[QUESTION] Struggling with KVS streams on iOS about amazon-kinesis-video-streams-producer-sdk-cpp

[djhanove]

A workaround I found was to increase the number of frames between keyframes. It seems iOS likes a longer fragment length
Can modify with the key-int-max param in your pipeline

HI @djhanove, thanks for sharing. Increasing the number of frames between keyframes will increase the fragment duration.

See the documentation for more information and troubleshooting tips: https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/troubleshooting.html#troubleshooting-hls

Hi @djhanove, can you please provide some more details as to how HLS playback is failing (are there any errors, is the HLS URL fetching successful, video player logs if possible), and what is the GetHLSStreamingSessionURL command properties are for the streams?

[djhanove]

Hi there,
The HLS URL is fetched successfully and playback tries to start but then results in the following black image.

I am using the baseline h-264 profile which is read correctly in the kinesis media player. No issues on android or web with the same pipeline.

The GetHLSStreamingSessionURL is configured below:

export async function GET(request: NextRequest, { params }: { params: { device_id: string } }) {
  const deviceId = params.device_id;
  const { searchParams } = new URL(request.url);
  const livestreamMode = searchParams.get("mode");
  const streamName = `xxxxxxx_${deviceId}_${livestreamMode === "thermal" ? "thermal" : "rgb"}`;

  try {
    const result = await new Promise((resolve, reject) => {
      kvClient.getDataEndpoint(
        {
          StreamName: streamName,
          APIName: "GET_HLS_STREAMING_SESSION_URL",
        },
        (err, data) => {
          if (err) {
            reject(err);
          }

          const kvArchived = new AWS.KinesisVideoArchivedMedia({
            endpoint: data.DataEndpoint,
          });

          kvArchived.getHLSStreamingSessionURL(
            {
              StreamName: streamName,
              PlaybackMode: "LIVE",
            },
            (err, data) => {
              if (err || !data?.HLSStreamingSessionURL) {
                reject(err);
              } else {
                resolve(data.HLSStreamingSessionURL);
              }
            },
          );
        },
      );
    });

    return NextResponse.json({ url: result });
  } catch (e) {
    console.log("ERROR SERVER", e);
    return NextResponse.json({ error: e.message }, { status: 400 });
  }
}

Can you please include what you were able to try from the above linked trouble shooting guide, and do you have any success using DASH instead of HLS on ios?
