Hi All, Am trying to stream the MPEG video on html5 canvas tag.
I was able to stream my Web CAM video in browser (canvas video tag) with below command. (No errors & good quality) # ffmpeg -s 640x480 -f video4linux2 -i /dev/video0 -f mpeg1video -b 800k -r 30 *http://192.168.1.11:8082/url/640/480/ <http://192.168.1.11:8082/url/640/480/>* I was also able to stream VP8 (webm) file in browser with below command. ffmpeg -vcodec libvpx -i output2.webm -f mpeg1video -b: 400k -r 25 *http://192.168.1.11:8082/url/640/480/ <http://192.168.1.11:8082/url/640/480/>* When i try to stream video from active RTP channel, Transcode steps: -> Read RTP from socket, decode from vp8 codec to native/raw rtp. -> Encode it to mpeg1video frames. -> And send the frame through socket (webserver). Note: Here am handling video stream only, as i don't have other streams like audio or data. Am getting below errors, *# ffmpeg -vcodec vp8 -i rtp://192.168.1.93:15000 <http://192.168.1.93:15000> -f mpeg1video -b: 400k -r 25 http://192.168.1.11:8082/url/640/480/ <http://192.168.1.11:8082/url/640/480/>* ffmpeg version n2.5.6-3-ga2ad7fd Copyright (c) 2000-2015 the FFmpeg developers built on May 1 2015 13:18:01 with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-11) configuration: --enable-nonfree --enable-gpl --enable-libvpx --enable-decoder=aac --enable-libx264 --enable-demuxer=mov --enable-x11grab --enable-zlib --enable-protocol=http --enable-filter=aformat --enable-filter=volume --enable-filter=aresample --prefix=/usr/ --libdir=/usr/lib64/ libavutil 54. 15.100 / 54. 15.100 libavcodec 56. 13.100 / 56. 13.100 libavformat 56. 15.102 / 56. 15.102 libavdevice 56. 3.100 / 56. 3.100 libavfilter 5. 2.103 / 5. 2.103 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 3.100 / 53. 3.100 [rtp @ 0x25cf0e0] Unable to receive RTP payload type 100 without an SDP file describing it Input #0, rtp, from 'rtp://192.168.1.93:15000': Duration: N/A, bitrate: N/A Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 ( http://192.168.1.11:8082/url/640/480/) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream. Output #0, mpeg1video, to 'http://192.168.1.11:8082/url/640/480/': ffmpeg is reading rtp and detecting payload value (VP8 = 100), i try to provide sdp file with *-sdp_file option * but it is invalid argument. please suggest me, how to resolve these errors.
