App freezes when playing OPUS

[stonerl]

With the latest version (1.2.1) I do have some playback problems which result in an error-message. This happens out of thin air when podcasts from opus feed are played.

Especially when using chapter-marks or fast-forward to jump to a specific part in the podcast.

I observed this with the following podcast:

http://feeds.feedburner.com/freakshow/opus
http://www.staatsbuergerkunde-podcast.de/feed/opus-rss/

To use AntennaPod again I have to force stop it.

I'm using CM12.1 Nightlies on an OnePlus One.

Google lead me to https://code.google.com/p/android/issues/detail?id=80729 and https://code.google.com/p/android/issues/detail?id=158490

Looks like OPUS is still pretty experimental on Lollipop.
On the other hand, OGG has worked pretty good for me in the past. OGG files seem to be only slightly larger, so I would recommend sticking with them.

I cannot confirm this issue. I've listened to several Opus feeds with Antennapod since it is possible (i.e. since I've upgraded to Android 6) and haven't encountered such playback issues.

I've upgraded a Nexus 5 device to Android 6 since it was released. I also use Antennapod Opus playback on a Nexus 5x - didn't notice any playback issues there so far, too.

Opus feeds I've subscribed to are for example feeds from the metaebene.me (e.g. Freakshow, Logbuch Netzpolitik, ...) and Binärgewitter.

Well then it seems Android 6 got opus support. Will test this.

[stonerl]

Close as fixed

According to Google [1], OPUS has been introduced in Lollipop.

OK, let me rephrase it to: Android 6 finally got proper opus support. :-)

[stonerl]

Just an additional note; the problem seems to be CyanogenMod not Android nor AntennaPod. I installed today's cm nightly and opus playback got butchered again.

@stonerl Did you try this with the same Opus files or different ones? It might just be that the decoder is not able to decode files with particular features.
Android only seems to be able to play Opus when it is encapsulated in Matroska (mkv), but the recommended container for .opus is the Ogg container [1].

I tried the same file. Opus file in ogg-container. The file worked yesterday but today after the upgrade the file does not playback anymore. It is just sizzling.

Alright. Let's settle on: CyanogenMod's fault. AGAIN... :>
[and people seem to wonder why one of my first questions always is whether or not they are using a custom rom...]
