  • Should I blur video before compression or during using a filter with ffmpeg ?

    16 septembre 2016, par dtmp

    I have about 3 minutes of video of a street scene. I want the full frame of video blurred so the people, cars, etc. are not recognizable. In addition I want to make the video file size as small as possible for a web site video background. The original footage is 1920x1080, the final size will be 800x450. My question is : Should I blur the video before I compress it with ffmpeg OR should I use ffmpeg to blur the video during compression for best results.

  • Can't play MP4 after download

    14 août 2018, par joe

    I am using a downloader program in Firefox to download videos playing in Firefox. Most of the time final MP4 is playable. But sometimes I get MP4 file that looks good(shows file size) but shows no length of video in file explorer.

    I get this error log.

    Could not get information from media 'ESPN 2 (HD) Live Stream Channel' from file 'C:\Download\dwHelper\ESPN 2 (HD) Live Stream Channel.mp4'. The file might be corrupted.

    [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000024c3900] moov atom not found

    C :\Download\dwHelper\ESPN 2 (HD) Live Stream Channel.mp4 : Invalid data found when processing input

    It looks like moov atom is missing thus can’t aggregate PART file into final playable MP4.

    I understand that during download, PART file is created. Then later PART is aggregated into final MP4.

    So question is how can I make this MP4 to play ?
    or is it impossible to play cus moov atom was not properly downloaded ?

    Any thoughts ?
    Thanks

  • Can I programmatically insert audio from a Webm file into another Webm file ?

    18 janvier 2016, par andy

    I have two WebM files, both have video and audio.

    I want to insert the audio from one WebM file into the other so that the final WebM file has two audio "streams" playing simultaneously with the video.

    Is it possible to achieve this programatically ? Preferably with Ruby, or if not with a command line interface, maybe ffmpeg ?
