(Thin)LTO llvm build
...k to building with -DLLVM_ENABLE_LTO=On and using the system CC/CXX (gcc 6.1). The resulting installed build is many times bigger than the non-LTO version. Is this to be expected? I thought LTO would reduce size by detecting more unused code. The bindist .tar.xz archives are as follows: LTO=Off: 195MB LTO=On : 953MB Now, I am of course aware that falling back to gcc's lto support is not the same as llvm's lto or thinlto, but I only fell back after it failed to build that way, and I wasn't aware of gcc6 providing almost 5x large code than without lto. Also, given a fresh 3.9 install...

Dropped frames streaming video to samba
...amba setup exporting an xfs filesystem. The box is an opteron 265 with 4G RAM and a QLogic QLA2312 HBA running SLES9. We can dd an 8G file to a share from a windows workstation in just over 2 minutes (about 65MB/s) and dd back in about 4 minutes. Local disk performance in the machine gives about 195MB/s to disk and 120MB/s from disk. The problem comes when trying to capture video using Adobe Premiere 6.5 and write straight to the share - we get a *lot* of dropped frames (somewhere in the region of 25%+). Yet the same job to an Adaptec Snap server (which is samba on adaptec's guardianOS) wor...

Webm files written without duration in header
Hi Marvin I followed this advice for updating moov flags in mp4 and it "streams" directly from the file location on the server with html5 video: https://rigor.com/blog/optimizing-mp4-video-for-fast-streaming. Progressive downloading, seeking and video time all works 100% on a 195MB file.

Huge OO.org packages installed by default
I was just wondering if anyone here knows why the OO.org packages on RHEL/Centos are so huge. Eg. On Mandriva 2006: 40834529 OpenOffice.org 113064600 OpenOffice.org-libs 20124669 OpenOffice.org-help-en 19976941 OpenOffice.org-l10n-en = ~185MB On Centos 4: 683298379 openoffice.org-i18n 124072694 openoffice.org 111894560 openoffice.org-libs = ~876MB!! When I say 'installed by default' I

disk space trouble on ec2 instance
...st. So I just solved this problem that you can only seem to do this easily on AWS. I grabbed the smallest EBS volumes that I could use (1GB for www and 2GB for /usr/local) respectively to use for those directories. 1GB being the smallest EBS volume you can get. So like I said earlier, I had around 195MB of data in /var/www and about 1.5GB of date in /usr/local. So I just mounted them on /mnt/www and /mnt/local and rsynced hte contents of those directories there. Blew away the contents of the original directories with rm -rf (scary but I was very careful while doing this). Then re-mounted them on t...

disk space trouble on ec2 instance
Hey all, Ok, so I've been having some trouble for a while with an EC2 instance running CentOS 5.11 with a disk volume reporting 100% usage. Root is on an EBS volume. So I've tried the whole 'du -sk | sort -nr | head -10' routine all around this volume getting rid of files. At first I was getting rid of about 50MB of files. Yet the volume remains at 100% capacity. Thinking

Webm files written without duration in header
Hi Fred. Appreciate your response. Maybe in my explanation I have some red and green apples, but I can agree that my understanding is as you explained it. 😊 The point is that if I can successfully stream mp4 with H.264 and AAC encoding without any issues to icecast, I can then use ffmpeg to turn it into HLS which then solves my iOS support issue. The CPU cost of repackaging MP4 into HLS
