Method Detail

onEnd

public abstract void onEnd(int state)

The callback when the editing is complete.

Parameters:

state - 0 indicates playback the video. 1 indicates export the video.

onError

public abstract void onError(int rv)

The callback when an error occurs.

Parameters:

rv - The error code. VideoPool: ALIVC_FRAMEWORK_MEDIA_POOL_WRONG_STATE indicates that the state is incorrect. ALIVC_FRAMEWORK_DEMUXER_INIT_MULTI_TIMES indicates that DEMUXER is initialized multiple times. ALIVC_FRAMEWORK_DEMUXER_OPEN_FILE_FAILED indicates that an error occurred while starting DEMUXER. ALIVC_FRAMEWORK_DEMUXER_FIND_STREAM_INFO_FAILED indicates that DEMUXER failed to obtain stream information. ALIVC_FRAMEWORK_VIDEO_DECODER_CREATE_DECODER_FAILED indicates that an error occurred while creating the decoder. ALIVC_FRAMEWORK_VIDEO_DECODER_ERROR_STATE indicates that the decoder state is incorrect. ALIVC_FRAMEWORK_VIDEO_DECODER_ERROR_INPUT indicates that the decoder input is incorrect. ALIVC_FRAMEWORK_VIDEO_DECODER_SPS_PPS_NULL indicates that the SPSPPS parameter of the decoder is null. ALIVC_FRAMEWORK_VIDEO_DECODER_CREATE_H264_PARAM_SET_FAILED indicates that an error occurred while creating H264 decoding parameters. ALIVC_FRAMEWORK_VIDEO_DECODER_CREATE_HEVC_PARAM_SET_FAILED indicates that an error occurred while creating HEVC decoding parameters. ALIVC_FRAMEWORK_MEDIA_POOL_CACHE_DATA_SIZE_OVERFLOW indicates that the cache memory is full. AudioPool: ALIVC_FRAMEWORK_MEDIA_POOL_WRONG_STATE indicates that the state is incorrect. ALIVC_FRAMEWORK_DEMUXER_INIT_MULTI_TIMES indicates that DEMUXER is initialized multiple times. ALIVC_FRAMEWORK_DEMUXER_OPEN_FILE_FAILED indicates that an error occurred while starting DEMUXER. ALIVC_FRAMEWORK_DEMUXER_FIND_STREAM_INFO_FAILED indicates that DEMUXER failed to obtain stream information. ALIVC_FRAMEWORK_AUDIO_DECODER_CREATE_DECODER_FAILED indicates that an error occurred while creating the decoder. ALIVC_FRAMEWORK_AUDIO_DECODER_ERROR_STATE indicates that the decoder state is incorrect. ALIVC_FRAMEWORK_AUDIO_DECODER_ERROR_INPUT indicates that the decoder input is incorrect.

onCustomRender

public abstract int onCustomRender(int srcTextureID,
                                   int width,
                                   int height)

The callback that outputs the texture id before adding effects to the video.

Parameters:

srcTextureID - The old texture id.

width - The width of the texture.

height - The height of the texture.

Returns:

The texture id after the rendering.

onTextureRender

public abstract int onTextureRender(int srcTextureID,
                                    int width,
                                    int height)

The callback that outputs the texture id after adding effects to the video.

Parameters:

srcTextureID - The old texture id.

width - The width of the texture.

height - The height of the texture.

Returns:

The texture id after the rendering.

onPlayProgress

public abstract void onPlayProgress(long currentPlayTime,
                                    long currentStreamPlayTime)

The callback that outputs the progress of playback. For example, if the playback of a 10-second video is slowed down to 15 seconds, currentPlayTime=15s and currentStreamPlayTime=10s when the playback reaches the last second.

Parameters:

currentPlayTime - The current time on the playback timeline.

currentStreamPlayTime - The current time on the stream timeline.

onDataReady

public abstract void onDataReady()

The callback when the playback data is ready to use.
