    I can't get this one. Long stream of error messages and culminating in this:

    [mp4 @ 07253980] Non-monotonous DTS in output stream 0:0; previous: 528726, current: 0; changing to 528727. This may result in incorrect timestamps in the output file.
    https://hls.ted.com/videos/DavidMcCandless_2010G/audio/600k.m3u8?uniqueId=6495c7ff: Invalid data found when processing input

    I got an mp4 but it stopped right after the intro thing.

    Is it gettable do you think?

    Thank you. Excellent. Got it perfectly straight away. So what am I to take away from that?

    The url I had differs only in the '?utm_source' thing I think.

    https://www.ted.com/talks/david_mccandless_the_beauty_of_data_visualization?utm_source

    so when I see urls like that take off the 'utm' t hing and substitute '-f http-4181' ?

    no. that's not a general rule.
    you get that when in yt-dl you add -F before video link ex: yt-dl -F "http://videolink"
    with -F you have various format available. choose your preferred format then use: yt-dl -f xxx "http://videolink"

    Sorry, don't understand. The argument that worked didn't have a '-f' in front and I'm not clear where I would get the appended bit: http-4181 I do see that it had the -f at the end.

    i would like to know what that http-4181 is all about

    I have tried a similar input and got a return msg saying "live (best, worst )" for
    the available streams "error: unrecognized argument: ...".

    I wish capture streams and keep them.

    I need help, find no clues what the problem is. Please more examples
    including flash player such as netflix, js player, and flowplayer.
