Stream interruptions - I/O error: Write end dead

I'm trying to view a sopcast stream on a Samsung D-series TV (F1 motorsports on hahasports.com with the hahasport plugin) and I always get problems with the feed interrupting and skipping to the next feed. It's rare to get more than 10 minutes worth of feed without it crapping out.
Errors are below. I'll include the ffmpeg command from a litte earlier in the log. This is with Christian's build (qpkg) of 1.0.1 on Qnap x86 with included ffmpeg (command line opts hard-coded the path to the correct ffmpeg).
This isn't a new issue - I've suffered for a year or so including with v0.6x as well. Just would really like to get a handle on it!

[edit] no filesystems appear to be filling up on the Qnap

Ah - this could be the same as other instances of the ffmpeg 'unknown error'. Here's what happens from the command line.

rtmp://213.163.76.72/pull?testkey=78b6a ... 236d0f305f: Unknown error occurred

When running the ffmpeg command from the command line ( piping output to /dev/null) I get the 'unknown error' immediately & ffmpeg quits with status code 1. Streaming to the TV usually works for a few minutes though so the 'unknown error' may be a red herring.

[zip]

wrap the URL in quotes, like:

  Code:

ffmpeg -fflags +genpts -i "rtmp://213.163.76.72/pull?testkey=78b6a ... 236d0f305f swfUrl=http://files.leton.tv/player.swf pageUrl=files.leton.tv playpath=f1grand2" -y -copyts -c:v copy -vbsf h264_mp4toannexb -c:a ac3 -b:a 32k -ar 48000 -ac 2 -map 0:0 -map 0:1 -sn -f mpegts pipe: >/dev/null

Note the URL is pasted incorrectly (with ....), you'll have to fix it on your command line

Thanks! Will give it a try.
