Green Screen on playing flv in VLC 2.1.0

[siddharth99105]

Hi,

I've been trying to play some .flv files in VLC 2.1.0 (OpenSuSe and Windows 32 bit). In some I see a green screen and hear audio, in some I can see only the green screen. I read across many topic and I know its a codec issue, updated VLC to latest version and still it continues.

VLC does not support YUVA with subsampled chroma planes. You should file an enhancement request ticket on trac.

[siddharth99105]

Created an enhancement ticket on trac
https://trac.videolan.org/vlc/ticket/9837#ticket

[beevlor]

The enhancement ticket on trac shows a status of Closed with a resolution of Fixed, with a description of "As of release 2.1.0, VLC does not support YUVA with subsampled chroma planes."

However, I'm still unable to open the sample file included in the enhancement request (as well as my own flv's having this green screen problem). I tested using VLC 2.1.1 and VLC 2.1.2.

Was this REALLY fixed or is it just being ignored or deemed not important enough to keep the ticket open? I love VLC, but hate that I have to use something like Media Player Classic for a small percentage of .FLV files.

[Rémi Denis-Courmont]

Yes, this is a new feature in VLC 2.2.x.
