Record to FLV?

[mertyildiran]

Is it possible to record in FLV format? I would like to record in FLV format because if something goes wrong and MP4 does not finish properly then it becomes corrupted:

FLV format does not have such a problem.

[mertyildiran]

By looking this file I can say FLV format is not supported. Could we add FLV support to this library?

[illuspas]

Look at the dev branch, native support for FLV record. Will be merged into the mainline in the future

[mertyildiran]

@illuspas I sent this PR but it become redundant then :blush:

If you are talking about this merge then I cannot see anything related to recording on there. Don't we need a flv: true option in config? I have added that with my PR. Do you want me to send that PR into dev branch?

[illuspas]

This feature should be more comprehensive, like nginx-rtmp record function is configurable. I don't have much free time these days. Maybe you can do it 😄

[mertyildiran]

@illuspas yeah, I have some experience on nginx-rtmp. I'm using my PR on an application and it works just fine. What else should I implement to make it more comprehensive? If you explain a little bit more in detail then I can add the necessary code blocks for you.

Do you want a more configurable recording functionality like in nginx-rtmp#Record? Like recording only audio, keyframes or specifying a file name pattern? Please list the features and I will try to implement them.
