  • FFMPEG and HTTPS

    14 juin 2012, par Joel

    ffmpeg lists http as a protocol when I ask : ffmpeg -protocols

    Does this also mean support for a https url ? Do I need to encode this url somehow for the command line. I get "No such file or directory", but with http urls (at least some) it does work.

    A url (created for a Amazon S3 bucket) similar to this one does not seem to work :
    https://mycompany-video-test.s3.amazonaws.com/client/btr/video/xyz0011-x403-snap-n-go-ex/1/video/baby-laugh-ripping-paper.mp4?AWSAccessKeyId=AVIAZL9J6SIRPAA&Expires=1323709667&Signature=pTvS9F2do2t8%3D

    I suspect the format of the url is problematic, I've also tried enclosing in quotes... Yes, this URL does not currently work as it has expired, but even while its valid, its a problem.

    In short :
    1) Should https work ?
    2) Do I need to format the url somehow ?

  • avio : cosmetics, prettify AVIO_SEEKABLE_NORMAL

    avio : cosmetics, prettify AVIO_SEEKABLE_NORMAL

    Move the doxy above the definition, change the value itself to the
    
(1 << n) pattern, which is more readable for flags.

  • Extract motion vectors from x265 (HEVC) encoded video with ffmpeg/libavcodec ?

    3 juillet, par John Allard

    I know that one can extract the motion vectors from an h264 encoded via by first setting the flag

    &#xA;&#xA;

    av_dict_set(&amp;opts, "flags2", "&#x2B;export_mvs", 0);&#xA;

    &#xA;&#xA;

    then you can query the side-data for the motion vectors by doing this

    &#xA;&#xA;

    sd = av_frame_get_side_data(frame, AV_FRAME_DATA_MOTION_VECTORS);&#xA;

    &#xA;&#xA;

    When I looked online to see if you can do something similar with HEVC encoded videos, I wasn't able to find any information. All I found was this by the definition of "AV_FRAME_DATA_MOTION_VECTORS"

    &#xA;&#xA;

    &#xA;

    Motion vectors exported by some codecs (on demand through the&#xA; export_mvs flag set in the libavcodec AVCodecContext flags2 option).

    &#xA; &#xA;

    The data is the AVMotionVector struct defined in&#xA; libavutil/motion_vector.h.

    &#xA;

    &#xA;&#xA;

    but there was no information on exactly which codecs export this motion vector information. How would I go about finding this out ?
