I want to convert an elementary stream(.264) to container format(.mp4).
Can someone please help me on this? How can I use ffmpeg to do this task? What are all the other methods that could accomplish the same task?

You will need to install these :
sudo apt-get install ffmpeg libavcodec-unstripped-52 libavdevice-unstripped-52 libavformat-unstripped-52 libavutil-unstripped-50 libpostproc-unstripped-51 libswsclale-unstripped-0 x264
In Karmic, Lucid and Maverick you should replace "unstripped" by "extra" but since there is transitional packages this work too.
And then you can use a script with :
for i in *.avi; do ffmpeg -i "$i" -f mp4 "`basename "$i" .avi`.mp4";done
And you can use options like these to set up resolution, video codec and audio codec and audio quality :
for i in *.avi; do ffmpeg -i "$i" -s 352x288 -vcodec libx264 -vpre default -acodec libmp3lame -ab 192k -ac 2 -ar 44100 -f mp4 "`basename "$i" .avi`.mp4";done
Arista Transcoder 
or from command line
sudo apt-get install arista -y
You can use this software, that I always use and I think it's really good. To convert an ogv file to mp4 you should choose any Sony device.

This is easy with
ffmpeg:This simply stream copies (re-muxes) the video so there is no unnecessary re-encoding occurring; therefore the quality is preserved and the whole process is quick.
Frame rate is by default assumed to be 25. You can change this with the
-framerateinput option. Typical values are30000/1001,25(default),24000/1001,24, or frame rate aliases such asntsc,ntsc-film, orpal.If you don't know the frame rate, you can perform the conversion using your best guess as to the frame rate, and then compare the running duration of the output file with the input file running duration and then calculate the actual frame rate. e.g. assume 24 fps and actual running time of 1:00:00 (60 mins) if resulting file has running time of 1:02:30 (62.5 mins) then actual frame rate is 25 fps (24 * 62.5 / 60)
