Hi!
I write custom encoder codec and want to use threads to speed up encoding
process. I know what ffmpeg have frame level threads and slices threads, but in
my case best option is to use frame level threads with FF_CODEC_ENCODE_CB()
function.
But I have couple of questions:
1) Then I add AV_CO

Thanks I will chek it out!
For now my filter use standart filter_frame() function callback. But how to

Hi.
Currently, there is no legitimate way to flush data buffered within the

Actually one could flush muxer buffers with av_write_frame, but docs forbid

If original packet is corrupted, then parsed packet is probably corrupted too.

IMO, the x2 speed boost is a positive result, depending on the GOP
size. Decoding a series of P frames is much faster than for the same
amount of I frames. I don't believe some
xt which simply calls
read(), write(), and lseek() on an `fd` is minimal, but even this must
be measured carefully to compare with the original `file:` protocol.
Sincerely,
Alex Cohn

problem occurs in slice quant estimation and slice encoding.
if slice quant >= MAX_STORED_Q we dont use pre-calculated quant matrices but
generate new:
qmat = ctx->custom_q;
qmat_chroma = ctx->custom_q;
for (i = 0; i < 64; i++) {
qmat[i] = ctx->quant_mat[i] * quant;
qmat
, after all we pass qmat/qmat_chroma to function where we
estimate encoded slice size or encode slice:
estimate_slice_plane / encode_slice_plane
I will make new patch with detailed description

The code is trivial but the semantics in the spec are ambiguous. This
should help keep parts of the muxer interpreting them consistently.

I like the idea -- it will be then possible to link to hardware
acceleration.
I don't think R-D optimization (including taking VLC / CABAC into account)
belongs to the library -- this, as well as figuring out partitions, should
be up to the actual encoder.

Aliased compressed AAC bytes are almost certainly not meaningful SBR
data. In the wild this causes harsh artifacts switching HE-AAC streams
that don't have SBR headers aligned with segment boundaries.
Turning off SBR falls back to a default set of upsampling parameters
that can function as a sort
