<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I have been using the ffmpeg libraries (libavcodec, libavformat, etc.) to encode buffer data retrieved from camera/microphone and stream it over the network to a destination IP address using MPEG-TS and UDP. The encoding
and streaming works perfectly, however I seem to encounter a problem with the “av_write_frame” function which is used to write the encoded packet to the output media.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">After a seemingly random period of time, the “av_write_frame” function returns the following error:

<p class="MsoNormal"><span lang="EN-US">Streamer.dll is the C# wrapper I wrote to communicate with the C++ libraries of ffmpeg. This error sometimes occurs after a few minutes of streaming, other times after a much longer period (10-30 minutes). Also, this
error occurs at both video and audio encoding, so I haven’t been able to pinpoint the exact reason behind this problem. Unfortunately my application crashes every time this error occurs, so it is quite frustrating.<o:p></o:p></span></p>
