8 ways to stop IPTV streaming video encoder keeps freezing problem

When first time use the encoder, the video picture screaming freeze very often. For example , the image play normal for few seconds, and next few seconds, the encoder freezing , just like a image lost .
So you may find many people search encoder freeze problem in google or forum as below.

All the streaming encoder freezing problems can be solved by FMUSER.
Now FMUSER summarize some reasons that will lead the video streaming freeze , hope to help you solve the problems.

1. The output FPS is bigger than the input FPS
When a DVD output is 1920 * 1080 @ 30 and input this to the encoder, but you set the encoder 1920 * 1080 @ 60 output , the streaming video will be freeze.
Because the encoder can not create extra FPS for you.
Solution: Set the encoder output FPS the same as the DVD FPS or smaller than the DVD FPS.

2. Output resolution and FPS is bigger than the encoder’s workload
For example, FBE200 encoder maximum output resolution and FPS is 1920 * 1080 @ 40, but you set it to work in 1920 * 1080 @ 60, then the encoder freezes. Because it has been beyond its workload.
Solution: Set the output resolution and FPS below encoder’s maximum workload. Such as 1280 * 720 @ 60 or 1920 * 1080 @ 40

3. GOP is not a multiple of the FPS
When FPS is 60, but the GOP is 190 or 25, it will cause iptv encoder freezing.
**Solution:**When FPS is 60, please set the GOP to 30 or 60.

4. Output bit rate exceeds the network workload
Not all switches and routers support all kinds of streaming. For example, some UBNT wireless bridge can not support UDP streaming , so streaming video keeps freezing.
Solution: Connecting the FBE204 IPTV encoder directly to the computer to confirm whether is the problem of the network equipment.

5. Encoder burst streaming exceeds network load
Working encoder will adjust the bit rate compression and output according to the video dynamics. Sometimes output is 2mbps, but it will output 8mbps when at peak. So if your encoder uplink bandwidth is only 4mbps, streaming videos freeze.
Solution: At Bitrate ctrl: CBR / VBR option, try to choose CBR . Another solution is increasing your uplink bandwidth network.

6. Audio sample (hz) changing constantly
There are some DVD players, the output audio sample (hz) 44.1K on the boot screen, but output Audio sample (hz) 48K when the video is playing, it will also lead encoder freezing.
Solution: Convert the FMUSER video streaming encoder playing audio sample (hz) to make them as consistent as possible.

7. Decoder CPU capacity is insufficient
All the decoders have limited decoding capability. It may not be able to accept 1920 * 1080 @ 60 video streaming . So the stream freeze.
When we use VLC test the FBE200 encoder, we also found that some Lenovo notebook using i3 or G series CPU, the CPU workload is too large, it can not normally decode 1920 * 1080 @ 60 video streaming, we only see the freezing video. In fact, this is because of the CPU usage has reached 99%.
Solution: Setting streaming encoder output to make it fit the the decoder usage. For example, change 1920 * 1080 @ 60 to 1280 * 720 @ 40

8. Change MTU to 1400
In some areas, the size of the network packets is limited to 1500, and some areas are limited to 1480.
If you limit the 1480 to the area, the encoder packets is limited to 1500, then it will be freezing.

So, you may try to set the encoder packets to 1400, so that it will not exceed the limitations of the network.

Input device, encoder settings, network equipment and computer equipment , all these will cause the Video stream freeze . When encoder freeze, please do not be nervous, we can check all the equipments and setting, then will be able to solve all the problems . —By FMUSER TEAM.

buonasera,poteri per favore contattare qualche essere umano per delle delucidazioni?

Good evening, please contact some human being for clarification?


9. Encoder / Switch / Decoder Network Interface in different Mode (10M / 100M / 1000M)

If the encoder Network Interface is 1000Mbps, And the decoder is 10mbps.
You will get a terrible video.

So, You need to find out the decoder Network Interface mode is 10m or 100m or 1000m.
And you need to set the encoder Network Interface mode just equal to decoder and switch.
Some swithc have a managerment to see what is it working mode now.
