By using avio_get_dyn_buf() + ffio_free_dyn_buf() instead of avio_close_dyn_buf() + av_free() one can avoid an allocation + copy for small dynamic buffers (i.e. small master elements). Signed-off-by:Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

Up until now, using a dynamic buffer entailed at least three allocations: One for the AVIOContext, one for the AVIOContext's opaque (which, among other things, contains the small write buffer), and one for the big buffer that is independently allocated that is returned when calling avio_close_dyn_buf(). It is possible to avoid the third allocation if one doesn't use a packetized dynamic buffer, if all the data written so far fit into the write buffer and if one does not require the actual (big) buffer to have an indefinite lifetime. This is done by making avio_get_dyn_buf() return a pointer to the data in the write buffer if nothing has been written to the main buffer yet. The dynamic buffer will then be freed using ffio_free_dynamic_buffer (which needed to be modified not to call avio_close_dyn_buf() internally). So a typical use-case like: size = avio_close_dyn_buf(dyn_pb, &buf); do something with buf av_free(buf); can be converted to: size = avio_get_dyn_buf(dyn_pb, &buf); do something with buf ffio_free_dynamic_buffer(&dyn_pb); In more complex scenarios this can simplify freeing as well, because it is now clear that freeing always has to be performed via ffio_free_dynamic_buffer(). Of course, in case this saves an allocation it also saves a memcpy. Signed-off-by: -

The G729 reference decoder clips after each individual operation and keeps track if overflow occurred (in the fixed point implementation), this here is simpler and faster but not 1:1 the same what the reference does. Non fuzzed samples which trigger any such overflow are welcome, so the need and impact of different clipping solutions can be evaluated.

As is the decoder will never stop, it will cause an infinite loop. The RFC seems only to speak of non empty packets so endlessly generating noise from the last empty flush packets seems wrong.
