I've written it so that ffserver is kept alive until there are no clients connected to the stream, so it should still be alive even when ffmpeg bombs out.

hmm this isn't true on my system, unless something odd is happening. I just watched using top both ffmpeg and ffserver end at the same time, about 2 minutes after starting a stream. Is there some way I can get you some log or debug info?

yes,

in this file;
/var/www/mythweb/data/serverecording

These two lines have stdout and stderr redirected to /dev/null, change it to point to files in the same dir.

/usr/bin/ffserver -f /etc/ffserver.conf 1> /dev/null 2> /dev/null &

nice -n 10 /usr/bin/ffmpeg -i $DIRECTORY/$file -aspect 16:9 http://localhost:8090/feed1.ffm 1> /dev/null 2>> /dev/null &

EG.
/var/www/mythweb/data/ffserver.stdout
/var/www/mythweb/data/ffserver.stderr

and
/var/www/mythweb/data/ffmpeg.stdout
/var/www/mythweb/data/ffmpeg.stdout

So the first line will look like;
/usr/bin/ffserver -f /etc/ffserver.conf 1> /var/www/mythweb/data/ffserver.stdout 2> /var/www/mythweb/data/ffserver.stderr &

(all one line).
Please note that ffmpeg.stdout will grow very large.

Hope this helps.

BigB.

OK I outputted some log files. The same thing happened here as normal. The streaming stopped early and ffserver dropped out with it. The playing continued for a few more minutes and then stopped. Here is the output of my logs.

Code:

root@mythbox-be:/home/mythtv# cat var/www/mythweb/data/ffmpeg.stdout
root@mythbox-be:/home/mythtv#

Code:

root@mythbox-be:/home/mythtv# cat var/www/mythweb/data/ffmpeg.stderr

Hi,

I can't see anything abnormal in those files, the buffer underflow is pretty normal. anything in the stderr files?

As a side note, I see that i may need to detect the video format of the original and adjust the output at necessary.

In ffserver.conf change the frame rate from 25 to 29.97, and the frame size to 360x240. I doubt this will fix anything, but there is a slight change it might be more gentle on the encoder.

BigB.

Hey All

I am having difficult getting streaming to work correctly. When I select a recording to watch everthing seems to be working correctly however when i try to connect to a stream (http or mms) it buffers and seems like it starts to play but i don't get any audio or video. I am running R5E50. Does anyone have any tips or advice? Please let me know, thanks.

I have it working with VLC. Try the following settings

Video Codec:DIV3
Video Speed:128
Audio Codec:MP3
Audio Speed:32
Video Size:25%
Video FPS:5
Stream Protocol:http

When it tells you the address, copy and paste it into VLC under File>Open Network Stream>Network>http... radio button. You can play around with all the other settings besides video and audio codecs and stream protocol to get more quality dependent on the speed of your connection to the mythbox.

If you are trying to use WMP, I can get video, but no audio regardless of what I try in WMP 11.

Video Codec: must be WMV2, WMP doesn't support DIV3 natively
Stream Protocol: must be mms, http plays at like 1 frame per 2 seconds, apparently WMP's support of http is broken.

Everything else you should be able to choose whatever and get video, if not audio.
