From
-t duration (input/output)
When used as an input option (before -i), limit the duration of data read from the input file.
When used as an output option (before an output url), stop writing the output after its duration reaches duration.
So this should yield a 1-minute file with timestamps starting at 1:49, right?

Wrong. It outputs a file with no frames:
-rwxrwx--- 1 root users 805 Jul 30 01:36 timing-1m49s.mkv
I have to specify -t 1:49 or more, and e.g. -t 1:55 produces a 6-second file that starts at 0:00 and according to the metadata should last 1:55.
I arrived at this point trying to extract a clip and add subtitles in the same command, but this minimal case looks to me contrary to the documentation.
Yes, the -t used as output option looks at the timestamps, which usually start at zero. Except for cases like these when -copyts is used. Use -t as input option:
ffmpeg -y -copyts -ss 1:49 -t 1:00 -i ~/Videos/input.mkv -c copy timing-1m49s.mkv

I'm trying to capture a screenshot from a udp stream using ffmpeg in a Ubuntu 14.04 System.
Following is the command
ffmpeg -y -i udp_ip -vframes 1 -q:v 1 test.png
But the image captured is of very poor resolution and I observed a lag while taking the screenshot.
Please suggest a best tool or a way to take a screenshot in the fastest way and also of the best image resolution possible.

Since, this seems to be an issue of aspect ratio, and not quality, per se, use
ffmpeg -y -i udp_ip -vf scale=iw*sar:ih,setsar=1 -vframes 1 -q:v 1 test.png
The scale filter rescales the video to square pixels. The SAR filter isn't strictly necessary but in case the PNG muxer writes that data, better to reset it.
I am trying to run a merge between a mp4 video and a m4a audio files. Several other were generated properly, but this one starts and freezes at time 00:02:54.08. If I stop it (ctrl+c) several minutes afterwards, the output.mp4 file have 0 bytes. I do not have a lot of clues why it happens. Anybody experienced something similar?

If this stops after few seconds, there's some anomaly in one of the bitstreams and you'll have to remux one or both of the input files and try again i.e.
ffmpeg -i video -c copy -an newvideo.mp4
ffmpeg -i audio -c copy -vn newaudio.mp4
I have a .ts file (Download files here: http://dropcanvas.com/2gmsg/1).
I want to split this video while I expect ALL other properties remain same including pts time.
Here is what I try to achieve this:
ffmpeg -ss 0.000 -i sample.ts -y -c copy -t 3 splitted.ts
Expected start time: 94678.950389
New start time: 1.402367
I expect the above command should only take first 3 seconds of the .ts file and all other stuff to stay same. I've seen copyts and copytb options from the documentation but I wasn't able to use them.
So how do I do this?
Thank you
Here are the logs for copyts. It creates a 0 byte splitted.ts file:
ffmpeg -ss 0:00:00 -i sample.ts -to 00:00:03 -y -c copy -copyts splitted.ts

ffmpeg -seek_timestamp 1 -ss 94678.950389 -i sample.ts -y -c copy -copyts -to 94681.950389 -muxdelay 0 splitted.ts
Your original command can work if you use the frames flag.
ffmpeg -ss 0.000 -i sample.ts -y -c copy -copyts -muxdelay 0 -vframes 90 splitted.ts
Where 90 represents amount of frames in t seconds.
I want to trim a video with the following command:
ffmpeg.exe -i in.mp4 -ss 76 -t 10 -c copy -an out.mp4
which exactly means, copy 10 seconds after 76 seconds, and don't copy audio. However out.mp4 is 5 seconds length.
This is ffmpeg console output:
ffmpeg.exe -i in.mp4 -ss 76 -t 10 -c copy -an out.mp4

When I analyze this console output I see this inconsistency. It says output time is 9.96 seconds. On the other hand it says frame is 143, so from the latter information I can calculate duration by frame/fps which is 143/23.98=5.96.
Another strange behaviour with this copy command is when I change the start time to something else output video length is varying between 5-10 seconds depending on the start time.
What might be the problem causing these unexpected behaviours?
ffmpeg only cuts at keyframes, so with inter-coded streams, you may not get exact duration. You'll have to transcode the video for a precise cut.
ffmpeg.exe -ss 76 -t 10 -i in.mp4 -an out.mp4
(Placing the -ss and -t before the input will make ffmpeg seek to the position and then decode frames. Placing them afterwards means ffmpeg decodes all frames and then discards till start time is reached)

I tried:
ffmpeg -f concat -i files.lst -c copy output.mp4
But the output file doesn't have the subtitles stream. How do I fix this?

ffmpeg -f concat -i files.lst -c copy -scodec copy output.mp4
