Seek in rtmpgw
by Peter Vicman 07 Dec '10

07 Dec '10

Hi all, I already make one post to stream-recorder.com forum but I decided to post on mailing list too. I'm working on a code for rtmpgw program to add seek-ing support on a current rtmp stream. I'm using function call RTMP_SendSeek() but it doesn't work as expected. The VLC client just disconnects when it's buffer become empty. But I noticed that if I drop few received packets got with RTMP_Read() from server after I call Seek, the VLC plays fine at the requested position and stream continues. So the question is: what I'm doing wrong? What is the correct way of using RTMP_SendSeek? Strange thing is that function call RTMP_Pause() for pausing using in the same way works as expected. Thanks for any useful info. Peter

Having problem when playing a live cam with librtmp
by Mahmut Akcay 02 Dec '10

I'm trying to use ffmpeg with librtmp to play a live cam with no luck. It keeps logging *RTMP_ReadPacket: fd=7* on the console. However, rtmpdump works fine with the same url. Am I missing anyting when using librtmp? For rtmpdump, I use the following which works fine: rtmpdump -r rtmp://212.175.65.69/live -a live -y BQWERTM -v -o output.flv For ffmpeg with librtmp (v2.3): ffplay "rtmp://212.175.65.69:1935/live/BQWERTM live=1" -debug 5 and got the following on the console: FFplay version SVN-r25775, Copyright (c) 2003-2010 the FFmpeg developers built on Nov 21 2010 08:30:21 with gcc 4.2.1 (Apple Inc. build 5664) configuration: --enable-librtmp --disable-encoders --disable-yasm --arch=x86_64 libavutil 50.33. 0 / 50.33. 0 libavcore 0.13. 0 / 0.13. 0 libavcodec 52.96. 0 / 52.96. 0 libavformat 52.84. 0 / 52.84. 0 libavdevice 52. 2. 2 / 52. 2. 2 libavfilter 1.62. 0 / 1.62. 0 libswscale 0.12. 0 / 0.12. 0 Parsing...

Request - settable Windows application title
by gxdata 01 Dec '10

01 Dec '10

It would be useful for the Windows version to have a parameter that allows the application title to be set by the calling program. I have been trying with SendMessage(hWnd, WM_SETTEXT, "some text") but without success. Is this the appropriate forum to contact those who do the rtmpdump compile for Windows? Thanks Ian Thomas Scientific Software
