scale error code:870, mean:Error number 870 occurred

你好，我这边使用glReadPixels抓取的一帧数据， int width = 1920; int height = 870; int frameRate = 60; int fmt_size = sizeof(unsigned char) * 4; int row_size = width * fmt_size; int bufferSize = width * height * fmt_size * 2; HANDLE hEvent; unsigned char *_data; unsigned char *_tmpdata = new unsigned char[bufferSize]; glReadPixels(0, 0, width, height, GL_RGBA, GL_UNSIGNED_BYTE /0x8035/, _tmpdata); for (int i = 0; i < height; i++) { memcpy(&_data[i * row_size], &_tmpdata[(height - i - 1) * row_size], row_size); }

	EncoderManager::getInstance().encode(_tmpdata, width, height);

先进行转换YUV， scale时报错了。 传入的宽高是一个固定的值： 1920*870， 帮给看看

AVFrame *EncoderManager::toAVFrame(unsigned char *data, int width, int height) { AVFrame *avFrame = av_frame_alloc();

av_image_alloc(avFrame->data, avFrame->linesize, width, height, encoder->getCodecContext()->pix_fmt, 1);

std::int32_t row_pitch {}; row_pitch = width * 4; const int linessizes[2] { row_pitch, 0 }; const uint8_t *tmp[2] = { (uint8_t *)data, NULL }; SwsContext *sws = sws_getContext(width, height, AV_PIX_FMT_RGBA, width, height, AV_PIX_FMT_YUV420P, SWS_FAST_BILINEAR, NULL, NULL, NULL); int ret = sws_scale(sws, tmp, linessizes, 0, encoder->getCodecContext()->height, avFrame->data, avFrame->linesize); printfString("toAVFrame scale", ret); return avFrame; }
