| Type: | Warning |
| Category: | Video specific |
| Products: | testingRTC, watchRTC, analyzeRTC |
| Message: | Decoded less frames than received (X frames discarded) |
What is this about?
The device decoded less video frames than it received over the network.
What does this look like in the analysis?
If you open testRTC Internals, then for the incoming video channel, you will see that the framesReceived is higher than framesDecoded.
Potential risks
When video frames are being discarded by the receiver, it has the potential of causing serious video quality issues.
Oftentimes, video frames are dependent on one another. Losing a frame will cause all future frames to be useless and require a new keyframe to be generated and sent. This is wasteful on the network and harmful to video quality.
A main reason to drop video frames is lack of available CPU, which causes the device to throttle data and user experience. Better CPU and network management is needed to avoid such cases.
Suggested actions to take
