Getting error message when attempting to copy streams

[bf4648]

I'm using a much bigger file with the file name of 2011-03-31-23-00-00~23-15-00-channel1.mp4 but I can't upload it because it is 95.4 MB so I have therefore attached a sample of the video called "sample". I'm trying to load the .mp4 file into ffmpeg at the -ss of 1.16 and -t 6.74 and copy the streams using -acodec copy -vcodec copy but I'm getting an error message of "Seems stream 0 codec frame rate differs from container frame rate: 60.00 (60/1) -> 30.00 (30/1)" and the video is all fuzzy (although I can make out some things in the video).

Here's my command line in Ubuntu 10.04:

~/Desktop$ /usr/bin/ffmpeg -ss 1.16 -t 6.74 -i 2011-03-31-23-00-00~23-15-00-channel1.mp4 -acodec copy -vcodec copy /tmp/clip_id_fcbf7154-22d2-11e1-bb69-000c290d9e26_offset_1.16_length_6.74_2011-03-31-23-00-00~23-15-00-channel1.mp4

I'd just like to copy the audio and video streams so I won't have to re-encode and therefore take time to do that. Is that possible or is this a bug? Attached is my sample...

This is very old and unsupported, please test current git head (as you did before).

Yup, I was afraid of that..I just installed ffmpeg using sudo apt-get install ffmpeg...alright, here's my output using the current git head:

If I submit the following command line without the -ss & -t options, it works & makes an exact copy w/ out the "fuzzyness":

ffmpeg -i 2011-03-31-23-00-00~23-15-00-channel1.mp4 -acodec copy -vcodec copy clip_id_fcbf7154-22d2-11e1-bb69-000c290d9e26_offset_1.16_length_6.74_2011-03-31-23-00-00~23-15-00-channel1.mp4

[Carl Eugen Hoyos]

Is there still a problem you want to report?

[bf4648]

Cehoyos,

It looks like it's my version of VLC that is causing the problem. I can play the newly clipped file on my mac with out the fuzzyness. My mac is running VLC Version 1.1.12 The Luggage (Intel 32bit). I can also play the video on my windows computer using VLC version 1.1.11. The Ubuntu computer that I'm using that does have the fuzzyness from the newly clipped video file is using VLC 1.0.6 Goldeneye. Looks like I'm just going to download the latest VLC so I don't have to deal with the fuzzyness.

Thanks!
