FLV's new Mp4 support...

[doctorm]

I'm starting to see Flash video files containing AVC video and AAC audio.
Although that's really a nice upgrade, Flash players are garbage at decoding.

While VLC can handle it (poorly), FLVSplitter is completely lost (and unfortunately that means no MPC, CoreAVC, ffdshow, etc.).

I thought maybe demuxing and putting in it in a Matroska container would be better, but FLV Extract (and avidemux) are also unable to handle the newer FLV format.

As far as I can tell we're pretty much stuck with VLC (which is meh) or Flash Player (which is a bit better, if less friendly).

Does anyone know if there are projects underway to support the newer Flash formats?

[Baldrick]

Aren't they standard mp4? The mp4(h264,aac) I make for flash works perfectly fine in mpc(with haali media splitter and ffdshow) and mpchc.

[doctorm]

Hmm. I tried renaming to mp4 and no luck.

I can't import it into MKVMerge which says:
"The file is an unsupported container format (Macromedia Flash Video (FLV))"

Re-installed the latest Haali Spliter and have CoreAVC and ffdshow (for AAC).

Maybe it's just the specific video I'm looking at but:

you can try mp4box (yamb is the gui) to extract the streams

did you try mpc with ffdshow (with h264 and aac decoding enabled set to libavcodec), with haali media splitter ?

the new(well not so new by now) adobe flash player can play mp4 files(avc+aac) so i really dont get why they're putting avc+aac in FLV, you can play avc+aac in FLV or MP4 by using VLC, MPLAYER/MPUI, SMPLAYER

About flash players being garbage... i didnt have any problems decoding streaming mp4 or flv, the adobe flash player uses the "well established" mainconcept decoder.

Yes.

It may be established, but it's still inefficient.

Try FFmpeg (some latest SVN build)...?

ffmpeg -i name_file.flv -vcodec copy -acodec copy name_file.mp4

If not work, what's error message?

[ricardouk]

It may be established, but it's still inefficient.

Like i said before since version 9....(something) i dont have any problem decoding/streaming mp4(aac+avc) either in window mode or fullscreen on a P4 2.6 so i call it efficient(to me at least), try remuxing the streams into mp4 like previous poster sugested.

For offline viewing ffdshow+MPC have worked perfectly to watch avc for me

[Placio74]

Remuxing used FFmpeg can be work for some FLV's with AVC/AAC, but for some other not (yet).

Problematic: "could not find codec parameters".

AVC in FLV? Check sample files.

FLV Splitter not (yet) support FLV with AVC/AAC.

Of course these sample files can play in Adobe Media Player or XeMoviePlayer and other based on Adobe Flash components.

[doctorm]

Right now it's more the mystery of this @$!$# thing that has me going more than any real need to remux.
I'm starting wonder how it was originally created.



A 2kb empty MP4 file was created.

I only tried the first clip since there is a download limit but this player played it fine. It looks like an updated version of FLV Player 2.0...

http://applian.com/flvplayer/

would not play in Elosoft or FLV Player 2.0.

Where can you get the standalone Adobe player for Windows (not the browser plugin)? I used to have it a couple of years ago but don't have it anymore. Can't seem to find a download anywhere.

Ehm... from FAQ:

What (thirdparty) technologies does FLV Player use?
FLV Player uses Adobe Flash Player, ASAP Framework and FFF Harmony font.

Adobe Media Player and XeMoviePlayer?
Both based on Adobe Air enviroment (installed Adobe Air is required).

DarrellS,

I think this is the last version of the standalone flash player that was made available by Adobe:

https://forum.videohelp.com/topic345926.html#1812036

It's still up, I just checked the link. I don't think it works with flv videos, though, just .swf and maybe some of the earlier .flv flash files.

[DarrellS]

I downloaded the file but it would not install.

EDIT: I guess it did install since my swf files turned to Adobe icons and play in Adobe 9 player but it's not the H264 HD player that I had before since it doesn't play mp4.
