Comment (by Cigaes):

 I am a bit confused about the way you gave your results. Let me sum up,
 and correct me if I am wrong.

 1. {{{./ffmpeg_g -loglevel 99 -i /dev/dvb/adapter0/dvr0 -f null a.flv}}}
 -> runs correctly past the usual problem, and you have to stop it

 2. {{{./ffmpeg_g -loglevel 99 -i /dev/dvb/adapter0/dvr0 -s 540x432
 -filter:v yadif -b:v 1200k -bufsize 400000k -r 18 -ar 22050 -ab 32000 -f
 flv a.flv}}}
 -> stops almost immediately.

 3. {{{./ffmpeg_g -loglevel 99 -i ~/sample.ts -s 540x432 -filter:v yadif
 -b:v 1200k -bufsize 400000k -r 18 -ar 220050 -ab 32000 -f flv a.flv}}}
 -> works to the end of the file.

 Is that so?

 The principle of these tests is to find the smallest change in the command
 line that causes a different behaviour. In that particular case, if 1
 works and 2 does not, you need to remove elements from 2 until it starts
 working again. The first elements to eliminate are {{{-s}}} and {{{-vf}}}.
