#10453: Preset definition for slower seems to be missing -------------------------------------+------------------------------------- Reporter: monochromec | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: Keywords: preset | unspecified slower | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When trying to transcode a media stream to HEVC, the corresponding preset seems to be missing. How to reproduce: {{{ % ffmpeg -i input -vf scale=768:432 -c:v hevc -pre slower -c:a libmp3lame output ffmpeg 6 built on Debian bullseye }}} The invocation above works with ffmpeg version 4.3.6 (from the OS distro repos) although /usr/share/ffmpeg only contains the presets as found on Github in the corresponding "presets" directory. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10453> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10451(undetermined:new): Reduced luminance and banding artefacts converting DCP JPEG2000 to ProResHQ

#10451: Reduced luminance and banding artefacts converting DCP JPEG2000 to ProResHQ -------------------------------------+------------------------------------- Reporter: | Type: defect overlookmotel | Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- I am trying to convert the video MXF of a DCP (Digital Cinema Package) to ProResHQ. DCPs' MXFs are encoded as JPEG2000 in XYZ colour space, and my intent is to produce a ProResHQ file in Rec709 colour space. The conversion works, but the output is incorrect in 2 respects: 1. Luminance is reduced. 2. In tones close to black, red, blue and green depart from each other and banding artefacts appear in dark areas (dark green blocky splodges).

#10447: On macOS ffmpeg should create a power assertion to prevent system sleep while job runs --------------------------------+--------------------------------------- Reporter: porg | Type: enhancement Status: new | Priority: normal Component: ffmpeg | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | --------------------------------+--------------------------------------- == Problem - Started a long encoding job, CPU was at 540% on my 8 cores, fans on, encoding speed showed as circa 2.5x. - Left MacBookPro unattended in good spirit to come back to a finished result. - Came back some 30min later or so. Screen was dimmed: Expected. But: Fans silent... - Touched keyboard (to wake it from sleep or at least dimmed screen with the system running in a reduced power state, not sure which of the two it was) - ffmpeg encoding speed now showed at a crawling 0.05x or similar (accumulated average over time). - Conclusion: The system has been in sleep or reduced power state and the encoding had came to a halt or slowdown. == Reproduction - Start a long ffmpeg job - Check macOS power assertions with `pmset -g assertions` - There is no power assertion by ffmpeg which would prevent system sleep. == Competition & Best Practices [https://handbrake.fr HandBrake] on macOS automatically sets a user requested power assertion: {{{ $ pmset -g assertions [...] pid 1234(HandBrake): [0x0003118f00019293] 00:00:15 PreventUserIdleSystemSleep named: "HandBrake is currently scanning and/or encoding" [...] }}} == Proposed Solution - Offer "prevent-sleep" as an argument or config. - Ideally on macOS to be compliant with conventions this is ON as a default and needs to be opted out. - This should not re-invent the wheel but utilized the proper mechanism for this on the respective platform. (macOS in my case). == macOS I/O Kit power assertions - On macOS processes can create a power assertion to prevent system sleep until they are done and the assertion gets revoked. - This is great to start long jobs (like video encodings) unattended and be sure that this job runs uninterrupted and unthrottled until done. Then the system may go to sleep (according to your setup). - See manpage and its chapters/keywords - [https://ss64.com/osx/pmset.html pmset] -- manipulate power management settings - `-g assertions` - [https://ss64.com/osx/caffeinate.html caffeinate] -- prevent the system from sleeping on behalf of a utility - `-i` Create an assertion to prevent the system from idle sleeping. - caffeinate -i ffmpeg ... == Environment - ffmpeg 5.1.2 (installed via brew) - macOS 11.7.7 Big Sur == Workaround - Invoke `ffmpeg` yourself via `caffeinate -i ffmpeg ...`. - After 10 secs I checked pmset -g assertions and saw that it had created a corresponding assertion indeed: {{{ pid 12345(caffeinate): [0x0003105200019286] 00:00:10 PreventUserIdleSystemSleep named: "caffeinate command-line tool" Details: caffeinate asserting on behalf of 'ffmpeg' (pid 12345) Localized=THE CAFFEINATE TOOL IS PREVENTING SLEEP. }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/10447> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10446(undetermined:new): Support decoding with libsvtav1

#10446: Support decoding with libsvtav1 -------------------------------------+------------------------------------- Reporter: Jozef | Type: Chutka | enhancement Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: av1 | Blocked By: libsvtav1 | Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- I am surprised to learn that ffmpeg does not provide libsvtav1 decoder. I have ffmpeg compiled with SVT-AV1 support linked with `-lSvtAv1Dec -lSvtAv1Enc` however only encoder is available. Please add decoding support for svtav1 so one does not need configure build like svtav1 encoder + libaom decoder. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10446> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10445(avcodec:new): nvenc intra-refresh disabled

#10445: nvenc intra-refresh disabled ----------------------------------+-------------------------------------- Reporter: thorvald | Type: defect Status: new | Priority: normal Component: avcodec | Version: git-master Keywords: nvenc | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+-------------------------------------- On current master, nvenc intra-refresh seems to not work. I'm unfortunately not set up to bisect on this machine, but looking at the code in ```nvenc.c```, there was a change in 99dfdb45a89955916651eeaeac77d938e9a4217a for ```hevc->intraRefreshPeriod``` from ```avctx->gop_size``` to ```cc->gopLength``` However, there's _also_ code which sets gopLength to NVENC_INFINITE_GOPLENGTH if intra_refresh is set, so this combination seems to result in intraRefreshPeriod being effectively disabled. If I downgrade to a build from Jun 21st, intra-refresh works again. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10445> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
