Re: Channel_Layout and AMerge

Use:

Code: Select all

amerge=inputs=2,aformat=channel_layouts=stereo
for each output.
If this still does not work, post FULL UNCUT ffmpeg command AND output.

If you ever had read documentation of hstack filter, you would notice that it needs number of inputs, by default that number is 2.

In documentation it is clearly stated that weights are separated with space, and not with '|'.

Re: Missing SOFAlizer filter

I added single multichannel mode to headphone filter, so for example for 7.1 setup you will need to create 16 channels wav file. Wav files can be found on internet, and you can pick wavs and merge them with amerge filter. Just note that both order of mapping for headphone filter and also for merging...
