    Hello Martin, thanks for the info! your answers are very valuable and helpful!

    questions:

    1. how do you test transcoded streams on Android/iPhone? do you use some website or applications or simply direct URL to m3u8 in browser?
    2. do you have any roadmap to update HLS.js in FV Player? will it be upgraded only for version 8 or 7 also?
    3. do you have demo page, where it is possible to test concrete video URL in FV Player? AFAIS all URLs in demos are hardcoded and my attempts to inject own URL into player in HTML are failed

    thanks!

    Hello Martin, thanks for the info.

    i added is-splash-class here: https://jsfiddle.net/qr5pscLd/ .
    results.
    a) it seems video doesn’t preload
    b) sticky-issue doesn’t exist
    c) but splash also doesn’t rendered. AFAIU in data-item-attribute exists splash-property with URL to it. on demo pages it works, but on jsfiddle – not.

    > We will fix this in FV Player too – if video preloads, it should not affect sticky player behavior.
    happy waiting. do you have some special roadmap-page, releases-page to subscribe?

    thanks!

    Martin, i use FV Player separate from wordpress and test its functionality by reading docs and examples)

    > wp-admin -> FV Player -> Settings -> Autoplay and preloading. Are you using the “Video Preload” setting
    AFAIU this setting should in some way be injected into fv_flowplayer_conf?

    thanks!

    Hello, Martin

    continue reading articles.. due to this answer: https://repost.aws/questions/QUAUznNk7VT3mosH8v9McRDw/mediaconvert-hevc-forcing-hvc1-tag-in-an-hls-output-group it seems CMAF is the unique possible solution to play HLS on iPhone and other places.

    today transcoded video as CMAF:
    hev1.1.6.L150.B0,mp4a.40.2
    hvc1.1.6.L150.B0,mp4a.40.2 (this result on attachments: https://drive.google.com/file/d/1MvEOr9O8aHg_cj5usF70-QrsAyBXc38Q/view?usp=sharing)

    result:
    macOS chrome https://hlsjs.video-dev.org/demo – success
    macOS chrome https://developer-tools.jwplayer.com/stream-tester – success
    macOS safari direct m3u8 – success
    ipadOS safari direct m3u8 – success
    FV Player 7/8 – unable to play

    questions:

    1. why do you think FV Player 7/8 unable to play CMAF? lower version or hls.js or something else?
    2. how do you test transcoded streams on Android/iPhone? do you use some website or applications?
    3. how do you think WHY MediaConvert has possibility to transcode videos to TS-segments in HLS using H.265 if this result can’t be played (confirmed by my and your tests) on iPhone platform, strictly for which HLS was created?

    thanks!

    Hello, Martin, thanks for the fast response! :)

    i changed codec level to 4.0, 4.1. in both cases MediaConvert returned error:
    1040 – Error initializing encoder for video target [1] [initialization failed: Invalid level specified for the selected resolution.]

    on level 5.0 it processed, but with the same result as on 5.1 – no picture.

    so it is really interesting which parameters to use in MediaConvert to get applicable HLS-result compatible +/- with different OS/browsers.

    MediaConvert doesn’t have system presets:
    a) for HLS using H.264 for resolutions higher than Full HD (but it should be compatible – https://docs.aws.amazon.com/mediaconvert/latest/ug/supported-output-resolution-maximums-by-codec.html)
    b) for HLS using H.265

    their support answered to me like: you can create own preset by using parameters/values from other Generic-presets or using https://developer.apple.com/documentation/http-live-streaming/hls-authoring-specification-for-apple-devices.

    also i checked fast your suggested playlist https://bitmovin-a.akamaihd.net/content/dataset/multi-codec/hevc/stream_fmp4.m3u8.
    AFAIU it is CMAF, because it has not ts-segments, but m4s. this container i didn’t use before, because i trusted that HLS – is completely enough for my needs. and internet AFAIR said that HLS is wider supported.
    but in general HLS should work nowadays? how iPhone 16 unable to play it? :) if it unable – then what can?

    Hi Martin, i am trying to test H.265 codec on FV Flowplayer Video Player.

    steps:

    1. i took 4K video
    2. transcoded it using MediaConvert using container “MPEG-2 Transport Stream for Apple Adaptive” (which we also use for HLS codec H.264 for lower resolutions <= Full HD)
    3. i tested resulted HLS video using:
      desktop MacOS VLC – success
      hls.js demo page (https://hlsjs.video-dev.org/demo/) – success
      FV Flowplayer Video Player – fail (player downloads ts-file, progressbar ticks seconds, but i don’t see picture)

    questions:

    1. what is the possible issue and how to debug the reason?
    2. does FV Flowplayer Video Player compatible with MediaConvert “MPEG-2 Transport Stream for Apple Adaptive” container to create HLS? we use it for different resolutions without issues, but now want to try with 4K
    3. maybe you have other suggestions (from your experince) about best MediaConvert-presets/containers/… for HLS, which will work for FV Flowplayer Video Player?
    4. does FV Player 8 has better compatibility with H.265?

    P.S. job.json, raw and resulted video files in the attachments: https://drive.google.com/file/d/1uj4Kw-_OgAyj4UGwJGS1eo4BK9nqHlO0/view?usp=sharing

    Thanks!
