OBS VS SmartPublisher VS Flash Media Live Encoder

OBS

Powerful, it has almost any scene you want, and it’s easy to use. The desktop, camera, and application window can be pushed to the streaming media server through RTMP.

Of course, if you are a developer, want to do secondary development based on OBS, to achieve secondary production, relatively difficult, OBS code volume is very large, it is very difficult to control, if there are bugs, tracking up is very tired.

SmartPublisher

SmartPublisher is the RTMP push stream SDK of Daniu Live SDK (Github). It is cross-platform and supports Windows, Android and iOS platforms. It is especially developed for traditional scenes such as online education and conference with the same screen. For example, it supports video recording, snapshot, external original YUV/RGB data access, or post-coded data integration, which is relatively easy to integrate. Windows platform provides C++ and C# interface externally, Android provides JNI interface, and iOS platform provides Object C interface call.

Function support

If not specified separately, it is supported by Windows, Android and iOS platforms.

• [Video collection and processing] The Windows platform includes the Windows VIDEO collection and processing SDK.
• [Audio collection and processing] The Windows platform includes the Windows Audio collection and processing SDK.
• [Local preview]Windows supports real-time preview of camera, screen, and composite data. Android and iOS support local front and rear camera preview.
• [Camera inversion/rotation]Windows platform supports camera horizontal reversal, vertical reversal, 0°/90°/180°/270° rotation;
• [Camera capture] In addition to the conventional YUV format, Windows platform also supports MJPEG format camera capture;
• [Microphone/speaker acquisition]Windows platform audio input side supports microphone, speaker, or microphone and speaker mix input;
• [RTMP push stream] Ultra-low latency RTMP protocol live push stream SDK (Windows/Android/iOS support RTMP extension H.265 push);
• Windows/Android platforms support H.264/H.265 encoding (Hard coding Android H.265), iOS platforms support H.264 encoding;
• Windows/Android/iOS platforms support AAC encoding, Windows/Android platforms support Speex encoding;
• [Audio encoding]Windows/Android platform support Speex push, Speex coding quality Settings;
• [Volume adjustment] On Windows and Android platforms, the acquisition terminal supports real-time volume adjustment (in the Mixing mode of Windows platform, the volume of microphone and speaker can be controlled separately).
• [H.264 hardcoding]Windows/Android/iOS platforms support H.264 hardcoding for specific models;
• [H.265 hardcoded]Windows/Android/iOS platforms support H.265 hardcoded;
• [Hardcoding adaptive]Android/iOS platform supports hardcoding adaptive. If it detects that hard coding is not supported, the system automatically switches to soft coding (for iOS, if H.265 hard coding is not supported, the system switches to H.264 hard coding first; if h. 264 soft coding is not supported, the system tries to h. 264 soft coding again).
• [Hard and soft coding parameter configuration] Support GOP interval, frame rate and bit-rate Settings;
• [Soft coding parameter Configuration] Supports soft coding profile, soft coding speed and variable bit rate Settings.
• [Multi-instance push] Supports multi-instance push (for example, push screen/camera and external data simultaneously);
• [RTMP extension H.265]Windows/Android/iOS push SDK supports THE RTMP extension H.265 push, Windows for camera acquisition soft coding, using variable bit rate H.265, bandwidth saving, the effect is close to the traditional H.265 encoding camera, H.265 hard coding is supported on Android and iOS platforms.
• [Horizontal and vertical pushing] Supported on Android/iOS platforms, horizontal and vertical pushing is supported.
• [Multi-resolution support] Supports multiple camera or screen resolution Settings;
• [Windows Screen Push]Windows platform supports screen clipping, window collection, screen/camera data synthesis and other modes of push;
• [Screen push on mobile terminal]Android platform supports background Service push screen (5.0+ version);
• IOS platform support background push screen (based on ReplayKit, requires iOS 10.0+ version);
• [Event callback] Supports real-time callback of various states;
• Windows platform supports text watermarking, PNG watermarking, real-time occlusion, Android platform supports text watermarking, PNG watermarking;
• [RTMP push mode] supports RTMP push live | record mode setting (server support required);
• [Mirroring]Android and iOS platforms support the real-time mirroring function of the front camera.
• [Real-time switching between front and rear cameras]Android and iOS platforms support switching between front and rear cameras during collection.
• [Complex network processing] Automatic adaptation of various network environments such as disconnection and reconnection;
• [Dynamic bit rate] Supports automatic adjustment of stream bit rate according to network conditions.
• [Real-time mute] Supports real-time mute/unmute during push.
• [Real-time snapshot] Supports real-time snapshot in the process of pushing flow.
• [Pure audio push stream] support only to collect audio stream and push stream function;
• [Pure video Streaming] Supports pure video streaming in special scenarios;
• [Noise reduction]Windows/Android platform supports noise reduction, automatic gain and VAD detection caused by ambient sound and mobile phone interference.
• Echo cancellation Android platform supports real-time transmission of remote PCM data, convenient echo cancellation processing;
• [Video data interconnection before external coding] YUV data interconnection;
• [Audio data docking before external coding] support PCM docking;
• [Video data docking after external encoding] Supports external H.264 data docking;
• External AAC/PCMA/PCMU/SPEEX data connection;
• [Hibernation setting of push side]Windows platform supports hibernation interface (CPU will be lowered properly after hibernation mode is set).
• [Encoded data output] The Android platform supports the output of encoded H264/AAC data to the upper layer for easy interconnection with third-party platforms (such as GB28181).
• [Extended video function] Perfectly supports combined use of video SDK, video related functions, see “Windows/Android/iOS video SDK”;
• [Clipping mode]Android/iOS platforms support camera clipping mode setting with specific resolution;
• [Server compatibility] Supports self-built servers (such as Nginx and SRS) or CDN.
