MediaConvert HLS manifest error
Hey there, I'm despairing... I want to create a MediaConvert job with an HLS output group but without any video input, two audioselectors. My current manifest looks like this: ``` #EXTM3U #EXT-X-VERSION:4 #EXT-X-INDEPENDENT-SEGMENTS #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="program_audio",LANGUAGE="eng",NAME="BEsAsDes",AUTOSELECT=YES,DEFAULT=YES,URI="indexB-Es-As-Des.m3u8" #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="program_audio",LANGUAGE="eng",NAME="ADGC",AUTOSELECT=YES,DEFAULT=YES,URI="indexA-D-G-C.m3u8" ``` It isn't working on any player I'm getting errors like manifest invalid. Any help is much appreciated!
MediaConvert HLS subtitles off by default
According to https://docs.aws.amazon.com/mediaconvert/latest/ug/ttml-and-webvtt-output-captions.html The captions track that you specify first in your job is signaled as the default track in the HLS manifest. We're seeing our English subtitles automatically enabled on playback. In the HLS manifest, I see `#EXT-X-MEDIA:TYPE=SUBTITLES,GROUP-ID="subs",NAME="English",DEFAULT=YES...` but manually changing that to `#EXT-X-MEDIA:TYPE=SUBTITLES,GROUP-ID="subs",NAME="English",DEFAULT=NO...` elicits the desired playback experience with subtitles turned off by default. I'm trying to find some way to achieve this through MediaConvert, rather than at the player level or as some post-processing job that modifies the manifest. Is there such a capability?
AWS Elemental MediaConvert - Can you force a transcoded file to have a Metadata tag for 1-13-1 color space?
I need to be able to make H264 proxy files that have the metadata tag and color space of 1-13-1. I can see options in MediaConvert to force the color space to 709, but the metadata tag for 1-13-1 isn't there.
AWS MediaConvert - Job for multiple audio-only stream
Hey there, doesn't matter which settings I try, I just can't get it work. I have several MP3 audio selectors for input and trying to get them into one HLS output group as 1:1 outputs (audio-only). What I want is an audio-only stream where I can switch between the tracks/languages. I already made this running with video but it's not working if I use the same settings and just delete the "video" parts of the job. So what I'm doing wrong?
Mediaconvert not adding some CEA-608 captions
I'm using mediaconvert to embed CEA-608 captions into a .MP4 file. It mainly works - the output file contains most of the captions - but occasionally it drops a caption and doesn't embed it. Does anybody have any idea why, or how to troubleshoot this? All the captions are of under 32 character line lengths and so on. Thanks!
Small Scale VOD Streaming - Am I looking in the right place?
Hi, I am learning AWS as I go... I work for a small company that would like to sell video subscriptions. I am looking into MediaConvert, MediaPackage and MediaStore with the plan to embed the output on our website in a secure way (users unable to download). If I had to guess, I would say we have about 20 hours of videos and would stream to about 30 users a month. Am I looking in the right spot or is this overkill?
Elemental MediaPackage MPD or HLS playback from middle
I have a requirement to play video from a position from where i left (store the position where I left) and continue to play from last position where i left. I tried multiple ways but non of them worked. Please someone guide me. I am having HLS and MPD url and using using elemental MediaPackage with CloudFront to stream the video.
Dash-Outputs with QVBR always exhaust the maximum bit rate allowed
Hi, we are creating HLS- and DASH-Outputs via MediaConvert (1080p, 720p, 480p, 360p). While testing our transcoded playlists on [Bitmovin's test environment](https://bitmovin.com/demos/stream-test?format=dash&manifest=https%3A%2F%2Fbitmovin-a.akamaihd.net%2Fcontent%2FMI201109210084_1%2Fmpds%2Ff08e80da-bf1d-4e3d-8899-f0f6155f6efa.mpd), we noticed that our DASH content is always loaded with the bitrate which we set as the maximum value for QVBR (Single Pass HQ, no fine tuning). In contrary our HLS content is loaded with a variable bitrate which was considered suitable by MediaConverts rate control mode QVBR (so I think). Since our encoding settings for DASH and HLS are identical, we wonder if that behaviour is "correct". If someone could take a look at this issue, it would be much appreciated.

MediaConvert - Arabic DVB Subtitle not rendering properly
Hello. I am using MediaConvert to create MPEGTS Streams that contain English, Arabic, and Chinese DVB Subtitles. My English and Chinese Subtitles render properly, but my Arabic only shows boxes as opposed to the actual characters I have tried sourcing from both a VTT and IMSC Subtitle, but both yield the same results. I have my "Language" on the output DVB also set for "Arabic". Lastly, I have tried multiple combinations of setting the "Font Script" and "Fallback Font" Nothing I do will render out Arabic Characters though. I am not sure what other settings I can tweak - or if this is a bug.
[MediaConvert] Job has stuck at 90%
Hey, I've been playing around the public Video On Demand stack available at https://github.com/aws-solutions/video-on-demand-on-aws. Successfully tested a few .mp4 video files, however ran into a really strange issue for a larger .mp4 video file (14GB). The MediaConvert Job is stuck in TRANSCODING status at 90% of progress and don't fully understand why. What I noticed is that the retry count increases. I don't know how to find attached logs for the job, is it even possible to review them? Any idea or suggestion how to discover the issue?
