• mov atom not found when merging images on debian 9

  27 avril 2018, par robert tamunoemi

  Am extracting images from videos which I use in creating slideshows. Creating slideshows from the extracted images only works fine.However, when I add an image from my computer to the sets of extracted images, I get this error

• ffmpeg not available on Oracle Linux 9 update 3 [closed]

  19 janvier 2024, par Red Cricket

  I cannot figure out how to install ffmpeg on a Oracle Linux 9 update 3 (RHCK).

  


  [root@snc-ol93-rhck ~]# dnf install ffmpeg-free

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)


  


  Turns out I needed to install the repo like so in my ansible playbook

  


  dnf install https://mirrors.rpmfusion.org/free/el/rpmfusion-free-release-9.noarch.rpm


  


• libavformat : add RCWT closed caption muxex

  libavformat : add RCWT closed caption muxex
  Signed-off-by : Marth64 <marth64@proxyid.net>
  Raw Captions With Time (RCWT) is a format native to ccextractor, a commonly
  
  used open source tool for processing 608/708 closed caption (CC) sources.
  
  It can be used to archive the original, raw CC bitstream and to produce
  
  a source file file for later CC processing or conversion. As a result,
  
  it also allows for interopability with ccextractor for processing CC data
  
  extracted via ffmpeg. The format is simple to parse and can be used
  
  to retain all lines and variants of CC.
  A free specification of RCWT can be found here :
  
  https://github.com/CCExtractor/ccextractor/blob/master/docs/BINARY_FILE_FORMAT.TXT
  
  This muxer implements the specification as of 01/05/2024, which has
  
  been stable and unchanged for 10 years as of this writing.
  This muxer will have some nuances from the way that ccextractor muxes RCWT.
  
  No compatibility issues when processing the output with ccextractor
  
  have been observed as a result of this so far, but mileage may vary
  
  and outputs will not be a bit-exact match.
  Specifically, the differences are :
  
  (1)  This muxer will identify as "FF" as the writing program identifier, so
  
  as to be honest about the output's origin.
  (2)  ffmpeg's MPEG-1/2, H264, HEVC, etc. decoders extract closed captioning
  
  data differently than ccextractor from embedded SEI/user data.
  
  For example, DVD captioning bytes will be translated to ATSC A53 format.
  
  This allows ffmpeg to handle 608/708 in a consistant way downstream.
  
  This is a lossless conversion and the meaningful data is retained.
  (3)  This muxer will not alter the extracted data except to remove invalid
  
  packets in between valid CC blocks. On the other hand, ccextractor
  
  will by default remove mid-stream padding, and add padding at the end
  
  of the stream (in order to convey the end time of the source video).
