Dear Vorbis devs, I'm Robert Kausch, author of fre:ac - free audio converter. Please consider using _ogg_malloc/_ogg_free in place of alloca in vorbis_comment_add_tag. alloca will cause undefined behaviour/crashing when it causes a stack overflow which can easily happen when adding cover art in a METADATA_BLOCK_PICTURE comment. I had a user trying to convert a FLAC file with a 2 MB embedded cover art th...

Hi, As far as I see in libvorbis most of the places where _ogg_malloc(), _ogg_realloc and _ogg_calloc() is called the return value is not checked for out of memory condition. Is there any plan to change this? For my use-case the application is not allowed to crash. So if libvorbis can not handle this condition, I guess I would need to preallocate a large enough cust...

Hi all. I'm here again :) The small leak in my app is gone. I'm going on with it, now I grab a frame from a video device and I encode it with Theora... The debugger ( valgrind ) says: ... ==2782== Invalid read of size 1 ==2782== at 0x1B94B0BD: PixelLineSearch (scan.c:1482) ==2782== by 0x1B94B35A: PixelLineSearch (scan.c:1597) ==2782== by 0x1B94B447: LineSearchScorePixel

Hello! First of all a question: When you make the encoder tables (ie: mode_e.h) do you use the mapping0_forward function? Because you made the encoder tables, and after this you did a minor correction in the final beta4 ... (this correction was: additional[0]=fabs(additional[0]*scale); in the mapping0_forward function) (I see this was a bug, and the modification was correct, but this correction

I am writing an Ogg Vorbis decoder for win32. I want a memory buffer which is aligned to the disk sector size (512 bytes on hard disk, 2048 bytes on cd/dvd), so that the win32 function ReadFile can be persuaded to do 'unbuffered IO'. Unfortunately, the ogg_sync_buffer() call gives me a pointer from its own, internally allocated buffer. I have found no docs to indicate that this would

...; you immediately get a segmentation fault which really is undesirable. However, I could be totally wrong as I might have overlooked something. My suggestion is this: Just do a malloc() on the condition that b is NULL: void oggpack_readinit(oggpack_buffer *b,ogg_reference *r){ if (!b) b = _ogg_malloc(sizeof(oggpack_buffer)); memset(b,0,sizeof(*b)); b->tail=b->head=r; b->count=0; b->headptr=b->head->buffer->data+b->head->begin; b->headend=b->head->length; _span(b); } That way you have to initialize your b before calling the function though (like...

Hello, I am programmer working on a product which integrates Theora. I have a question regarding the memory use on some of the internals of Theora. Is this the right forum for this question, and if not, does anyone know where an appropriate place to ask is? Thanks Sam -------------- next part -------------- An HTML attachment was scrubbed... URL:
