#3433(ffmpeg:new): using "shortest" results in mismatched audio and video lengths

#3433: using "shortest" results in mismatched audio and video lengths -----------------------------------+-------------------------------------- Reporter: mjmvisser | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: git-master Keywords: shortest | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+-------------------------------------- Summary of the bug: "-shortest" does not add trim/atrim filters, so the length of each output stream will be a multiple of sample size. In the given example, the video is exactly 1s, but the resulting output is 1.02s. If "-t 1.000" is passed instead of "-shortest", the resulting output is exactly 1s. The difference is that using "-t" adds trim/atrim filters, so the last frame->nb_samples encoded will be truncated to fit the given duration. How to reproduce: {{{ % ffmpeg -y -probesize 500000 -f image2 -r 25 -i colorbars.%04d.png -i 100Hz_44100Hz_16bit_05sec.wav -shortest -c:v png -c:a pcm_s16le -q:v 1 -2 -f mov colorbars.mov Note that input streams have durations of 5s and 1s. % ffprobe colorbars.mov Note that the output stream has a duration of 1.02s. ffmpeg version N-60960-gf3eef02 built on Feb 28 2014 10:31:20 }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/3433> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10604(undetermined:new): NVENC: Video Codec Changes to Older Preset and RC Mode Support

#10604: NVENC: Video Codec Changes to Older Preset and RC Mode Support -------------------------------------+------------------------------------- Reporter: hydra3333 | Type: | enhancement Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: nvenc nvdec | Blocked By: nvidia sdk | Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Hello. Looks like older presets are being removed, which could mean changes may be needed to ffmpeg. Hello, I received an email with this info: Planned rollout in 2024. What to Know About This Update The NVIDIA Video Codec SDK is working towards updates regarding preset support. In this update support for older presets will be removed. Background: • Video Codec SDK introduced new presets (p1-p7) and RC modes for H264 and HEVC in Video Codec SDK 10.0 in June 2020. This was done to simplify the usage of NVENC presets. • Older presets and RC modes are currently supported in four SDK versions (10.0, 11.0, 11.1, 12.0). • The older presets and RC modes support only HEVC and H.264. AV1 or new features such as split encode, encode quality improvements done post v10.0 are not supported. • In SDK 12.1, the older presets and RC modes were removed from the Video SDK C header. • Video Codec SDK supports backward compatibility. Applications compiled with SDK versions < 10.0 using older presets and older RC modes are supported in the driver. Future steps: • The plan is to remove driver support in R550 (Q1’24). Therefore, all applications compiled with older presets/RC modes will stop working if upgraded to R550 drivers. • The R545 will be the last driver release which will support the older presets and RC modes. The R545 release notes will have the final warning included. Migration guide: • NVIDIA has provided a migration guide (NVENC Preset Migration Guide - NVIDIA Docs) to enable a seamless transition to the new NVENC API preset architecture. • Please refer to the link below for details regarding HEVC, H.264 migration tables. Learn More https://docs.nvidia.com/video-technologies/video-codec-sdk/12.1 /nvenc-preset-migration-guide/index.html (has a list of preset mappings) -- Ticket URL: <https://trac.ffmpeg.org/ticket/10604> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

The checksum should be different as the decoded file differs by having 20 more samples at the end. The rest of the file seems unaffected. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10540> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10217(undetermined:new): mlp enc: broken output when input is 8-bit 44kHz

#10217: mlp enc: broken output when input is 8-bit 44kHz -------------------------------------+------------------------------------- Reporter: ami_stuff | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- FFmpeg's mlp/truehd encoder produces broken files when the input is 8-bit and has exactly 44100Hz. When the input is for example 8-bit 44099Hz, this problem doesn't happen. The encoder is still in experimental state, but this issue shouldn't be missed. {{{ ./ffmpeg -i 8_1_44100.wav -strict -2 -y out.mlp ffmpeg version N-109867-g5247dab6b1 Copyright (c) 2000-2023 the FFmpeg developers built with gcc 9 (Ubuntu 9.4.0-1ubuntu1~20.04.1) configuration: libavutil 58. 1.100 / 58. 1.100 libavcodec 60. 2.100 / 60. 2.100 libavformat 60. 2.100 / 60. 2.100 libavdevice 60. 0.100 / 60. 0.100 libavfilter 9. 1.100 / 9. 1.100 libswscale 7. 0.100 / 7. 0.100 libswresample 4. 9.100 / 4. 9.100 Guessed Channel Layout for Input Stream #0.0 : mono Input #0, wav, from '8_1_44100.wav': Duration: 00:00:10.00, bitrate: 352 kb/s Stream #0:0: Audio: pcm_u8 ([1][0][0][0] / 0x0001), 44100 Hz, 1 channels, u8, 352 kb/s Stream mapping: Stream #0:0 -> #0:0 (pcm_u8 (native) -> mlp (native)) Press [q] to stop, [?] for help Output #0, mlp, to 'out.mlp': Metadata: encoder : Lavf60.2.100 Stream #0:0: Audio: mlp, 44100 Hz, mono, s16, 128 kb/s Metadata: encoder : Lavc60.2.100 mlp size= 324kB time=00:00:09.99 bitrate= 265.5kbits/s speed= 146x video:0kB audio:324kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.000000% }}} {{{ ./ffmpeg -i out.mlp -f null - ffmpeg version N-109867-g5247dab6b1 Copyright (c) 2000-2023 the FFmpeg developers built with gcc 9 (Ubuntu 9.4.0-1ubuntu1~20.04.1) configuration: libavutil 58. 1.100 / 58. 1.100 libavcodec 60. 2.100 / 60. 2.100 libavformat 60. 2.100 / 60. 2.100 libavdevice 60. 0.100 / 60. 0.100 libavfilter 9. 1.100 / 9. 1.100 libswscale 7. 0.100 / 7. 0.100 libswresample 4. 9.100 / 4. 9.100 [mlp @ 0x561a02261640] Invalid channel 10 specified as output from matrix.
