WAVE / PCM missing

[Marsjanin]

Hello.

After system upgrade I cananot find pure WAVE / PCM 16 bit on sound output. I just can have Intel ADPCM compressed to 4 bits.

I need WAV with custom sampling rate (same as input, that is 11024 (NOT 11025!)), because I prefer "encode" to as uncompressed as possible (mjpeg for video) in OpenShot, then compress it by my own scripts in FFMPEG.

FFMPEG of course has "pcm_s16le", the question do, is OpenShot use FFMPEG for encoding?

Thanks for any solution.

We use FFmpeg via MLT - pcm_s16le is listed on my system.

Well. I started to search forum a bit more and I found this:
viewtopic.php?f=27&t=1150&p=5360&hilit=codec#p5360
You said there:

I've never seen flac appear under video formats on my system

Well, also I can see flac and many more strange formats in the container ("video format") field, including my s16le
I think something is messed up… These all happened after upgrading system to Gnome 3 (Gnome 3 was included in a huge update pack).

My OS is Linux Mint Debian Edition (LMDE) 64 bit.

Are there important things, I can check installed versions, etc.? What is that MLT, I searched some in Synaptic, I got some libmlt* libraries, but I don't know, which ones are important here.

It's the way MLT/FFMpeg output the container formats - they don't separate them out to audio/video specific formats, unlike the codecs which they do split out.

So this is not the clue…
What can I else install, that OpenShot can "see" as available codecs?
And maybe should OpenShot force itself to require all compatible codecs, using dependencies (Debian compatible), so there's nothing to install more? I got no idea now. I can choose between:

none, aac, ac3, ac3_fixed, adpcm_adx, adpcm_ima_qt, adpcm_ima_wav, adpcm_ms, adpcm_swf, adpcm_yamaha, alac, dca, eac3, flac, g722, g723_1, g726, libaacplus, libfaac, libgsm, libgsm_ms, libmp3lame, libopencore_amrnb, libspeex, libvo_aacenc, libvo_amrwbenc, libvorbis, mp2, nellymoser, real_144, roq_dcpm, sonic, sonicls, vorbis, wmav1, wmav2.

I'm really confused. Only lossless I know seems to be FLAC (maybe libFAAC too?). I'm not sure if FLAC can support all samplings that WAVE can.

[Andy]

Well I have 'wav' appear under Formats and pcm_s16le appear under audio codecs. I haven't done anything special to get those, as far as I am aware they are supported by libavformat/libavcodec out of the box.

I don't know what to suggest to enable support for those on your system.

[Marsjanin]

OK then, I'll try to solve this later…
Thanks for input.

Just saw this, which might be related to your problem:

[Marsjanin]

Thanks for that link, looks like this is it.
I tried to fix that by compiling fixed (newest) MLT, but I can't get it, there are some dependency errors. Nevermind, I think I have to wait when the fix will be added to my repo (now I even don't know, what is the right packet: libmlt++3, libmlt-data, libmlt4 or python-mlt3…
