• Stopped ffmpeg ip camera recording

  25 août 2016, par Amit Yadav

  I am using foscam ip camera. I want to record its stream in ts chunks and put no video screen when there is no stream available. I want to record 24 hrs video but I am not able to record it up to 24 hr. FFMPEG command stops inbetween. I am using below ffmpeg command

  ffmpeg -rtsp_transport tcp -i rtsp ://username:password@192.168.0.68:554/videoMain -t 86400 -c:v copy -c:a copy -map 0 -f segment -segment_time 10 -strftime 1 -segment_list_type m3u8 -segment_list /home/user/Desktop/rec/del20160725111733.m3u8 -segment_format ts -y /home/user/Desktop/rec/%Y%m%d%H%M%S.ts

  want no video screen like this http://www.electro-tech-online.com/customimages/2011/03/preview409-1.jpg

  Or any other way to record stream using java code so that I have more control over stream to check if it is recording or not.

• FFMPEG mkv to mp4 conversion lacks audio in HTML5 player

  3 avril 2020, par fmc

  I used ffmpeg to convert an mkv file to mp4 using this command line :

  



  ffmpeg -i input.mkv -c copy file-1.mp4


  



  The resulting mp4 plays fine (video and audio) on Linux Mint's Xplayer. But after uploading file-1, it played with no audio. So I uploaded another mp4 file-2, one I didn't have to convert, and it plays both video and audio without a problem. So whatever's going on with file-1 seems to be with my use of ffmpeg.

  



  The player I'm using is called afterglow. But the HTML5 player handles these two files the same way : file-1 & file-2

  



  Does anyone know why the ffmpeg converted file is soundless when played online ? Is there a different conversion command that ensures converted mkv files will play with sound by online players ?

  


• How to tag metadata m4v files using FFmpeg

  21 mai 2019, par jazz-e

  So I’m trying to tag metadata to a video file m4v from the filename. However, I can’t seem to find the answer in the man -h page and everything online shows how to pull the metadata from m4v.

  I’ve looked here on StackOverflow and also online for the answer and most are answers on pulling the metadata from the m4v file but nothing on tagging the file (other than stripping out metadata). I found this http://jonhall.info/create_id3_tags_using_ffmpeg/ regarding tagging an mp3 file, which I tried the syntax and it fails.

  Here’s the mp3 syntax I tried subbing out mp3 to m4v

  ffmpeg32 -i in.m4v -metadata title="The Title You Want" out.m4v

  Also tried the following as well

  ffmpeg -i "$filedir$name" -metadata title="The Title You Want" -c:v copy -c:a copy "$filedir$newname"

  This command works for removing the metadata from the file

  ffmpeg -i "$filedir$name" -map_metadata -1 -c:v copy -c:a copy "$filedir$newname"

  The error I usually get a syntax error.

  Any help much appreciated
