• why doesn't avformat_find_stream_info return with mp3 files

  18 avril 2014, par user1379811

  I have built and am using the latest build of lame, x264 and ffmpeg in my c++ project.

  If I call avformat_find_stream_info with an mp3 file it doesn't return but if I use a .mp4 file instead avformat_find_stream_info returns fine.

  I have tried different mp3 files and all give the same problem. They all seem to start with id3 if that has any effect ?

  I can't read more than 1 frame of data from the mp3 file with avformat_find_stream_info commented out so I'm thinking it's important.

  Can anyone offer a reason for avformat_find_stream_info not returning ? There seemed to be a patch for an endless loop but it seems thats already in utils.c.

  I have also tried to read and decode the mp3 files directly using fread but then I get a mp3 missing header error.

  Thanks.

• 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.

• FFmpeg : Continuously download X minutes video from livestream ?

  16 février 2017, par Dorin Pleava

  I want to download X minutes from a livestream continuously and overwrite the same file, meaning the file will always have the latest X minutes from the livestream.

  Is there a way without calling the following command over and over again in a batch file ? Something that runs continuously from FFMPEG ?
