Recording high quality video using a local buffer?
by Grant-45
::
Rate this Message:
Currently I have video recording working, but since I need higher
quality video I was trying to keep a buffer on the client side and then wait for the buffer to upload after the recording stops. The problem is I don't know what net status event to wait for to know when the buffer has finished uploading. Right now when a person clicks the stop recording button I set the camera and audio on the NetStream to null, and then wait for a NetStream.Record.Stop event, but I never get it. Should I wait for a NetStream.Buffer.Empty event instead? Or is there a better way to record higher quality video? I know this can't be that complicated. |

It won't help, it's caused by a nasty memory leak, which is triggered
after a certain type of decompression error. Me (and probably some more people on this list) circumvented the problem by changing the following in org.red5.server.net.rtmp.codec.RTMPProtocolDecoder: // Change this (around line 440): if (headerSize != HEADER_NEW && lastHeader == null) { log.error("Last header null not new, headerSize: {}, channelId {}", headerSize, channelId); lastHeader = new Header(); lastHeader.setChannelId(channelId); lastHeader.setTimerRelative(headerSize != HEADER_NEW); } // Into this: if (headerSize != HEADER_NEW && lastHeader == null) { log.error("Last header null not new, headerSize: {}, channelId {}", headerSize, channelId); return null; } This change will trigger an error status (which will disconnect the "offending" flash player) instead of bringing the whole server to its knees.

Grant,
I don't think there is a event associated with this. I have had to use a timer to determine with the Netstream's bufferlength reaches zero. That's when you want to finally close your Netstream. I haven't every been able to increase or control the speed at which the buffer empties to the server though; even when doing the entire implementation on localhost.
