ffmpeg bug tracker url down?

Hi,

I'm having issues accessing the url bug tracker. Is it down? The replacement
I used for the url is "roundup". I also tried http and https

Thanks,
Josh

I'm afraid it is down. Keep on trying as eventually it will be up.

Joining several files together

Hi,
I want to use ffmpeg.exe to join several files together. for instance taking
a film which has been split into two parts, and joining them into 1 part.
I understand that for certain formats this is possible by simply concating
them together, but I am interested in an general solution which would work
for all formats, and with the ability to transcode etc.

is this possible in ffmpeg.exe today?
if not, would it be possible and how can I help to develop this feature?

Thanks

I'm afraid not.

Yes, by applying this patch:
http://wiki.multimedia.cx/index.php?title=Interesting_Patches#File_concatenation_by_Wolfram_Gloger

> and how can I help to develop this feature?

By re-taking the discussion on this patch and making it acceptable for
inclusion into FFmpeg.

remapping streams

Hi,

I have a problem with the mapping of some input streams to output
streams:

The input file 001.mpg contains:

    Stream #0.0[0x1e0]: Video: mpeg2video, yuv420p, 720x576 [PAR 64:45
DAR 16:9], 15000 kb/s, 25.00 tb(r)
    Stream #0.1[0x1c0]: Audio: mp2, 48000 Hz, stereo, s16, 256 kb/s
    Stream #0.2[0x1c1]: Audio: mp2, 48000 Hz, stereo, s16, 192 kb/s
    Stream #0.3[0x80]: Audio: ac3, 48000 Hz, stereo, s16, 448 kb/s

I would like to get rid of stream #0.2 by mapping.
When I try this ...

ffmpeg -y -i 001.mpg 001-fixed.mpg \
   -map 0:0 -map 0:1 -map 0:3 \
   -vcodec copy -acodec copy -acodec copy -newaudio

I get ...

Input #0, mpeg, from '001.mpg':
  Duration: 01:59:41.28, start: 0.540000, bitrate: 6568 kb/s
    Stream #0.0[0x1e0]: Video: mpeg2video, yuv420p, 720x576 [PAR 64:45
DAR 16:9], 15000 kb/s, 25.00 tb(r)
    Stream #0.1[0x1c0]: Audio: mp2, 48000 Hz, stereo, s16, 256 kb/s
    Stream #0.2[0x1c1]: Audio: mp2, 48000 Hz, stereo, s16, 192 kb/s
    Stream #0.3[0x80]: Audio: ac3, 48000 Hz, stereo, s16, 448 kb/s
Output #0, mpeg, to '001-fixed.mpg':

Problem with configure and literal "$"

I would like to compile ffmpeg binaries and libraries using the 
following linker arguments with --extra-ldflags:-

-Wl,-enable-new-dtags -Wl,-rpath,\$ORIGIN../lib

I finally figured out the correct sequence of escapes to get this to 
work with the binaries produced:-

-Wl,-enable-new-dtags --extra-ldflags=-Wl,-rpath,\\\\\$\\\$ORIGIN/../lib

However, the libraries do not get the correct arguments. They have a 
RUNPATH of "RIGIN/../lib" as opposed to the binaries which have the 
correct "$ORIGIN/../lib". I have had a look through the configure 
script, but I cannot work out where the problem is occurring.

libx264 and ffmpeg

Hello:

I am using an SVN build from 11th October (Packman package) of ffmpeg to try
to encode a VOB video to MP4 via libx264 and am having some issues setting
and limiting the bitrate.

I have tried using commands -b 1200, -b 1200k and -b 1200kb as well as -bt
100 (with and without k, kb) and have tried adding -rc_eq
"blurCplx^(1-qComp)" as well but the bitrate of the encoded video always
ends up around the 2500 kb mark which I am assuming is a default of some
kind.

Does anyone have any advice on how to limit the bitrate to 1200kb and even
better, how to encode at a constant bitrate?

Cheers,

David
