After you record the stream to Flash Media Server, process it with the F4V Post Processor tool to play it back on the desktop or using progressive download (you can stream it without using the Post Processor):

My FP11 H264 recording content plays fine, when live and as vod content via FMS. However nothing recognises it like, media info, mp4info, mpui or FFmpeg when inspected and even VLC Player can not play it. FLVCheck says its ok. MP4UI did say the atom size was too small, so I can only think FP11 is not creating the container within the MP4 spec.

I would like this raised as a bug! Point me to the correct url please.

Thanks. I can process now, not sure I was doing wrong before

@ImAStreamer - Yes, that's what I'm suggesting. FFMPEG should be able to convert to a proper mp4 container. Just be sure to change the output audio codec to something mp4 compliant (mp3 or AAC)

One more bit of advice...

The AAC encoder in FFMPEG (FAAC) is terrible, and tends to result in poor quality at low bitrates. If you're transcoding to AAC, you'll likely want to use 128kbps or higher. If you workflow and endpoint targets allow for it, I'd go with MP3 audio.

From a quality perspective, I prefer Nellymoser. Speex encoding in FP is limited to 16kHz, where Nellymoser is capable of 44.1khz. For voice, the difference isn't all that noticeable, but if there's any music involved, you'll find that the sounds is a bit dull when using speex, as the higher frequencies aren't represented.

Also, if your application involves multiway communication and you want to take advantage of AEC, your only option is Speex, as AEC doesn't work with Nellymoser.

From a licensing standpoint, Speex is the clear winner. To be completely legal, you'd need a license from Nellymoser to decode the audio on the server side using FFMPEG, and that license is $7500 per year per server the last time I checked. Speex on the other hand is not patent encumbered, and (AFAIK) requires no licensing.

That said, if you're in a position where codec licensing is an issue, you'll want to look into an MP3 encoding license for your implementation as well.

None that I'm aware of.

As I mentioned before, I've been using Wowza lately (and h.264/speex to flv works fine there), so perhaps this is just something that FMS won't do. Maybe someone from the FMS engineering team will have suggestions about how to record a file that anything other than FMS can read.

Using my latest H264 recording application I was able to use FFmpeg to transcode to AAC. I understand you need to use the flvpackager to make the recorded mp4 playable direct from the desktop.

JC I suggest posting your application code (bits you are using for h264 recording) for forum users to debug.

Sorry I ment for ImAStreamer

I think what Jody was getting a was the inclusion of ulaw and alaw (pcm) audio in the flashplayer. The trouble there is, unless you're going to use a really low sample rate, the bitrate required for pcm is going to be very high, and (if I'm not mistaken), the flashplayer will not perform AEC for pcm.

@AdrianWilkinsUK - I would expect that you can't play those files outside of FMS without transcoding. Speex and nellymoser aren't mp4 compliant. They -might- play in the flashplayer (haven't tried that... but maybe the FP eng team has something in place there), but other programs won't.

anyone?

Hi,

When encoding live in H264 with the FP 11  then playing it live on another client (through FMS r) the video sometimes (1/3 of times) has major skips or jerks. It's almost as if the video goes back to some older keyframes and then returns to live. Same experience with non-h264 produces smooth video.

If the server (FMS ) records the video, the replay looks smooth, which is strange because I would have assumed the FP was not encoding well with H264.

Has anyone had this issue? please reply

Thank you.

@simpleton how can i send you my files.send me ur email id so that i can send u my files.
