This release fixes a large number of importing bugs found in 1.2.1,
including crashes, and supports Matroska files created by mkvmerge

versions of mkvtoolnix. [r1317, r1334]
- Added FFv1 lossless video support. [r1363] (#407)
- Added an internal decoder for Theora. [r1379] (#499)
- The readme and license files are now included in the component
bundle. [r1309]
Fixes:
- Fixed MKV files with video glitches due to zero-length frame
durations. [r1364] (#502)
- Fixed audio sync in many FLV videos. [r1383] (1.2 regression) (#543)
- Fixed possible crashes in MKV reading. [r1332, r1392] (#223)
- Fixed several possible crashes/hangs in subtitle parsing. [r1327,
r1331, r1339, r1376] (#515, #521)
- Worked around Apple's incorrect channel layout in .MP4 containers.
[A52Codec r84]
SSA:
- Fixed several correctness errors. [r1307, r1308, r1365]
- Improved rendering of semitransparent text styles. [r1328]
Notes:
- The next planned version will remove support for PowerPC and Mac OS
X versions prior to 10.6. Maintenance updates may be provided if
necessary.

Testing the areas mentioned in the changes would be especially
appreciated.

 If no one reports any problems by Monday, we'll likely make this the final. So definitely test as soon as possible.

Also, please do not post this version to any software trackers.

Hi,
I tested out the webm playback on OS X Version 10.6.6. Tried
QuickTime and NicePlayer. Getting filetype not recognized. This is
not something surprising as 10.6 has been giving me similar problems
originally with mkv. Any thoughts?
So I fidgeted a bit and found that if I drop files onto the nice
player icon I'm getting playback. Nice job. Is the intent to support
OS X 10.5 but not 10.6? I know registering new file types in Mac has
been a thorn in my side in the past.

I've noticed some syncing issues with sound. I tried a few different
files, and one thing I noticed was that sound would sometimes cut
out. This happened in clips with altref frames (don't know if that
makes any difference). I was also noticing some audio sync problems
in other files.

I browsed through perian source a bit and was wondering if webm
playback was done through the matroska implementation in code you have
or if you are using ffmpeg wrappers?

Try opening the .webm file using "Perian - Open in QuickTime Player".
10.6 is supposed to work but the mechanism for registering new file
types doesn't actually work half the time.

Can you link these files?

I wouldn't be surprised if altref needed some work.

WebM files are Matroska files, so it uses the existing import code.

Yeah, I gave it a try and got a popup.
The document
** cold not be opened. QuickTime Player cannot open files of this
type.

Hmm.. I'm not sure if I can link those specific files. Let me play
around with a few others and see if I can replicate it with something
else.

Okay, makes sense. So should I expect a similar long preload behavior
with webm files?

Have you found some yet? I ran through the test vectors and haven't
seen any problems compared to ffplay.
(Two of the samples, with one frame in the file, don't import in
1.2.2b1 - I'll take a look at that but it's unrelated.)

Yeah, that's not something we can fix with a code change. What we
_can_ do is cache the file after the first time it's opened.
