Question

我开发了一个应用程序，它从文件中获取数据并向每个帧添加元数据，并通过rtp上的udp将数据传输到客户端。

在接收端，客户端会删除该元数据，并且必须播放该视频。

因为我在服务器端使用了

pipeline1 :: gst-launch-1.0 filesrc ! videoparse ! appsink

在appsink上添加元数据并将该缓冲区推送到appsrc。

pipeline 2 :: gst-launch-1.0 appsrc ! rtpgstpay ! udpsink

在Receivers end ::

pipeline1 :: gst-launch-1.0 udpsrc ! rtpgstdepay ! appsink

在appsink上删除元数据并将缓冲区推送到appsrc。

pipeline2 :: gst-launch-1.0 appsrc ! videoparse ! autovideoconvert ! autovideosink

问题是在接收器端，我没有得到所有帧，视频也没有正常播放。只有一帧播放和停止，再次只播放单帧。

任何人都可以提供一些解决方案或建议吗？

服务器端处理帧的

/ *代码* /

/* This is in Function which is called by g_timeout_add_seconds(0, new_sample, NULL);

g_signal_emit_by_name(sink, "pull-sample", &sample, NULL);
buf = gst_buffer_new_wrapped(&header, sizeof(header)); // header is Structure
FrameBuffer = gst_sample_get_buffer(sample);
buffer = gst_buffer_append(buf, FrameBuffer);

g_signal_emit_by_name (appsrc2, "push-buffer", buffer, &ret);

        if(ret != GST_FLOW_OK)
        {
                g_printerr("Failed to Push Buffer");
                return FALSE;
        }
        g_print("Successfully Pushed..\n");

/* Above code is for processing frame at server end. */
