similar to: libtheora test suite

Hi all. I'm Mat & I'm new :) I'm testing libtheora + libogg perhaps for a commercial product. I started watching encoder_example.c ... I simplified it for testing it easier. It seems ok to me but I have no experience with theora so I would like to know if my code is correct. I tried to debug it with Valgrind and I found 4 possible memory leaks... but I think they can be

Hello, I'm new to this list, and pretty much also to the codec universe. In a computer game I'm working on, there is an 3D TV-screen onto which I project the frames of a movie. The movie is of course stored as theora, no audio as it's not needed yet. I have it working so far, extracting a frame and uploading it to the graphics card when the scene is drawn. The example file

Enabling the following function in tests/noop.c: noop_test_decode () { theora_info ti; theora_state th; theora_info_init (&ti); theora_decode_init (&th, &ti); theora_clear (&th); theora_info_clear (&ti); } segfaults. The cause is that theora_decode_init() expects a theora_info structure which was previously initialized by passing actual bitstream data through

Hi all. I post a small app I made that create 2 clips using a V4L device. I would like to get every tips you think it's useful... Some notes: - I make 2 clips because in our project we create series of clips and it's important to check that the all the resources ( memory, descriptors, etc. ) are freed correctly and to reuse all the resources that can be reused - the clips are not well

Hi everybody, me again. I'm trying to write my own VFW-like dll... It doesn't need to do much. 1.) compress a single frame and give it back to the host application 2.) host applications sends the frame 3.) client application receives frame 4.) client application tells the dll to decompress the data So if I try to do this, something is going wrong... Perhaps someone could have a look at my

Everyone, I've made a new release of our libtheora reference implementation. This draws a line under all the development since alpha 4 before we start merging in the optimization work people have been doing. It also contains a fix for two serious bugs (one an encoding error, one a segfault) so we recommend everyone upgrade. The release is source and binary compatible with 1.0 alpha 4.

Hello. How can I tell the number of frames in ogg/theora video file, without actually reading the file? Or, how can I tell its playing time (which is basically the same thing). I didn't find the information in THEORA_STATE, THEORA_INFO, but with the codec installed (illuminable oggcodecs), Windows Media Player shows the ogg/theora file playing time, before it starts playing the file.

Hi, I'd like to add user-allocated frame memory to theora via a theora_user_yuv_out callback. An additional helper function (theora_user_buffer_is_freeable) would also be required. With these two functions, user applications could submit memory buffers directly to libtheora, which would reduce the number of frame copies in a typical application from two per frame to one per frame. I've

Hi I've just started development on a streaming TV player using Theora as a real time encoder. The player currently uses the majority of code in src/player_example.c. I discovered a bug which was preventing the player from working correctly, but which only showed up in my player; it didn't seem to affect the original player_example. I've now found the cause, which is indeed a

The theora_unpack_comment casts a pointer-to-int to pointer-to-long. This is incorrect on AMD64, where ints and longs are of different size. On my system (Debian unstable, gcc 4.1) this causes players to crash when they reach the end of a movie. The patch below fixes this bug. --- libtheora-0.0.0.alpha7/lib/toplevel.c 2006-06-13 00:57:36.000000000 +0200 +++ libtheora-pdw/lib/toplevel.c

I found a bug in theora_decode_init when I was implementing the decoder. theora_decode_init should be zeroing the theora state structure right? memset(th, 0, sizeof(theora_state)); // Erik -------------- next part -------------- An HTML attachment was scrubbed...

Hello, I'm not sure if this list is the proper place for this post; please correct me if it is not. I am attempting to use libtheora and I have been looking through the examples in the distribution Excerpt from encoder_example.c -- case 'V': video_r=rint(atof(optarg)*1000); if(video_r<45000 || video_r>2000000) { fprintf(stderr,"Illegal

Hi, I am creating a new ogg stream for theatrical/stage/disco lighting and am having trouble encoding my comment header with the following code in _tp_writelsbint function, it does not write the second byte to the ogg buffer. I am using windows and have created a new win32 library project with visual studio and added my code, what do i have to do to get the function working? Is there a project

Hi people, I'm writing a decoder that uses libtheora on Windows and Linux. Decoding works well by now. I have a couple of problems with it, that I just can't seem to figure out. I'll write each of them in a single mail, so it's easier to answer individual problems. The first problem I have is seeking, when it's playing files. I have implemented a weighted binary jump

Well, as you may have seen from my previous messages, I'm doing a webcam stream program. The encoder is working well right now, but I'm having some hard time with the decoder. I know the parameters used in the encoder, and they are not gonna change, so I want to init the encoder directly into the client. The problem is that if I give the values to theora_info and after that I call

Hi, Ralph recently checked in a version of theora/tests/noop.c that uses the new API. Part of the reason for this test is to check for memory leaks in the library's constructors and destructors. You can run the test suite under valgrind by configuring with --enable-valgrind-testing. The test passes, but gives output like: make[1]: Entering directory

Hello everybody, while developing an application for the company I work for, I noticed that very often libtheora reports division by zero errors. I fixed those errors by adding a few additional checks, but I'm not 100% sure that these checks are correct. Could you please check out the attached patch file and tell me what you think?
