  • Use SDL2 play yuv file but actually no display [closed]

    14 juin 2024, par guan xi

    I use ffmpeg to demux and decode the media file, and then use SDL2 to play the raw data, everything is ok. no error no warning, but SDL2 windows does not dispaly video content.
All i know is frame dts is ordered in SDL2 play queue and data is good.

    


    void VideoPlay::play_video() {
  while (is_running_) {
    refresh_loop_wait_event(&event_);

    switch (event_.type) {
      case SDL_KEYDOWN:
        if (event_.key.keysym.sym == SDLK_q) {
          LOG_INFO("Q quit");
          is_running_ = false;
          frame_queue_->abort();
        }
        break;
      case SDL_QUIT:
        LOG_INFO("SDL_QUIT");
        is_running_ = false;
        frame_queue_->abort();
        break;

      default:
        break;
    }
  }
}

void VideoPlay::refresh_loop_wait_event(SDL_Event *event) {
  SDL_PumpEvents();

  while (
      !SDL_PeepEvents(event, 1, SDL_GETEVENT, SDL_FIRSTEVENT, SDL_LASTEVENT)) {
    video_refresh();
    SDL_PumpEvents();
  }
}

void VideoPlay::video_refresh() {
  int ret = 0;
  frame_queue_->pop(frame_);
  if (!frame_) {
    LOG_ERROR("frame_queue_ pop failed.");
    is_running_ = false;
    frame_queue_->abort();
    return;
  }

  rect_.x = 0;
  rect_.y = 0;
  rect_.w = video_width_;
  rect_.h = video_height_;

  ret = SDL_UpdateYUVTexture(
      texture_, &rect_, frame_->data[0], frame_->linesize[0], frame_->data[1],
      frame_->linesize[1], frame_->data[2], frame_->linesize[2]);

  LOG_DEBUG("frame pts: %ld, tot size: %d, Y size: %d, U size: %d, V size: %d",
            frame_->pts, video_width_ * video_height_, frame_->linesize[0],
            frame_->linesize[1], frame_->linesize[2]);
  if (ret != 0) {
    LOG_ERROR("SDL_UpdateYUVTexture failed. %s", SDL_GetError());
    is_running_ = false;
    frame_queue_->abort();
    return;
  }
  ret = SDL_RenderClear(renderer_);
  if (ret != 0) {
    LOG_ERROR("SDL_RenderClear failed. %s", SDL_GetError());
    is_running_ = false;
    frame_queue_->abort();
    return;
  }
  ret = SDL_RenderCopy(renderer_, texture_, nullptr, &rect_);
  if (ret != 0) {
    LOG_ERROR("SDL_RenderCopy failed. %s", SDL_GetError());
    is_running_ = false;
    frame_queue_->abort();
    return;
  }
  SDL_RenderPresent(renderer_);
  SDL_Delay(10);
  av_frame_free(&frame_);
  frame_ = nullptr;
}
