My ultimate goal is to record a show, then export that show to a
secondary player friendly format automatically. My current approach
is to have a User Job process the recording (just to keep it all in
mythtv). Using nuvexport I can successfully export to my formats of
choice (psp and xvid) but am trying to introduce more automation.
ATTEMPT #1: nuvexport cli only
How would I go about building a command for nuvexport? I'm thinking
it would look something like this:
nuvexport --infile=%FILE% --confirm --cutlist --path=/myth/nuvexport/nuv2psp --nice=19 --mode=psp --deinterlace --noise_reduction +--crop
Also, how can I keep the gui from blowing up
/var/log/mythtv/mythbackend.log?
ATTEMPT #2: ffmpeg
How would I go about building the command for ffmpeg? I think
maybe:
ffmpeg -y -i INFILE -bitexact -f psp -s 320x240 -r 29.97 -b 768 -acodec aac -ac 2 -ar 24000 -ab 32 M4V10005.MP4
I haven't tried the ffmpeg approach yet as I'm not sure how to pass
variables to the commmand line. These specifically:
INFILE
Show title
Episode title
This way my file could be named "Show title" - "Episode title".MP4
instead of PSP's special format. (I can name it M4V10005 later on,
just need to be able to tell what's what with many in a folder).
Thanks to Byron Poland for getting me started with the ffmpeg command
