  • Pipe Python Script To FFMPEG

    14 juillet 2017, par Go3Team

    I am using the following command that records and segments the video stream from an IP cam :

    ffmpeg -i rtsp://10.0.0.14/live.sdp  -c copy -map 0 -f segment -strftime 1 -segment_time 60 -segment_format mp4 -flags global_header "/rd/out%s.mp4"

    The python script outputs info every 1/4 second that I would like to pipe into the stream as an overlay or subtitle.

    Another question I have that isn’t too important at the moment is when playing back the segmented videos. The timeline on VLC starts at however many minutes into the stream it was recorded. So if it was the 4th video recorded, it starts at 4:00, but the end time is 1:00 which results in the progress bar being all the way over to the right when playing, and makes the video "unseekable(?)".

    Thanks.

  • webm to mp4 without loosing audio video sync

    9 avril 2018, par Kishore

    Iam trying to covert webm to mp4 using ffmpeg so that the output file is playable in all browsers.

    Iam using this ffmpeg command in ubuntu

    ffmpeg -i inpput.webm -f mp4 -copyts -vcodec libx264 -strict -2 -vf scale="380:-2" -pix_fmt yuv420p -profile:v baseline -level 3 output.mp4

    It is converting the file to mp4 but that file is out of sync in Mac safari browser and chrome browser. Means the audio and video is not syncing and sometimes the video gets stopped in between and audio goes on.

    If I play the input.web media file directly in chrome it is playing perfectly fine, the same input.webm is also playing good with firefox. But the converted mp4 is out of sync in safari on mac and all chrome browsers.

    However if the output.mp4 is played on ipad safari it is playing fine.
    The Mac safari version I tried is 11.03
    iPad safari version is 11.3

    Firefox and chrome are all latest.

    firefox : 59.0.2(64 bit),
    chrome : 65.0.3325.181 (Official Build) (64-bit)

    Please help me out with what Iam doing wrong.

    Thanks in advance.

  • Save StreamTitle tag in recording

    29 décembre 2022, par jarno

    Some streams have StreamTitle tag set and it changes from time to time. Is that information send only when it changes in the stream ? For example in this stream StreamTitle is used to tell the artist and the name of current song :

    


    ffprobe -v error -show_entries format_tags http://st.downtime.fi/sun.mp3


    


    Is the StreamTitle tag exclusive to MP3 streams ? Can one have it in Opus streams as well ?

    


    Can such information be added to the output file created when recording the stream by ffmpeg for example, to be able to see which song is playing when playing the recording later ? Could another tag be used to tell program name which may also alter in time ?
