Yup, download finished near midnight. Vlc shows 10:00:00, while avidemux only 45:45. There is an issue with a malformed H.264 bitstream in that video clip. You can rescue the entire clip with ffmpeg.
Copy your file to input.flv or rename the file to one without spaces in it. Then with command you can have a workable copy in avidemux 2.6:

Code Select

ffmpeg -i input.flv -vbsf h264_mp4toannexb -acodec copy -vcodec copy output.ts
