[FFmpeg-user] FLV Video not Playing Smoothly

[NeonFlash]

Hi,

Please find more details below:

Streaming Video was captured using: Stream Transport software.

Output video format: FLV
Player used to play the video: VLC Media Player

Since the video did not play smoothly, I tried to troubleshoot by viewing the information with ffmpeg.

So, here is the complete output when I check this FLV file with ffmpeg:

ffmpeg.exe -i tofix.flv

tofix.flv (This is the FLV file which is not playing smoothly)

complete output here:

The video was not captured using ffmpeg and not decoded/encoded either. However, I thought ffmpeg could be used for the purpose of troubleshooting here. And once the problem is identified, I could use ffmpeg to fix the video as well?

Thanks.

You didn't mention what player you're using. What about ffplay?
