amarok-148.pngI’ve just rebuild Amarok 1.4.8 for Mandriva 2008.0 with MySQL and PostgreSQL support.

This was also an opportunity for me to rebuild old packages (Interreta Televidilo, Rugg and python-icalendar) for Mandriva 2008.0. For now there is no x86_64 version of the packages (including Amarok). I plan to do it later.

Update: Amarok was recompiled to include latest libgpod version (0.6.0).

Amarok 1.4.7 for Mandriva 2007.1I’ve just backported Amarok 1.4.7 from cooker to Mandriva 2007.1 (aka “Spring” edition).

Packages are downloadable from my RPM repository for i586 and x86_64 architecture and both build support SQLite, MySQL and Postgresql as database backend.

I’m happy to announce you that the latest version of Amarok for Mandriva 2007 now feature a fully functionnal MusicBrainz ! Look at the screenshot for evidences.

This build, named amarok-1.4.4-3, is exactly the same as previous one (i.e. with SQLite, MySQL and Postgresql support). Don’t forget to update the libtunepimp package from my repository and use the 5.0 version.

  • Change the aspect ratio of a film for the playback. Standard aspect ratio are : 1.33 (4:3), 1.66 (1.66:1), 1.77 (16:9) and 2.35 (2.35:1):

    mplayer -aspect 2:1 ./video.avi

  • Play the video with subtitles:

    mplayer -sub ./subtitle_file.txt ./video.avi

  • This will extract audio track no. 128, downmix the AC3 sound to PCM and write the results to file.wav:

    mplayer -vo null -hardframedrop -aid 128 -ao pcm -aofile file.wav dvd://1

  • This will extract the audio, convert it to PCM and write the resulting wave file to audio.wav:

    mplayer -vo null -hardframedrop -ao pcm:file=audio.wav myvideo.avi

  • Extract to chapter.txt the chapter file of the track n°1 of the DVD:

    dvdxchap -t 1 /mnt/cdrom > chapter.txt

  • Show all subtitles streams:

    mplayer -vo null -ao null -frames 0 -v 2 dvd://1 >&1 | grep sid

  • Extract the raw subtitle stream. The -a 0x21 option correspond to the subtitle stream’s hexadecimal number (= 0×20 + id of the stream):

    tccat -i /space/st-tng/dic1/ -T 1 -L | tcextract -x ps1 -t vob -a 0x22 > subs-en

  • Create a rotated copy of the file.avi video (rotate=1 : clockwise ; rotate=2 : anti-clockwise):

    mencoder -vop rotate=2 -oac pcm -ovc lavc ./source.avi -o ./dest.avi

  • Preview a video composed of all jpeg files from the current folder at 15fps (mplayer only support jpeg, png, tga and sgi formats):

    mplayer "mf://*.jpg" -mf fps=15

  • Create a 15fps video from all jpeg files of the current folder:

    mencoder "mf://*.jpg" -mf fps=15 -ovc lavc -o ./dest.avi

  • Encode a SVCD to AVI file:

    mencoder -oac lavc -ovc lavc vcd://1 -o ./svcd.avi

  • Transcode video to raw format (be carefull: usually the output video got annoying audio delay):

    mencoder -oac pcm -ovc raw -ofps 25 -noskip ./video.wmv -o ./video.avi

  • Encode a video using the default mpeg4 codec at 400 kbps for video and mp3 codec at constant 32 kbps bitrate for audio:

    mencoder -oac mp3lame -lameopts cbr:preset=32 -ovc lavc -lavcopts vbitrate=400 in.avi -o out.avi

  • Enhance the sharpness of the video:

    mplayer video.avi -vf smartblur=.6:-.5:0,unsharp=l5x5:.8:c5x5:.4

  • Merge multiple video into one:

    avimerge -i part1.avi part2.avi -o big-file.avi

  • Cut a video to keep the first 5.4 seconds:

    mencoder big-file.avi -ss 0 -endpos 5.4 -ovc copy -oac copy -o cutted.avi

  • Cut a video to keep everything exept the first 5.4 seconds:

    mencoder big-file.avi -ss 5.4 -ovc copy -oac copy -o cutted.avi

  • Show all mplayer filter list:

    mplayer -vf help

  • Get help of a particular filter (eq2 in this example):

    mplayer -vf eq2=help

  • Here is the filter I use to light up a video taken in the dark with my cheap camera. Of course it add noise but thanks to this we can distinguish shapes in the dark.

    mencoder -vf eq2=1.61:1.95:0.54:2.43 -oac pcm -ovc lavc video.avi -o bright-vid.avi

  • And this is the command to preview the result of the filter used above:

    mplayer video.avi -vf eq2=1.61:1.95:0.54:2.43

  • This is how I convert raw videos taken with my digital camera into ISO standard MPEG-4 (DivX 5, XVID compatible) videos [to encode in grayscale, add :gray option to -lavcopts]:

    mencoder source.avi \
    -ovc lavc -oac lavc -ffourcc DX50 \
    -lavcopts vcodec=mpeg4:vbitrate=400:v4mv:mbd=2:trell:autoaspect:dia=2:acodec=mp3:abitrate=32:vpass=1 \
    -vf hqdn3d -o output.avi
    mencoder source.avi \
    -ovc lavc -oac lavc -ffourcc DX50 \
    -lavcopts vcodec=mpeg4:vbitrate=400:v4mv:mbd=2:trell:autoaspect:dia=2:acodec=mp3:abitrate=32:vpass=2 \
    -vf hqdn3d -o output.avi

  • Play all videos of the current folder fullscreen at 4x speed with 50% more brightness:

    mplayer -speed 4 -brightness 50 -fs ./*.avi

  • Extract audio stream from a video:

    mplayer -dumpaudio -dumpfile audio.ac3 video_source.mpg

  • Test XV video driver output via gstreamer v0.10:

    gst-launch-0.10 videotestsrc ! xvimagesink
