Hi, we are currently working on the creation of a FAST-Channel via MediaTailor (based on HLS-content created via MediaConvert). Samsung-TV expects that the stream includes Ad-Markers: * Samsung requires frame-accurate ad markers (SCTE-35 supported) * Variant manifest should have SCTE HLS tags indicating ad insertion points I then added an ESAM-XML (with three ad breaks starting 10s, 20s and 30s) when creating HLS-Outputs (HEVC-Codec) via MediaConvert with the following settings: * Video Output Settings -> SCTE-35 source: "passtrough" * Apple HLS group settings -> Ad markers: "elemental (enabled)" The variant manifests provided by my [Main-Manifest](https://amogo-public.s3.sa-east-1.amazonaws.com/output/test/Por_um_Caixao_Cheio_de_Dolares_audioMatchVideoDuration_H265_ESAM_3xAdBreaks10s/snippet/hls/hls.m3u8) seem to properly include Ad-Markers: ``` ... #EXT-X-PLAYLIST-TYPE:VOD #EXTINF:6.000, hlsvideo_720_00001.ts #EXTINF:4.000, hlsvideo_720_00002.ts #EXT-X-CUE-OUT:0 #EXT-X-CUE-IN #EXTINF:2.000, hlsvideo_720_00003.ts #EXTINF:6.000, hlsvideo_720_00004.ts #EXTINF:2.000, hlsvideo_720_00005.ts #EXT-X-CUE-OUT:0 #EXT-X-CUE-IN ... ``` In the following I created a Channel via MediaTailor and added the previously described VOD-Source as a program and started the channel. When looking at fetched variant playlists, I can't find any EXT-X-CUEs (at the start of the Video with 5min duration): ``` #EXTM3U #EXT-X-VERSION:6 #EXT-X-TARGETDURATION:7 #EXT-X-MEDIA-SEQUENCE:0 #EXT-X-DISCONTINUITY-SEQUENCE:0 #EXT-X-DISCONTINUITY #EXT-X-PROGRAM-DATE-TIME:2022-04-11T19:28:52.452Z #EXTINF:6.0, https://amogo-public.s3.sa-east-1.amazonaws.com/output/test/Por_um_Caixao_Cheio_de_Dolares_audioMatchVideoDuration_H265_ESAM_3xAdBreaks10s/snippet/hls/hlsvideo_720_00001.ts #EXT-X-PROGRAM-DATE-TIME:2022-04-11T19:28:58.452Z #EXTINF:4.0, https://amogo-public.s3.sa-east-1.amazonaws.com/output/test/Por_um_Caixao_Cheio_de_Dolares_audioMatchVideoDuration_H265_ESAM_3xAdBreaks10s/snippet/hls/hlsvideo_720_00002.ts #EXT-X-PROGRAM-DATE-TIME:2022-04-11T19:29:02.452Z #EXTINF:2.0, https://amogo-public.s3.sa-east-1.amazonaws.com/output/test/Por_um_Caixao_Cheio_de_Dolares_audioMatchVideoDuration_H265_ESAM_3xAdBreaks10s/snippet/hls/hlsvideo_720_00003.ts #EXT-X-PROGRAM-DATE-TIME:2022-04-11T19:29:04.452Z #EXTINF:6.0, https://amogo-public.s3.sa-east-1.amazonaws.com/output/test/Por_um_Caixao_Cheio_de_Dolares_audioMatchVideoDuration_H265_ESAM_3xAdBreaks10s/snippet/hls/hlsvideo_720_00004.ts ... ``` Is my approach here correct for adding the Ad-Markers to our Live-Stream? Kind regards, Riva

Hi, we are currently testing MediaTailor in order to create a Live-Stream based on VOD material. The stream should be provided to Samsung-TV. After delivering a Test-Stream we received the following Feedback: * Variant manifest has absolute URLs which we don’t support. Please have it changed to reflect relative URLs instead When checking the manifest I can see absoute URLs in the form of ``` ... #EXTINF:5.995, https://amogo-public.s3.sa-east-1.amazonaws.com/output/samsung_channel/E_Deus_Disse_A_Caim_1080p/full_movie/hls/hlsaudio_20pt_00253.aac #EXT-X-PROGRAM-DATE-TIME:2022-04-11T12:37:49.485706Z #EXTINF:6.016, https://amogo-public.s3.sa-east-1.amazonaws.com/output/samsung_channel/E_Deus_Disse_A_Caim_1080p/full_movie/hls/hlsaudio_20pt_00254.aac #EXT-X-PROGRAM-DATE-TIME:2022-04-11T12:37:55.500706Z #EXTINF:5.995, ... ``` My question is, if it is possible to avoid these absolute URLs in order to support the Samsung-TV specification? Kind regards, Riva

As per https://docs.aws.amazon.com/mediatailor/latest/ug/ad-reporting-client-side.html 1. Need a player which can be programmed to poll the tracking URL Periodically 2. I am not aware of such players which can run Manifest as well as it can poll URL

1. Does MediaTailor supports replacing standard VAST Macros in case of Server Side Tracking ? 2. Standard VAST Macros - https://interactiveadvertisingbureau.github.io/vast/vast4macros/vast4-macros-latest.html#macro-spec-timestamp 3. If yes, how to configure it ? 4. If no, How to achieve MediaTailor replacing Standard VAST Macros present in Tracking URLS ? 5. Also [SERVERUA] macro will be useful 6.

Hi, I receive alerts for SEGMENT_DURATION_MISMATCH when adding a single program (Hls-Source with ABR 1080/720/576) to my Test-Channel. How can it be that there are mismatch alerts, when only a single program is provided? An example alert is displayed in following: `PROGRAM_ALERT The program test contained in this channel has the following alert: SEGMENT_DURATION_MISMATCH: MediaTailor encountered mismatched segment duration values across manifests in Segment-Duration-Test schedule. The mismatch is in source-group-2 between test's manifest https://amogo-public.s3.sa-east-1.amazonaws.com/output/test/samsung_channel/Por_um_Caixao_Cheio_de_Dolares_1080p_cbr_audio/full_movie/hls/hlsvideo_1080.m3u8 and test's manifest https://amogo-public.s3.sa-east-1.amazonaws.com/output/test/samsung_channel/Por_um_Caixao_Cheio_de_Dolares_1080p_cbr_audio/full_movie/hls/hlsvideo_1080.m3u8`

Hello MediaTailor is able to deliver preroll AND midroll in AUDIO HLS streams ? Thanks

Hello I am having issue while scheduling program with mediatailor. I have schedule a program (i.e Program A) for next week and now I am trying to schedule another program (i.e Program B) for this week but I am getting error. I am passing "Program A" as relative program for "Program B" and I am getting this error: *You tried to use [Program A] as a relative program in channel [abc-channel]. You can't use programs that are currently playing or scheduled to play soon. Choose a different relative program.*

I have a question regarding how the tracking events are fired at the server side (start, first quartile, midpoint, third quartile, and ad completion ). Namely, if i have a preroll with a duration of 10 seconds, i would expect that the midpoint event gets trigger at 5 second mark, and the completed event at 10 second mark. For example : start event is fired at 11:51:40, midpoint event at 11:51:45 and completed event at 11:51:50. What actually happens is, all tracking events are fired at the pretty much the same time, where the difference between the start and the completed events is maybe a second or two. For example : start event is fired at 11:51:40, midpoint event at 11:51:41 and completed event at 11:51:42. All of the available events are triggered, with no regards to how many seconds of the ad the user has actually watched. This does not provide correct tracking information. Am i missing something? Is this how server side tracking is supposed to work? Maybe initial video buffering is triggering all of this events at once? Any information you can provide is useful. Thanks in advance.

Hey gang. I'm playing around with Media Tailor, and I'm not able to get a very basic stream to work. Here's my source: ``` http://edge.theplatform-live-test.top.comcast.net/demo/superflaco/superstream/loopMaster.m3u8 ``` And here's my ad URL: ``` http://7baa3.v.fwmrm.net/ad/g/1?nw=506531&mode=live&prof=96749%3Aglobal-cocoa&caid=kwality_video&csid=ad_plethora&resp=vast2&pvrn=[avail.random]&vprn=[avail.random]&vdty=variable&vrdu=[session.avail_duration_secs];;slid=mid&tpcl=MIDROLL&ptgt=a&cpsq=[session.avail_duration_secs]&mind=[session.avail_duration_secs]&maxd=[session.avail_duration_secs] ``` but when I hit the delivery URL, I get: ``` HTTP/1.1 404 Not Found Access-Control-Allow-Origin: * Access-Control-Expose-Headers: x-amzn-RequestId,x-amzn-ErrorType,x-amzn-ErrorMessage,Date,x-amz-source Content-Encoding: gzip Date: Fri, 26 Jan 2018 20:20:01 GMT x-amzn-RequestId: 239afb79-8fee-4494-b644-f25867b8f786 Content-Length: 46 Connection: Keep-alive <UnknownOperationException/> ``` Not the most helpful error message. Can any Media Tailor smartypants suggest what I'm doing wrong here? Thanks in advance.
