NetStream.Play.Failed issue

[Alfonso]

Hi everybody,
since the release of flash player 11.2 I'm having the following issue
in Red5.

I publish a netstream in record mode. This netstream is audio-only.
Later, when I try to play the recorded .flv I always get the same
message status:

NetStream.Play.Failed.

This happens even with the publisher demo installed with Red5.

I repeat the same process with Flash Media Server, and everything is
OK.

This only happens with the combination Red5-Flash Player 11.2-play a
recorded audio-only flv

Any ideas of what could be happening?

I have the exact same issue, could not find a fix yet.

My guess is that they changed something in the handshake; I have not tested to verify this as of yet.

In which revision did the playback of audio-only FLV files get fixed? This was supposed to be a Flash Player 11.2.x issue, but it is fixed in the latest red5 revisions. I would like to see what changes you made to the code to make it work.

Thanks.

To solve the bug in previous version you have to set the netstream buffer to a minimal value ( 0.1 second) it's a flash player bug...

Hi, I tried your workaround but it didn't work. Thanks anyway.

I still would like to know which revision fixed this issue, I have to work with an older revision and I would like to patch it myself if possible.

Recently flash player 11.2 got a bug with audio look here :  https://bugbase.adobe.com/index.cfm?event=bug&id=3154302 

I fixed the probleme with  netStream.bufferTime = 0.001;

Regards.

Hi Yann, thanks for your answers.

Setting the bufferTime didn't work for me, I guess we are talking about different bugs. But I think I've found what was causing my problem. 

Red5 versions prior to r4213 put a videocodecid=-1 metadata in the audio-only files you recorded from Flash using only your microphone (apart from a fake non-valid video Stream). Flash Player 11.2.x versions determine files with such metadata are corrupted and won't play them (I think this is a bug too, but anyway).

In the aforementioned revision a placeholder metadata was introduced to avoid such behaviour (FLVWriter.java lines 425-433). As to what to do with your previously recorded audio-only files, you can fix them processing them with either flvtool2 or ffmpeg.

flvtool2 -UP <targetFile>

ffmpeg -i <targetFile> -vcodec copy -acodec copy <targetFileFixed>

Hope this helps users with older versions of Red5 and Flash player 11.2.x

So then the issue should be fixed in Red5 1.0 RC2 since r4213 is from 1 year ago while RC2 has been recently released.

Unfortunately with RC2 I can not even record/publish a stream (even when using the oflaDemo app), the following error shows up in the logs:

I have uploaded a compiled version of Red5 r4380 here:
http://dl.transfer.ro/Red5_r4380-transfer_RO-12jun-7ce58e.zip

We found both recording and playback of audio files works correctly with this version.

The issue is also solved in the recently released (8th of June 2012) Flash Player 11.3

No need for special versions of Red5 anymore.
