  1. Re: HOWTO: Install and use the latest FFmpeg and x264

    I can't contribute much due to being in the Pleistocene epoch (NVIDIA GT 240...queue laugh track).

    I'm not sure how much of that patch mentioned in the PDF is outdated. It does provide a scaling...
  2. Re: HOWTO: Install and use the latest FFmpeg and x264

    libfaac has now been removed.



    Makes sense. Didn't even notice that commit.
  3. Re: HOWTO: Install and use the latest FFmpeg and x264

    Unfortunately my hardware is too old to try nvenc so I have no experience with it and am unable to try it.

    As a starting point I recommend rooting around in the FFmpeg configure file to see what...
  4. [SOLVED] Re: Trim Video with Multiple Audio Tracks using AVCONV

    avconv is gone. It appears you are actually using ffmpeg which is better anyway.

    As you noticed the default stream selection behavior is to select only one stream per type. Once you use the -map...

    No, but consider doing so if the input is interlaced. Otherwise you may see combing artifacts in fast motion scenes.

    [SOLVED] Re: Winff

    If it is a typical video DVD then handbrake is your easiest solution.

    if it is just a data DVD with a normal video file then you can use ffmpeg directly. Since you mentioned a VHS I'll assume it's...

    Unfortunately that's not the complete output. I need to see the complete output from the command.

    Why are you adding "-flags -global_header"?

  10. [ubuntu] Re: How to reduce my file size without losing its quality?

    You can't technically use a lossy encoder without losing quality. However, you can't use a lossless encoder because the file will be huge, so you have to accept some quality loss. This does not...
  11. Re: How to permanently rotate iphone videos

    FFmpeg has for some time been able to automatically rotate video based on the rotate metadata:

    ffmpeg -i input.mp4 -c:a copy output.mp4
    No need for any filters or messing with metadata. If your...
  12. [SOLVED] Re: Command Line to bulk convert WMV to MP4

    I ignore attempting to adhere to mod16. Hardly makes any difference.
  13. [SOLVED] Re: Command Line to bulk convert WMV to MP4

    You can't re-encode to a lossy format without losing any quality. However, you can give it enough bits that you probably can't tell the difference.

  14. [ubuntu] Re: How to set color and font of subtitle in ffmpeg?

    You can use the "ASS v4 styles":

    In PrimaryColour the H00 is the alpha (transparency). H00 is...

  16. [SOLVED] Re: FFMPEG compile failure: Unknown option "--enable-libfaad".

    libfaad support was removed from FFmpeg in 2010 due to the maturation of the native FFmpeg AAC decoder.

    [SOLVED] Re: help for a simple bash script

    Use ffprobe instead which eliminates the need for the redirect and grep:


    $ ffprobe -loglevel error -select_streams a:0 -show_entries stream=codec_name -of default=nw=1:nk=1 input.foo
    aac
  18. [SOLVED] Re: FFMPEG compile failure: Unknown option "--enable-libfaad".

    That's an ancient and utterly outdated "guide" that appears to be yet another ripoff of the compile guide that used to be on these forums. It is was moved to the FFmpeg Wiki.

    [ubuntu] Re: Merging video with a data file

    I second SeijiSensei's recommendation to use ASS. It gives you the choice of softsubs or hardsubs. Using softsubs will allow you to keep the video as-is with no re-encoding.

    You didn't mention your Ubuntu version.

    Are you sure you even need a PHP wrapper for ffmpeg? Especially one that has been dead since 2007.
