  • ffmpeg with Videoconverter.js MTS to .mp4 conversion issue

    24 juin 2014, par user3679718

    I’ve been scratching my head over this issue and going through dozens of google search results to find a solution to this, but no luck. I’ve got an issue when trying to convert MTS to mp4 with Videoconverter.js, which uses ffmpeg commands for converting video. I have installed ffmpeg, and run successfully .webm to .mp4 conversions. I’ve changed the Videoconverter.js file that specifies files to be used in the terminal, and I’m using commands from tutorials for MTS conversions (I’ve tried multiple options already), but to no avail. I keep getting "File not found", although it certainly is there, next to .webm which I converted before successfully.
    Anyone know what this might be ?

  • Converting GridFS file object to File object to upload via carriewave then process with ffmpeg in Rails

    20 juin 2014, par Ojash

    I have a GridFS file object

    Mongoid::GridFs::Fs::File _id: 53a277dc700ca7ac146f5797, length: 2237337, chunkSize: 261120, uploadDate: 2014-06-19 05:40:44 UTC, md5: "390968a8ef198f8537495468366f67b9", filename: "720p_5.MP4", contentType: "binary/octet-stream", aliases: nil, metadata: nil

    Now I need a Tempfile(or File will do) instance from that

    File:/tmp/fileupload20140620-4601-19via7k

    Since the file that I process is a video file i need to further process it with the ffmpeg to get different versions of the video file

    normally I could get a tmp file but the tempfile size seems to be quite low for a video file and the ffmpeg also gives error, may be the temp file created is not correct. I have no idea what did i do wrong.
