[FFmpeg-user] FLV(Speex + H.264) --> MP4(AAC + H.264) Converstion

[Leo Papadopoulos]

Dear Group:

I have FLV files that contain Speex Audio and H.264 video that I need to
convert to MP4 with AAC audio and H.264 video.

I used the following command:
ffmpeg -i telecomcto.flv telecomctotest.mp4 -vcodec h264 -acodec aac

Results:
- File plays on my Windows PC but is jittery.
- File plays audio only on my iPad.
- File does not play at all on my Andriod Tablet that has newest Andriod OS.

These errors are possible the problem:
[libspeex @ 0x8b68be0]Missing Speex header, assuming defaults.
[h264 @ 0x8b68650]non-existing SPS 32 referenced in buffering period
[flv @ 0x8b67420]Estimating duration from bitrate, this may be inaccurate

Can anyone offer and suggestions?
