-
- @section ffserver doesn't not work.
-
- ffmpeg development is now concentrated on the codec and format
- handling. New developments broke ffserver, so don't expect it to work
- correctly. It is planned to fix it ASAP.
-
- @section I cannot read this file although this format seems to be suppored by ffmpeg.
-
- Even if ffmpeg can read the file format, it may not support all its
- codecs. Please consult the supported codec list in the ffmpeg
- documentation.
-
- @section I get audio/video synchro problems when grabbing.
-
- Currently, the grabbing stuff does not handle synchronisation
- correctly. You are free to correct it. It is planned to fix it ASAP.
-
- @section How do I encode jpegs to another format ?
-
- If the jpegs are named img1.jpg, img2.jpg, img3.jpg,..., use:
-
- @example
- ffmpeg -i img%d.jpg /tmp/a.mpg
- @end example
-
- @samp{%d} is replaced by the image number.
-
- @file{img%03d.jpg} generates @file{img001.jpg}, @file{img002.jpg}, etc...
-
- The same system is used for the other image formats.
-
- @section FFmpeg does not support codec XXX. Can you include a Windows DLL loader to support it ?
-
- No. FFmpeg only supports open source codecs. Windows DLLs are not
- portable, bloated and often slow.
-
- @section How can I read from the standard input or write to the standard output ?
-
- Use @file{-} as filename.
-
- @chapter Development
-
- @section Can you support my C compiler XXX ?
-
- No. Only GCC is supported. GCC is ported on most systems available and I
- don't see the need to pollute the source code with @code{#ifdef}s
- related to the compiler.
-
- @section I want to use ffmpeg or libavcodec under Windows. Can you support my proprietary C compiler XXX ?
-
- No. Use @code{mingw-gcc} available at @url{http://www.mingw.org/} to
- compile the code. It generates object files fully compatible with other
- windows compilers.
-
- @section Can you add automake, libtool or autoconf support ?
-
- No. These tools are too blowted and they complicate the build. Moreover,
- since only @samp{gcc} is supported they would add little advantages in
- terms of portability.
-
- @bye
