how can i merge two files with ffmpeg?
one is : /home/pt/t/pa1.flv
the other is : /home/pt/t/pa2.flv
1 o merge with ffmpeg
ffmpeg -i /home/pt/t/pa1.flv -i /home/pt/t/pa2.flv -vcodec copy -acodec copy /home/pt/t/dd.flv
the problem is: the merged file ( /home/pt/t/dd.flv ) just contain one file--the first one
/home/pt/t/pa1.flv,there is no the second file--/home/pt/t/pa2.flv in the /home/pt/t/dd.flv

I am using ffmpeg for merge wav files to a mov video. My doing is below
1. First extract audio (wav file) from video
2. Create wav file from mp3 track 1
3. Create wav file from mp3 track 2
4 Merge extract audio from video with track 1 and track2.
Now finally create a new video with original video's video stream and merged audio stream.
Process is working. However final video is 3-4 times greater than original one. I want that final video should be near about size of original video. As I understand, all three wav files (created from ) make video larger.
Example commands i using is as below:
I'm running ClipBucket on my Ubuntu 10.04 LTS server x64.Conversion of AVI to FLV works just fine, however when I try to upload an MPG file, it fails. Apparently I should recompile ffmpeg to allow for MPG > FLV conversions.

I have a bunch of RTF files that I need to merge into just one RTF.
I'm sure there is an easy way to do this, but I just can't find out how
I have a movie split into 3 iso image files, say, movie-1.iso,movie-2.iso, and movie-3.iso I did the following:
[ewn]# cd /mnt
[mnt]# mkdir disk1 disk2 disk3
[mnt]# mount -t iso9660 -o ro,loop=/dev/loop0 /media/Hitachi_SATA_2TB/iso_files/Movies/movie-1.iso /mnt/disk1
[mnt]# mount -t iso9660 -o ro,loop=/dev/loop1 /media/Hitachi_SATA_2TB/iso_files/Movies/movie-2.iso /mnt/disk2
[Code]....
the files for disk2, disk3 are exactly the same except disk2 has 2 .vob files instead of 3. Can I make this work by changing the names of some of these files before merging them into one directory and then running the mkisofs command to create a new single iso image? If so, what names do I give so that the movie plays correctly? If not, just how do you do this?
Searching Google on how to join/merge many mp3 files, it suggests that I should just cat them together.That might "work", but clearly it is not the correct way to do it, as each header and set of IDv3 tags will also be concatenated.Does a Linux program exist that can be scripted to join/merge many mp3?Can mplayer/mencoder/ffmpeg do it?

1. Is there an easy way to combine pdf files not only one "after" the other, but also one "next to" the other? For example, If I have one-page files called a1.pdf, a2.pdf, a3.pdf, a4.pdf, b1.pdf, b2.pdf, b3.pdf, b4.pdf, c1.pdf, c2.pdf, c3.pdf, c4.pdf, I want to combined them so that I can scroll down from a to c and scroll right from 1 to 4. That is, I want to merge them in "matrix form". If I zoom out the final file should look like:
a1 a2 a3 a4
b1 b2 b3 b4
c1 c2 c3 c4
(TWELVE pages in total)
Is this possible? I tried Google but found no information.
2. Also, is it possible to just put all of them together in a single page. If I zoom out the page should look like:
a1a2a3a4
b1b2b3b4
c1c2c3c4
(ONE page in total)
Note: I would like to do this for many one-page files

I have a folder with hundreds of .txt files (logs of some java application) that I have to merge in to one single .txt file. This application produces a new log file everyday:

...
day8: logFriday17September2010.txt

and so on...
I could merge the files easily with "cat" and ">>" however, the problem is that I have to do it by taking into account the date (creation or modification) of the file.
If I simple use the cat command the output file will receive for example, all Fridays in a row, then all Saturdays, etc. and in that way I'm not considering the date.
I've searched for the options of the find command, since the files after creation are not modified...I try to use this for example:
$ find . -newer <some old file>
but that lists me all files after that <old file> and not by correct date.

View 2 Replies View RelatedI've got a bunch of HD files in .mkv format that I want to convert to a format that the 360 will read (currently just trying .avi files) so I can stream the media to my xbox360. I'd rather avoid transcoding the entire file, so I tried unpacking the .mkv file into audio and video (and subtitle if necessary) and repacking said file into avi using ffmpeg. The repacking is where I am having the problem. Here's the commands I tried at first (it might look familiar):
Code:
mkvextract tracks file.mkv 1:temp_video.avi 2:temp_audio.ogg 3:temp_sub.srt
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy file.avi
However, I keep getting this annoying error:
Code:
Error while opening codec for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height Where stream #0.1 is the output audio stream to the .avi file. I think I have narrowed it down to the fact that the input streams are all 6 channel (5.1 surround sound) which mp2 doesn't support (the ffmpeg audio default) so I did this instead:
Code:
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy -acodec libmp3lame file.avi
I'm still getting the same error, but when I use
Code:
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy -acodec libmp3lame -ac 2 file.avi
to change the sound to stereo it works. Problem is I'd like to keep my media in surround sound. Any thoughts on how to get all 6 channels in the new mp3 file? I'm fairly certain that mp3s support 5.1. And after some messing around, I haven't found that my ffmpeg can transcode audio format from 5.1 back to 5.1. So since (I think) the 360 can play .ac3 files I decided to just copy both the video and audio file to the .avi file sans transcoding using
Code:
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy -acodec copy file.avi
however now about halfway through, I run into this error:
Code:
NULL @ 0x22f3a00]error, non monotone timestamps 62562 >= 62562
av_interleaved_write_frame(): Error while opening file I can't seem to find any solution to this problem anywhere online, does anyone know how to get around this? I'd prefer to use ffmpeg for this if possible. (so I can write a script and just attack an entire directory at once) For what it's worth, I'm using the latest ffmpeg in the ubuntu (karmic) default repositories.
