When I try to create a snapshot of a video frame vlc creates an empty .png file. Same with .jpg. vlc output: [00000467] main encoder error: no suitable encoder module for fourcc `jpeg'. VLC probably does not support this image format. or [00000467] main encoder error: no suitable encoder module for fourcc `png '. VLC probably does not support this image format. Reproducible: Always Steps to Reproduce: 1. fire up vlc 2. watch some footage 3. take a snapshot Actual Results: vlc creates a 0 B .png Expected Results: a snapshot from the current video frame

Works fine here. Probably you are missing some use flags. Can you post the output of "emerge -pv vlc ffmpeg"
I have the same problem. Here's the output of the requested emerge command: # emerge -pqv vlc ffmpeg [ebuild R ] media-video/ffmpeg-0.5-r1 USE="3dnow 3dnowext X alsa (-altivec) -amr -bindist -custom-cflags -debug -dirac -doc encode -faac -faad -gsm hardcoded-tables -ieee1394 -ipv6 jpeg2k mmx mmxext mp3 -network -oss -schroedinger sdl -speex ssse3 -test theora threads -v4l -v4l2 -vhook vorbis x264 xvid zlib" [ebuild R ] media-video/vlc-0.9.9a-r1 USE="X a52 aac -aalib alsa (-altivec) -arts -atmo -avahi -bidi cdda -cddax -cddb -cdio dbus -dc1394 -debug dirac -directfb -dts -dvb dvd -esd -fbcon ffmpeg flac -fluidsynth -fontconfig gcrypt%* -ggi -gnome gnutls (-hal) -httpd -id3tag -jack -kate -libass -libcaca (-libgcrypt%*) libnotify -libsysfs -libv4l2 -lirc -live -lua -matroska mmx -modplug mp3 mpeg -musepack ncurses nsplugin ogg opengl -optimisememory -oss -pda png -pulseaudio -pvr qt4 -remoteosd -rtsp -run-as-root -samba -schroedinger sdl -sdl-image -seamonkey -shout -skins -speex sse -stream svg (-svga) -taglib theora truetype -twolame -upnp -v4l -v4l2 -vcdinfo -vcdx -vlm vorbis (-win32codecs) x264 -xinerama xml -xosd xv -zvbi"
Here are my use flags. At the first glance I see nothing that could cause this, but you can try with this configuration if you want. emerge -qpv ffmpeg [ebuild R ] media-video/ffmpeg-0.5-r1 USE="3dnow 3dnowext X alsa (-altivec) amr -bindist -custom-cflags -debug dirac -doc encode faac faad gsm hardcoded-tables ieee1394 ipv6 jpeg2k mmx mmxext mp3 network oss schroedinger sdl speex ssse3 -test theora threads v4l v4l2 vhook vorbis x264 xvid zlib" emerge -qpv vlc [ebuild R ] media-video/vlc-0.9.9a-r1 USE="X a52 aac aalib alsa (-altivec) -arts atmo -avahi bidi cdda cddax cddb cdio dbus dc1394 -debug dirac directfb dts dvb dvd -esd fbcon ffmpeg flac fluidsynth fontconfig gcrypt ggi -gnome gnutls hal -httpd id3tag jack kate libass libcaca libnotify -libsysfs libv4l2 -lirc live -lua matroska mmx modplug mp3 mpeg musepack ncurses nsplugin ogg opengl -optimisememory oss -pda png pulseaudio pvr qt4 remoteosd rtsp -run-as-root -samba schroedinger sdl sdl-image -seamonkey shout skins speex sse stream svg -svga taglib theora truetype twolame -upnp v4l v4l2 vcdinfo vcdx vlm vorbis win32codecs x264 -xinerama xml xosd xv zvbi" There are two configure switches that might affect this issue but "--enable-screen" is tied to the X use flag which we both have enabled and "--enable-snapshot" is disabled in the ebuild. What about making a backup of all config files regarding vlc and trying with an empty configuration. A quick search gave me the following paths in my homedir: $HOME/.local/share/vlc, $HOME/.cache/vlc and $HOME/.config/vlc. From the encoder error it does not look like a configuration issue but who knows. If this does not help I think it is time to assign the bug to the maintainers :)
weird, it works fine here. it uses ffmpeg. Can you try this: ffmpeg -formats | grep png to see if your ffmpeg supports png first. Here I get: DEV D png PNG image
