Run AudioPlayer with url where Status Code 301

Viktor_Kravchuk · August 22, 2025, 2:54pm

I use import { AudioPlayer } from ‘@amzn**/react-native-w3cmedia’;**

Some audio URLs return a 301 Moved Permanently status. After the redirect, the correct .mp3 file loads with a 206 Partial Content status. However, audio loading is very slow, and after loading, my application runs sluggishly and sometimes crashes. Do you think the redirect could be causing memory leaks?

My code for init player

import { AudioPlayer } from '@amzn/react-native-w3cmedia';

//////

  const preBufferAudio = useCallback(
    async (src: string) => {
      if (audioRef?.current == null) {
        audioRef.current = new AudioPlayer();
      }

      try {
        await audioRef?.current.initialize();
        audioRef.current.src = src;
        audioRef.current.autoplay = true;
        audioRef.current.load();

      } catch (error) {
        dispatch(
          errorAction({
            level: ErrorLevel.SILENT,
            type: ErrorType.GENERAL,
            message: (error as Error).message,
          }),
        );
      }
    },
    [audioSrc, dispatch],
  );

  useEffect(() => {
    const initAudio = async () => {
     if (audioSrc) await preBufferAudio(audioSrc);
    };

    initAudio();
  }, [audioSrc]);

I tried launch vega-audio-sample and use link with long audio https://ia801004.us.archive.org/18/items/iliadsofhomer_2510_librivox/iliad_30_homer_64kb.mp3 (57 min it’s without redirecting).

I can see long loading before start. @Amz_Rsk Could you help me - How can I start playing immediately like in browser?

Vitalii_Rurenko · November 11, 2025, 9:24am

hello @Amz_Rsk

I just wanted to highlight that this issue has now become a release blocker for one of our customers.
It would be greatly appreciated if you could suggest a possible way to fix it.

Adding @jogashu for visibility — really hoping to get your support on this.

Thanks in advance,

Hi @Vitalii_Rurenko , @Viktor_Kravchuk ,

Thanks for sharing more details.
I have escalated this to our team to check on.

Rohit

Amz_Rsk · November 13, 2025, 6:20am

Hi @Viktor_Kravchuk ,

The sample vpkg file you shared seems to be corrupt. Our team was not able to use it.
Also, the team tried changing the content for “Rise UP” with the attached URL in sample audio app and the audio start in ~ 2 seconds.

Sharing some logs from our reproduction:
sampleaudiologs.txt (609.6 KB)

Could you please share your correct vpkg and logs over direct message to me (do not share vpkg here) please for our team to investigate and reproduce?

Thanks,
Rohit

Viktor_Kravchuk · November 14, 2025, 9:48am

Hello @Amz_Rsk I have sent vpkg file and video recording that and video recording when audio started after 1 minute waityng, on direct message.

Vitalii_Rurenko · November 18, 2025, 9:14am

Hi @Amz_Rsk do you think we can have some solutions based on the vpkg sent by @Viktor_Kravchuk .

Amz_Rsk · November 18, 2025, 9:41am

Hi @Viktor_Kravchuk /@Vitalii_Rurenko ,

Thank you for sharing the details.
I have already forwarded the video recording, vpkg to our team to reproduce and investigate.
Will update you once we here back from them.

Thanks,
Rohit
