  • ffmpeg converting .mkv to .264

    13 octobre 2015, par V. Panchenko

    I want to convert .mkv to .264.
    I try to do it using ffmpeg :

    ffmpeg -i input.mkv -vcodec copy -acodec copy output.264

    It works without errors, but when I try to play output.264 using ffplay :

    ffplay -f h264 -i output.264

    ffplay response is :

  • FFmpeg : Concatenating two huffyuv codec files in .avi container causing first video to be fine but other video is just static

    15 octobre 2015, par roy

    I have two .avi video files that I am trying to concat together.

    I have a files.txt that has in it :

    file './1_tmp.avi'
    
file './2_tmp.avi'

    There are only video streams, they look to be the same codecs/fps

    I am using this command to concatenate them :

    ffmpeg -f concat -i files.txt -c:v copy -y output.avi

    I don’t get any output from the terminal and it outputs a file.

    The file opens and the content in 1_tmp.avi plays fine, at the same quality, but when it gets to the point in the video where 2_tmp.avi should be, it’s pixelated static all the way through (see image below).

    static screen for second file after concatentation - mama **did not** say there would be days like this.

    If I use a command like :

    ffmpeg -i 1_tmp.avi -i 2_tmp.avi -filter_complex "[0:0] [1:0] concat=n=2:v=1 [v]" -map "[v]" output.avi

    I do get full output of both videos merged together, but it is dropped to an mpeg codec and the quality loss is noticeably prominent.
