iFP 790 "Not Supported Ogg Format" error?

[jdcpar5]

I just purchased an iFP 790, loaded up a bunch of ogg files, tried to play them and got an error: "Not Supported Ogg Format" and they wouldn't play! Weird, because they play in my HP140.

Does anyone know if there's a limit to the bitrate that's supported by the iFP 790?

TIA

It's weird, on my 890 I have random un-supported errors. Basically I'll rip a whole CD and atleast one of them comes out "bad", although they play on the PC. Using EAC > oggenc2.3-1.1.0P4MOD @ -q 4 --advanced-encode-option impulse_trigger_prof ile=3 --advanced-encode-option impulse_noisetune=-15

I'm new to OGG so I dunno if I'm doing something wrong either.

The average bitrate for an ogg file must be no lower than 96. If it is lower than that, you will get the error message listed.

is there any way that the setting could be changed?

[vinnie97]

encoder setting or player setting? The former, yes, you can limit bandwidth to 96 and above by using specific command line options when making the encodes (a pain unless you automate it with a .bat file or a similar script...I think some of the encoding software can also save command lines for you, however).

If you meant changing the player, no, it is a limitation set by Iriver due to increased power consumption and/or excessive processing load requirements of the embedded Iriver ogg decoder.

I've been vainly waiting for this limit to be lifted for the imp-350 ever since they added ogg support, and I've just about given up.

The iFP-790 manual says 96-225 Kbps, but can anyone provide a good Ogg rate that works all the time?
I encoded an album, all with the same rate (100 or so) and some songs play, some give the "UNSUPPORTED" error. For now I've given up on OGG format and using MP3.
BTW, two e-mails that I sent iRiver support were never answered...

encode ogg vorbis using Q4 or Q5 and they should 99.95% of the time stay withiin the supported bandwidth of the ifp productline.

Sooner of later (I hope) iRiver will get around to supporting the entire ogg codec but as it stands now they do not.

Also, as a sidebar, there is effort underway to improve ogg vorbis as ir relates to battery consumpsion in portable DAP's. Visit HA Forums to keep abreast. Caution: if you post there YBHYST. Or they will beat you to death.

Thanks, I'll try the Q4/Q5. Just a quick follow-up - what is YBHYST?

You'd Better Have Your S--- Together is my guess.

Incidentally, I find that Q3.5 is good enough for the noisy environments where I use my 799, rarely results in too low a bitrate, and saves some space.

Hi, I have just bought an ifp-895 and was disapointed to see that some ogg files does not play when the average bitrate is lower than 96.
But I have found a workaround, try the following:
type rejected.ogg > good.ogg
type rejected.ogg >> good.ogg
Now upload the good.ogg file to your player, and it will work. The problem is of course that you are using 2x memory space.
In a general way the rules are:
- The second stream has to have the same streamID, otherwise the player will reset.
Hope it will help some of you.
Of course the best would be to have a new firmware from IRIVER, without this limit, or at least a reason to not remove this limit.
Bye bye ...

I also like OGG, but besides the bitrate limit, I noticed that my iFP-799 plays OGG songs at a lower volume that MP3 and WMA.

Initially I thought that this was because my OGGs weren't normalized, but then I performed a test. From a normalized WAV, I created an OGG and an MP3. When playing both files on the iFP, the MP3 clearly sounded louder.

Also when switching between OGG tracks there is a ticking noise, which doesn't happen with MP3 or WMA.

So I'm suspecting that the OGG decoder in the iFPs is really limited and it looks like to be in a very early stage of development.

I really hope that iRiver keeps improving the OGG support in the next firmware releases...

FYI, also make sure that your not using .ogg that are recorded at 48kHz, (for all those Sound Blaster junkies out there, E-nit) coz u know say them don't work them, only 44kHz works at the aforementioned kbps settings..

Ogg supports VBR encoding and they now encourage you to encode with a quality setting rather than specifying the actual bitrate. There /is/ a way to encode vbr oggs with any quality you want while also specifying the minimum and maximum bitrates like this:
oggenc -q 5 -m 96 -M 225

Hello, I am currently running a T10 *woot woot* and I have the same OGG incompatability problem.

When you access your device via Windows Explorer (Do not use Windows Media Player... it is quite honestly a piece of **** , thanks Bill) I assume you will have folders named "Data" and "Media".

In "Media" on my t10 w/ latest (1.63) firmware I have the folders: "RECORD", "VOICE", "Service", and some random XML file o_O (I imagine some of you have a Music folder - more on that to come ). So I decided to cause mayhem and anarchy and I deleted ALL OF THEM! MWAHAHA... k back to topic... The iRiver automatically re-created these folders -_-". I was thwarted.

So... then I decided to try the "Data" folder I referenced previously. I stuck a 43 Kb/s bitrate OGG in there, booted my little wonder up and.... MUSIC!! wonderful OGG Vorbis-encoded tunes spewed forth like frothing magic. I did an Irish jig and settled down to play with my device a little more (the T10, that is... O_O"). I made a Music folder in the data folder for my... music...*redundant comments ftl! >_<*.

ARGH! --> You need to create these folders outside of the device's window and drag and drop them since the T10, at least, lacks the ability to move files and folders from one section of memory to another.

Upon booting up again the device defaulted to my created Music folder and it's contents.

NOTES: I have not tried all bitrates, but I know for sure 96 kb/s is NOT the limit ^^. GL, HF, & STAY SANE,

Silent

EDIT: I have just successfully played a variable bitrate 14kb/s @ 8000Hz... 4:50 song in 486Kb ^^ (Didn't sound great - quality relative to an old-fashioned record player, but that's not the moral of the story :P)

I had T10 and it played ANY OGG file I prepared ;] T10 has no problems with OGG Vorbis at all
