Re: How to install all video and audio codec

Like it's been said here before, the multimedia is built around gstreamer, but not all plugins are available for whatever the reason. These should be the momentarily available decoders

Code:

[nemo@dhcppc1 ~]$ gst-inspect-0.10 | grep dec

openmax:  omxh263dec: OpenMAX H.263 Video Decoder

openmax:  omxh264dec: OpenMAX H.264 Video Decoder

openmax:  omxmpeg4videodec: OpenMAX MPEG4 Video Decoder

av:  avadec: av audio decoder

speex:  speexdec: Speex audio decoder

rtsp:  rtpdec: RTP Decoder

png:  pngdec: PNG image decoder

mulaw:  mulawdec: Mu Law audio decoder

jpeg:  smokedec: Smoke video decoder

jpeg:  jpegdec: JPEG image decoder

flxdec:  flxdec: FLX video decoder

flac:  flacdec: FLAC audio decoder

annodex:  cmmldec: CMML stream decoder

alaw:  alawdec: A Law audio decoder

vorbis:  vorbisdec: Vorbis audio decoder

theora:  theoradec: Theora video decoder

uridecodebin:  uridecodebin: URI Decoder

uridecodebin:  decodebin2: Decoder Bin

decodebin:  decodebin: Decoder Bin

you can notice for example mpeg2 decoder is missing.(it's part of gst-plugins-ugly which is not installed and not available in the repos)
Also not all plugins from other plugin bundles are available. Yesterday I compiled MPEG-2 transport stream demuxer from -bad, wasn't that hard using the Mer Build engine.

Re: How to install all video and audio codec

I put gst-plugins-ugly on Openrepos now so AC3 should work. Will take a look at VP8/VP9 now.

Edit: Ok, no libvpx in Sailfish so will have to start building that and then look for gst plugins somewhere.

Re: How to install all video and audio codec

libvpx is missing in Sailfish for legal reasons (it's considered risky because of Nokia, but not because it's really infringing), but it can probably be added to Mer (unless Mer project also objects to it).

Re: How to install all video and audio codec

I would love to see this realized... I remember the plugin package we had on the N900 it made it this multimedia beast. any way to recycle old maemo packages.. probably not

not sure what you mean by having to search for gstreamer plugins ? you seem to have that - from freedesktop I assume :)

perhaps this link is useful for libvpx
http://www.linuxfromscratch.org/blfs...ia/libvpx.html

Re: How to install all video and audio codec

Yeah I found vp8 plugin in gst-plugins-bad but I can't get libvpx to build ... yet. Get an error:
"Requested CPU 'cortex-a8' not supported by compiler"

How can you compile a source code? for your exemple.

can you give me all the steps to add vp8 plugin to existing source codec? command lines plz
you are on linux? ubuntu? in terminal...
thanks in advance.

Re: How to install all video and audio codec

n950: Source code can be compiled with Mer SDK, or automatically with the OBS.

Start here:

I've had this in the past with Sony equipment where they have their own codec. The file container format is MP4 but the codec is their own MSNV codec. Not all players support it so you have to convert it to regular MP4 before it'll play.

Handbrake or ffmpeg will probably convert it.
