[FFmpeg-devel] [PATCH] avformat/cache: rename the class name fro Cache to cache

[Steven Liu]

Because the protocol name is cache, but the class name is Cache.

for example:
ffmpeg -protocols will show:
Supported file protocols:
Input:
  async
  bluray
  cache
  concat
  crypto
  data
  ffrtmphttp
  file
  ftp
  gopher
  hls
  http
  httpproxy
  https
  mmsh
  mmst
  pipe
  rtmp
  rtmps
  rtmpt
  rtmpts
  rtp
  srtp
  subfile
  tcp
  tls
  udp
  udplite
  unix
Output:
  crypto
  ffrtmphttp
  file
  ftp
  gopher
  http
  httpproxy
  https
  icecast
  md5
  pipe
  prompeg
  rtmp
  rtmps
  rtmpt
  rtmpts
  rtp
  srtp
  tee
  tcp
  tls
  udp
  udplite
  unix

But i cannot find the cache protocol in help message
