  • FFMPEG How to apply subtitles [ass] on a live video stream

    19 août 2014, par Lewisou

    I am going to develop a camera recording application.

    One of the feature is to apply subtitles while recording. Users can key in subtitles on the camera preview screen when the camera is recording.

    I know I can apply the subtitles after the record is finished by running :

    ffmpeg -i ./file.mp4 -c:v libx264 -c:a copy -vf "ass=t.ass" out.mp4

    but which takes a very long time. So it will be better to do it on the fly (while recording a video).

    Notice : the subtitle itself is also a live-stream.

    Any one help ?

  • ffmpeg with multiple live inputs [closed]

    9 juin 2013, par maddanio

    we are trying to get ffmpeg to combine multiple live streams into one. In principle we got it to work by mosaicing the streams like so :

    ffmpeg -rtsp_transport tcp -r 25 -i rtsp ://root:password@192.168.178.91:554/axis-media/media.amp \
    -rtsp_transport tcp -r 25 -i rtsp ://root:password@192.168.178.92:554/axis-media/media.amp \
    -filter_complex "[0:0]pad=iw*2:ih[a] ;[a][1:0]overlay=w" ...

    the problem though is that ffmpeg seems to start the input streams at significantly different times, so that there is about a 1 second shift between the streams, that remains throughout. Now we do have correct time stamps (pts) on both streams. Can we somehow tell ffmpeg to respect those and use them to align the streams correctly ?

  • Is it possible to use FFMPEG for h264 live decoding ?

    9 avril 2018, par elpha01

    I’m receiving in my C#/.NET application a H264 stream as byte arrays.
    Firstly I receive the SPS and PPS and then all NAL_units.

    I haven’t find good tools to make h264 decoding so I’m currently using FFMPEG for testing with this article as help : A Simple c# Wrapper for ffMpeg

    For the moment I write the sps and the pps in a provisory .264 file with the first NAL unit then I decode it with FFMPEG. It works for the first frame but I don’t know how I can decode the following frame. I tried to rewrite the SPS and PPS in a second file with the second NAL unit without the first one but it doesn’t work.

    How can I use FFMPEG to decode a live h264 stream when receiving NAL units.

    Thank you
