[MPlayer-dev-eng] A filter for mplayer could help encoding MythTV recordings faster

[VJ]

Hi,
   I use mencoder for encoding the mythtv recordings. For it I have my own
scripts to invoke mythtranscode (which writes data to fifo and mencoder
reads it) and mencoder to compress the programs to mpeg (vcd) or avi
(xvid). I need this setup because I remove the commercials manually and
mythtranscode+mencoder setup finally gives me encoded file without any
commercials.

   But I have seen that if I use mencoder on a file (same .nuv file) it
gives me fps of about 33-40(but then I lose commercial skipping), but if I
go via my present setup, I get fps of about 20-22.

   If only somebody could write a filter for mencoder to skip frames then
mythtranscode will not be needed anymore. e.g. -vop
skip=0-1200,1800-2000 could be added to command line params of mencoder to
skip desired frames and thse can be obtained from cutlist in
database.

    I know I have taken this from transcode application, but I did not
like it because it skipped frames which caused jerkyness in encoded files.

   I will try looking into the code of filters in mplayer/mencoder thus
week end but I am not that good in coding for multimedia applications.
