• FFMPEG how to record aac codec audio same time with wideo ?

  12 décembre 2017, par Gomi Odabaşıoğlu

  I am trying to use FFMPEG console tools effectively. Now I can record video and audio same time but my issue is audio is delaying. I use following code :

  C:\Users\gomid_000\Desktop\ffmpeg.exe -y -f dshow -i audio="Stereo Mix (Realtek High Definition Audio)" -f gdigrab -show_region 1 -framerate 60 -i desktop -map 0 -map 1 -c:v libx264 -preset ultrafast -pix_fmt yuv420p C:\Users\gomid_000\Desktop\out.mp4 -threads:1 4

  I do not know if I can automatically sync them together and prevent delay. Is it better to use AAC codec ? If it is how can I do that ?

• Record UDP stream with ffmpeg video+klv-data

  26 septembre 2017, par mfreiholz

  I’d like to record an MPEGTS UDP stream with ffmpeg binary to disk.

  This works in a stable network :

  ffmpeg.exe -i "udp://224.10.10.10:15006?multicast=1&timeout=360000000&reuse=1" -f mpegts -map 0:0? -map 0:1? -map 0:2? -c copy "C:/test.ts"

  The entire stream is saved to test.ts.

  Live Environment

  In my live environment it is possible that the connection is very bad or is not available at all (cable disconnect, device reboot, ...) for a few minutes. I want ffmpeg to simply continue writing upcoming frames to *.ts file. I don’t need the lost frames.

  Currently the following errors appears, if there was a too long brake between UDP frames :

  [mpegts @ 00000000003cf920] Application provided invalid, non monotonically increasing dts to muxer in stream 1: 11606399 >= 2084534
  
  av_interleaved_write_frame(): Invalid argument

  It looks like to be a problem with the timestamp. My idea would be to tell FFMPEG to ignore those errors and simply continue.

  Is it even possible with the ffmpeg binary or do I have to solve the problem with a custom C/C++ implementation using the library ?

  Thank you

  Update 1

  If I only record the video stream -map 0:0? and not the others it seems to work. Looks like the problem is associated with the second stream (No.1) which is KLV encoded data.
