Hi All, I use ffmpeg + ffserver to support a stream server. but there is a big problem when Audio + video. both audio and video are use "stream copy" option. I can use ffplay to play the rtp stream by the url "rtsp:// 192.168.1.254:5554/test1-rtsp.mpg"
the conf of ffserver is : <Stream test1-rtsp.mpg> Feed feed2.ffm Format rtp AVOptionVideo flags +global_header VideoSize 1280x720 VideoFrameRate 30 VideoCodec libx264 AVOptionAudio flags +global_header AudioCodec pcm_s16be AudioChannels 2 AudioSampleRate 48000 </Stream> the ffmpeg command is : ffmpeg -sn -f video4linux2 -r 30 -s 1280x720 -input_format h264 -i /dev/video1 -f alsa -ar 48000 -ac 2 -i hw:0 -vcodec copy -acodec copy -map 0:0 -map 1:0 http://localhost:8090/feed2.ffm Audio is played earlier than video about 3~5 seonds or more than 5 seconds. why Audio will be playied for a few seconds? I can see , ffmpeg capture the data from USB webcam and USB sound card by interleaved Is there any option can be used for fine tune ? Any input is very appreciated!!!
