Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

HTML5 audio and video support
13 avril 2011, parMediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
For older browsers the Flowplayer flash fallback is used.
MediaSPIP allows for media playback on major mobile platforms with the above (...) -

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

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)

Resize and overlay image on video in android efficiently
29 décembre 2016, par Bhushan LadheI want to resize image and video(2160 x 3840) to a same resolution(540 × 960) and then overlay image on video for whole time. This whole process is similar to capturing video and adding caption to it like snap-chat and saving it.
Since i am successful in doing so using FFMPEG library but it consumes considerable amount of time in processing.
I have searched the internet for other faster operations but no luck. I will post commands that i am using.
//1st command (video size from 59MB to 4MB, about time 110secs)
-i sdcard/VID_20161228_174315.mp4 -vf scale=540:960 sdcard/output540.mp4
//2nd command (image file , size done, time : a sec hence ignored)
-i sdcard/capture.jpg -vf scale=540:960 sdcard/capture540.png
//3rd command (time 80sec)
-i sdcard/output540.mp4 -i sdcard/capture540.png -filter_complex overlay=0:0 -r 30 sdcard/output_overlay.mp4So here using -preset and copying same audio from source did not work as expected.
Questions :
1) Should i use specific codec ?
2) How to achieve Minimum time for processing ?
3) Will applying multiple threads help ? If yes then how ? I want this process to work in background even if app is closed.
4) All other options that can combine to make an efficient solution ?
Log for 3rd command :
