[Live-devel] FW: Errors on client side when using vlc as media player

[Daniel Labonte]

Hi again,

I believe I solved the errors with the streaming. I changed one command line argument for avconv using -f h264 instead of flv, as the comments in testOnDemandRTSPServer mention h.264 video elementary stream.

I will review the  FAQ to address my next issue; streaming live video, or stream from a pipe.

Regards,
Daniel

Subject: Errors on client side when using vlc as media player

Good afternoon,

my current project involves sampling video transmitted in real-time (in this case a test pattern) and stream these images to be viewed remotely on a client computer.

The environment is a Ubuntu 12.04 64bit machine. Tests were done using a physical server and a virtual machine.

For the current prototype, the captured images are put into an .avi container using openCV, the output being a named pipe (pleoraFIFO.avi).
This avi file is then converted using avconv to produce a H264 format video. The actual command and arguments used is:
    avconv -i ./pleoraFIFO.avi -vcodec libx264 -an  -f flv test.264

The idea is then to stream the file test.264 using live555. I tried different approaches; live555MediaServer, testONDemandRTSPServer,
testH264VideoStreamer and a modified version of testONDemandRTSPServer where only test.264 is streamed. Regardless of the live555
executable used, I am unable to view the video stream on a client.

Note that the file test.264.can be viewed using a media player (totem or vlc) on the server.

I have attached different stats/log information related to test.264 and information reported by testRTSPCLient and openRTSP on the client side.

If vlc is used on the server to stream the video. the following errors are reported:
    vlc test.264 --sout '#rtp{dst=192.168.0.12,port=1234,sdp=rtsp://192.168.129.102:8080/test.sdp}'
    VLC media player 2.0.8 Twoflower (revision 2.0.8a-0-g68cf50b)
    [0x8703f8] logger interface: using logger.
    [0x792108] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
    [0x7f02e00012c8] stream_out_rtp stream out: Consider passing --rtsp-host=IP on the command line instead.
    [flv @ 0x7f0314c1ebc0] Estimating duration from bitrate, this may be inaccurate
    [flv @ 0x7f02e00027a0] Estimating duration from bitrate, this may be inaccurate
    [0x7f02e0c10278] main demux error: option sub-original-fps does not exist
    [0x7f0304000b78] main input error: no suitable demux module for `file/subtitle:///home/builduer/samples/eppGateway//test264.txt'

although the streamed video can be viewed using vlc rtsp on the client side
    vlc rtsp://192.168.129.102:8080/test.sdp

I am confused as to why I experience the reported errors streaming using live555 media server applications and your help/comments are welcome.
I downloaded and build live555 version dated May 27, 2014.

Regards
Daniel
