mencoder - combining flv file without sound - help

[grissom]

Hello

Im trying to combine to flv files using mencoder. As usuall I've some problems to solve ;/, hope you will help me. So scenario is like this: I have mov files, converting into flv file (converted flv files still has sound), so:

ffmpeg -i video_1234_123_1.mov

 Stream #0.0(eng): Video: mjpeg, yuvj420p, 1024x768 [PAR 1:1 DAR 4:3], 7 tbr, 7 tbn, 7 tbc
 Stream #0.1(eng): Audio: pcm_s16be, 44100 Hz, stereo, s16, 1411 kb/s

next converted flv files:

 ffmpeg -i video_1234_123_1.flv

 Stream #0.0: Video: flv, yuv420p, 800x600, 200 kb/s, 25 tbr, 1k tbn, 1k tbc
 Stream #0.1: Audio: adpcm_swf, 44100 Hz, stereo, s16

and then Im using mencoder to combine filev files:

mencoder -forceidx -of lavf -oac copy -ovc copy -o output.flv video_1234_123_1.flv video_1234_123_2.flv

No errors so hard to say whats wrong. You can try avidemux and see if makes any difference.

ANd I would make a flv with h264 video and aac audio instead of the crappy flv codec.
