Hi. I have setup VLC to transcode an rtmp stream for rtsp delivery using the following command:

vlc rtmp://mydomain/live/demo -I dummy --sout "#transcode{vcodec=h264,vb=2048,fps=15,scale=1,venc=x264{preset=ultrafast,tune=zerolatency,aud,profile=baseline,level=30,keyint=15,bframes=0,ref=1,nocabac},acodec=mp4a,ab=128,channels=2,samplerate=44100,audio-sync}:rtp{sdp=rtsp://:5544/test}" --rtsp-timeout=-1 --no-sout-rtp-sap --no-sout-standard-sap --ttl=1 --sout-keep

Which seems to work however two things happen (btw, im using v2.1.0-git win7 for the server), the first is that the client disconnects at varying times, sometimes within a few seconds others a few minutes (using VLC v1.1.12 osx for the client).

Here is the server output:

The second issue is that on occasion (quite frequently) the server will fail with an exception

Code: Select all

x264 [error]: malloc of size 4966163 failed
[0x63f2e60] x264 encoder error: cannot open x264 encoder
unhandled vlc exception

Any Ideas? Thanks!

-- Part 2 --

I am using Flash Media Encoder and realized that I do not even need to do the transcode since my client (Android) can decode the same codecs being spit out of FME, which means I simply need to convert the RTMP stream to RTSP. I modified my command line to this:

Code: Select all

vlc rtmp://mydomain/live/demo --sout "#rtp{sdp=rtsp://:5544/test}" --rtsp-timeout=-1 --no-sout-rtp-sap --no-sout-standard-sap --ttl=1 --sout-keep

I am still getting the disconnects which seem to happen much later, a few minutes later. I have seen various server reactions, the first is this:

Code: Select all

Where the last line keeps printing indefinitely.

Another is this:

[0x30103e0] main input error: ES_OUT_RESET_PCR called

Where the client was disconnected and the server just sits on that last line.

And finally another like this:

Code: Select all

Where the last 3 lines get repeated over and over.
