[mythtv-users] mythtv-leanfront and DVB-T2 recordings

[John Pilkington]

After my recent post that mentioned not being able to predict whether an 
h264 recording would play to the end in the leanfront, it seemed worth 
trying a modification of my mythTScut script, using its no-cuts option 
and trying to deinterlace.  Changing

" -map 0:0 -c:v copy -map 1:1 -c:a copy "

to

" -vf "bwdif" -c:v libx264 -preset medium -c:a copy "

gave a file that played on beyond the point at which the video had 
previously frozen - but rather slowly, in my case about 6 times real 
time for a BBC1 HD News item.  I used q to quit, rather than waiting for 
ffmpeg to finish. The process also complained several times about 
corrupt video data, so the interlace might not have been the only reason 
for the freeze.  Playback quality in leanfront was fine.

Other filter/preset combinations might give a better balance - or 
perhaps handbrake?
