Hi, I'm working with Fairplay DRM.. I'm not quite sure how to send a reproducible example

[rohankm]

video with lesser duration plays fine but not with more duration(30 mins +). The player is stuck buffering

[rohankm]

the issue still persists in the latest version

[rohankm]

@freeboub the issue still exists for the DRM videos on ios... videos without DRM work fine.

[freeboub]

Not sure how we can help here ...
Do you have issues in xcode logs ? Did you try to record a charles trace to ensure network communications work fine ?

[rohankm]

@freeboub the network communication is fine and there are no xcode logs.. it's just the video buffers forever. {"isBuffering": true, "target": 6819}

Im currently testing with ios 14.8

[rohankm]

@freeboub I tested on a newer device with the latest ios but the problem still exists... probably can we connect on discord and I will share the DRM content so that you can check it from your end also.

[rohankm]

adding maxBitRate={3000000} the video loads perfectly

[KrzysztofMoch]

So probably not an library issue ?

So probably not an library issue ?

I really don't understand what exactly is the issue.. or how do I even debug the issue

[KrzysztofMoch]

Maybe I will add to docs (in debug section) to try set maxBitRate in such case - let's close this as I see that this worked for you

[rohankm]

setting maxBitRate={0} also works fine

[rohankm]

@freeboub @KrzysztofMoch reopening the issue as setting maxBitRate just lowers the video quality. Also, i tested with expo-video and it works fine... I don't know what the issue is with react-native-video with DRM videos. Is there any steps to debug this buffering issue?

[Meet-Kapadiya]

Same problem still persists in 6.2.0, You can check by logging "isBuffering", It never returns false

[Meet-Kapadiya]

 useEffect(() => {
    if (Platform.OS === 'ios' && loading) {
      setTimeout(() => {
        setLoading(false);
      }, 2500);
    }
  }, [loading]);

For temporary workaround you can do this

[rohankm]

We cannot use this hack in production... The bug should be fixed

[freeboub]

If you want to investigate here are some inputs:
handlePlaybackBufferKeyEmpty and handlePlaybackLikelyToKeepUp are good starting points.
relevant documentation is here: https://developer.apple.com/documentation/avfoundation/avplayeritem/1390348-isplaybacklikelytokeepup

react-native-video+6.1.2.patch

I made the patch, it works fine, but at the beginning when I start playing the video, the buffering takes time to return false is proportional to the length of the video.

[rohankm]

@Meet-Kapadiya are you testing with drm videos or normal?

[Meet-Kapadiya]

HLS streams

[Meet-Kapadiya]

react-native-video+6.1.2.patch

I made the patch, it works fine, but at the beginning when I start playing the video, the buffering takes time to return false is proportional to the length of the video.

To solve this you can set

• preferredForwardBufferDuration={15} (In Seconds)
• Default value is 0, So player will choose an appropriate level of buffering

It seems that it only happens with HLS/m3u8 format, please take a look at that @freeboub
