right click mp4 script

Mr Green · 2007-12-02 10:32:09

Hi,

I am looking for a way to add right click mp4 convertion to nautilus at the moment I use

ffmpeg -y -i '<video_name>' -f mp4 -vcodec h264 -pass 1 -me full -refs 3 -subq 5 -b 700000 -maxrate 768000 -bufsize 244000 -s 320x240 -r 23.976023976 -ac 1 -bf 0 -level 13 -acodec aac -ar 48000 -ab 160000 -ac 2 '<video_name>.mp4'

Only I have to edit video_name each time I run from terminal ;-( would be better in a little bash script

replace video_name with a variable [or use it!]

The above command works ok on flv [although converted video is a little blocky!]

Save the following script to a file (named 'XCodeMP4', for example) in your '~/.gnome2/nautilus-scripts' directory and make the file executable. The script then should appear in your nautilus right-click menu under 'Scripts'.

To transcode files with the script, just right click on a file or group of files, and from the menu, select 'Scripts' > 'XCodeMP4'.

Pay attention to the variables that may need modifying for your situation:

mimes - If you want to add another mime type to the list in this variable, you can obtain the mime from a particular sample file by running:

file -i <filename> |  awk '{print $NF;}'

vidfile_ext - You can change the target file extension here; for example, if you modify your encoding options, this might be desirable.

logfile - The variable is set to save a log file to your Desktop. Change the path if you wish to save the file elsewhere (see sample output below ... it represents the logfile contents). You may also wish to only keep the log for a particular transcoding run, and therefore you need to change the append-to-log code ('>>') to overwrite-log code ('>').

NOTE: I take no responsibility for the ffmpeg options supplied by Mr. Green. Actually, I take no responsibility for any of the code. If you run it, it's yours.

Scipt:

        echo " >>> Transcoding skipped ... '$file' is a directory." \

exit

Mr. Green,

Word of warning here: Codec 'h264' is a raw stream. Use x264 through FFmpeg if you want high quality h264 with reasonable file sizes.

Mr Green · 2007-12-02 19:58:02

ok will give it a go... thanks

You're welcome.

By the way, Skottish is the man when it comes to encoding.

I wish. I've spent hundreds of hours reading websites, forums, tutorials, and documentation, and I'd rank myself as a decent amateur. Some of the people over at http://forum.doom9.org are simply incredible. Those people have true understanding.

I did used to use a script call mp4ize but for some reason the converted file would not work on my ipod...

When I get a minute I will add script to wiki ;-)

I'd double check anything Skottish said regarding the encoding options. Turns out he's just a decent amateur.

Decent Amateur to the rescue!!!

If you have a mp4 file that won't work on Apple stuff, run it through MP4Box from GPAC. If it is in fact a compliant mpeg4 file codec wise, MP4Box will fix it up in a matter of seconds.

Read that vlc will convert stuff but never had much luck doing it ....

Will check out MP4Box

Now if only I could encode my old albums lol
