Issue trying to stream RTSP to RTMP (live) through NGINX
30 juin 2016, par taansariI want live RTMP streaming through nginx. I setup this server on a public ip (linux - CentOS), using this tutorial : https://notehub.org/rcfdu.
My target is : RTSP source -> transcode to RTMP -> recieve on nginx (live ip),
Then, I want to receive this stream through server ; something like :
nginx -> ffplay.
On transmission side, I have ffmpeg application, and on receiver side, I have ffplay application.
I have setup everything I could think of, and I can see it is properly setup (apparently). But, when I try to stream using similar command :
ffmpeg -i rtsp://aaa.bb.ccc.ddd/vod/mp4:filename.mov -f mpegts rtmp://<live ip="ip" address="address">:1935/live/
</live>I get lots of messages (where everything looks alright) :
ffmpeg -i rtsp://aaa.bb.ccc.ddd/vod/mp4:filename.mov -f mpegts rtmp://<live ip="ip" address="address">:1935/live/

lowpass filter Q factor online simulator (bode plot)
5 novembre 2016, par user1320370I like to add a low pass filter on a audio file myfile.flac with ffmpeg.
The parameters to choose are the frequency and Q-factor or slope.
ffmpeg -i myfile.flac -af "highpass=f=9000:width_type=q:width=0.707" output.flac
The default q-factor is 0.707.
I like to increase the q-factor but a too high value can cause excessive resonance.
For this reason before do it can be useful to test with a bode plot simular (online if exist) that can accept filter type (lowpass, highpass) , frequency and Q-factor.
Someone can please send a link of a bode plot that show a simulator like this ?
thank you !!

Fixing A/V sync issues with RTP/RTCP sent from mediasoup
10 décembre 2017, par artushinA little background : I’m attempting to record a webrtc call being made through the mediasoup v2 SFU. I’m using mediasoup’s
room.createRtpStreamer()method to generate a stream which mirrors RTP/RTCP to ffmpeg. Two streamers are created for audio and video within 30ms of each other and begin broadcasting. FFmpeg then spins up and starts accepting. Pretty sure RTCP is working since ffmpeg is always starting with a keyframe despite being started after the streamer begins broadcasting.The problem is that I encounter audio/video desynchronization with seemingly random offsets. My current theory is that this offset is based on how old the last keyframe is that RTCP requests to start the stream. See below for ffmpeg configuration and output but my question is : what ffmpeg arguments can I use to adjust the video frame timestamps to match the audio frame timestamps or vice versa ? I’ve messed around with
-map 0:0,0:1 -map 0:1,0:1but it doesn’t seem to do what I’m looking for.ffmpeg flags :

dts=0.260 pts=0.260Notice how the first frame for stream #1 (video) starts after a number of audio frames ? Specifically, it starts at stream #0 dts/pts 0.18. In this situation, the a/v sync issue is pretty much unnoticeable, but with a bunch of repros, I’ve determined that the a/v sync offset is always the duration of however long audio frames were sent before the first video frame (sometimes seconds). I’m consistently starting the RTP streams only tens of ms apart, so I can’t control for this variance on the input side.
After the initial audio frames come in, the first video frame has a dts/pts around 0. What ffmpeg setting would I use to adjust the timestamps accordingly ? I don’t care about losing the starting audio that doesn’t have video, so any solution that would adjust the timestamps works.
