• linux ffmpeg Live streaming cannot connect to another PC

  9 juin 2019, par Tae-Yeong

  I’m set ffserver and ffmpeg streaming code in the linux console terminal.

  ffserver => ffserver -f ./ffserver.conf (terminal 1)

  ffmpeg => ffmpeg -r 15 -s 640x480 -f video4linux2 -i /dev/video0 http://mylocalhostip:8090/feed1.ffm (terminal 2)

  It was working success in the localhost.
  But It could not connect other PC or Mobile.
  Firewall set disable.

  My desktop and mobile have a normal Internet connection.

  I want to Live-Streaming connect other PC or Mobile.
  How can I do ?

  Hardware = LattePanda
  OS = Ubuntu 16.04

  < ffserver.conf >

  HTTPPort 8090

  bind to all IPs aliased or not

  HTTPBindAddress 0.0.0.0

  max number of simultaneous clients

  MaxClients 1000

  max bandwidth per-client (kb/s)

  MaxBandwidth 10000

  Suppress that if you want to launch ffserver as a daemon.

  NoDaemon

  I expect to output of My WebCam Screen, but the actual output timeout.

  My desktop OS is Window10. And Mobile OS is Android.

• Unable to FW/RW video after remuxing multiple mpeg-ts to mp4

  21 juillet 2022, par Jona

  I have written custom code to concat multiple mpeg-ts files into an mp4 video file. I've used as reference the remuxing code sample.

  &#xA;

  I'm having issues with the final output. I'm unable to fast-forward or rewind as the video looses it's information and plays the same frame till the end. But if i play from the beginning it plays fine.

  &#xA;

  I compared using ffprobe my custom code remuxer results to that of using the following terminal command :

  &#xA;

  ffmpeg -i "concat:input1.ts|input2.ts|input3.ts" -c copy output.mp4


  &#xA;

  To my surprise, the videos look almost identical but I'm noticing some differences in the reported distance and keyframe values. I also did a hex comparison and see minor differences at the end of the file which tells me I've muxed the frames correctly. What could I be missing ? Any tips or ideas would be really helpful !

• Unable to scrub video after remuxing multiple mpeg-ts to mp4

  I have written custom code to concat multiple mpeg-ts files into an mp4 video file. I've used as reference the remuxing code sample.

  &#xA;

  I'm having issues with the final output. I'm unable to scrub the video on QuickTime. The final output seems to be missing something.
