RB won't play certain ogg vorbis files

<< < (2/2)

Julian67:
Or use ffmpeg to remux (copy the audio, no transcoding):


--- Code: ---ffmpeg -i OrbitMix1.ogg -acodec copy -vn OrbitMix1_corrected.ogg
--- End code ---

-vn means no video.
-acodec copy means copy the audio unchanged.

This will leave you with an ordinary Ogg Vorbis audio file, playable by any app/device which supports Ogg Vorbis audio.

I looked into the oggz-rip program, but what I saw made it look like it was for Linux.  And I never actually came across a link to download it.  BUT, the ffmpeg thing completely worked, thanks!  What do you use to 'examine' a file to see that it has 2 streams instead of being a conventional audio-only ogg file?

I used a tool called ogginfo that happens to be installed on my laptop, but I suspect ffprobe (from ffmpeg) will also tell you

The rockbox sim also reports streams it cannot parse.

As you have ffmpeg installed then you can just use that to inspect the file without performing any action:


--- Code: ---ffmpeg -i OrbitMix1.ogg

......blah...blah...acres of verbose ffmpeg output ....

  libpostproc  51.  2. 0 / 51.  2. 0
Input #0, ogg, from 'OrbitMix1.ogg':

    Stream #0.1: Audio: vorbis, 44100 Hz, stereo, s16, 96 kb/s

At least one output file must be specified

--- End code ---

and you can see there is the video stream as stream 0.0 and the audio stream at 0.1
The same can also be done by:

ffprobe OrbitMix1.ogg
or
ffprobe -show_streams OrbitMix1.ogg

ffprobe is part of ffmpeg so you should have it available.
