔

Grotax commented 2 years ago

Hi there, no that is not possible.

As far as I know feed-io has a way to access non standard elements of feeds an items, maybe news could fetch them this way. But that would need to be implemented and stored in the DB currently that is not done, we only extract stuff like content and title.

As a long term antennapod user myself I think that the images come from the audio file. In previous versions of antennapod every episode would just have the standard image of the feed, same like news has only one favicon or logo. Then they implemented the feature to check the audio file for thumbnails which allowed individual pictures per episode.

I think it would be cool if news had better support for podcasts but at the moment it doesn't and it is probably a lot of work.

@David-Development I downloaded the m4a file and looked with ffmpeg/ffprobe in it. I can see only chapters but no pictures but anyway it is possible to access proprietary m4a files with OpenSource tools. :-)

For me it looks like the pictures are coming from somewhere else (not from the m4a). Maybe the code from AntennaPod (https://github.com/AntennaPod/AntennaPod) helps?

David-Development commented 2 years ago

@Grotax @egabosh Thank you for the information and the test with ffmpeg/ffprobe. I'm currently a little down under with work so I'm not sure when I'll have time to look into this as it is probably a reasonable amount of work. It definitely sounds like a great feature and if ffmpeg is able to extract the chapters that would be a great start as I always had that in mind for the app with the sliding panel in the app. So if anyone wants to start a MR already, I can support with feedback.
