Has flag hybrid_fragmented flag (yet) been added to ffmpeg release?
by Bo Berglund 26 Sep '25

26 Sep '25

The hybrid_fragmented flag is used to enable viewers to read an mp4 file while it is being wrtitten according to the documentation here: https://ffmpeg.org/ffmpeg-formats.html But has it been released yet and in that case from which version is it available? I really need to be able to start viewing mp4 files before they are closed by the writer.... -- Bo Berglund Developer in Sweden

video capture example code
by Stefan Oltmanns 04 Sep '25

04 Sep '25

Hi, I was looking for some minimal example code to capture video with libavdevice. What I would like to do is (for v4l2, avfoundation and dshow): -Get a list of available capture devices -Get a list of supported formats/resolutions for a capture device -Capture from a device with a specific format/resolution and get the data (raw uncompressed without any processing, just like it came from the device, if possible with a callback for each frame) Does somebody know some example code for that? All I found is decades old and won't compile with recent ffmpeg. Best regards Stefan

Wrong encoding in output
by Ulf Zibis 02 Sep '25

02 Sep '25

Hi, in the following output you can see in the metadata tag "Album", that the character '°' was printed as unknown encoding. This is, because here on Ubuntu the default system encoding is UTF-8, but ffmpeg and ffprobe output the data in ISO-8859-1 encoding. In terminal output this is not really a big problem, but if the output is processed with another program, e.g. Python script, which uses the system default encoding, an encoding exception occurs, which breaks the program. To me this looks like a bug. $ ffprobe 12-suzanne_vega-song_of_sand.flac ffprobe version 6.1.1-3ubuntu5 Copyright (c) 2007-2023 the FFmpeg developers built with gcc 13 (Ubuntu 13.2.0-23ubuntu3) configuration: --prefix=/usr --extra-version=3ubuntu5 --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --arch=amd64 --enable-gpl --disable-stripping --disable-omx --enable-gnutls --enable-libaom --enable-libass --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libcodec2 --enable-libdav1d --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libglslang --enable-libgme --enable-libgsm --enable-libharfbuzz --enable-libmp3lame --enable-libmysofa --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzimg --enable-openal --enable-opencl --enable-opengl --disable-sndio --enable-libvpl --disable-libmfx --enable-libdc1394 --enable-libdrm --enable-libiec61883 --enable-chromaprint --enable-frei0r --enable-ladspa --enable-libbluray --enable-libjack --enable-libpulse --enable-librabbitmq --enable-librist --enable-libsrt --enable-libssh --enable-libsvtav1 --enable-libx264 --enable-libzmq --enable-libzvbi --enable-lv2 --enable-sdl2 --enable-libplacebo --enable-librav1e --enable-pocketsphinx --enable-librsvg --enable-libjxl --enable-shared libavutil 58. 29.100 / 58. 29.100 libavcodec 60. 31.102 / 60. 31.102 libavformat 60. 16.100 / 60. 16.100 libavdevice 60. 3.100 / 60. 3.100 libavfilter 9. 12.100 / 9. 12.100 libswscale 7. 5.100 / 7. 5.100 libswresample 4. 12.100 / 4. 12.100 libpostproc 57. 3.100 / 57. 3.100 Input #0, flac, from '12-suzanne_vega-song_of_sand.flac': Metadata: artist : Suzanne Vega title : Song Of Sand date : 1992 track : 12 genre : Pop Language : English Rip Date : 2012-04-19 Retail Date : 1992-09-08 Media : CD Encoder : FLAC 1.2.1 Ripping Tool : Exact Audio Copy (Secure Mode) Release Type : Normal release ORGANIZATION : A&M Records Album : 99.9F� <== unknown character because of wrong encoding Duration: 00:03:04.93, start: 0.000000, bitrate: 600 kb/s Stream #0:0: Audio: flac, 44100 Hz, stereo, s16 -Ulf

ISSUE ABOUT VIDEO BITRATE
by Hervé ANSELME 30 Aug '25

30 Aug '25

Hello all, I am using the release 8.0 of ffmpeg/ffprobe, running on Windows 11 Family OS. I executed the following command : ffmpeg -i "initial movie.mkv" -y -loglevel error -sn ^ -map 0:a:0 -acodec aac -ar 44100 -b:a 128k ^ -map 0:v:0 -vcodec libsvtav1 -vf "scale=768:432" -sws_flags lanczos+accurate_rnd -b:v 1200k -minrate 1200k ^ -svtav1-params "lossless=lower:nal-hrd=cbr:force-cfr=1:vbv-maxrate=1200k:vbv-bufsize=2400k" ^ -bufsize 2400k "final movie.mkv" then, to see the result in the final film, regarding the video characteristics, I executed : ffprobe -v error -select_streams v -show_entries stream=codec_name,width,height,avg_frame_rate -of default=noprint_wrappers=1 "final movie.mkv" which result is : bit_rate=930911 codec_name=av1 width=768 height=432 avg_frame_rate=25/1 which raises the question : how is it that there is such a large difference, between the desired video bitrate (1200k) and the actual video bitrate obtained (930911 = 930k) ? How should I modify my command line to obtain an effective video bitrate that is, if not equal, at least as close as possible, to 1200k ? Thank you in advance for your replies and advices. Cdlt, HA

Option -nostdin is missing in help
by Ulf Zibis 27 Aug '25

27 Aug '25

Hi, if I run ffmpeg -h long (of full) only option -stdin is listed, but not -nostdin. As the first is the default and does not change anything, it would be more useful to list the latter. At https://ffmpeg.org/ffmpeg-all.html#Main-options you could add a hint, that -nostdin is often needed when using ffmpeg in a bash script, where input comes from a pipe, loop or other virtual stream. Also there it is listed as "standard option", but under -help it is listet as "advanced option". -Ulf

Transcoding of 3 second video took very long time and result is not playable
by Ulf Zibis 24 Aug '25

24 Aug '25

Hi, Transcoding of this 3.39 second video <http://www.jugkoeln.de/Projects/ffmpeg/20241130_000929_01.mp4> took very long time (speed=0.00316x). Additionally the size of the result <http://www.jugkoeln.de/Projects/ffmpeg/20241130_000929_01_out.mp4> was 6 times of the original, even it was scaled by half. And the result is not playable correctly with VLC media player and ffplay. $ for Video in *.MP4 *.mp4; do ffmpeg -i $Video -c:a copy -vf scale=iw/2:ih/2 -movflags +faststart Komp/$Video; done ffmpeg

SELECT AUDIO TRACK BY LANGUAGE
by Hervé ANSELME 22 Aug '25

22 Aug '25

Hello all, for information I use ffmpeg version 6.1. To re-encode a film, you can select the audio track by language ; for example, if we want the English language, we put in the command line : -map 0:m:language:eng This works well if there is only 1 English audio track ; but what if the source film (the one we re-encode) contains several English audio tracks ? How do we select 1 track from the various English audio tracks ? Knowing that I want to keep just 1 audio track ; there's no point in having more than one. Thank you in advance for your answers and advice. Regards, HA

ffmpeg hanging indefinately if streaming connection dies
by Andrew Wood 22 Aug '25

22 Aug '25

Ive just upgraded to ffmpeg 5.1.6 (the version that comes with Debian 12) from an older version. A command which has worked fine for years recording a camera rtsp stream and automatically exiting if the camera connection dies has now started hanging forever if the camera stops responding. Has something been altered in ffmpeg and is there a command option to make it work as before? I tried -xerror but that is causing it to exit due to 'Non-monotonous DTS in output stream 0:0; previous: 0, current: 0; aborting' even when the stream is working Thanks

Whisper in ffmpeg 8
by Bernhard Döbler 14 Aug '25

14 Aug '25

Hi, yesterday, news made the round, that ffmpeg 8 is going to be released, soon, and it will contain whisper, an AI software that can understand spoken text and create subtitles. Their github page https://github.com/ggml-org/whisper.cpp says they offer a handful of models. Model Disk Mem tiny 75 MiB ~273 MB base 142 MiB ~388 MB small 466 MiB ~852 MB medium 1.5 GiB ~2.1 GB large 2.9 GiB ~3.9 GB How does this work? Will all of this be compiled into the ffmpeg binary?
