getting ffmpeg to listen on specific port on amazon ec2
12 juillet 2013, par user1913115I have a streaming device which can stream to any udp address/port, so if i set it up on my network , and open ffmpeg with this command :
ffmpeg -f mpegts -i 'udp://0.0.0.0:2223?fifo_size=1000000&overrun_nonfatal=1' -re -y -strict experimental -vcodec copy -f mp4 main.mp4
it works fine, i get the main.mp4 file recorded.
also, when i check lsof -i it shows that ffmpeg is listening on port 2223however, when i run the same command on amazon ec2, it doesn't record anything. i checked, the port 2223 is open in the security group. and if i run this command, it gets packets fine :
nc -u -l 2223
however when i run lsof -i in amazon ec2 it shows that ffmpeg is listening to a random UDP port (e.g. 42195) every time
has anyone run into this problem ? -

Amazon Elastic Transcoder vs FFMPEG [on hold]
17 janvier 2015, par KiranDI’m developing a website (php based) and there is a provision to upload videos in different formats. I’m using HTML5 player for the front end presentation. So, as the ideal format that is supported by most of the browsers is mp4, I tried using ffmpeg and it works fine.
I would like to know which transcoder (Amazon Elastic Transcoder or FFMPEG) would be best for handling conversions parallely when there is a huge traffic.
There could me approximately thousands of users watching the videos and may be hundreds uploading the videos at the same time. I’m using Amazon EC2 for deployment and the traffic is mostly spiky (not flat).
I’m not sure about the acceptable speed. But, I need the one which can transcode the videos much faster.
