hi All,
I got the error when I using vlc to connect ffserver to get video stream,
the video data is from usb webcam.
video stream will stop when the error is occur
the ffserver conf:
<Stream test.mjpeg>
Feed feed1.ffm
Format mjpeg
VideoSize 640x480
VideoFrameRate 30
VideoCodec mjpeg
Noaudio
</Stream>
ffserver command :
ffserver -f /etc/ffserver.conf &
ffmpeg command:
ffmpeg -f video4linux2 -r 30 -s 640x480 -input_format mjpeg -i /dev/video0
-vcodec copy http://localhost:8090/feed1.ffm
the output log:

==================================================
ffmpeg seems keep running,
but no any video data output by ffserver,
the "invalid stream index" is print out from
/libavformat/fmdec.c, function ffm_read_packet(),
and I also get the error,
function ffm_read_packet(),
case READ_DATA:
size = AV_RB24(ffm->header + 2);
the value of size is very very large, then ffm_is_avail_data() will return
EAGAIN,
such that there is no any video data can be output.
Does anyone have idea?
Any input is very appreciated!
Best Regards,
Soho
