I am using the master branch for stream transcoding, reading from memory and
sending the transcoded packets to the memory. To accomplish that, I use two
AVIOContext variables to feed into input and output AVFormatContext.
I ran into a memory leak after I free all the things I allocated. I traced
further, and noticed this in the aviobuf.c.
Note the avio_alloc_context actually allocates the superceding struct
FFIOContext, and only returns an element (&s->pub) from FFIOContext.
The question naturally is how am I going to free FFIOContext, not just
AVIOConect to plug the memory leak here?
AVIOContext *avio_alloc_context(
unsigned char *buffer,
int buffer_size,
int write_flag,
void *opaque,
int (*read_packet)(void *opaque, uint8_t *buf, int buf_size),
int (*write_packet)(void *opaque, uint8_t *buf, int buf_size),
int64_t (*seek)(void *opaque, int64_t offset, int whence))
{
FFIOContext *s = av_malloc(sizeof(*s));
if (!s)
return NULL;
ffio_init_context(s, buffer, buffer_size, write_flag, opaque,
read_packet, write_packet, seek);
return &s->pub;
}
Thanks,
Zed Zhang
