GiP uses ffmpeg's aac_adtstoasc bitstream filter to remove ADTS
framing when copying the audio stream from .ts files, but more recent
versions of ffmpeg do that automatically for MP4 output format. If you
re-encode the audio as well as the video (probably not necessary),
that won't matter.

Yes. noted OK. :-) Following on from that, though...

How do I find out the command gip sends to ffmpeg to do its default
conversion as things stand? IIRC it has to recontain the content and tweak
the aac format in some way. So I'd need to be able to replilicate what is
needed, plus the spec to tell ffmpeg to fo 50 -> 25fps.

Basically, I'm looking for the quickest and most 'damage free' way to get
the frame rate conversion but still leave the audio and level of picture
detail OK.

Jim

You'll want to use the --raw flag with GiP to avoid remuxing to MP4
and tagging, both of which create a file copy, which would halve the
max size of programmes you could download to ram disk.

Re: no more hslv format ?

2018-04-30 Thread Jim web
I've been discussing the 'loss' of the 1280x720 25fps version with someone
at the BBC.

IIUC this stemmed from 'Red Bee' days of yore, and until recently people at
the BBC had thought they had stopped it long ago. Someone apparently
noticed recently that it was still available. And then actually disabled
it. Hence the mysterious recent ending of its availablity.

I have made the point that the 1280x720 25fps version is useful for people
with a content 'cap' problem, etc, so will be missed because the 50fps
version means somewhat bigger files and/or stream rates. But I doubt this
will cause a rethink.

That leaves me currently in a dither between fetching the 1280x720 50fps
and running it though a frame rare conversion or giving up and making do
with the 960x540 version(s). It has also set me wondering about arranging
for gip to fetch to ram storage and then convert that into a file on my
main disc. (The machine I use does have 8GB of ram, mostly free when I am
fetching things in the morning.) Anyone have experience of doing this, file
by file?

What I have in mind is a process of

1) Use gip to get a 50fps file saved to ram.

2) Get ffmpeg to convert that into a 25fps version on main disc.

3) Delete the file in ram

4) Loop back to (1) for the next file on the list.

I can avoid a 'cap' as I do all the fetching before the 9am start of our
'metered' period. The above should reduce wear and tear on my main disc (an
SSD). But I don't know how feasible it might be. Comments?...

Jim
