How can I turn a series of images into a video using JCodec?

问题 I'm trying to use JCodec to turn a series of images into a video inside of a Java SE desktop application. The few methods I've tried all resulted in a video that Windows Media Player could not play. It is unclear to me if this is a codec issue (doubtful) or if I'm not creating the video properly. When I try to play the video in Windows Media Player I get: Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to

问题 I'm trying to decode a H264 raw protocol from a camera but I'm having some problems using the Jcodec H264Decoder. I receive an array of integers with the information from the camera. Below a sample of the data: array: 00 00 01 FD 00 00 14 69 00 00 00 01 61 E4 80 6F D3 5B 76 97 DF 04 3A EF 54 97 0E D9 F5...more The code I'm using is : ByteBuffer bb = ByteBuffer.wrap( Utils.intArrayToByteArray(array, arraySize) ); bb.rewind(); // Create a buffer to hold the output picture which is big enough

问题 Using an H264Decoder I would like to obtain the decoded YUV420 data as a Java byte array. I have searched all over and I don't see any examples that fit. ByteBuffer buf = ByteBuffer.wrap(h264EncodedByteArray); H264Decoder decoder = new H264Decoder(); // assume that sps and pps are set on the decoder Picture out = Picture.create(320, 240, ColorSpace.YUV420); Picture real = decoder.decodeFrame(buf, out.getData()); The "h264EncodedByteArray" would be an array of h264 encoded bytes from a stream
