  • Official RealVideo Specifications

    29 juillet 2010, par 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.

  • bash loop through list of file paths - characters get removed when sending to ffmpeg [duplicate]

    9 octobre 2018, par Brad Johnson

    This question already has an answer here :

    I have a text file that contains a list of paths to flac files I want to convert to wav. Here is a small section of it :

    /mnt/nfs/Music/Rob D/1995 - Clubbed To Death/Rob D - 02 - Clubbed To Death _Kurayamino Variation_.flac
    
/mnt/nfs/Music/Blonde Redhead/2000 - Melody of Certain Damaged Lemons/11 - For the Damaged Coda.flac
    
/mnt/nfs/Music/I Monster/2001 - Daydream In Blue/01 - Daydream In Blue.flac
    
/mnt/nfs/Music/Moby/2002 - Extreme Ways/01 - Extreme Ways.flac
    
/mnt/nfs/Music/RJD2/2002 - Deadringer/01 - The Horror.flac
    
/mnt/nfs/Music/RJD2/2002 - Deadringer/03 - Smoke & Mirrors.flac
    
/mnt/nfs/Music/RJD2/2002 - Deadringer/06 - Ghostwriter.flac
    
/mnt/nfs/Music/RJD2/2002 - Deadringer/10 - Chicken-Bone Circuit.flac
    
/mnt/nfs/Music/FC Kahuna/2003 - Hayling/01 - Hayling _Original_.flac
    
/mnt/nfs/Music/Lamb/2003 - Between Darkness and Wonder/04 - Angelica.flac

    I’m trying to loop through it like so :

    while read -r line; do
    
 wavfile=$(basename "$line")
    
 wavfile="${wavfile%.*}"
    
 ffmpeg -i "$line" "$2/$wavfile.wav"
    
done <$1

    ...where $1 is where I would pass the name of the text file and $2 is the destination directory.

    Here is the output with the irrelevant ffmpeg junk pruned out :

    Input #0, flac, from '/mnt/nfs/Music/Rob D/1995 - Clubbed To Death/Rob D - 02 - Clubbed To Death _Kurayamino Variation_.flac':

    If you pay attention to the paths that ffmpeg reports don’t exist, you’ll see that a seemingly random number of characters has been removed from the beginning. This appears to happen on even numbered lines, but odd numbered lines work. I can only reproduce this behavior when using ffmpeg. If I replace the ffmpeg line with a simple echo statement, every file path is shown to be correct. How can this be ?

    Other suggestions of accomplishing this are also welcome, however I do need the files processed in the order by which I have them listed in the file.
