C++ (Cpp) doEncode Examples

Example #1

File: AudioEncode.cpp Project: Tomi-H/media-convert

int AudioEncode::encode(AVPacket * pkt, const uint8_t ** data, int nb_samples)
{
    if (mBitRate == 0)
        mBitRate = defaultBitRate();

    if (mChannelLayout == 0) {
        mChannelLayout = defaultChannelLayout();
    } else {
        mChannelLayout = checkChannelLayout(mChannelLayout);
    }

    if (mSampleFmt == AV_SAMPLE_FMT_NONE) {
        mSampleFmt = defaultSampleFmt();
    } else {
        mSampleFmt = checkSampleFmt(mSampleFmt);
    }

    if (mSampleRate == 0)
        mSampleRate = defaultSampleRate();

    mCodecCtx->bit_rate = mBitRate;
    mCodecCtx->channel_layout = mChannelLayout;
    mCodecCtx->sample_fmt = mSampleFmt;
    mCodecCtx->sample_rate = mSampleRate;
    mCodecCtx->flags |= mFlags;
    if (!avcodec_is_open(mCodecCtx)) {
        avcodec_open2(mCodecCtx, mCodec, NULL);
    }
    mState = ENCODE_STATE_RUN;

    return doEncode(pkt, data, nb_samples);
}

Example #2

File: vaapiencoder_base.cpp Project: keqiaox/libyami

Encode_Status VaapiEncoderBase::encode(const SharedPtr<VideoFrame>& frame)
{
    if (!frame || !frame->surface)
        return ENCODE_INVALID_PARAMS;
    if (isBusy())
        return ENCODE_IS_BUSY;
    SurfacePtr surface = createSurface(frame);
    if (!surface)
        return ENCODE_INVALID_PARAMS;
    return doEncode(surface, frame->timeStamp, frame->flags & VIDEO_FRAME_FLAGS_KEY);
}

Example #3

File: vaapiencoder_base.cpp Project: keqiaox/libyami

Encode_Status VaapiEncoderBase::encode(VideoFrameRawData* frame)
{
    if (!frame || !frame->width || !frame->height || !frame->fourcc)
        return ENCODE_INVALID_PARAMS;

    FUNC_ENTER();

    if (isBusy())

    SurfacePtr surface = createSurface(frame);
    if (!surface)
        return ENCODE_NO_MEMORY;
    return doEncode(surface, frame->timeStamp, frame->flags & VIDEO_FRAME_FLAGS_KEY);
}

Example #4

File: rlc.cpp Project: imssbc/irena

{
	m_timer.start();
	doEncode(pImg, pBstr);
	m_timer.stop();
}
