Re: Rate control with libx264 not working for me. Rats!

I tried using -b/-bt in conjunction with Robert Swain's preset files
and they are working.
Yay!  So. . . which options need to be set to convince ffmpeg/libx264
to pay attention
to -b and -bt?  I don't see this documented anywhere.  Thanks!

Re: ffmpeg SoC - Frame-based multithreading by Alexander Strange

Hi,

AFAIK, only the generic part of frame based multithreading is
implemented yet, and the codecs have to be ported separately.

I suppose they are working very hard on it right now.
(Don't know which development tree/repository/copy they use internally)

This is a very interesting feature and I'm really looking forward to
being able to compile the first fully-multithreaded MPlayer.

Live http output/targets

I'm interested in sending the output from ffmpeg to generic web server, 
and having code on that server receive the stream (either piping it a 
file or relay to users via circ. buffer etc).

Just running a couple quick tests I see ffmpeg sends a POST with 'Range 
= bytes=0-', which implies it is a open-ended stream, like one would 
expect...

However even though my log show a 200 response was sent, something is 
aborting the stream; ffmpeg (a svn build from May this year) exits with:

av_interleaved_write_frame(): Error while parsing header

when I run something like:
ffmpeg -i test.wav -f mp3 -ac 2 -vn http://localhost/snoop.jsp

, even if I set up a URI on the server that accepts a open-ended 
input-stream and not expecting http-param or newline formatting. Ive 
tried various other output-stream formats including mpeg and mpegts.

Is there a doc that describes the protocol ffmpeg wants to use over a 
generic http server? Might there be a two-way setup/protocol on the 
socket before ffmpeg starts sending the data?

Thanks!!

Problem compiling in windows: unimplemented lrintf?

Decode Panasonic HDC-SD100 AVDHCD (H.264) videos to PAL DVD, output video plays too slow


Hi, 

I have problems with converting videos from my new full HD camcorder
(Panasonic HDC-SD100) to other formats like PAL-DVD. The PAL-DVD
encoded video plays too slow. I read manuals FAQs, tried different
options but no help with pure ffmpeg command.

ffmpeg is very new from svn and x264 also new from git (both less than
one week old) (x264 from here: http://git.videolan.org/)

My basic command and output:

Great =)

Well, to start off, why are you using r14160?

And as for the MinGW version, I personally don't recommend using the 
bundles. They rarely work out of the box for FFmpeg. I suggest you 
always install the latest packages manually. Actually I don't know what 
comes in 5.1.4, but it probably isn't enough.

You can follow the wiki at http://ffmpeg.arrozcru.com/wiki , but it is 
long and boring and more suited for people that have no idea what 
they're doing. Since you don't fall in that category, I'll try to sum it 
up more concisely:

MSYS:
- Install the old 2004 package for MSYS (don't post-install anything);
- Update msys dll to the latest version;
- Update make to msys-make-3.81-2;
- Update bash to 3.1;
- Install pr from the coreutils package.

MinGW:
- Install latest binutils;
