1. Summary

We came across an issue in our internal Shaka Player wrapper and discovered that originalVideoId is missing from Shaka’s variantTrack on some HLS streams. We identified the fix in a later version of Shaka v4.13.2 and would like to have this patched in Amazon’s Shaka fork.

7. Example Code Snippet / Screenshots / Screengrabs

Include any relevant code or component setup in React Native that can help reproduce the bug.

Custom code that presented the missing originalVideoId. We were finding duplicate audio tracks in our filter, where we expected one.

const getShakaAudioTracks = () => {
            const variants = player.getVariantTracks();
            const activeVariant = player.getVariantTracks().find(isActive)

            return variants.filter((variant) =>
                variant.originalVideoId === activeVariant.originalVideoId && variant.audioCodec);
        }

        const logAudioTracks = () => {
            const audioTracks = getShakaAudioTracks();
            console.log(audioTracks);
        }

        logAudioTracks();
