Docs/Migration: 1.x → 2.x breaking API changes are not documented (package rename, ConnectChecker rename)

[MikalaiKryvusha]

Summary

RootEncoder 2.x introduced significant breaking changes to the public API compared to 1.x. These changes are not reflected in the README or a migration guide, which makes upgrading unnecessarily painful. This issue documents what changed and requests a migration guide.

Affected versions

Migrating from library:1.x → library:2.4.7

Breaking changes discovered

1. Package rename for streaming classes

1.x	2.x
com.pedro.rtplibrary.rtmp.RtmpCamera1	com.pedro.library.rtmp.RtmpCamera1
com.pedro.rtplibrary.rtsp.RtspCamera1	com.pedro.library.rtsp.RtspCamera1

2. ConnectCheckerRtmp replaced by ConnectChecker

1.x	2.x
com.pedro.rtmp.utils.ConnectCheckerRtmp	com.pedro.common.ConnectChecker

3. Callback method renames (removed protocol-specific suffixes)

1.x callback	2.x callback
onConnectionSuccessRtmp()	onConnectionSuccess()
onConnectionFailedRtmp(reason)	onConnectionFailed(reason)
onNewBitrateRtmp(bitrate)	onNewBitrate(bitrate) (from BitrateChecker)
onDisconnectRtmp()	onDisconnect()
onAuthErrorRtmp()	onAuthError()
onAuthSuccessRtmp()	onAuthSuccess()
(not present)	onConnectionStarted(url)

4. prepareVideo signature change

// 1.x
boolean prepareVideo(int width, int height, int fps, int bitrate, CameraHelper.Facing facing)

// 2.x
boolean prepareVideo(int width, int height, int fps, int bitrate, int rotation)

5. GlInterface.setCustomImageToStream() / clearCustomImageToStream() removed

In 2.x the static-image injection API was removed. The replacement is to use BaseFilterRender via glInterface.setFilter(...), but there is no documented equivalent for injecting a static bitmap frame.

Request

Please add a MIGRATION.md or a "Migrating from 1.x to 2.x" section in the README. Even a brief table of renames would save users hours of debugging.

Thank you for the great library!
