[FFmpeg-user] Problem transcoding from MP4 (H264 - AAC) to OGG (DIRAC - FLAC)

[Alexis Prus]

Hello,

I am trying to do a lossy-to-lossless transcoding from an MP4 file (with 
one H264 video stream and one AAC audio stream) to an OGG file (with a 
DIRAC video stream and a FLAC audio stream). The command line I am using 
is this:

ffmpeg -i input.mp4 -vcodec libschroedinger -q:v 0 -acodec flac output.ogg

and I am getting the following errors (complete output is at the end):

[ogg @ 0000000001F29570] Unsupported codec id in stream 0
Could not write header for output file #0 (incorrect codec parameters ?)

Does anybody know an appropriate way to do this kind of transcoding?

Thanks in advance,
Alexis
