요런 에러가 발생한다.

물론, 컴파일도 제대로 완료되지 못하고 결과물도 생성되지 않는다.
버그리폿하려다가 그냥 STLinux2.3에 들어있는 sh4-linux-gcc로 하니 문제없이 해결!

아무튼, PATH 변수의 경로를 바꾸는 법이 있다지만, 귀차니즘으로 인해
config.mak 파일의 CC= AS= 등에
전부 절대경로로 바꾸어 넣어주었다.

The server is too busy to serve your request at this time.

The bandwidth being served (including your stream) is 3758kbit/sec, and this exceeds the limit of 1000kbit/sec.

ffserver.conf의 설정은 video가 1872kb / audio 가 1886kb 였고
합쳐서 3758kb 인데 이는 1000kbit의 데이터 폭을 넘어선다는 에러인 듯 하다.


아무튼 http://localhost:8090/test.asf로 접속하면


위와 같은 화면이 뜬다.

머.. ffmpeg 홈페이지의 ffserver 문서와 다를 내용은 그리 없지만

As a simple test, just run the following two command lines where INPUTFILE is some file which you can decode with ffmpeg:

./ffserver -f doc/ffserver.conf &
./ffmpeg -i INPUTFILE http://localhost:8090/feed1.ffm

At this point you should be able to go to your Windows machine and fire up Windows Media Player (WMP). Go to Open URL and enter

아무튼.. wmv 중요한건 저게 아니라 /etc/ffserver.conf 파일의 내용일 듯 하다.

# ffserver can also do time shifting. It means that it can stream any

# File=/tmp/feed_name.ffm FileMaxSize=5M
File /tmp/feed1.ffm

# You could specify
# ReadOnlyFile /saved/specialvideo.ffm
# This marks the file as readonly and it will not be deleted or updated.

Gnash is a GNU Flash movie player. Flash is an animation file format pioneered by Macromedia which continues to be supported by their successor company, Adobe. Flash has been extended to include audio and video content, and programs written in ActionScript, an ECMAScript-compatible language. Gnash is based on GameSWF, and supports most SWF v7 features and some SWF v8 and v9.

March 10, 2009

It has been a very long time since we last made a release and many did not think we would make one again but, back by popular demand, we are proud to announce a new release: FFmpeg 0.5. Check out the release notes and changelog.

It is codenamed "half-way to world domination A.K.A. the belligerent blue bike shed" to give an idea where we stand in the grand scheme of things and to commemorate the many fruitful discussions we had during its development.

This release includes a very extensive number of changes, but some of the highlights are:

  • Significant work to support at least decoding of all widespread mainstream proprietary codecs, such as:
    • decoders and encoders
      • ALAC
      • Flash Screen Video
      • WMAv2 decoder fixed, WMAv1/v2 encoder
    • decoders
      • Atrac3
      • MLP/TrueHD
      • On2 VP3 improvements and VP5/VP6 support
      • RealAudio Cooker and fixes for 14.4 and 28.8
      • RealVideo RV30/40
      • WMV3/WMV9/VC-1 and IntraX8 frame support for WMV2/VC-1

 비디오 종류
    * FLV1:Sorenson H.263
    * FLV4:On2 TrueMotion VP6
