Can't play certain kinds of FLV videos

[randian]

I'm using an Intel iMac, 10.6.4, with VLC 1.1. I'm trying to play some FLV files, but only some of them work. Those that don't get a green screen, but audio works regardless. VLC says that the working ones are using the 'On2 VP6.2 Video'. The non-working ones are using 'On2 VP6 A Video'. What's the difference? Is VP6A not supported? Should I tell the webmaster to re-encode his videos? If so, what do I tell him so he doesn't repeat the mistake?

Here's some console output:

I am forced to use "SWF & FLV PLayer" to play these videos.

[Jean-Baptiste Kempf]

Can you share them please?

[randian]

Here's a link to one: http://dl.dropbox.com/u/8711790/Closing%20Checklist.flv. Go ahead and download it.

[Jean-Baptiste Kempf]

Yes, confirmed. This is a bug, because VLC doesn't manage PIX_FMT_YUVA420P
Is ANY player able to play those?

[randian]

Is ANY player able to play those?

SWF & FLV Player does, as does QuickTime Player (via Perian). I'm not sure but I think ffplayer (ffmpeg) might too.

[Jean-Baptiste Kempf]

ffplay doesn't...

[Lotesdelere]

ffplay doesn't...

FFplay does play it for me on Windows.
So does MPC-HC.

[Jean-Baptiste Kempf]

latest ffplay doesn't play it on linux, since they changed the pix_fmt

[Lotesdelere]

latest ffplay doesn't play it on linux, since they changed the pix_fmt

Ah yep, same on Windows with recent versions. I was using a 2.5 months old FFplay.
So, for the record:
ffplay SVN-r23085 11/05/2010 => Fails
ffplay SVN-r22960 25/04/2010 => Works

Indeed, and this was reported upstream.

It will be fixed in future versions of VLC then.

[randian]

It will be fixed in future versions of VLC then.

Yay!

[phippu]

Hello,
has this Problem been fixed yet ? I still have a green Screen playing certain FLV's with VLC ? (Windows Version 1.1.9 The Luggage)

Any Hints how to re-encode this Flash-Movie so it can be played with VLC.

[Jean-Baptiste Kempf]

I think I fixed this for VLC 1.2.x

[hans_moleman]

Jean-Baptiste you're the man.

I had scratchy audio the first 10 seconds of playback with the
"output date isn't PTS date, requesting resampling"
message.

Everything's sweet now after upgrading from 1.1.9 to 1.2.0

Thanks a lot.

[randian]

I think I fixed this for VLC 1.2.x

When is that coming out? I'd sure like to use your fix.

[Jean-Baptiste Kempf]

[randian]

Dang, it appears this fix isn't in VLC 2.0.0 (OSX).

[Jean-Baptiste Kempf]

Really? the same bug with chroma 35?

I'm experiencing this problem on 2.0.5 with certain flv files. I have filed a bug with a sample video: https://trac.videolan.org/vlc/ticket/7994
