How to record using mp4

[corriepotter]

I see that 1.7 now allows for recording of webcams using .mp4 but how do you do it? Is there documentation somewhere?

Thanks!

Are you trying to record webcam data that is being published by the Flash player using the Camera and Microphone objects? If so then this type of video/audio (Sorenson Spark, Nelly Moser ASAO and Speex) cannot be recorded in an MP4 container.

are there any options to covert it to mpeg4 serverside? Wowza is on a windows box.

No, Wowza doesn't do that.

Do you know of other software that can? We are using a webcam to record using wowza but are missing out on every device that does not support flash. Do you know of any software that windows can (run command line, or service) to convert the .flv to .mp4 server side?

You can probably record mp4 content from the webcam, but not with the encoder built-in to Flash plugin. Use Wirecast or Quicktime Broadcaster, or most of the encoding solutions on the Live Encoder forum will send h.264 to Wowza which you can record to mp4 container.

We are using ffmpeg to convert webcam recordings to H.264/AAC quicktime files. The set of available options in ffmpeg is pretty massive, so I'd send you to the ffmpeg website in order to figure out a full set of transcoding parameters. We have it grab a snapshot png every few seconds, too, which it can do while it is transcoding.

Great! Thanks for the information. Do you have flash trigger the ffmpeg app once the flv file is done recording?

I'm trying to get ffmpeg to transcode my flash-webcam-records, too. but out of the _several_ encode-options I've found and tried, not a single one worked out for me. whenever the conversion itself was "working" then there was no sound in the resulting mp4-files and they didn't play on the iPhone, only in Safari.

I already noticed that aac-support in ffmpeg kinda sucks and added -strict experimental to get it to "work" (as described), but I don't come any further from here.

Would you be so kind and give me a hint on which combination of options works for you? Which versions of ffmpeg and x264 do you use?

I'd be extremely thankful for any help*or suggestions!
