File size is not an indication of pixel dimensions, it is the bit-rate
which determines file size

Agreed. All HD content available on the main iPlayer service is 1280x720p25.

HOWEVER, the HD programme material available if you have a Sky+HD box 
... is 1920x1080i25 (I think, you get combing artifacts when you hit 
pause but this might also be because the Sky+HD boxes max out at 1080i 
on HDMI).


So, either BBC provides a feed exclusively to Sky's on-demand platform 
just for us lucky Sky customers, or there is another unadvertised 
version feed only available for specific devices or proxied through 
specific gateways. When I realised I Wiresharked some traffic as I 
downloaded a file, it was coming from a CDN. More investigation required.

That would be a very good feature, which I suppose I'm hereby

Re: Why M4a and not mp4?

2012-11-14 Thread Christopher Woods (CM)


Google would be your friend here. M4A and MP4 have the same container 
format.  The M4A extension is just a naming convention for audio-only 
files, a convention to which get_iplayer adheres.  For whatever 
reasons, some players won't recognise the M4A extension, so rename.


Personally I always use the aactomp3 flag in get_iplayer to 
transcode the AAC file as MP3 for a radio programme. No problem 
playing in anything that way.

Re: I haven't been able to download using PID for ages....

2012-09-26 Thread Christopher Woods (CM)

Some interesting comments all, thanks.

The reason I put --pid at the end of my string is partially to stop me 
from forgetting to change it ;-) And I only ever use get_iplayer to grab 
stuff for which I've already found the PID for, I always found its PVR 
features a little cumbersome for what I wanted.


My explicit SWFVfy declaration was after the default player URL was 
removed by the BBC so rtmpdump was having problems with dropped frames 
and corrupt downloads, particularly on the HD content.


I was under the impression get_iplayer still transcoded to MP3? I'm 
using 2.79 on Windows; I remember a lot of discussion a while back about 
the quality of the downloads and people asking how to stop it from 
transcoding. I left it as-is because I remember a few things being 
broken in updates pushed out - but if newer versions have those bugs 
squished and have a newer build of ffmpeg rolled in, I'll certainly give 
that a try. I'm a sucker for metadata. Undoubtedly YAMB is a bit long in 
the tooth now, I've only just got used to some of its UI quirks ;-)

The --swfvfy value is built into get_iplayer.  There is no need to use 
it on a command line unless you know of a case where the built-in 
value no longer works.  Also, you don't need --get if you specify 
--pid. Think of --pid as shortcut to download a specific programme 
when you already know its unique identifier.



a liveradio category result for the pid you enter. My golden rule is to
always have --pid or --url at the very end of the string. Specifying the
10player URL stopped frame drops in videos when rtmpdump couldn't swfvfy
properly.


There is no need to put --url or --pid at the end of your command 
line.  get_iplayer's argument parsing is not sensitive to entry order.



Using --raw obviates the transcoding (yeurgh). use FLVExtract to rip out
AAC from the FLVs and then use YAMB (or MP4Box if you're not lazy like
me) to remux as an M4A and get it seekable. For videos, I just leave as
FLV as MPC can parse and decode them fine natively; when I remuxed as
MP4 I had frame drift for whatever reason... and at that point I was
happy enough anyway with the H.264 FLVs. :-)


To echo SeƱor Guano: get_iplayer does not transcode.  You only need to 
re-mux files yourself if you wish to use a different tool or different 
parameters.  If you prefer to use --raw and stick with FLV files, 
that's fine.  But if you prefer to re-mux files to MP4 format and get 
metadata tags, etc., the combination of get_iplayer and ffmpeg works 
pretty well.


If you're using YAMB and consistently seeing drift in re-muxed video, 
get an up-to-date version of ffmpeg and let get_iplayer re-mux a few 
programmes and then compare the results.  No guarantee it will be 
better, but ffmpeg (as well as MP4Box) has come along a bit since YAMB 
was released a few years ago.

Re: BBC iPlayer introduces Live Restart capability

2012-06-20 Thread Christopher Woods (CM)
This is a very interesting topic, particularly as I've noted that the 
Beeb's been running a (non-advertised) 720p BBC HD stream using chunked 
H.264 for a while. Quality's pretty darned decent, I'd watch it if I 
didn't have a Sky+HD box.


I can't imagine they'd rip and replace their entire infrastructure for 
on-demand, particularly with all the embedded devices they support... If 
anything this means more complexity - chunked HTTP for PC and Mac with 
the latest versions of Flash, progressive streaming for everything else.

Or is it only for live TV?

Will they switch from RTMP to chunked streaming for non live?

As we can keep all the video chunks as we distribute them, we can
offer them to be viewed again later, or even store them more
permanently.

Re: iPad3

2012-06-05 Thread Christopher Woods (CM)
I imagine there isn't and won't be for a while. Apple's policies on what 
apps can do and what they can access is remarkably restrictive. AIUI 
they only permit Objective-C - no scripting in languages Perl - and not 
only that, to easily achieve what get_iplayer does would require 
additional installation of static dependencies which Apple is always 
against. (Never mind the device probably needing to also be rooted!)

First need to extract the aac.
Then edit and save with mp3DirectCut.
And mux the aac back into m4a.
