FFMPEG : Create timestamp based on actual creation time
2 juillet 2022, par Peder WesselDesired outcome


Add overlay with timestamp for each frame of a video based on the original creation time for the video. E.g. starting at 2022-03-26T15:51:49.000000Z and a second later in the video present 2022-03-26T15:51.50.000000Z


Approach


Creation_time stored in the file already, e.g. when running
ffmpeg -i input.mov"
it presentscreation_time : 2022-03-26T15:51:49.000000Z
.

Adding overlay with timestamp to video :

ffmpeg -i input.mov -filter_complex "drawtext=text='%{pts\:gmtime\:1507046400\:%d-%m-%Y %T}': x=100 : y=100: box=1" -c:a copy output.mp4


Challenge/ help needed


Need to replace the
gmtime\:1507046400
with the actualcreation_time
. How does one do it ?

http live streaming based on a m3u file
23 mars 2018, par 3agelx45I have an account on a platform of streaming (legal !). This platform provide me with a m3u file, the content looks like follow :
#EXTM3U
#EXTINF:-1 tvg-id="" tvg-name="|| something ||" tvg-logo="" group-title="",|| CAT1 ||
http://someurl.domain:1234/video1.ts
#EXTINF:-1 tvg-id="" tvg-name="video2" tvg-logo="" group-title="CAT1 part 1",VIDEO1
http://someurl.domain:1234/video2.ts
#EXTINF:-1 tvg-id="" tvg-name="video2" tvg-logo="" group-title="CAT1 part 1",VIDEO2
.
.
.
etcThis file works fine using vlc from home. but when I travel I use Hotels hotspots and some do block the connection to someurl.domain:1234.
is it possible to stream the m3u file using a light http server (stream the file from server side and reroute result to http). The idea is run a small iptv server from home on my raspberry which will allow me to bypass the "censorship" faced with some hotspots.
Thanks !
