I'm using a boatload of different versions of lame to do live
encodings for streaming, in a pipeline receiving raw PCM data
and then spewing the encoded mpeg data out for icecast streaming,
using FreeBSD.
I just discovered that the latest CVS version isn't doing this
for me (no suitable output sent to stdout), while the beta 3.83
package (19.May) is fine.
Further testing reveals that CVS of 22.May 12.00 GMT+2 is fine,
while 23.May 00.00 GMT+2 is b0rken. There are a couple diffs in
place, but the file which seems to `fix' things if restored from
the `good' source is quantize-pvt.c
If I take the below patch, which is the diff of quantize-pvt.c
over these 12 hours on 22.May, and I apply it to the latest
CVS source, then lame works fine in a pipeline again. (Well,
it seems to require twice the CPU of 3.83, which is more than
the machine doing three live streams can deliver, but it does
deliver encoded output that I can listen to.)
I haven't dug around to see how this patch below might make a
difference with stdin/stdout and why, but without it, what I
get is nothing for several minutes, then repeated MPEG headers
(with the lame version) sent to stdout, with the identical
command pipeline that works as expected with 3.83.
(here the diffs applied on 22.May from CVS)
