360 video unity recorder meeting oculus tv specs
Hi, I have a VR scene in unity, aka a 3D world in unity. I filmed it in 360 with my unity recorder. However it saying the 'video cant be played because the file is corrupt'. Here is an image. I opened up the dev tools on my firefox browser and looked at the console it. It gave the errors: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://graph.oculus.com/video_upload_transfer?access_token=OCAeORB8DCsxiGxUczXa05PeloWUMXGT2NICUgqeue0ZCcacAEb56H7qxzVVGVS26WKpLAxLYGjHZCch1k7ZAvW2WLR73GAEZD&fb_dtsg=NAcOO-_emESTlaTRl2xKpc2OK51nwOU1xp6xBm__Dl33k5JS2FtzcwQ%3A35%3A1656116547&jazoest=25434&lsd=zEE2tPqN9vYzJjVQ4lzgO5.

I am concerned that my unity 360 recording settings did not meet the oculus media specs https://creator.oculus.com/media-studio/documentation/video-spec/ I am pasting my unity recorder settings here as well. Thank you very much to anyone who takes the time to help me with this issue- I am deeply grateful! Thank you, Ozymandias
Android MediaCodec
Hello everyone. In our program, HLS 360video data is decoded using Android MediaCodec and rendered on the Unity. It uses MediaCodec to decode the H264 stream, but it looks very slow in Oculus Quest. And MediaCodec stops decoding after a short while. The following log was displayed in logcat. This content is output every time data is sent using MediaCodec's queueInputBuffer. #gpuaddr changes every time. 2019-08-19 11:51:33.251 685-22216/?

The source code of the part that uses MediaCodec is posted. # Partially omitted. Decoder initialization process. I tried setting #SPS and PPS, and setting other keys to MediaFormat, but the operation did not change. void initDecoder(final byte[] data) throws IOException { MediaFormat mediaFormat; mediaFormat = MediaFormat.createVideoFormat(mime, viewWidth, viewHeight); mediaFormat.setInteger(MediaFormat.KEY_MAX_INPUT_SIZE, viewWidth * viewHeight); try { codec.configure(mediaFormat, null, null, 0); codec.start(); } catch (Exception e) { } } When receiving frame data by streaming, it passes the data to the decoder. boolean decodeFrame(final int iTimestamp, byte[] data) { if (doInit) { try { initDecoder(data); } catch (IOException e) { e.printStackTrace(); } doInit = false; //flgs = MediaCodec.BUFFER_FLAG_CODEC_CONFIG; flgs = MediaCodec.BUFFER_FLAG_KEY_FRAME; } else { flgs = MediaCodec.BUFFER_FLAG_PARTIAL_FRAME; //Tried another flg. But result did not change. } try { final int inputBufIndex = codec.dequeueInputBuffer(1000 * 100); if (inputBufIndex >= 0) { ByteBuffer[] inputBuffers = null; ByteBuffer inputBuf; inputBuf = codec.getInputBuffer(inputBufIndex); inputBuf.put(data); long presentationTimeUs = iTimestamp*1000; codec.queueInputBuffer( inputBufIndex, 0, // offset data.length, presentationTimeUs, flgs ); return true; } } catch (Exception e) { return false; } return false; } This issue has not happened on other Android devices. The same program works fine with Oculus Go, but only Oculus Quest has this problem. Is this a bug specific to Oculus Quest?
High Resolution Video in Quest App
Hello, I am building an Application on Oculus Quest using Unity engine. In the application there is a scene where I play a 360 video of high resolution (5760x2880); I am using render texture of the same size then a I am using the material in the skybox (lighting). yet the resolution of the video decreses. I wonder if there is another way to include high resolution videos in the app without compromising its resolution when built.Can I use OVROverlay to get better 360 video performance?
Hello, I am developing an Oculus GO app in Unity that shows a 360 video player. So far I have been using a VideoPlayer that renders to a RenderTexture and a sphere with the Skybox/Panoramic shader that uses the same RenderTexture. It works great for most videos. But some videos with a lot of motion "flickers". I have a video of a skier going down a hill and every time he passes objects close to the camera the object appears twice. I took a photo of one of the lenses in the GO: As you can see you can clearly see two sticks where it should only be one. And when you actually look into the glasses the effect is even more obvious. I have tested with a 4096x2048 video. But it doesn't seem to matter if I use higher or lower resolution of the videos. I think it is more a limit in the way I render the video to the sphere. Now to the question: So I started reading about the OVROverlay today and when I read the documentation it sounded like this could be used to render videos to a sphere with better performance. I tried to setup a scene with an OVROverlay and a video player but I couldn't get it to work in the Oculus GO. I used the SampleFramework 180 degrees video player as a source. But I couldn't get that sample code to run on my GO at all. Has anyone used an OVROverlay to render 360 videos?
