How to convert mp4 to flv in virtualdub?

[sgbd]

it's possible to do?

thanks.

No. Try instead freemake video converter or xmedia recode.

And remember that flash already supports mp4 with h264 video and aac audio.

I know about it but idk why when i put mp4 files with H.264 codec in flowplayer or JW player it only play when mp4 file is fully loaded, but when i convert it to flv it play while the file is buffering.

I read something about progressive in mp4 files but i don't understand it maybe u could explain it for me.

thanks.

Use mp4 faststart, https://www.videohelp.com/download/mp4%20FastStart.zip . It uses mp4box with the -hint option so the mp4 plays while buffering.

i'll try it.

thx.

i got another question but it's about avidemux, i installed k-lite codecs but in avidemux i can't see H.264 codec in video. i need to install it?

[Baldrick]

I think h264 is called mpeg4 avc in avidemux. It's the same.

[sgbd]

hum, but idk why but in my work i got avidemux and i have H.264 in video.

[sgbd]

what codec equivalent vp6 in avidemux?

I use this excellent easy tool specifically written for this:

Use it for couple of years, back then when videoeditor exporters ignored this issue. You render mp4 with whatever you want and then you run that file through that mp4faststart (it's fast), it moves atom moov to the beginning of that file, that's all.

edit: ok, Baldrick already mentioned mp4faststart
