FFServer HTTP/1.1 WAIT_FEED bug

[barhom]

Fully reproducible bug that only happens once "FileMaxSize" is reached.

Below are ffserver configuration for a feed+stream.
FFmpeg is started like this;

ffmpeg -i INPUTMPEGTS ​http://localhost:8090/feed0.ffm

This creates a stream that ffmpeg transcodes into h264+aac in a flv container and publishes it as ​http://localhost:8090/feed0.ffm
The stream is then viewable/downloadable at ​http://localhost:8090/feed0.flv

Everything is working as expected and FFserver stats page shows that is is receiving data.
However, once FileMaxSize is reached new clients that connect has about random chance of around 20-40% of getting the data, the other times the stream connects however with no data being received at the client (wget/vlc).

When no data is being received the stats page in ffserver shows; HTTP/1.1 WAIT_FEED for the client.

Changing FileMaxSize to 100G would make the stream work for every client up until the file is 100G, then the same problems occurs.

Simulate client with wget;

:~# wget ​http://localhost:8090/feed0.flv
--2012-04-24 19:58:14-- ​http://localhost:8090/feed0.flv
Connecting to localhost:8090... connected.

Should be fixed, if there are cases left where it still fails, please reopen or open a new ticket if they are seperate issues.

I am still having this issue. It should be fixed in v. 1.2, right? I have installed ffserver via Homebrew.

Thanks!
