-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all: I'm testing thusnelda and I'm trying to use the two-pass feature, but when I try it with /usr/bin/ffmpeg2thusnelda /home/raster/Escritorio/devede/holidays\ at\ galicia.mpg -o /home/raster/output.ogv -v 10 -a 10 --optimize - --first-pass /home/raster/output.ogv.firstpass_data I receive the error Could not set up the first pass of two-pass mode. Did you remember to specify an estimated bitrate? Does that mean that, when using two-passes, I must set a video bitrate, and cannot rely only in the -v and -a parameters? I've been searching in google but can't find info about this.

Encoding the sound in the firstpass is useless from what I experienced with encoder_example. I use the following: ./encoder_example --soft-target -v 7 -V 3397 --two-pass --first-pass "$VIDEO".pass stream.yuv -o "$VIDEO".ogv ./encoder_example --soft-target -v 7 -V 3397 --two-pass --second-pass "$VIDEO".pass -a -1 stream.wav stream.yuv -o "$VIDEO".ogv Regards -- ZikZak -------------- next part -------------- An HTML attachment was scrubbed...
