This woud require a decoder and encoder server-side. This encoding solution would capture web camera video and encode to H.264 or AAC then send it to Wowza for recording.Ĭapture the video server-side and transcode it on the fly from Sorenson Spark and Speex to H.264 and AAC.

Replace Flash on the client-side with an encoder such as Wirecast, Adobe Flash Media Live Encoder (read the EULA) or Nanocosmos ( ). There are two potential ways to get this to an H.264/AAC solution. It is connecting to the web camera, encoding the video and audio stream as Sorenson Spark and Speex (or NellyMoser ASAO) and sending it to Wowza over RTMP for saving to an FLV file. In your current setup the Flash player is acting as the encoder. I can send you the results of ‘ #mplayer -identify’ with either a recording file or my cocatenated file if it will help analyse where the audio is going wrong.

But it requires the ‘-fafmttag’ audio format tag, i have tried ‘0xf0’ and ‘0x08’ as found in but I think I am missing something with this as clearly I am not a video encoding expert (or even close). Has anyone had any experience with using mencoder to concatenate 2 flv files together without losing audio sync?Īlso I tried using the ‘copy’ codec instead of encoding it with ‘pcm’. I have looked through other forum posts and cant find anything which can help. #mencoder -oac copy -ovc lavc -srate 11025 -vf scale=320:186,harddup recording1.flv recording2.flv -o together.flvīut i have tried it with additional options ‘-mc 0’ ‘-ofps 25’ and ‘-noskip’. The current mencoder command I am using is: I am trying to cocatenate them together and the video always does this without any problems but I cannot get the audio in sync with the video. I have used WOWZA’s videorecording to record 2 videos. I am having a big issue which is taking me a long time to figure out.
