  • Youtube Watch Me Android application closing unexpectedly

    18 septembre 2015, par Kichu

    I create android application from https://github.com/youtube/yt-watchme.

    When I try to create the event using the "CREATE LIVE EVENT" button.It throws some following error. I think it’s happening due to the camera permission issue.

    ERROR :

  • Converting HLS video with fmp4 segments to image thumbnails via ffmpeg with start offset using fast seek

    19 octobre 2022, par hellerahum

    I'm having trouble with what I think should be a basic use case for ffmpeg. What I'd like to do is take an hls video in fmp4 and output 30s of images at 10fps, using "fast seek" to start at an offset well into the video. This works with an Apple sample using ts segments, but not with fmp4 segments.

    &#xA;

    working sample (ts)

    &#xA;

    ffmpeg -ss 00:00:05 -i https://devimages.apple.com.edgekey.net/iphone/samples/bipbop/bipbopall.m3u8 -t 30 -vf fps=10 hls_samples/img%03d.jpg&#xA;

    &#xA;

    broken sample (fmp4)

    &#xA;

    ffmpeg -ss 00:00:05 -i https://devstreaming-cdn.apple.com/videos/streaming/examples/img_bipbop_adv_example_fmp4/master.m3u8 -t 30 -vf fps=10 hls_samples/img%03d.jpg&#xA;

    &#xA;

    The broken sample spits out errors like :

    &#xA;

    [NULL @ 0x123e30d20] Invalid NAL unit size (-2003396084 > 1673).&#xA;[NULL @ 0x123e30d20] missing picture in access unit with size 1677&#xA;

    &#xA;

    and then finally :

    &#xA;

    Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)&#xA;Conversion failed!&#xA;

    &#xA;

    When I re-encode the fmp4 video adding keyframes via -g 1 (still hls with fmp4) I'm then able to use the fast seek -ss flag before the -i , but i'd rather not do this in a 2-step process, and ideally would take the original hls/fmp4 manifest and output the thumbnails directly. Both samples work with the -ss flag after the input (slow seek) but I have some long (10+ hour) videos so that's not tenable. Anyone able to point me to what I'm doing wrong, or is it possible this is an issue with ffmpeg and its support for fmp4 ? I'm using ffmpeg v5.1.2 and have checked on both an M1 mac and Ubuntu system.

    &#xA;
