Hello all! I've recently came across an issue with publishing RTMP (librtmp). Publishing was just stopping after some time. I found a bug in the code, made a patch, and now it works fine. I'd like to share this patch with everyone. How do I do that? Thanks! Viktor

Memory leak in rtmpdump.c
by Reijo Tomperi 21 Jun '11

21 Jun '11

Hi, In rtmpdump.c around line 476 in Download() function there is return RD_SUCCESS; which does not free memory from "buffer" which is allocated at the start of the function and never used after that. This is most likely a minor issue, but I thought reporting it anyway as it can be fixed with a simple free() call (or by moving allocation where memory is actualy used). -- Reijo

librtmp/dh.h MDH_free(vp) using uninitialized pointer
by Reijo Tomperi 21 Jun '11

21 Jun '11

Hi, In file librtmp/dh.h, in function DHInit() there is this code: failed: if (dh) MDH_free(dh); In the same file there is also (this is on a single line): #define MDH_free(vp) {MDH *dh = vp; dhm_free(&dh->ctx); MP_free(dh->p); MP_free(dh->g); MP_free(dh->pub_key); MP_free(dh->priv_key); free(dh);} When this macro is written open, it will generate code that looks like this: MDH *dh = dh; As you can see from the example program from below, this will result dh being uninitialized pointer. -------------- code start ------------------- #include <stdio.h> #define MDH_free(vp) {int *aa = vp; printf("%d\n", *aa ); } #define MDH_free2(vp) {int *ab = vp; printf("%d\n", *ab ); } int main() { int a = 6; int *aa = &a; printf("%d\n", *aa ); MDH_free(aa) MDH_free2(aa) return 0; } -------------- code end ------------------- Program output: 6 -1991643855 6 -- Reijo

Fwd: About librtmp for AudioStream
by Ömer Düzyol 17 Jun '11

---------- Forwarded message ---------- From: Ömer Düzyol <omerduzyol(a)gmail.com> Date: Mon, Jun 13, 2011 at 6:00 PM Subject: About librtmp for AudioStream To: projects(a)mplayerhq.hu, contact(a)xbmc.org Hi, I'm using your rtmpdump and librtmp to stream rtmp audio sources in my iOS project . But, I need to extract audio bytes in chunk and push audio data to Apple's AudioQueue to decode sound in realtime. My rtmp sources serves FLV data and contains only m4a audio. I inspected all the source and I found an abstract "HandleAudio", "HandleVideo" methods in the librtmp's source. static void *HandleAudio*(RTMP *r, const RTMPPacket *packet); I tried to save *packet->m_body* chunks in a file but it doesnt play. But when I save the stream output like rtmpdump, it produces FLV file and VLC player can play the file correctly. How can I parse m4a audio bytes in chunked FLV stream without saving all data? Thanks a lot, Omer

Bug Report.

Hi I've been downloading files from moshcam. Here are two examples:- ___http://www.moshcam.com/the-pretenders/enmore-theatre-849.aspx# ___http://www.moshcam.com/propagandhi/metro-theatre-495.aspx When I use RTMPDump-v2.3 the files download OK. When I use RTMPDump-v2.3 r569 I get errors. Like this:- WARNING: No application or playpath in URL! Connecting ... INFO: Connected... ERROR: rtmp server sent error ERROR: rtmp server requested close I've been advised that this 'bug' appeared in RTMPDump-v2.3 r562. Is there a way to fix this in SVN without breaking anything else?
