• Official RealVideo Specifications

  29 July 2010, by Multimedia Mike — General

  A little birdie tipped me off to a publicly-accessible URL on the Helix community site (does anyone actually use Helix?) that contains a bunch of specifications for RealVideo 8 and 9. I have been sifting through the documents to see exactly what they contain as the different files seem to be higher revisions of the same documents. Here is the title, date, and version of each PDF document:

  • RNDecoderPerformanceARM.pdf: Decoder Performance on StrongARM and XScale; May 12, 2003; Version 1.1
  • rv89_decoder_summary.pdf: RealVideo 8/9 Combo Decoder Summary; October 23, 2002; Version 1.0
  • rv9_dec_external_spec_v14.pdf: RealVideo 9 External Specification; November 7, 2003; Version 1.4
  • rv8_dec_external_spec_v20.pdf: RealVideo 8 External Specification; September 19, 2002; Version 2.0
  • RV8DecoderExternalSpecificationv201.pdf: RealVideo 8 External Specification; October 20, 2006; Version 2.01
  • RV8DecoderExternalSpecificationv202.pdf: RealVideo 8 External Specification; April 23, 2007; Version 2.02
  • RV8DecoderExternalSpecificationv203.pdf: RealVideo 8 External Specification; July 20, 2007; Version 2.03
  • RV8DecoderExternalSpecificationv21.pdf: RealVideo 8 External Specification; September 11, 2007; Version 2.1
  • RV9DecoderExternalSpecificationv15.pdf; RealVideo 9 External Specification; January 26, 2002; Version 1.5
  • RV9DecoderExternalSpecificationv16.pdf; RealVideo 9 External Specification; August 17, 2005; Version 1.6
  • RV9DecoderExternalSpecificationv18.pdf; RealVideo 9 External Specification; September 11, 2007; Version 1.8

  Additionally, there is an Excel spreadsheet entitled realvideo-faq.xls that appears to contain some general tech support advice for using Real’s official code. There are also 3 ZIP archives which contain profiling information about the official source code (post processing and entropy decoding top the charts which is no big surprise).

  I guess the latest version of each document (the ones dated September 11, 2007) are worth mirroring. Unfortunately, those latest document versions use a terrible font.

• how to ignore or fix false 'unmet dependencies' error?

  31 August 2014, by yy502

  OS: LMDE 201403

  I previously installed OpenShot (a video editing software), which depends on libmlt6, and libmlt6 depends on ffmpeg. The chain of dependencies auto-installed just fine.

  Today I compiled and installed the latest ffmpeg v2.3.3 and apt-get starts to complain:

  You might want to run 'apt-get -f install' to correct these:
  
  The following packages have unmet dependencies:
  
   libmlt6 : Depends: ffmpeg (>= 5:0.6.2~) but 2.3.3-1 is to be installed
  
  E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

  Well, I’m sure my compiled version of ffmpeg is newer than whatever version libmlt6 requires, but the package manager does not seem to understand the new version number. How can I ignore or fix false ’unmet dependencies’ error, please?

  Thanks for your time!

  Edit:

  Executing apt-get -f install would install the ffmpeg from repository to /usr/bin/ and uninstall/overwrite my compiled version of ffmpeg in /usr/local/bin/... not really the solution I’m after...

  Edit2:

  the auto fix of apt-get will remove my compiled version of ffmpeg as prompted below:

  sudo apt-get install -f

• fate: Remove duplicate wmv8_x8intra.wmv test

  8 May 2016, by Michael Niedermayer

  fate: Remove duplicate wmv8_x8intra.wmv test
  Also temporary enable the test so we get updated fate failure statistics
  Note, this does not work on all platforms, it fails on MIPS
  
  and ml archives indicate it failed on x86 openbsd with some compilers as well
