• Flash Media Live Encoder does not work with devices having square brackets in their name (#2278916).
• Flash Media Live Encoder crashes due to excessive rebuffering (#2280609).
• If device does not support selected fps value then change the selected value to the nearest supported value (#2300376).
• Flash Media Live Encoder crashes on Vista while capturing audio from Realtek HD Audio device (#2264260).

• Server-side action script is required for DVR feature to work (#2337330).
• When publishing multiple streams and passing parameters in the querystring, the string before the '?' is the stream name and must be unique (# 2251667).
• Decimal values of reconnect interval are truncated (# 1934035)
• Profile validation stops /t and /l options to take precedence over incorrect profile values. Workaround is to rectify the profile values or use /d option and ignore the warning messages (# 1937779)
• To use saved profiles of Flash Media Live Encoder 2.5 in command-line version of Flash Media Live Encoder 3.0, use /d command.
• If the fps selected in Flash Media Live Encoder is not supported by device, the device will send data only at the supported frame rate. This could increase the data rate of H264 encoding process (#1394051, #1689730)
• Local F4V files greater than 2 GB may not be playable. This however does not impact streaming. (# 1669801)
• Virtual memory used by Flash Media Live Encoder increases continuously at the time of reconnection in command line. This happens only when the command window is in "insert" mode and it is clicked somewhere. Again clicking anywhere in the command window stops the memory increase.(# 1709609)
• For H.264 video, Flash Player can buffer up to 64 frames before video starts playing. This may result in buffer length increase in Flash Player. Increase in buffer length may vary depending upon the fps selected in Flash Media Live Encoder (# 1699559)
• Stream might have significant latency if the audio or video device sends incorrect data. High CPU usage is one of factors which could lead to this behavior of the device. (# 1699546, # 1699552)
• Video Stalling may be observed when the CPU usage goes beyond 75%. (# 1641467)
• At higher video sizes it's not possible to completely remove the "interlacing effect" using the deinterlace filter (# 1663753)
• Playback stops if Flash Media Live Encoder stops audio/video streaming and starts only video streaming. Workaround is to start the Flash Player again.(# 1609984)
• In Remote Desktop Connection(RDC) mode
  • DirectShow is not able to enumerate audio devices on remote machine when "Bring to this computer" option is chosen over "Leave at remote computer" option available under 'local resource' tab.(# 1538907)
  • DivX codec may interfere with normal functioning of Flash Media Live Encoder. (# 1688687)
  • Video preview colors are not the same as sent by device, but the encoded stream and file have the same colors as sent by the device. It's better to use command line while using Flash Media Live Encoder in RDC mode. (# 1569479, # 1607271)
• When encoding is going on and the system goes into sleep/standby mode, removing the capture device from the system could cause Flash Media Live Encoder to behave improperly. No such issue is observed when the user is logged in or if the system is locked. (# 1605063)
• Flash Media Live Encoder's subscriber will have audio distortions/missing audio if buffer size in Subscriber is 0. Workaround is to keep the buffer size >= 0.1 (# 1565882, #1632999, #1654044, #1641071)
