[FFmpeg-trac] Cannot transcode streaming to mp4

[Asoul]

Hi,

I want to use ffmpeg for transcoding RTP streaming to MP4(HTTP) streaming, so I can play in html video tag,

but I can only transcode to flv format successfully.

Below is my settings:

[/etc/ffserver.conf]

...

<Feed feed1.ffm>
  File /tmp/feed1.ffm
  FileMaxSize 5M
  ACL allow localhost
</Feed>

<Stream flv>
  Feed feed1.ffm
  Format flv
  VideoFrameRate 40
  VideoBitRate 128
  VideoSize 1920x1080
  AVOptionVideo flags +global_header
  AudioBitRate 24
  AudioChannels 2
  AudioSampleRate 44100
  AVOptionAudio flags +global_header
</Stream>

<Stream mp4>
  Feed feed1.ffm
  Format mp4
  VideoFrameRate 40
  VideoBitRate 128
  VideoSize 1920x1080
  AVOptionVideo flags +global_header
  AudioBitRate 24
  AudioChannels 2
  AudioSampleRate 44100
  AVOptionAudio flags +global_header
</Stream>

<Stream avi>
  Feed feed1.ffm
  Format avi
  VideoFrameRate 40
  VideoBitRate 128
  VideoSize 1920x1080
  AVOptionVideo flags +global_header
  AudioBitRate 24
  AudioChannels 2
  AudioSampleRate 44100
  AVOptionAudio flags +global_header
</Stream>

[Commands]

$ ffserver -d -f /etc/ffserver.conf

$ ffmpeg -i MY_RTP_SOURCE  http://localhost:8090/feed1.ffm <http://localhost:8090/feed1.ffm>
