RED5 1.0.2 recorded FLV convert to Mobile/HTML5 format with FFMPEG av out of sync
14 août 2014, par Daew daweI have problem with recorded video in Red5 v1.0.2 (i had issues with previous v1, it does not recorded any video, with 1.0.2 it works). When I record flv I want to convert it to some mp4. But I have problem with settings, because every time there is some issue with quality/audio sync. Can u please help me how to convert with ffmpeg (in future automatic process on server).
Second problem is that in flash client buffer length is always 0, but in v0.8 it was filled and on end I waited until empty, here I’m not sure how long should I wait. I founded this url http://code.google.com/p/red5/issues/detail?id=312 where they said to wait until i get UnPublish.Success, but that event I got only after ns.close()
My flash client record settings is (FP10) :
video :
- resolution = 640x360
- fps = 30
- keyframeinterval = 15
- video quality = 90
- bandwidth = 0
audio :
- microphone codec = SPEEX
- encodeQuality = 9
-
silencelevel = 0
-
bufferTime = 15
recorded video parameters in VLC (translated from czech to english) :
video
- Codec : Flash Video (FLV1)
- Resolution : 640x360
- format : Planar 4:2:0 YUV
audio
- codec : Speex Audio (spx )
- frequency : 16000Hz
- bits per sample : 16
- data flow : 16 kb/s

what I tried with ffmpeg (I’m ffmpeg newbie).
First I recorded 33sec long video
when I convert audio with command :
ffmpeg -i test.flv -ar 44100 -ab 160k -ac 1 output.mp3
, then the audio have only 30secI tried this commands, but no one with good solution
ffmpeg -i test.flv -vcodec mpeg4 -acodec libvo_aacenc output.mp4
ffmpeg -i test.flv -acodec libvo_aacenc -aq 200 outputsss.mp4
ffmpeg -i test.flv -c:v libvpx -c:a libvorbis output.webm // here is sound synced good - but sound have repeating silence lags (every 1-2s)really thank you for your help, I’m fighting with conversion many days :(

FFMpeg - Merge multiple rtmp stream inputs to a single rtmp output
5 septembre 2013, par Paulo Miguel AlmeidaI'm trying to combine/merge two rtmp streams and then publish 'em to another stream
Ex. :
ffmpeg -i rtmp://ip:1935/live/micMyStream7 -i rtmp://ip:1935/live/MyStream7 -strict -2 -f flv rtmp://ip:1935/live/bcove7
The scenario is the following, I got a stream which comes from an user's microphone that
is the first one (micMyStream7) and I also got a stream from another user but this one has audio and video(MyStream7).As they are talking to each other when a user is speaking, the other one would only be listening to and vice versa.
My idea is to set up a third stream called (bcove) which would "merge" both of them so that I could have spectators who would only be listening to the entire conversation between them.
This is the log that ffmpeg printed although I couldn't recognize any message which helped me out.
paulo@paulo-desktop:~$ ffmpeg -re -i rtmp://ip:1935/live/micMyStream7 -i rtmp://ip:1935/live/MyStream7 -strict -2 -f flv rtmp://ip:1935/live/bcove7
