  • Invalid pixel aspect ratio in ffmpeg

    26 septembre 2014, par dudeofea

    I want to scale a video to a certain size using ffmpeg, but I get the following error :

    I’ve read around and it seems this was a past bug but that was 3 years ago. I’ve tried running this command with version 2.4.1, 2.3.3, 2.4.git (compiled from source Sept 16, 2014), and N-40951-g1ea7a3e (Newest static build) and they all fail.

    EDIT : When I say fail I mean that the video is not playing at the proper resolution. The file’s properties say that it is 1000x64 but VLC plays (as well as my website using a <video></video> tag) it with the original aspect ratio with the new width which is not what I want. I want a crunched up video the same size no matter what.

    Is there something I’m missing ?

  • mlpdec : support TrueHD streams with an Atmos substream

    mlpdec : support TrueHD streams with an Atmos substream

    The fourth substream is being discarded, since its not raw audio data,
    
but an encoded Atmos stream which needs a specialized decoder.
    

    Fixes decoding of the true hd stream from Transformers\ -\ Age\ of\ Extinction\ 2014\ 1080P-003.mkv
