  • Annual Release of External-Videos plugin – we’ve hit v1.0

    13 janvier 2017, par silvia

    This is the annual release of my external-videos wordpress plugin and with the help of Andrew Nimmolo I’m proud to annouce we’ve reached version 1.0 !

    So yes, my external-videos wordpress plugin is now roughly 7 years old, who would have thought ! During the year, I don’t get the luxury of spending time on maintaining this open source love child of mine, but at Christmas, my bad conscience catches up with me – every year ! I then spend some time going through bug reports, upgrading the plugin to the latest wordpress version, upgrading to the latest video site APIs, testing functionality and of course making a new release.

    This year has been quite special. The power of open source has kicked in and a new developer took an interest in external-videos. Andrew Nimmolo submitted patches over all of 2016. He decided to bring the external-videos plugin into the new decade with a huge update to the layout of the settings pages, general improvements, and an all-round update of all the video site APIs which included removing their overly complex SDKs and going straight for the REST APIs.

    Therefore, I’m very proud to be able to release version 1.0 today. Thanks, Andrew !

    Enjoy – and I look forward to many more contributions – have a Happy 2017 !

    —

    NOTE : If you’re upgrading from an older version, you might need to remove and re-add your social video sites because the API details have changed a bit. Also, we noticed that there were layout issues on WordPress 4.3.7, so try and make sure your WordPress version is up to date.

  • How to specify streams by pid with ffmpeg, If the value of pid is duplicated ?

    22 novembre 2019, par Bo Wang

    I have a nice m2ts file and I would like to demux specific audio streams from it. Of important, this specification is needed to use PID as identifier.
    The exemplified m2ts file has 7 audio streams, which is detected by eac3to and shown below

    eac3to.exe F:\xxx 1)
    
M2TS, 1 video track, 7 audio tracks, 5 subtitle tracks, 1:40:03
    
1: Chapters, 34 chapters
    
2: h265/HEVC, 2160p24 /1.001 (16:9), 10 bits
    
3: TrueHD/AC3 (Atmos), English, 7.1 channels, 48kHz, dialnorm: -28dB
    
   (embedded: AC3, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB)
    
4: E-AC3, English, 7.1 channels, 1024kbps, 48kHz, dialnorm: -28dB
    
   (core: AC3, 5.1 channels, 576kbps, 48kHz, dialnorm: -28dB)
    
5: AC3, English, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB
    
6: AC3, English, 2.0 channels, 320kbps, 48kHz, dialnorm: -27dB
    
7: AC3, English, 2.0 channels, 320kbps, 48kHz, dialnorm: -27dB
    
8: AC3, Chinese, 2.0 channels, 448kbps, 48kHz
    
9: AC3, Chinese, 5.1 channels, 384kbps, 48kHz, 300ms
    
10: Subtitle (PGS), English
    
11: Subtitle (PGS), Chinese
    
12: Subtitle (PGS), Chinese

14: Subtitle (PGS), Chinese

    However, if I run
    ffmpeg.exe -hide_banner -i "F:\xxx\BDMV\STREAM\00055.m2ts", ffmpeg shows an additional audio stream as it recognizes the embedded 5.1 AC3 stream inside the 7.1 TrueHD audio stream, as independent :
