Where are Cingg's ffmpeg compression files located?
by Terje J. Hanssen 08 Nov '24

08 Nov '24

During render testing to and fro, I have had a suspect that now and then the content of ffmpeg compression type has changed or could not be picked up again. But I have thought it was me that had confused or forgot something. Or may this occur by other reasons? Seemingly this happened recently during render switching between hevc_vaapi,mp4 and hevc_qsv.mp4 . hevc_qsv.mp4 has several more pixel options than hevc_vaapi.mp4 which has only the single "vaapi" option. And in one occasion I got more pixel options for hevc_vaapi.mp4(?) - or was it still on hevc_qsv,mp4? So to find out, I have tried to edit the hevc_vaapi.mp4 file, but have not got the edited content loaded in the video wrench compression window. So I wonder where is the preset file used by Cingg located? I have # ls -l /Cin lrwxrwxrwx 1 root root 29 Oct 22 20:23 /Cin -> /home/cinelerra/cinelerra-5.1 and the hevc_vaapi.mp4 preset file with the same content located in both /Cin/bin/ffmpeg/video /Cin/ffmpeg/video But the edited content isn't visible in Cingg?

Enable Cingg single-user build to use system libSvtAv1Enc upgraded to v. 2.3.0

But when I tried now to render the same hdv file as with ffmpeg, Cingg failed with int FFMPEG::open_encoder(const char*, const char*): cant find codec libsvtav1:/Videoklipp/AV1/hdv09_04_m2t_svt-av1_230.webm Shouldn't Cingg be able to work with the system upgraded libSvtAv1Enc2 v. 2-3-0 automatically as well as ffmpeg does? Or if necessary via a simple "update", without complete rebuild? ------------- I had a look at my last rebuild of Cingg for using ffmpeg 7.1 : Does "disabled libsvtav1" say something? # ./configure --with-single-user --disable-static-build --without-thirdparty --without-libdpx configure: loading site script /usr/share/site/x86_64-pc-linux-gnu ..........snip checking for /usr/local/cuda/include/cuda.h... no checking cuda sdk... no checking for dlopen in -ldl... yes checking for numa_alloc in -lnuma... yes checking for openexr available... yes Reason Package ------ ------- disabled encore disabled audiofile disabled esound disabled libsvtav1 ...snip...

New SVT-AV1 release: v2.3.0 from AOM
by Terje J. Hanssen 05 Nov '24

05 Nov '24

As seen on reddit, the Alliance for Open Media - AOM has released SVT-AV1 v. 2.3.0 The Scalable Video Technology for AV1 (SVT-AV1 Encoder) is an AV1-compliant software encoder library. * NEW FAST DECODE MODE * New fast-decode (2) to allow for an average AV1 software cycle reduction of 25-50% vs fast-decode 0 with a 1-3% BD-Rate loss across the presets * Improved fast-decode (1) option to increase its AV1 software cycle reduction by ~10% while maintaining the same quality levels * Improved --lp settings for high resolutions, with CRF gaining a ~4% improvement in speed and VBR gaining ~15% * Further Arm-based optimizations improving the efficiency of previously written Arm-neon implementations by an average of 30% * Address speed regressions for high resolutions first pass encode by tuning the threading parameters, with 1080p showing the biggest gains * Enabled AVX512 by default in cmake allowing for ~2-4% speedup * ...and more https://gitlab.com/AOMediaCodec/SVT-AV1/-/releases/v2.3.0#230---2024-10-28 https://gitlab.com/AOMediaCodec/SVT-AV1/-/blob/master/README.md?ref_type=he…

VAAPI supported Encoding formats
by Terje J. Hanssen 03 Nov '24

03 Nov '24

In hope it may be of some use for Cingg next, I make a summary and supplement to the guide in https://trac.ffmpeg.org/wiki/Hardware/VAAPI#Encoding And instead of adding a tail to already too long recent threads, I start a new thread here. Two additional references are used Developer Reference: Media Capabilities Supported by Intel Hardware https://www.intel.com/content/www/us/en/docs/onevpl/developer-reference-med… Supported Encoding Input Format and Max Resolution https://github.com/intel/media-driver/blob/master/docs/media_features.md#su… to clarify the Encode Features for my own Intel Arc A-series Discrete Graphics HEVC (fixed-function hardware + shader-based) 8-bit, 4:2:0 (NV12) 10-bit, 4:2:0 (P010) 8-bit, 4:2:2 (YUY2, Windows only) 10-bit, 4:2:2 (Y210) AV1 8-bit, 4:2:0 (NV12) 10-bit, 4:2:0 (P010) A short reminder: 8-bit vs 10-bit color depths is 256 vs 1024 color levels of each RGB color, or 16.7 mill. vs 1.0 bill colors. 4:2:0 vs 4:2:2 color sub-sampling is keeping 1/4 vs 1/2 of all 4:4:4 colors or the precision of color compression. https://fujifilm-x.com/en-us/series/the-filmmakers-handbook/8-bit-or-10-bit… An important point to notice is that the VAAPI encoding 'formats' are based on those in the parentheses () above. Three simplified ffmpeg code lines with default bit-rates and without audio are used in the following three examples. Resulting fps encoding counts or speeds are the same in all cases; I don't know why.
