[FFmpeg-devel] [PATCH 1/4] fate: never generate auto-generated references

[FFmpeg-devel] [PATCH 1/4] fate: never generate auto-generated references

[Marton Balint]

GEN=1 is used to generate reference files in the source tree, not
auto-generated reference samples.

Without this patch GEN=1 could overwrite the auto generated reference files
in each test where they are used causing failures.

[FFmpeg-devel] [PATCH 2/4] swresample/resample: rework resample_one function to work the same way as the others

[Marton Balint]

This also fixes resampling with filter_size=1 and phase_shift=0, depending on
input chunk size noticable corrpution was hearable with this command line:

ffplay -f lavfi -i "sine=440:r=8000:samples_per_frame=32,aresample=24000:filter_size=1:phase_shift=0"

please correct me if iam wrong, but this looks like that
resample_one() is used in some case where it doesnt produce correct
results ?

And to fix this your patch replaces the resample_one() optimization by
unoptimized code

I think what should be done is first understand why it produces
wrong output and if thats some edge case that can be just handled
better by teh common code or a new function. Or if some of the code
related to resample_one() is buggy n which case that should be fixed.
or if instead theres a issue in teh common code and you reuse resample_one
there and remove its optimizations because of that new use case.
I cannot tell ...

thx

[FFmpeg-devel] [PATCH 1/2] swresample/resample: fix rounding errors with filter_size=1 and phase_shift=0

[Marton Balint]

Depending on input chunk size noticable corrpution was hearable, here is an
example command line:

ffplay -f lavfi -i "sine=440:r=8000:samples_per_frame=32,aresample=24000:filter_size=1:phase_shift=0"

Fix this by rounding the fixed point fractions up instead of down.

For the following command line

time ./ffprobe -f lavfi \
"sine=440:r=8000:d=86400:samples_per_frame=2048,aresample=24000:filter_size=1:phase_shift=0" \
-show_packets >/dev/null

Before the patch:

real	0m3,916s
user	0m3,812s
sys	0m0,104s

After the patch:

real    0m3,597s
user    0m3,457s
sys     0m0,140s

So it actually speed things up.

Regards,
Marton

Sure. The patch does not change the conditions when resample_one is used.

This computation is done repeatedly for each channel, thats not needed
its enough if its done once

I consider that negligable for real cases, and it makes the code cleaner 
doing the computations here.

If you insist on this, then it is better to rework all the resample funcs 
to work on all channels in a separate patch.

It would make asm optimized functions more difficult to implement too while
being less efficient.

That would be work as IIRC there are asm optimiezd versions
of these. Also iam not sure about the complexity overall decreasing with
such change

either way iam not "insisting" on anything, i just want the code to be
simple, clean and fast. I think the original code was close to achieving
this, it just was buggy.

Really iam happy about any ovarall improvment you want to do.
But this started out as a bugfix, and in that context seeing a non
bugfix change looks wrong to me

If you want to simplify or otherwise improve swr, iam not in your way
but please make sure the code really does improve and doesnt just
look better to you.
For example when its obvious a change would affect cases with small
blocks and many channels the worst, the speed of such case should be
tested. Not just a mono case

I just feel we draw the line between code simplicity and performance of 
rare or artificially constructed cases in different places.

I will drop this patch for now, I don't want to delay the set this was 
initially part of. (which by the way is an attempt to fix the ffmpeg.c 
audio frame performance issue caused by its threading changes)

Marton

[FFmpeg-devel] [PATCH 3/4] fate/libswresample: force number of samples for the input of aresample async tests

[Marton Balint]

Since PTS is changed randomly for every audio frame, it matters. Also add some
forgotten filter dependencies.

[FFmpeg-devel] [PATCH 4/4] avformat/wavdec: dynamically set max_size by default

[Marton Balint]

The wav demuxer by default tried to demux 4096-byte packets which caused
packets with very few number of samples for files with high channel count.
This caused a significant overhead especially since the latest ffmpeg.c
threading changes.

So let's use a similar approach for selecting audio frame size which is already
used in the PCM demuxer, which is to read 25 times per second but at most 1024
samples.

1024 samples seems to be quite small, in particular for files with few
channels (like stereo).

1024 is kind of a historical default. Also having multiples of 1024 is 
beneficial for some codecs which encode this many samples per frame.

In any case, I am not against somewhat increasing this, but it should be 
done for both PCM and WAV, it can be a separate patch and discussion.

Regards,
Marton

I will apply this set soon unless there are other comments. Will send a 
patch after that to increase the default sample amount for wav and pcm.
