[mythtv-users] Problems with mythweb and flash streaming.

[Alex Fazzari]

I'm having a problem getting flash streaming working through mythweb.
I've searched these lists and the web and as haven't seen a similar
problem - fingers crossed it's an easy one.

I have modified the mythweb/modules/stream_flv.pl file to output the
ffmpeg command to a log file.  On pressing the play button in the
flowplayer app I get the ffmpeg output pasted below.

It seems to be processing the file fine but is not producing any
output (0 size and 0 bitrate).  I have checked the permissions of the
folders which contain the video files and those of the web directory
and they are all writable to by the user under which apache runs.

I am serving the video file from a local NTFS share which is also
being used a CIFS share.  I read there may be problems with streaming
from CIFS shares that require Enable SendFile Off to be added to
http.conf so I added that to no avail.

Any suggestions on what I'm missing here?
