Question / Help Streaming Service Dependent Skipped Frames

Hows it going everyone,

I have a question regarding skipped frames. From my understanding skipped frames are based on the ability of your CPU handling the set preset on X264. My question is does the streaming service have anything to do with skipped frames? I am able to stream on 1080/60 medium preset on Mixer with no issues, not a single skipped frame during the entire stream. Now the same 1080/60 medium preset on Twitch and it skips frames like crazy. The stream is nearly unwatchable. I am kind of confused on why this is happening. Same Obs settings just different streaming services with two completely different results in quality. This is on a AMD 2700x streaming dedicated pc. Please let me know what you guys think about this.
 
There are different reasons for skipped frames. The most common 3 reasons have their own log entries in the OBS log: skipped frames because of rendering lag - this is due to the GPU having not enough resources to render the output video. Then there are skipped frames because of encoding lag - this is due to the encoder not being able to encode the frames within time. For example, for a 60 fps video each frame has to be encoded in less than 1/60 s=16.6 ms. The third reason is for streaming: skipped frames due to insufficient bandwidth. The data that must be pushed over the network to the streaming provider is more than the network can handle. This is an ISP issue or a streaming provider issue. Usually ISP.

What kind of skipped frame happens for you can be seen if you look into the corresponding OBS logfile.
 
Hey all, bringing this old thread back because i still have the same issue.

Does anyone know if streaming service can cause skipped frames? is it harder to encode to certain streaming services ?

Read the first post of this thread for more details on my issue.

Thanks all!
 
The streaming service would only have an impact on the skipped frames due to your connection to the ingest servers and the bitrate you're trying to send.

It would help if you posted a log file so we could help find the specific issue you're having with encoding lag.
