  • confused about lhls in ffmpeg

    27 décembre 2020, par JohnL

    I am more than a little confused about trying to use the experimental lhls option in ffmpeg.

    


    I have built ffmpeg from source (which takes a while), and currently have version 4.1.6 running.

    


    Reading other threads here, and the ffmpeg docs, it appears that the lhls option is available only in the Dash muxer.

    


    I gravitated to HLS because of its support in Apple devices, and I thought that lhls was related (and Apple was drafting the spec).

    


    Then there is the comment in the ffmpeg docs that states that the hls.js folks are working on supporting lhls in their library, which I also use to support browsers like Chrome.

    


    Should I be using dash instead of hls for my prototype ? I want to try and get very low latency for a construction inspection app I am considering building. Right now, the latency I am seeing is 10-15 seconds.

    


    Any insights would be appreciated. TIA

    


    See my comment below. I have many of the dash format flags working, but can't get -lhls to work. Here are some of the build flags used :

  • Getting Audio and Video from Steams

    16 novembre 2018, par anon

    I’m trying to download a video from BritBox. After observing my network packets, it seems they stream the video in .m4s fragments.

    I’ve looked into InviDownloader, but can’t seem to get it to pick up all the pieces. I don’t think I’m giving it the correct URL but can’t find the correct one either. I’ve taken a look at this question but I think it requires a specific URL as well, which I can’t seem to find.

    Most fragments (if not all) have a .dash extension, so I tried to get it working with GPAC’s dashcast but couldn’t get that working either. I’ve also seen Handbrake being thrown around but haven’t tried it.

    After trying tons of browser extensions, I found one that can correctly piece together the .m4s files, at least to an extent. If you carefully refresh the extension when new packets are downloaded, you can download a result of the entire .m4s.

    Then, using youtube-dl and ffmpeg you can convert it to an mp4 file. However, this has no audio.

    I’m not too savvy when it comes to videos or streaming. Is there an easy way to download these videos to an mp4 format with audio ?

  • mov : Support default-base-is-moof.

    1er juillet 2014, par Yusuke Nakamura
    mov : Support default-base-is-moof.

    default-base-is-moof shall be set to track fragments compatible with DASH
    
Media Segments. So, this is a fundamental support for ISOBMFF ver. DASH.
    
This is meaningful only when base-data-offset-present is absent and two or
    
more track fragments are present in a movie fragment.
