• How to decode two Dolby E audio streams simultaneously with ffmpeg ?

  11 août 2022, par David

  I'm trying to decode 2 Dolby-E audio streams simultaneously.

  


  ffmpeg -non_pcm_mode copy -i C:\vlc-record.ts -map 0:3 -map 0:4 -c:a pcm_s24le -f s24le - | ffplay -

  


  Using -map 0:3 it works for one at a time but when I add the second one -map 0:4 it only process the first one and there is just one stream on my dolby_e output pipe.

  


  Is there a way to create a two streams multicanal non-pcm output from 2 Dolbys PCM streams ?

  


  I tried to find a solution with named pipe but it seems like windows command line doesn't accept this. I also tried to merge the PCM streams but then it says Invalid data found when processing input.

  


  I can't make it with 2 pass because I'll be using it with udp live video streams.

• FFMPEG RTSP stream to multiple output, one mp4 and also restream

  16 août 2022, par csonty

  I would like to seek your help with FFMPEG and how to use it properly on Windows and Linux. I have to get the camera RTSP stream and record it into 1 minutes segments and also stream at the same time.
I did try to stream it to rtsp, but it didn't work at all [f=RTSP]rtsp ://ipaddress:554/mystream , it stuck and did nothing.

  


  I did also try to add the -use_wallclock_as_timestamps 1 but it didn't do anything. I also tried to add the -flags +global_header, but not sure, how to add it into this script.

  


  I did try it on both Linux and Windows with the following commands (not sure how to create a bash script from it)

  


  Linux :
./usr/bin/ffmpeg -i 'rtsp://username:password@192.168.68.99:554/Streaming/Channels/101/' -c copy -f tee -map 0:v '[f=segment:strftime=1:segment_time=60]wwcam99-%Y-%m-%d_%H-%M-%S.mp4|[f=mpegts]udp://10.10.3.251:5555'

  


  Windows :
ffmpeg -i "rtsp://username:password@192.168.68.99:554/Streaming/Channels/101/" -c copy -f tee -map 0:v "[f=segment:strftime=1:segment_time=60]wwcam99-%%Y-%%m-%%d_%%H-%%M-%%S.mp4|[f=mpegts]udp://10.10.3.199:5555"

  


  It records the files and the stream can be viewed on the localhost (not sure why I cannot view from other machines even if the firewall is off, but it might be a network issue)

  


  This is the output with mostly error messages that I couldn't fix :
