#11017: Enhancing FFmpeg's playback support for MIDI files and other "instrument- free" music formats -----------------------------------+--------------------------------------- Reporter: peteroupc | Type: enhancement Status: new | Priority: normal Component: ffmpeg | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+--------------------------------------- The following is a request to enhance FFmpeg's support for playing MIDI files (.mid). Currently, FFmpeg relies on `libmodplug` to synthesize MIDI, MOD, and other music formats to audio. However, `libmodplug` appears not to be actively developed; the last commit at the time of writing was made in January 30, 2022, so more than two years ago. Since future development on `libmodplug` is not forthcoming, and I don't know FFmpeg's plans to adopt a replacement for that library, I file this enhancement request. The following are features I would like FFmpeg to support, to the extent that it's not already supported: - Support for software synthesis of MIDI files using other instrument source formats besides Timidity's patch format (e.g., downloadable sounds [DLS]; SoundFont2 .sf2; OPL2, OPL3, and other FM instrument banks). In this sense, the source code in the projects ''fluidsynth'', ''libADLMIDI'', ''libOPNMIDI'', and ''OPL3BankEditor'' may be useful here. Moreover, Timidity's patch format appears to support SoundFont 2 already, but it's cumbersome in `libmodplug` to specify a directory containing `timidity.cfg` as opposed to specifying the SoundFont file (.sf2) directly. - Seeking of MIDI files such that a pause and resume function can be offered by a media player. - Support for popular looping conventions seen in MIDI files. This request also applies to .abc and other "instrument-free" music formats as it does to MIDI files. Just as an aside, a public-domain music synthesis library and instrument banks (https://peteroupc.github.io/music.html) would greatly help improve MIDI playback support across the open-source ecosystem; however, I don't insist on that for purposes of this issue. -- Ticket URL: <https://trac.ffmpeg.org/ticket/11017> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#11400(avfilter:new): Consider adding a fuzzer for filtergraphs

#11400: Consider adding a fuzzer for filtergraphs -------------------------------------+------------------------------------- Reporter: somehacker | Type: | enhancement Status: new | Priority: normal Component: avfilter | Version: git- Keywords: fuzzer | master fuzzing test filters | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Hi! I have started developing a fuzzer for filtergraphs which you can read about here: https://personnumber3377.github.io/projects/fuzzing_ffmpeg_avfilter_graph_p… . I made a fork of ffmpeg here: https://github.com/personnumber3377/ffmpeg which has the fuzzer source code. I already found a couple of bugs with it (for example https://trac.ffmpeg.org/ticket/11395) I don't know how worth it it is to fuzz filtergraphs, because they shouldn't be attacker controlled anyway since usually the filtergraphs are specified by developers when using ffmpeg in other projects and only the input and output files should be controlled by users (and possible attackers). My fuzzer source code is based on the example code in doc/examples/decode_filter_video.c and doc/examples/decode_filter_audio.c . My fuzzer works by first validating the filtergraph for syntax by calling avfilter_graph_parse_ptr and then continuing if it is valid and then just having a small video file in memory which is then read with fmemopen similar to an actual file and then processed with the fuzzer generated filtergraph string. I am only getting one or two execs a second when running my fuzzer even though the in-memory video file is just a couple of kilobytes. Maybe someone can optimize it further or maybe do a complete rewrite of this even??? Thanks in advance for your ideas and thoughts! -- Ticket URL: <https://trac.ffmpeg.org/ticket/11400> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#11383(ffmpeg:new): Unable to achieve specified fps with AVFoundation camera on iOS

#11383: Unable to achieve specified fps with AVFoundation camera on iOS -------------------------------------+------------------------------------- Reporter: Dex Devlon | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: 6.0.1 Keywords: ios | Blocked By: avfoundation | Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- My goal was to stream 1080p at 120fps from the iPhone's main camera to a local network server with minimal latency. However, I encountered issues when trying to achieve the specified frame rates using AVFoundation. With the BGR0 pixel format, I’m seeing around 57fps when the camera is set to 60fps mode, while with the NV12 pixel format, I’m getting 60fps as expected in 60fps mode. The main problem arises with 120fps and 240fps modes, where I’m only able to achieve between 70fps and 77fps, which is far below the expected frame rates. Interestingly, with an earlier version of FFmpeg, I was able to achieve just under 120fps in 1080p at 240fps mode. Also of note, these tests were done on iPhone 14 Plus main back camera, the application built using ffmegkit. The expected behavior is to achieve the specified frame rate in the corresponding frame rate mode using AVFoundation.
