• ffmpeg show wrong with/height of video

  6 mai 2020, par boygiandi

  I have this video : https://media.gostream.co/uploads/gostream/9wkBeGM7lOfxT902V86hzI22Baj2/23-4-2020/videos/263a34c5a2fe61b33fe17e090893c04e-1587640618504_fs.mp4

  



  When I play it on Google Chrome, it's vertical video. But when I check with ffmpeg

  



  ffmpeg -i "https://media.gostream.co/uploads/gostream/9wkBeGM7lOfxT902V86hzI22Baj2/23-4-2020/videos/263a34c5a2fe61b33fe17e090893c04e-1587640618504_fs.mp4"


  



  It show video dimensions are 1080x1080

  And when I livestream this video to Facebook, it scaled vertical video into square form : https://imgur.com/a/A8dQ7j7

  



  How can I correct video size when livestream ?

  


• FFMPEG : Add timestamp to file name HLS

  7 mai 2020, par Neel Dutta

  I want to add timestamp to my file name in the following ffmpeg command (in nginx rtmp) :

  



  exec ffmpeg -i rtmp://localhost:1936/stream/$name 
                -c:v libx264 -b:v 2500k -g 30 -r 30 -s 1280x720 -vf "drawtext=fontfile=/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans-Bold.ttf: text=%{localtime}: fontsize=30: fontcolor=white@0.8: x=10: y=h-th-10" -preset fast -profile:v baseline -hls_list_size 0 -f hls /network_drive/$name-$date_%d-%b-%y-%H-%M-%S.m3u8
                -ss 00:00:05.000 -vframes 1 /network_drive/$name.jpg;


  



  What i want to achieve is the an .m3u8 file, with a filename of e.g : "stream_name-01-Apr-2020-10-46-45.m3u8", followed by its .ts files e.g : "stream_name-01-Apr-2020-10-46-450.ts, stream_name-01-Apr-2020-10-46-451.ts, stream_name-01-Apr-2020-10-46-452.ts", and so on.

  



  But the above command doesnt seem to work, and results in filename "stream_name-%d-%b-%y-%H-%M-%S.m3u8".
I've tried using strftime, but had no luck.
