MP4 (or any video) to FLV conversion using mencoder

[fireserphant]

I'm trying to convert an .mp4 file into an .flv file and am having some success using mencoder. The .flv file I create opens just fine in VLC, but my ultimate goal is to embed it into a .swf player embedded into a webpage.

I've tried using some of the .swf .flv players and they don't play my converted files. I'm not sure why...anyone else have any luck??



mencoder legoshay.mpeg -ffourcc FLV1 -oac lavc -ovc lavc -lavcopts vcodec=flv:acodec=mp3 -o sample.flv

what swf flv players have you tried?

[fireserphant]

I've tried using flash_flv, flvplayer, and a friend of mine tried importing it into Adobe Flash and it said that it was an invalid file.

The flv players I tried are attached with a sample of how to use them in a webpage.

Could you also post a short flv example?

I need somethng that is free and command-line based. Plus, this one is very similar to one of the players that I posted (the controls look the exact same).

Any other suggestions?

I can't get it to work with my free flash players either.

Maybe try use ffmpeg instead of mencoder.

tried it then...
Similar to what you've tested and were happy to use but not good enough?

You've not created an flv file but an avi.
try:
mencoder legoshay.mpeg -o sample.flv -ffourcc FLV1 -of lavf -oac lavc -ovc lavc -lavcopts vcodec=flv:acodec=mp3 -lavfopts i_certify_that_my_video_stream_does_not_use_b_fram es

it's also better to use mp3lame for audio encoding rather than lavc

It's not Flash Video - it AVI container.


Example syntax for MEncoder:

mencoder.exe -ofps 25 input_file.avi -of lavf -lavfopts i_certify_that_my_video_stream_does_not_use_b_fram es:format=flv -ovc lavc -lavcopts vcodec=flv:autoaspect:vbitrate=500:vqmin=2:vqmax=3 1:vme=5:mbd=1ubq=5:keyint=250 -af resample=22050:0:0,channels=2 -oac mp3lame -lameopts vbr=2:q=6:aq=2:highpassfreq=-1:lowpassfreq=-1 -o output_file.flv

Example syntax for FFmpeg:

ffmpeg.exe -i input_file.avi -vcodec flv -me full -me_range 16 -mbd 1 -qmin 2 -qmax 31 -b 500000 -r 25 -s 320x240 -refs 5 -acodec mp3 -ar 22050 -ac 2 -ab 128 ouput_file.flv

And very simple:

ffmpeg.exe -i input_file.avi output_file.flv
