Super, does the job beautifully.
Glad to hear you’ve got it working, so I’ll just make a couple of even
further off topic comments.
A few weeks ago we were talking about HE-AAC and SBR support. Out of
curiosity I looked through descriptions and reviews on Amazon to see if any
satellite receivers supported HE-AAC. Some of the Humax ones do. It seems
from the reviews that some Humax models encrypt their recordings so they can
only be played back on the machine that made them. It sounds as though you
have been lucky with your choice of model.
get_iplayer for some reason uses a different format for ffmpeg options
depending on the value of ! $opt->{ffmpegobsolete}
7027 if ( ! $opt->{ffmpegobsolete} ) {
push @codec_opts, ( '-c:v', 'copy', '-c:a', 'copy' );
} else {
push @codec_opts, ( '-vcodec', 'copy', '-acodec',
'copy' );}
As far as I am aware all the variants Vangelis suggested work.
