Encoding error with Sidekiq
14 mars 2017, par DavidKIm following this tutorial https://www.pubnub.com/blog/2015-12-08-building-video-sharing-app-server-messaging-ruby/ on Building a Video Sharing App. Its a bit outdated and Ive already had to fix a view issues to get this far but Im pretty lost now with this latest issue. I believe its something to do with sidekiq. When I try uploading a video it seems to work and shows up on the database, but I get a "Video is still being encoded." message.
This is the log :

Merge all .h264 files in directory in alphabetical order
9 mars 2017, par nicolashahnI have a camera that records in 5 second clips with filenames that are timestamps :
2017-03-08-09-54-27.334326-000000.h264
2017-03-08-09-54-27.334326-000001.h264
2017-03-08-09-54-27.334326-000002.h264
2017-03-08-09-54-27.334326-000003.h264
...What is the easiest way to merge these in order into one video file on OSX ?

RTP packets detected as UDP
28 février 2017, par user3172852Here is what I am trying to do :
WebRTC endpoint > RTP Endpoint > ffmpeg > RTMP server.This is what my SDP file looks like.
var cm_offer = "v=0\n" +
"o=- 3641290734 3641290734 IN IP4 127.0.0.1\n" +
"s=nginx\n" +
"c=IN IP4 127.0.0.1\n" +
"t=0 0\n" +
"m=audio 60820 RTP/AVP 0\n" +
"a=rtpmap:0 PCMU/8000\n" +
"a=recvonly\n" +
"m=video 59618 RTP/AVP 101\n" +
"a=rtpmap:101 H264/90000\n" +
"a=recvonly\n";What’s happening is that wireshark can detect the incoming packets at port 59618, but not as RTP packets but UDP packets. I am trying to capture the packets using ffmpeg with the following command :
ubuntu@ip-132-31-40-100:~$ ffmpeg -i udp://127.0.0.1:59618 -vcodec copy stream.mp4

libpostproc 54. 2.100 / 54. 2.100All I get is a blinking cursor and The stream.mp4 file is not written to disk after I exit (ctrl+c).
So can you help me figure out :
- why wireshark cannot detect the packets as RTP (I suspect it has something to do with SDP)
- How to handle SDP answer when the RTP endpoint is pushing to ffmpeg which doesn’t send an answer back.
Here is the entire code (hello world tutorial modified)
