VTDecompressionSessionDecodeFrame(-12902) error: kVTParamaterErr

Open Tttbkhn opened this issue 5 years ago • 1 comments

Hello, I'm working on a project for IP camera using Websocket (wss protocol). I am trying to decode a h.264 raw frame using avios. In the wss receive method (binary data) I found the SPS [Unit8Array(14)] and PPS [UInt8Array(4)] so I think I was receiving the correct h.264 raw format. But after that, I was having a problem with the status returned by: VTDecompressionSessionDecodeFrame(videoSession, sampleBuffer: sampleBuffer, flags: [._EnableAsynchronousDecompression], frameRefcon: nil, infoFlagsOut: &infoFlags)

The status always return H264Error.VTDecompressionSessionDecodeFrame(-12902). I tried changing the flags but still no working. I have been reading about NAL Unit but I don't have much experience with VTDecompressionSession. I really appreciate for your kind reply.

Here is my implementation of your library:

  1. I create a H264Decoder in viewDidLoad
  2. In the socket received method, i try to decode the h.264 raw frame received.

This is where I found the SPS UInt8 array: [103, 77, 0, 30, 149, 168, 40, 15, 105, 184, 8, 8, 8, 16]

This is where I found the PPS UInt8 array: [104, 238, 60, 128]

This is the UInt8 array I received as a h.264 raw frame: [101, 184, 0, 0, 13, 178, 192, 61, 255, 53, 198, 74, 15, 5, 213, 161, 21, 148, 166, 113, 183, 184, 18, 116, 53, 74, 253, 60, 89, 34, 93, 45,

I was trying to debug but the code will always throw error in VTDecompressionSessionDecodeFrame. I check the videoSession and the sampleBuffer was not null so I don't know which parameter has fault. I am wondering if this is referring to a problem about decompressionOutputCallback because the initVideoSession() method, the line: outputCallback.decompressionOutputCallback = callback as? VTDecompressionOutputCallback is always nil. Maybe the reason is the callback is never called.

For more information this is my callback method.

fileprivate func callback(_ decompressionOutputRefCon: UnsafeMutableRawPointer,
                      sourceFrameRefCon: UnsafeMutableRawPointer,
                      status: OSStatus,
                      infoFlags: VTDecodeInfoFlags,
                      imageBuffer: CVImageBuffer?,
                      presentationTimeStamp: CMTime,
                      presentationDuration: CMTime){
    
    unsafeBitCast(decompressionOutputRefCon, to: H264Decoder.self).decompressionOutputCallback(sourceFrameRefCon, status: status, infoFlags: infoFlags, imageBuffer: imageBuffer, presentationTimeStamp: presentationTimeStamp, presentationDuration: presentationDuration)
}

Hello, I'm working on a project for IP camera using Websocket (wss protocol). I am trying to decode a h.264 raw frame using avios. In the wss receive method (binary data) I found the SPS [Unit8Array(14)] and PPS [UInt8Array(4)] so I think I was receiving the correct h.264 raw format. But after that, I was having a problem with the status returned by: VTDecompressionSessionDecodeFrame(videoSession, sampleBuffer: sampleBuffer, flags: [._EnableAsynchronousDecompression], frameRefcon: nil, infoFlagsOut: &infoFlags)

The status always return H264Error.VTDecompressionSessionDecodeFrame(-12902). I tried changing the flags but still no working. I have been reading about NAL Unit but I don't have much experience with VTDecompressionSession. I really appreciate for your kind reply.

Here is my implementation of your library:

1. I create a H264Decoder in viewDidLoad

2. In the socket received method, i try to decode the h.264 raw frame received.

This is where I found the SPS UInt8 array: [103, 77, 0, 30, 149, 168, 40, 15, 105, 184, 8, 8, 8, 16]

This is where I found the PPS UInt8 array: [104, 238, 60, 128]

This is the UInt8 array I received as a h.264 raw frame: [101, 184, 0, 0, 13, 178, 192, 61, 255, 53, 198, 74, 15, 5, 213, 161, 21, 148, 166, 113, 183, 184, 18, 116, 53, 74, 253, 60, 89, 34, 93, 45,

I was trying to debug but the code will always throw error in VTDecompressionSessionDecodeFrame. I check the videoSession and the sampleBuffer was not null so I don't know which parameter has fault. I am wondering if this is referring to a problem about decompressionOutputCallback because the initVideoSession() method, the line: outputCallback.decompressionOutputCallback = callback as? VTDecompressionOutputCallback is always nil. Maybe the reason is the callback is never called.

For more information this is my callback method.

fileprivate func callback(_ decompressionOutputRefCon: UnsafeMutableRawPointer,
                      sourceFrameRefCon: UnsafeMutableRawPointer,
                      status: OSStatus,
                      infoFlags: VTDecodeInfoFlags,
                      imageBuffer: CVImageBuffer?,
                      presentationTimeStamp: CMTime,
                      presentationDuration: CMTime){
    
    unsafeBitCast(decompressionOutputRefCon, to: H264Decoder.self).decompressionOutputCallback(sourceFrameRefCon, status: status, infoFlags: infoFlags, imageBuffer: imageBuffer, presentationTimeStamp: presentationTimeStamp, presentationDuration: presentationDuration)
}

Raw frame you are provided seems not to be AnnexB. The Annex B specification solves this by requiring ‘Start Codes’ to precede each NALU. A start code is 2 or 3 0x00 bytes followed with a 0x01 byte. e.g. 0x000001 or 0x00000001
