So how did you compile it? Looking at http://slackbuilds.org/repository/14...imedia/ffmpeg/ I see lots of compile-time options for codecs that you can enable or disable. And this is one of the lines:

Code:

LAME=yes|no (default: no), requires lame

Looks like by default, MP3 encoding support is disabled.

You can export variables like:

Code:

# export FFMPEG_LAME=yes FFMPEG_SPEEX=yes FFMPEG_X264=yes

and then:

Code:

# slpkg -s sbo ffmpeg

allenlinux · 08-16-2015, 01:14 PM

its posible any way to include all variables ?, or i have to set line by line. ?

allenlinux · 08-16-2015, 01:23 PM

dslackw thanks to all

i solve with the export lines.

notKlaatu · 08-16-2015, 01:24 PM

You can go into the SlackBuild script and set the variable to yes. Then execute the script as usual.

Personally, I'll use sbopkg to edit the slackbuilds and remove any checks on options I want. For me, it is much easier than copying and pasting a ton of different variables to the commandline. This also allows me to still use the ncurses version easily.

I switched mine from:

Code:

# Unfortunately ffmpeg's configure doesn't support --enable-feature=yes
# syntax, so we have to do it the complicated way :/

i feel it about it. i mean, i set the yes var to "yes" on ffmpeg slackbuild, but on the right side still the "no"option, its like confusing yes and no at the same time. Mr bassmadrigal, your setting include all variables?. it seems it does. Thanks.

Not all, but all that I had installed. Basically, you want to remove everything before and including the && symbol.

So

Code:

mp3lame=""    ; [ "${LAME:-no}" != "no" ]         && mp3lame="--enable-libmp3lame"

would become

Code:

mp3lame="--enable-libmp3lame"

For any variables you don't want to use, you can either keep them as is, or just remove them from the Slackbuild.

Other slackbuilds might include an if/then statement. I'll remove the if statement on any that I want to use. This example is the kodi slackbuild, and I want to enable the webserver, but not the other options.

Code:

# The version of ffmpeg on SBo is too old to compile kodi.
# Optional ffmpeg is still available but not turned on by
# default.
if [ "${FFMPEG:-no}" == "yes" ]; then
  OPT_DEPS="--with-ffmpeg=shared"
else
  OPT_DEPS=""
fi

# Build webserver. Requires libmicrohttpd.
if [ "${WEBSERVER:-no}" == "yes" ]; then
  OPT_DEPS="$OPT_DEPS --enable-webserver"
else
  OPT_DEPS="$OPT_DEPS --disable-webserver"
fi

# Use pulseaudio.
if [ "${PULSE:-no}" == "yes" ]; then
  OPT_DEPS="$OPT_DEPS --enable-pulse"
fi

Edited, it would be:

Code:

# The version of ffmpeg on SBo is too old to compile kodi.
# Optional ffmpeg is still available but not turned on by
# default.
if [ "${FFMPEG:-no}" == "yes" ]; then
  OPT_DEPS="--with-ffmpeg=shared"
else
  OPT_DEPS=""
fi

# Build webserver. Requires libmicrohttpd.
  OPT_DEPS="$OPT_DEPS --enable-webserver"

# Use pulseaudio.
if [ "${PULSE:-no}" == "yes" ]; then
  OPT_DEPS="$OPT_DEPS --enable-pulse"
fi

You'd just have to look through and see how they manage their optional variables and edit accordingly.
