• 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.

  Before it was that there was no ffmpeg buildpack on heroku, I added it with
https://elements.heroku.com/buildpacks/jonathanong/heroku-buildpack-ffmpeg-latest

  


  But now I just get state changed and see no errors. Any help would be greatly appreciated !

  


• gst-inspect-1.0 do not see avdec_h264

  16 octobre 2020, par Marat Zakirov

  Previously I installed gstreamer via conda and its (good) plugins
next I installed gst-libav via sudo apt-get install gstreamer1.0-libav next I used apt-file list gstreamer1.0-libav to see installation path and found it to be /usr/lib/x86_64-linux-gnu/gstreamer-1.0/ next I read running gstream manual and then

  


  GST_PLUGIN_PATH=/usr/lib/x86_64-linux-gnu/gstreamer-1.0/ gst-inspect-1.0 avdec_h264

(base) marat@user-System-Product-Name:~$ ls -lh /usr/lib/x86_64-linux-gnu/gstreamer-1.0/ | grep av

-rw-r--r-- 1 root root  72K мар 21  2020 libgstwavparse.so


  


  It found many new modules but didn't found avdec_h264. What I am missing ?

  


  UPDATE :

  


  I just want way to use gstreamer via conda virtenv python appliation. If you know valid way to do so I will consider your reply as answer.
