  • How can I determine the CODECS value for a m3u8 playlist ?

    28 août 2023, par arrr_matey

    I am creating a master m3u8 file to allow adaptive streaming of two streaming videos. Both have the readable codec name MPEG-4 AVC (part 10) (avc1)

    


    How can I translate this into the CODECS value that should appear in my master m3u8 playlist file, as in this example :

    


    #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1755600,CODECS="avc1.42001f,mp4a.40.2",RESOLUTION=354x240

    


    How do I get the value to replace avc1.42001f,mp4a.40.2

    


    Apple's specs say "Valid format identifiers are those in the ISO file format name space defined by RFC 6381 [RFC6381]" but I have no idea how to read the RFC 6381 documentation.

    16 février 2021, par Muath

    This image displays each offset and the role of that offset in mp4 file.

    


    enter image description here

    


    And this is MP4 file viewed in Hex-Editor :

    


    enter image description here

    


    When cutting (as an example) first 60 seconds of that video or doing any cutting process, How can I know which offsets has been changed ?

    


  • Is there a way to use ffmpeg to determine the encoding of a file before transcoding ?

    5 mai 2022, par Bill Noble

    I am planning to use ffmpeg to ensure all video files uploaded to my website are encoded as mp4 h264.

    



    Rather than automatically processing every file I would like to minimise the processing overhead by only processing those files that are not already mp4 h264. Is there an easy way to do this either with ffmpeg or with another command line utility ?
