[SOLVED] flv to mp4 using ffmpeg cli on debian

Issue

I'm trying to convert this flv file into .mp4 using ffmpeg on debian.

• Stream 0 Type: Video Codec: Flash Video (FLV1) Resolution: 640x480 Frame rate: 1000 Decoded format: Planar 4:2:0 YUV

  Stream 1 Type: Audio Codec: NellyMoser ASAO (NELL) Channels: Mono Sample rate: 22050 Hz Bits per sample: 32

I'm currently using this simple command...

sudo avconv -i videoStream_1424268207948_854.flv videoStream_1424268207948_854.mp4

These are the warnings I receive:

• [flv @ 0x14fab20] Estimating duration from bitrate, this may be inaccurate
• [libx264 @ 0x14fdaa0] MB rate (1200000) > level limit (983040)
• Multiple frames in a packet from stream 0
• [flv @ 0x14fca60] Bad picture start code
• [flv @ 0x14fca60] header damaged
• Error while decoding stream #0:0

... and it results in messed up video and audio.

Can anyone help with some parameters?

Solution

It worked for me using ffmpeg version 2.5.4. Try upgrading avconv, or switching to ffmpeg.
