Hi, I'm a highschool student, I'm looking for information about converting Wave file (*.wav) into Ogg file (*.ogg) and i found encoder_example.c inside libvorbis's example directory. I try to compile it using Microsoft Visual C++ 6.0 ,but it goes error like this : --------------------Configuration: encoder_example - Win32 Debug-------------------- Linking... encoder_example.obj : error LNK2001: unresolved external symbol _vorbis_info...

Hi Developers, I have a 16-bit PCM data buffer, I want to write that to ogg file. Could you help me to understand how to write pcm data to the ogg? Thanks in advance.

...say that. The picture is just a bunch of coloured pixels. During the encoding process the video stream is defined like that: File stream.yuv is 320x240 15.00 fps 420 video. Why 420 ? Why not YUV like for the main theora trunk ? Another problem: I just updated theora and the last modification on encoder_example fails: encoder_example.c: In function 'main': encoder_example.c:806: error: expected expression before '<<' token encoder_example.c:810: error: expected expression before '==' token encoder_example.c:814: error: expected expression before '>>' token mak...

As was briefly discussed on IRC, ffmpeg and mplayer currently output two somewhat incompatible YUV4MPEG streams. This meant that encoder_example could take input from mplayer, but not ffmpeg or movtoy4m (a QuickTime->Y4M tool). This is a patch that fixes this issue and should allow encoder_example to take input from either format: diff -urd xiph-cvs/theora/examples/encoder_example.c xiph-cvs-new/ theora/examples/encoder_example.c -...

I have encoded successfully a YUV stream by using the encoder_example. Can We encode a row stream (get from a web cam) by using encoder_example. If we can not, is there any other way to encode a row stream by using theora codec. -- Nuwan Millawitiya -------------- next part -------------- An HTML attachment was scrubbed...

Hi all I have the raw out put of a video camera in following format: mjpegb, yuvj422p, 1920x1080, 24.00 fps(r). I cannot directly convert this raw footage to Theora due to the YUV4MPEG2 only restriction of the encoder_example. Isn't it better to support other raw formats in encoder_example, such as what I have, mjpegb, yuvj422p? I presume even if I convert the mjpegb, yuvj422p to YUV4MPEG2, I cannot convert it losslessly.

i have configuered and built libtheora with --enable-encoder but when i make install, encoder_example is not installed. why not? the object file and script are created in the examples subdir, they are just not installed... thanks for your help -------------- next part -------------- An HTML attachment was scrubbed...

hi all, i tried to encode a .yuv file with the encoder_example.c but it give an error message as follows ./encoder_example -v 1 file_1.yuv > file_1.ogg Input file file_1.yuv is neither a WAV nor YUV4MPEG2 file. so the error message is understandable for anyone. when this file is play with mplayer it shows as follow ===============================...

hello, i have vorbis sdk 1.0rc2 and i have could compile encoder_example.c in a console aplication project on VC 6. But when i execute the program, only appears the black visual display screen without obtaining result. where is my problems?? other question: in sdk there is for example, vorbis.dll and vorbis_d.dll, which is the difference? i have could compile any p...

Hi, Why do I get an error message when i'm running the "encoder_example.c" which is included in the SDK? The error occurs then the 44 bits are read and the vorbis_info struct is initiated (i.e. when the vorbis_encode_init(&vi,2,44100, -1, 128000, -1) - funcion is called. I also tried to read the data from a 16 bits 44,1 KHz stereo PCM - wave file but recived...

Hello, I recently attempted to build theora 1.1.1 with mingw-w64-gcc 7.1 and msys and it fails to build the encoder_example.c example program. There are multiple declarations of the function 'rint'. The source file created its own version of the function that rounds AWAY from zero. MinGW-W64 has its own version of the 'rint' function, which does not round away from zero. Therefore, encoder_example.c...

My first guess about the problem would be that the programs want to process the stuff in a different order, e.g. mplayer wants to output some sound before anymore video and encoder_example wants to receive some video before anymore sound. This could easily depend on the order of stuff in the file mplayer is reading. I guess something similar could happen for opening the pipes as well. The easiest solution I can think of would be to run 2 mplayer processes, one for video and one...

...y4m file. The resolution is 1280x720: 1. Xvid 17MB 2. Ogg/Theora Q7 31MB 3. Ogg/Theora Q8 38MB 4. Ogg/Theora Q9 49MB 5. Ogg/Theora Q10 61MB The Xvid file was made using mencoder by 2 passes with following options: bitrate=2500:autoaspect:chroma_opt:vhq=4:bvhq=1:quant_type=mpeg:pass=1 The encoder_example was used to create Ogg/Theora files. It was noted y4m to Theora encoding was the fastest that I have ever seen. The Q9 Ogg/Theora took only 2 minutes 35 seconds. But the files created were way too large compared to Xvid. The Xvid quality was very good, it may be equivalent to Ogg/Theora Q9 or Q1...

where do i can get these files -libogg.lib, -libvorbis.lib, -libvorbisenc.lib should i compile it on my own ? How do i compile it ? In step by step explanation please.. Thank you..

Hello, Some years back I tried to use example_encoder.c with mkfifo FIFO buffers to encode content as it was being decoded by mplayer. This deadlocks, because to do this you need two FIFOs (one for decompressed audio and one for video) that mplayer alternates writing output to, and that encoder_example similarly alternates reading chunks of audio and video input from. The trouble is, mplayer will fill one of the two buffers (say the video FIFO) and still have more to write to that buffer before alternating back to the other one (audio), but encoder_example will remain in the "reading fr...
