Can I reduce the bitrate of an OGG file without recompressing everything? It would be useful to convert high bitrate ogg to lower bitrate ogg for portable players.

Is there a mechanism by which you can perform a zfs send | zfs receive and not have the data uncompressed and recompressed at the other end? I have a gzip-9 compressed filesystem that I want to backup to a remote system and would prefer not to have to recompress everything again at such great computation expense. If this doesn''t exist, how would one go about creating an RFE for it? cheers, James

yes I know I can do that, but my question is if there is software to edit FLAC files without having to uncompress to WAV/recompress to FLAC. 2007/7/23, Avuton Olrich <avuton@gmail.com>: > > On 7/23/07, Harry Sack <tranzedude@gmail.com> wrote: > > hi > > > > does somebody know software for editing FLAC files?

I just setup a new SSD with my laptop root filesystem, and at the time I though, "eh, I''ll just use zlib compression during the first copy, and then switch to lzo afterwards to maintain write speed when I''m using the laptop after the copy and reboot". Now, I rebooted with the new ssd and zlib compressed rootfs, and it seemed to boot slower than it did before with the

...e for each frame two variables stored in bitstream that will hold information about starting and ending position of \"valid\" samples in the frame. With these additional information it will be possible to do simple editing (like cutting or concatenating two streams) without decompressing/recompressing at sample-granularity. Simple example (size of frame==10 samples): | frame1 | frame2 | frame3 | frame4 | | | | 0000000000111111111122222222223333333333 : sample count 0123456789012345678901234567890123456789 : sample count | | | | A 0,9 B...

Git version of the FLAC encoder prints error message: ERROR: Compression failed (ratio 1.xyz, should be < 1.0). Please contact the developers. in the following cases: a) recompressing from FLAC 1.2.1 (sometimes) b) encoding very short wav files (around 5k samples) c) encoding white noise test signal.

hi does somebody know software for editing FLAC files? So I just want to cut some pieces out of the file (for example silence in front of a recording) thx -------------- next part -------------- An HTML attachment was scrubbed...

If I use flac with piped input it warns: FAILURE: Compression failed (ratio 495232,432, should be < 1.0). This happens for some files for one or more of the following reasons: * Recompressing an existing FLAC from a higher to a lower compression setting. * Insufficient input data (eg, very short files, < 10000 frames). * The audio data is not compressable (eg a full range white noise signal). Reproducible with the following command line: flac --ignore-chunk-sizes - -o out...

...unately, the original source code is unavailable, so I cannot rebuild the package as R 3.0.0 requires. Is there a straight forward way of converting the package (.rdb, .rdx and .rds files) in the binary package from a 2.14.1 version to a 3.0.0 version without the source code (perhaps uncompressing/recompressing somehow)? Naturally, since the R code is visible, I know I can output all of the parsed objects in the package to a text file to make a skeleton package that can then be built/installed. Something like this: objs <- ls(envir=loadNamespace("binaryPkg"), all.names=TRUE)...

...has a fair share of jazz in it. The worst-case track in this set has a ratio of 0.9442, due to some heavy use of distortion. Compiling this statistics, I noticed that on two of the tracks, there was a problem with the MD5 and min/max framesize being all zeroes, and the seek-table being corrupt. Recompressing caused the symptom to disappear. I have seen a similar behaviour earlier when recompressing some tracks using flac 0.10, but those symptoms disappeared after recompression with 1.0. Your TOC-hash algorithm would be interesting to examine, as I'm also intending to move the metadata into a d...

...content comparisons on the uncompressed copy of both archives, might this not result in less network traffic (sending only the small changes) than just looking at the compressed copies? (Yes, I realize that there are the additional (non-network) expenses of decompressing at both ends, and probably recompressing at the destination.) My particular application is OS installation tarballs, but a number of bloated or huge software products out there have sourceballs where there might also be real savings.

...s box to a Apache/ mongrel cluster. In lighttpd, mod_compress had a very nice feature: if there''s a static file, it would compress it in a user-specified compress folder. If the file hasn''t changed, it would just serve out the compress file; if the file has changed, it would recompress it and serve it out. Is there such a deployment option in Apache? Also, I read in the "best practices" Apache/mongrel doc <http:// mongrel.rubyforge.org/docs/apache.html> of the use of mod_memcache and mod_cache. But I don''t see it configuration scripts associated...

...is claimed that zstd offers improved compression over gzip, but (unlike lzma) it has comparable decompression speed. Maybe it is interesting to get an estimate of how much R packages would benefit from zstd. Testing this for source packages and MacOS binary packages it is easy as we can gunzip and recompress tar.gz files without having to extract the tarball itself: OUTPUT="sizes.txt" echo "FILE GZIP ZSTD" > $OUTPUT for x in *gz; do FILE=$(basename $x) GZIP=$(wc -c "$x" | awk '{print $1}') ZSTD=$(gunzip -c $x | zstd -19 | wc -c) echo &quot...
