The format you're describing here actually has *more* overhead than Ogg, not less. It's also unseakable, not robust errors, and without support for metadata. I'm not sure why you would want that. It's not like you're forced to include much data in the Ogg metadata (which seems to be the source of all the overhead you're seeing). Jean-Marc On 05/12/2016 11:51 AM, Amit

Hello Jean-Marc, As an example, I am using the output of opus encoder to store the file as the following format and read back the same during decode process, without having much overhead.

Hello Jean-Marc, Assuming that a 48KHz, 20ms 8-bit linear PCM data which is 960 bytes is compressed to 64 bytes (for assumption). The with the Oggs header (4 byte) + 1 segment entry (which is the size of the segment itself) + 64 bytes will amount to (4+1)/(4+1+64) = ~7.2%. This when compared with the original Oggs container itself for the same data payload size (26+1)/(26+1+64) = ~29.6%. Even if

Hi Ulrich, As Jean-mark recommended, we created "--enable-check-asm" config option to active OPUS_CHECK_ASM macros in the optimization, where the C function is called inside and the results of C and optimization functions are compared when encoding/decoding the real audio files.

The overhead of Ogg (in file size) is pretty small and it's efficient enough for most applications (and uses far less CPU than the codec anyway). If anything, you might want to look at optimizing the existing Ogg implementation (e.g. like Tremor did in the context of Vorbis). Of course, you're always free to design a new container, but I doubt it's worth it and it's a lot of work

Hi, I installed Fedora 10 as domU on CentOS 5.3. I need new 2.6.25.14 kernel under domU (in order to patch it for MPLS protocol). I followed advice on http://wiki.xensource.com/xenwiki/Kernel.org_Linux_on_Xen, and compiled kernel with XEN options enabled under domU. I got all relevant packages in /boot and /lib/modules, but when I try to boot virtual machine I got this error: Error starting

Hello Jean-Marc, I suspected the answer to be No. For HMI panels, except for the capture pattern and a single page segment entry, other fields are not important, and which results in almost 7% overhead for a 20ms raw frame encoded with Opus. At the same time the file processing complexity is way too less considering that CRC's do not not need to be considered (programmer pods ensure that)

Hi! I was just trying libopus0-1.1-3.2.x86_64 and opus-tools-0.1.9-3.2.x86_64 on openSUSE Leap, and I was wondering: opusenc does not display the file name it processes. In Lunux when you use some batch processing, it might be interesting! Example output for "for f in *.wav;do opusenc --bitrate 160 $f ${f%.wav}.opus; done": ---just on file--- Encoding using libopus 1.1 (audio)

Hello Ulrich 20ms is the size of each frame. The overall sound clips may be 0.25 - 0.75 secs each.

"Unfortunately my search for a good free player for Android was not very successful" - I presume you are using an Android device. If that's the case, portable devices have really bad electronics from the point of view of HiFi - because of low voltage and output amplitude being close to power rails. My point is that you are not really comparing one lossy format to another, but rather

Hi! You probably know already, but recently there's "fobbar2000 mobile" available for Android (I think Windows and iOS, too), and it plays Opus even ol older Android (like 4.0). Ulrich

Hi, this is a bit off-topic, but maybe you can help me: When extracting the autio track of a concert on video DVD, I noticed that the *.VOB files each contained only about 16 minutes of music, resulting in multiple files.

Hello Ulrich, Putting some extra space is the not the reason for this request. It is the overhead of the frame v/s payload size. Basically larger the payload less % the overhead is (and that makes sense). However the complexity of implementing a read file structure where the file pointer has to go back-forth for reading the payload when multiple segments have to be read, CRC32 (something which
