gop, keyframes

[nikitapilgrim]

Can I change this setting (keyframes)? I need to set it from 2-8 sec

[ThibaultBee]

Hi, There is no way to set the gop size in the API yet. Why would you need these requirements?

[nikitapilgrim]

your library can be used for a custom server. It would be great if you could pass more options

[ThibaultBee]

yeah, but an increase of the gop means that if you lost a packet at the beginning of the gop (packet loss is likely to happen in live streaming), the live stream will be altered for up to X seconds which can be a long period. 8 seconds is a long period for a viewer. So, we don't understand why you require to increase gop size. We need to understand the use case and the reason behind this before adding such settings.

I can't use this library with different services right now because I can't change the keyframe to at least 2 seconds

[nikitapilgrim]

I would be very grateful if you could implement this or suggest an alternative

[ThibaultBee]

A gop of 2s is a recommended settings for these platform not a requirement. Right? For which services are you stuck?

I have this problem with cloudflare live stream

Stream supports a maximum ingest bitrate of 12000 Kbps. You must set GOP durationOpen external link (keyframe interval) of between 2 to 10 seconds. The default in most encoding software, including Open Broadcaster Software (OBS), is within this range. Setting a lower GOP duration will reduce latency for viewers, while also reducing encoding efficiency. Setting a higher GOP duration will improve encoding efficiency, while increasing latency for viewers. This is a tradeoff inherent to video encoding, and not a limitation of Cloudflare Stream. Closed GOPs are required. This means that if there are any B frames in the video, they should always refer to frames within the same GOP. This setting is default in most encoding software such as OBS. Stream Live only supports H.264 video and AAC audio codecs as inputs. This requirement does not apply to inputs that are relayed to Stream Connect outputs. Stream Live supports ADTS but does not presently support LATM.

Hi,

A parameter gopDuration has been added to the native dependencies:

• https://github.com/apivideo/api.video-ios-live-stream
• https://github.com/apivideo/api.video-android-live-stream

It will be integrated in the RN part soon.

I just added a gopDuration param in the video object. Could you that this issue is fixed in the main branch?

Yes it works. Only for some reason there is no sound :( But the video shows as it should

Can you tell me if this could be a problem?

On Android or iOS?

No, it should not.

[ThibaultBee]

The reason you have issue with the audio stream is that the audio is muted by default due to a regression. Thanks for noticing.

[ThibaultBee]

Could you retest on the main branch?

[nikitapilgrim]

Yes there is sound now. And the camera starts quickly

[ThibaultBee]

This should be fixed in v1.2.2.
