The function to write an ordinary (luma or chroma) plane as well as
the function for writing an alpha plane have some similarities:
They record the initial bitposition (despite said position always being
byte-aligned), flush the PutBitContext themselves and return the amount
of bytes they wrote.
Despite write_huff_codes() receiving an ordinary buffer (not a
PutBitContext), it returned the amount of data written in bits,
not in bytes. This has been changed: There is now no intermediate
bitcount any more.

Several encoders used code like the following to check for the amount of
bytes left in a PutBitContext:
pb->buf_end - pb->buf - (put_bits_count(pb) >> 3)
Besides the fact that using the pointers directly might pose
a maintainence burden in the future this also leads to suboptimal code:
The above
A PutBitContext has a field called size_in_bits which is set to the
context's bitsize init_put_bits(); but it isn't used at all (the PutBits
API uses pointers directly and not bit indexes), so remove it (due to
ABI concerns the actual element is only removed at the next bump).
Furthermore, the
Often a caller doesn't want the amount of bits written via a
PutBitContext, but the amount of bytes. This in particular happens
after one has flushed the PutBitContext (e.g. at the end of encoding,
when one wants to know the actual packet size). The current way of doing
this is with

The PutBits API checks the available space before every write,
so this check for overread is dead.

We are already word-aligned here, so one can just as well flush the main

Compilation would fail if it were outcommented as it refers to a

Hi everyone,
Kieran, thank you for your reply.
I already had a look at that document.
I need something more detailed about FFmpeg's threading architecture such as:
1. What threading model is used in FFmpeg (e.g., thread pool, pipeline, or
peer)?2. Have someone explored the performance of the
In effect the patch does replace that one line. But it also adds the steps
to illustrate how the wallclock is calculated. Adding all the calculations
in a single line will make it too long and hard to read.
Note that delta_timestamp can be negative. It typically happens after rtcp
SR is received
