Grep for a number between a certain range - Checking WAV Quality
11 août 2014, par BT643I’m trying to write a regular expression (to be used in conjunction with ffmpeg, which can check that a WAV file is over a certain quality.
The minimum should be :
Audio Channels : 2 (Stereo)
Audio Sample Rate : 44,100 Hz
Audio Bitrate : 1411 Kbps
Audio Bit Depth : 16 bitSo I’ve tried the following commands so far :
/usr/local/bin/ffmpeg -i "/path/to/file.wav" 2>&1 | egrep 'stereo|2 channels'
This works fine to get a stero (2 channel) WAV. I’m getting issues with the next part, searching between a range of numbers.
/usr/local/bin/ffmpeg -i "/path/to/file.wav" 2>&1 | egrep 'stereo|2 channels' | egrep '[41000-196000] Hz'
Obviously this just searches each number individually, so it’s finding results if there’s a 4 OR 1 OR 0 OR 0 OR 0 etc...
The bit rate and bit depth just needs to be OVER 1411 and 16 respectively.
Thanks

Here’s the ffmpeg output for a low quality WAV which should be rejected :ffmpeg version git-2012-05-22-27127eb Copyright (c) 2000-2012 the FFmpeg developers

fate/filter-video : Avoid duplication for fate-filter-stereo3d tests
16 mai 2022, par Andreas Rheinhardtfate/filter-video : Avoid duplication for fate-filter-stereo3d tests
Also fix the requirements of these tests : Only the anaglyph
tests need a scale filter, yet it has been inserted for all tests
without any check for its presence.Signed-off-by : Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

Revision dac589d6d4 : Optimize bilateral filter to improve speed Optimization of bilateral filter : 1)
29 juin 2015, par Shunyao LiChanged Paths :
Modify /vp9/common/vp9_loopfilter.c
Modify /vp9/common/vp9_loopfilter.h
Optimize bilateral filter to improve speedOptimization of bilateral filter :
1) Pre-calculate the bilateral filters at all the
levels at the initialization.
2) Convert 1D matrix to 2D matrix, avoid too many
multiplications in the bilateral filter loop.
3) Fix a bug in "loop_bilateral_filter_highbd".
The right-shifted range index can be larger than 255.Change-Id : I42f6177e896706948e2403bd9edce46e3eb5cbf8
