Re: [SlimDevices: Plugins] BBC iPlayer AAC streams
amcluesent;437335 Wrote: is there any easy way to stream the AAC live radio feed into Squeezecenter... Nope. This is bleeding edge stuff, hence I posted to see if the crew who did AlienBBC could make the last jump from mplayer into SqueezeCenter. I've got an experimental get_iplayer PVR Manager proxy released which can do this now. It proxies the high-quality AAC RTMP stream into WAV over HTTP then auto generates OPML playlists. Also works for BBC listen again. Cannot yet get FLAC streaming working but WAV is the same quality of course.

Re: [SlimDevices: Plugins] Recording of Radio Stations
(note: shameless plug - I'm the get_iplayer author). get_iplayer also can get programmes automatically using it's PVR functionality. Basically you just setup a PVR entry in get_iplayer based on programme name and it will download it, transcode it if necessary (from real, flv or wav etc to mp3), id3 tag it, and save in file directory of your choice ready for listening. It will even email you when a new prog is downloaded if you want (on Linux at least). You just need to do something like: get_iplayer --type=radio 'Chris Moyles' --amode iphone Then add it to the PVR as follows: get_iplayer --type=radio 'Chris Moyles' --amode iphone --pvr-add 'my_chris_moyles_search' The --amode option basically lists which downloads methods to try (default is: iphone, flashaudio, realaudio). The first two are native high quality mp3. The realaudio mode is of pretty poor quality. You then just add '/path/to/get_iplayer --pvr' to your cron to run, say, hourly.

However yo keep users happy - firmware support would probably have to support AAC and AACplus v1 and AACplus v2. * I think the Blogs referred to support AACplus in addition to MP3 not instead of MP3. * BBC strategy seems to be a bit flexible or not fully detailed in the blogs. A few months ago the only MP3 planned seemed to be secure (over Flash) and now these unsecured MP3 streams are available in addition to the secure MP3 streams. The MP3-over-RTMP (in flash) was the first step of getting Listen Again on the iPlayer. They plan to migrate to AAC+ (possibly starting from this month) because it is already supported by flash player and is more bandwidth efficient / higher quality. The mp3 streams being used in the BBCiPlayer plugin were intended for the Apple iPhone which does(will) not support abobe flash player (The plugin has to fake an iPhone user-agent to get these mp3 streams). It was my suggestion that these streams were just a different transport mechanism using the same files served over RTMP/flash because of the similarity of the bitrates. It would seem from all the blog and forum stuff I've read that the MP3 streams will be dropped once they are happy with AAC+ and I reckon that the mp3 will then cease for the iPhone streams because there is no logical reason to keep mp3 for the iPhone when the more-apple-friendly AAC+ files will be available. They don't support any more devices with Listen Again mp3-over-http AFAIK - just the iPhone. So in future, if this transition happens to AAC+, transcoding (e.g. mplayer) will be required unless the SB can get AAC+ suport in the firmware.

Triode;347173 Wrote: Lets hope the beeb continues with support for the mp3 streams for a while or moves to a codec which we can also support via transcoding. To me the main aim is to get somethign with better quality than the real streams. I am dubious the aac+ means they can reduce the bitrate too much. The 192k mp3 streams for radio 3 sound relatively good. The 128k mp3 streams for other stations are ok, but not great. I totally agree - quality is the issue. If I'm not mistaken, the mp3 streams (RTMP/Flash and iPhone) we have today are re-transcoded from the DAB/satellite mp2 broadcast streams (eek). The new AAC+ ones will use pre-transcoded streams which will significantly improve the quality. Also AAC+ is really quite a lot better at the same or lower bitrate in blind listening tests compared to the well-aged mp3 algorithm and pshcho-acoustic models.

Just in case you hadn't seen it, I posted on this thread: http://forums.slimdevices.com/showthread.php?t=53171 regarding a way to directly get the mp3 streams from iPlayer.

[SlimDevices: Plugins] Alien BBC suggestions - better iPlayer Listen Again feeds and bitrates
Hi, I've been using Alien BBC for years now - good work - it's really useful! I've have developed the get_iplayer perl software (used for downloading BBC iPlayer programmes) which also does very similar things to Alien. Firstly, I've noticed that there is a bit of screen scraping in the Alient code (e.g. Plugins/Alien/Parsers/iPlayerParser.pm ) that possibly could be avoided: After some research in to BBC feeds I found that it is possible to get an entire list of programmes for a radio channel using the following XML feed from the BBC: http://feeds.bbc.co.uk/iplayer/channel/list/limit/400 Where channel is one of: bbc_1xtra, bbc_radio_one, bbc_radio_two, bbc_radio_three, bbc_radio_four, bbc_radio_five_live, bbc_radio_five_live_sports_extra, bbc_6music, bbc_7, bbc_asian_network, bbc_radio_foyle, bbc_radio_scotland, bbc_radio_ulster, bbc_radio_wales, or bbc_world_service. These feeds are used by the iPlayer web site and I have just tweaked them a little to give a full channel listing. Secondly, for podcasts, it is possible to get a full list of podcasts from either of the following (saves having to specify a list of channels in the Alien perl code): OPML: http://www.bbc.co.uk/radio/opml/bbc_podcast_opml.xml XML: http://downloads.bbc.co.uk/podcasts/ppg.xml Thirdly, it has recently (this week) been discovered that you can now download/stream the BBC listen again stereo content in MP3 streams up to 192kbps (many are 128kbps and a few in 80kbps/mono). This is *significantly better* than the 64kbps real audio streams we've been limited to in the past. The method used for this simulates an iPhone but is really not that difficult to implement in perl. I have already coded this in perl for get_iplayer and it works like a dream :-) I've documented the Mp3 BBC listen again radio download method on the Beebhack wiki for those people who may want to look at this: http://beebhack.wikia.com/wiki/IPlayer_Radio#iPlayer_MP3_Radio_Streams My (bad perl code but lots of comments) get_iplayer software which has implemented this can be found at http://linuxcentre.net - Phil Lewis -- linuxcentre linuxcentre's Profile: http://forums.slimdevices.com/member.php?userid=20244 View this thread: http://forums.slimdevices.com/showthread.php?t=53171 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/plugins
Re: [SlimDevices: Plugins] Alien BBC suggestions - better iPlayer Listen Again feeds and bitrates
@bpa, Yes, the non-AOD stations aren't in iPlayer yet. I think the BBC are finding the AOD-iPlayer migration a bit time consuming from the posts on the BBC Radio Labs blogs. The iPhone Listen again streams are indeed UK only :-| Hopefully this may change over time. Not sure why they would need to limit the MP3 Radio progs as such compared to the RealAudio ones. @Triode, Note that the BBC cookie white-listing based on those BBC web bugs in my code is no longer required. Just remember to keep the stream chunks 20MB. -- linuxcentre linuxcentre's Profile: http://forums.slimdevices.com/member.php?userid=20244 View this thread: http://forums.slimdevices.com/showthread.php?t=53171 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/plugins
