Media streams produced by FFmpeg or GStreamer are not received via some ISPs

Well, you will not ignore this annoying amount of lost packets in the Consumer, right?:

  nackCount: 3498,
  nackPacketCount: 55662,
  packetCount: 8665,
  packetsDiscarded: 0,
  packetsLost: 5722,
  packetsRepaired: 5785,
  packetsRetransmitted: 55412,
  pliCount: 176

Of course no, I’m just wondering how it might happen!

@ibc

Which means that, indeed, most packets are lost. In the Producer or in the Consumer side. But you are not checking the packet lost in the Producer.

I’m confused. It’s obvious, as the stats shows, that the packet lost is happening in the consumer side. What do you mean by “But you are not checking the packet lost in the Producer”? Is there any difference between the producer stats fetched by Consumer.getStats() and the one by Producer.getStats()?

I also repeated the test with announcing support for NACK/PLI and GStreamer, which users have stated it supports that, and the same result.

@ibc

Somehow this is becoming a question about mediasoup when there is no real information about how good your ffmpeg or gstreamer sender is sending media. mediasoup cannot do magic if the sender is sending bad.

Okay, If you think this is a ffmpeg/gstreamer issue then I stop investigating.
