[theora] Ogv file only plays in VLC / Can't be used by most tools.

Hi,

I'm new here - thanks for having me. (Sorry if I'm in the wrong place or
a noob.)

I downloaded the Theora encoder sample (ver 1.1.1), modified it to encode a
sequence of bitmaps, and created an OGV file.

The OGV file plays fine in the latest VLC (1.0.5), but I can't do much else
with it:

I tried uploading to YouTube, and the video just comes out really corrupt: 
http://www.youtube.com/watch?v=sHaMG6mcWu0
I tried using ffmpeg to convert to another format, but it gives errors (listed
below).
I tried using MEncoder264 and it failed too. The log is below the FFmpeg log. A
potentially useful line of the log is: "Theora header parsing failed:
-23"
I also tried using VLC to convert, but it created a zero sized file too.

It seems like the OGV file is bad in some way, but VLC is somehow
'luckily' able to play it.

Does anyone have any suggestions on what might be going on, or how to further
diagnose the problem?

I'd like to have a 'more robust' OGV file, which I can easily upload
to YouTube or convert to other formats.

In case anyone want's to inspect the OGV file, I've uploaded it here:

Thanks very much for any help,
Mark.

I downloaded your OGV file, and it played properly in Totem 2.28.2.

You could also use ffmpeg2theora for that use, it might be easier.

Youtube transcodes the video with an old version of ffmpeg, which does
not work with some features of the Theora bitstream, which were not yet
used by the previous libtheora encoder, but which are used by 1.1.1.

Same program as Youtube, though a newer ffmpeg might work.

Likely the file is alright.

You could use an older version of libtheora, though you won't have the
encoder improvements in quality and bitrate. Or moan to Youtube to
update their buggy toolchain.

That's a... HTML file... with a lot of Javascript.
Maybe it links to a video, though, I haven't searched inside.

[theora] Ogv file only plays in VLC / Can't be used by most tools.

Thank you all for your helpful responses.

I got the latest ffmepg (from http://ffmpeg.arrozcru.org/autobuilds/) and it
converts my file to mpeg fine. This gives me the workaround I needed. Thanks!


I used VLC to convert to 264 format and mpeg4 format. (To do so, choose
'Media -> Convert / Save'.)  Perhaps it uses a different decoder for
playback than conversion?

Also my usage case is more complicated than encoding bitmaps, I was just using
that as an intermediate step.

Thanks again,
Mark.

YouTube uses an older, buggy version of ffmpeg to handle video, and it
can't read Theora properly.  Until recently, ffmpeg just treated
Theora as if it was still VP3, so it can't actually handle real Theora
files.

This was just fixed a few months ago, but Google/Youtube are still
using the broken version.

Probably the same problem unless you're sure you have a recent build.

THis also uses ffmpeg to decode theora.

That's more interesting.  What did you try to convert it to?

'luckily'

You could send a snippet of the file and I'll inspect it.  it's
possible something did go wrong with the modifications to
encoder_example.

BTW, png2theora will make an OGV out of a directory of .PNG files.
