LiveStreamRecord: Module for recording a live stream on demand

[cardillator]

Hi Charlie,

First of all, thanks for your response.

I'm playing the file locally, downloading the file by FTP.
the file format is FLV and is captured from the flash sample.
I'm not sure of the codec used, maybe the default used by Wowza, and encoder settings are on the same way.

How could I see which codec and encoder are being used?

Thanks in advance

What player are you using?

The player is FLVPlayer but have also used Adobe Media Player with the same result

hi,

I think me aso had the same problem while I was using the Livestream record...with
wowzamediaserver2.0.0...when trying to record an flv video file....had some problems...Installing the patch
WowzaMediaServer2.1.0-patch1.zip will resolve the problem...Or u can try to record the mp4 video instead that ....For that just use Stream: mp4:stream_name in the encoder....


For more recording options U can use Jconsole as well...

Think this will help..

same problem here.
I use livestreamrecord since 1.5 and I never get any big trouble. Last Thursday, I upgrade our server to WowzaMediaServer2.1.0 and it seems to be ok. But friday and today I find two record H264+aac where the mp4 is partially broken. The sound seems totally fine but the video frozen or is black temporarily. I already check logs and live streaming but I didn't find anything (no error, warning or strange trace). I will upgrade to patch1 tomorrow but it's actually bothering me.

I've been using the new LiveStreamRecord, and we're running into issues with combining files created with LiveStreamRecord with other files (via ffmeg).

A quick look at the info from ffmeg shows that the FrameRate is at 1000, which certainly doesn't seem right.

Here's the dump of the data ffmeg returns:

Array
(
    [Duration] => 23.288000106812
    [hasAudio] => 1
    [FrameCount] => 23288
    [FrameRate] => 1000
    [Filename] => /usr/sites/wowza/vim/19.mp4
    [Comment] => 
    [Title] => 
    [Author] => 
    [Copyright] => 
    [Artist] => 
    [Genre] => 
    [TrackNumber] => 0
    [Year] => 0
    [FrameHeight] => 240
    [FrameWidth] => 320
    [PixelFormat] => yuv420p
    [BitRate] => 293760
    [VideoBitRate] => 
    [AudioSampleRate] => 22050
    [FrameNumber] => 1
    [VideoCodec] => h264
    [AudioCodec] => mp3
    [AudioChannels] => 1
)

Any ideas?

I'm still hoping for some more events from the call(Record), but that's a different issue.

I'm stuck on this one, though, as we need to merge these fragmented files together. They seem to play via Wowza okay, though.

Is there any way to control the framerate and such? BTW, the livestream is from Adobe Live Media Encoder, it's set to 20 fps.

Does the resultant concatenated video play okay?

What does GSpot report in the Frame/s field?

We're extracting a snippet first, then concatenating that, e.g.

ffmpeg -i 20.mp4 -ss 2 -t 8 20.mpg

That works (or appears to), but when we try to convert this to an mp4 or flv file, we can an Unknown Format error

ffmpeg -i /tmp/20.mpg -sameq /tmp/20_test.mp4

Curiously, mplayer can play the file.

Is there a gspot command line program for linux-based systems?

You can try VLC instead, maybe mplayer for codec info. I don't have enough experience with ffmpeg to help directly.

gspot reports

Frame/s 24.390
Len: 0:23.256
Frms: 561
kbps: 294

So maybe ffmeg is just reporting odd values for some reason.
