From a quick look, N and P are still not supported, feel free to
provide a sample.

[FFmpeg-user] Convert EXR image seqs with multiple channels [AOVs] to a Quicktime

2019-07-03 Thread Dan Walker

Hello,

I'm trying to convert a set of EXR image sequences with multiple channels
[AOVs] rendered out of Houdini to a Quicktime.  The flavor of QT doesn't
concern me at the moment.

I'm just looking for a way around this. Below is my current command line
and errors associated with trying to perform the conversion.

Thanks for any help you can provide.

Re: [FFmpeg-user] MLP decoder: decodes 24-bit MLP files into 16-bit MLP wav

Actually, you could think so. But the decoder is fine. On the other
hand, the wav output format defaults to 16 bits.

Just add "-c:a pcm_s24le" as an output option. Then you get the full
sample depth.

Tested and confirmed with sox here as well. ;-)

Hope this helps,

[FFmpeg-user] MLP decoder: decodes 24-bit MLP files into 16-bit MLP wav

2019-07-03 Thread fabrice nicol

The MLP decoder does not seem to work for 24-bit MLP. It converts such 
files into 16-bit WAV, whatever the sample rate.


Example from a (non-encrypted) commercial disc: check the telling chunk:

"  Stream #0:0[0xa1]: Audio: mlp, 96000 Hz, 5.1, s32 (24 bit)
Stream mapping:
  Stream #0:0 -> #0:0 (mlp (native) -> pcm_s16le (native))"

Complete output:

  `ffmpeg -i /mnt/cdrom/AUDIO_TS/ATS_01_3.AOB ~/a.wav`

The output is 16-bit depth as indicated in the console messages. Using 
SoX to corroborate:

My platform is Gentoo Linux amd64.

Is this an undocumented limitation of the MLP decoder or is there 
something I did wrong?
