Recording audio from mic and speakers from commandline
by Mohan G 28 Sep '21

28 Sep '21

Hi, I am using ffmpeg version 2.4.7 on Fedora-21 workstation. I want to record audio, simultaneously from mic and speakers as separate streams. I am using the following command for it. ffmpeg -f alsa -i pulse -f alsa -i default -acodec libmp3lame -map 0:0 -map 1:0 outfile.mkv But after executing this command in terminal, I have to goto "Volume Control" settings in GUI, then goto "Recording" tab, change the "capture from" of one channel to "Built-in Audio Analog Stereo" (i.e., Mic) and the "capture from" of another channel to "Monitor of Built-in Audio Analog Stereo" (i.e., Speakers). But how can this be done completely from command-line, for automating it to use in scripts. - Mohan

Dears, How to have a secure connection with username and password while broadcasting "UPD" I've use this command ffmpeg -f dshow -video_size 1280x720 -rtbufsize 702000K -framerate 30 -i video="Video (00-0 Pro Capture Quad HDMI)" -r 30 -threads 4 -vcodec libx264 -crf 0 -preset ultrafast -f mpegts "udp://username:password@192.168.1.12:6666" but it didn't work can you advice me plz.

Unable To Transcode 8 sources simultaneously Real Time In One Instance
by Gabriel Balaich 07 Jun '19

07 Jun '19

I'm trying to record 8 sources (3 Video + 5 audio) simultaneously and synchronized, however I can't seem to get it to transcode real time in one instance. Sample command: ffmpeg -y ` -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -video_size 3440x1440 -framerate 100 ` -pixel_format nv12 -i video="Video (Pro Capture)":audio="ADAT (3+4) (RME Fireface UC)" ` -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -video_size 3840x2160 -framerate 60 ` -pixel_format nv12 -i video="AVerMedia HD Capture GC573 1":audio="SPDIF/ADAT (1+2) (RME Fireface UC)" ` -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -video_size 1920x1080 -framerate 60 ` -pixel_format yuv420p -i video="Game Capture HD60 Pro (Video) (#01)":audio="Game Capture HD60 Pro (Audio) (#01)" ` -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -i audio="Analog (1+2) (RME Fireface UC)" ` -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -i audio="ADAT (5+6) (RME Fireface UC)" ` -c:v h264_nvenc -preset: llhp -pix_fmt nv12 -rc-lookahead 100 -b:v 288M -minrate 288M -maxrate 288M -bufsize 288M ` -c:a aac -ar 44100 -b:a 384k -vsync 1 -max_muxing_queue_size 9999 ` -map 0:0,0:1 -map 0:1 -map 1:0,1:1 -map 1:1 -map 2:0,2:1 -map 2:1 -map 3 -map 4 ` C:\Users\djcim\Videos\FFmpeg\FFmpeg.ts Basically the recording starts with "speed" around .5x and slowly creeps its way towards 1x, meanwhile my ram usage is ever increasing. Once it gets to around .9-.95x it hits a standstill and eventually my ram caps out and the recording speed tanks, frames start dropping, and my whole system slows down. I have 32GB of system memory, and by the end of this process this single instance of FFmpeg is using 28GB+! I'm not quite sure how this is possible when -rtbufsize is only set to 2GB per source (11GB total), what is filling up all that space? If I remove any one of the inputs, even just an audio sources linked to one of the capture cards, the recording will hit real time transcoding before my RAM is completely saturated (with a peak usage of 16GB). When 1x speed is achieved, which takes about 1 minute, my RAM usage slowly decreases before it plateaus around 9GB as the recording continues to transcode real time with no issues. So basically "it works" when I remove even just one audio or video source, though it still takes a hot second to get up to realtime recording which I find odd. Lowing bitrate of audio and or video also affects transcoding speed but only if I put it extremely low, like 1M per source as opposed to 288M. In terms of raw throughput this should have a larger effect than simply removing one of the audio streams, but it doesn't Separating the outputs to their own files like this seemingly heeds no beneficial effect: ffmpeg -y ` -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -video_size 3440x1440 -framerate 100 ` -pixel_format nv12 -i video="Video (Pro Capture)":audio="ADAT (3+4) (RME Fireface UC)" ` -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -video_size 3840x2160 -framerate 60 ` -pixel_format nv12 -i video="AVerMedia HD Capture GC573 1":audio="SPDIF/ADAT (1+2) (RME Fireface UC)" ` -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -video_size 1920x1080 -framerate 60 ` -pixel_format yuv420p -i video="Game Capture HD60 Pro (Video) (#01)":audio="Game Capture HD60 Pro (Audio) (#01)" ` -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -i audio="Analog (1+2) (RME Fireface UC)" ` -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -i audio="ADAT (5+6) (RME Fireface UC)" ` -thread_queue_size 9999 -indexmem 9999 -r 25 -f lavfi -rtbufsize 2147.48M -i color=c=black:s=256x120 ` -map 0:0,0:1 -map 0:1 -c:v h264_nvenc -preset: llhp -r 100 -rc-lookahead 100 -pix_fmt nv12 -b:v 288M -minrate 288M ` -maxrate 288M -bufsize 288M -c:a aac -ar 44100 -b:a 384k -vsync 1 -max_muxing_queue_size 9999 ` C:\Users\djcim\Videos\FFmpeg\MW\MW.ts ` -map 1:0,1:1 -map 1:1 -c:v h264_nvenc -preset: llhp -r 60 -rc-lookahead 60 -pix_fmt nv12 -b:v 288M -minrate 288M ` -maxrate 288M -bufsize 288M -c:a aac -ar 44100 -b:a 192k -vsync 1 -max_muxing_queue_size 9999 ` C:\Users\djcim\Videos\FFmpeg\AM\AM.ts ` -map 2:0,2:1 -map 2:1 -c:v h264_nvenc -preset: llhp -r 60 -rc-lookahead 60 -pix_fmt yuv420p -b:v 288M -minrate 288M ` -maxrate 288M -bufsize 288M -c:a aac -ar 44100 -b:a 384k -vsync 1 -max_muxing_queue_size 9999 ` C:\Users\djcim\Videos\FFmpeg\EL\EL.ts ` -map 5,3 -map 3 -c:v h264_nvenc -preset: llhp -r 25 -rc-lookahead 25 -pix_fmt nv12 -b:v 16K -minrate 16K ` -maxrate 16K -bufsize 16K -c:a aac -ar 44100 -b:a 384k -vsync 1 -max_muxing_queue_size 9999 ` C:\Users\djcim\Videos\FFmpeg\CP\CP.ts ` -map 5,4 -map 4 -c:v h264_nvenc -preset: llhp -r 25 -rc-lookahead 25 -pix_fmt nv12 -b:v 16K -minrate 16K ` -maxrate 16K -bufsize 16K -c:a aac -ar 44100 -b:a 384k -vsync 1 -max_muxing_queue_size 9999 ` C:\Users\djcim\Videos\FFmpeg\SB\SB.ts Now the interesting part is that when I record all 5 sources in separate terminals / instances of FFmpeg, but still concurrently, starting all 5 sessions in less than 2 seconds, there are zero issues (basically no wait at all for real time transcoding).

I scoured the documentation for any options that might help me but every single one I tried fell short, anybody have any ideas? I'll attach the full console output of the first command in this email, but I don't feel like console output as text best illustrates the situation as the stats bar, which displays speed, doesn't update as it changes. Therefore I made a short video of my console output that I believe should give you a better picture: https://www.youtube.com/watch?v=zdEPS7u4rao Also you're going to see a lot of frame drops when I start and end my recordings, I believe this is an issue with the maximum size of rtbufsize, and it is something I plan to troubleshoot by patching the code to bypass said limit later this week. I do not believe it is having any effect on the issue at hand as raising the my buffer size shouldn't increase transcoding speed, if anything it would have the opposite effect. Here is the uncut console output, it is different from the one in the video, I let this one run until my ram was fully saturated: PS C:\Users\djcim> ffmpeg -y ` >> -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -video_size 3440x1440 -framerate 100 ` >> -pixel_format nv12 -i video="Video (Pro Capture)":audio="ADAT (3+4) (RME Fireface UC)" ` >> -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -video_size 3840x2160 -framerate 60 ` >> -pixel_format nv12 -i video="AVerMedia HD Capture GC573 1":audio="SPDIF/ADAT (1+2) (RME Fireface UC)" ` >> -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -video_size 1920x1080 -framerate 60 ` >> -pixel_format yuv420p -i video="Game Capture HD60 Pro (Video) (#01)":audio="Game Capture HD60 Pro (Audio) (#01)" ` >> -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -i audio="Analog (1+2) (RME Fireface UC)" ` >> -thread_queue_size 9999 -indexmem 9999 -f dshow -rtbufsize 2147.48M -i audio="ADAT (5+6) (RME Fireface UC)" ` >> -c:v h264_nvenc -preset: llhp -pix_fmt nv12 -rc-lookahead 100 -b:v 288M -minrate 288M -maxrate 288M -bufsize 288M ` >> -c:a aac -ar 44100 -b:a 384k -vsync 1 -max_muxing_queue_size 9999 ` >> -map 0:0,0:1 -map 0:1 -map 1:0,1:1 -map 1:1 -map 2:0,2:1 -map 2:1 -map 3 -map 4 ` >> C:\Users\djcim\Videos\FFmpeg\FFmpeg.ts ffmpeg version N-92953-gad0d5d7516 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 8.2.1 (GCC) 20181201 configuration: --enable-gpl --enable-version3 --enable-sdl2 --enable-fontconfig --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libfreetype --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libtheora --enable-libtwolame --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libzimg --enable-lzma --enable-zlib --enable-gmp --enable-libvidstab --enable-libvorbis --enable-libvo-amrwbenc --enable-libmysofa --enable-libspeex --enable-libxvid --enable-libaom --enable-libmfx --enable-amf --enable-ffnvcodec --enable-cuvid --enable-d3d11va --enable-nvenc --enable-nvdec --enable-dxva2 --enable-avisynth --enable-libopenmpt libavutil 56. 25.100 / 56. 25.100 libavcodec 58. 43.100 / 58. 43.100 libavformat 58. 25.100 / 58. 25.100 libavdevice 58. 6.101 / 58. 6.101 libavfilter 7. 47.100 / 7. 47.100 libswscale 5. 4.100 / 5. 4.100 libswresample 3. 4.100 / 3. 4.100 libpostproc 55. 4.100 / 55. 4.100 Guessed Channel Layout for Input Stream #0.1 : stereo Input #0, dshow, from 'video=Video (Pro Capture):audio=ADAT (3+4) (RME Fireface UC)': Duration: N/A, start: 10389.535000, bitrate: N/A Stream #0:0: Video: rawvideo (NV12 / 0x3231564E), nv12, 3440x1440, 100 fps, 100 tbr, 10000k tbn, 10000k tbc Stream #0:1: Audio: pcm_s16le, 44100 Hz, stereo, s16, 1411 kb/s [dshow @ 000002a32550efc0] real-time buffer [Video (Pro Capture)] [video input] too full or near too full (63% of size: 2147480000 [rtbufsize parameter])! frame dropped!

Hi All, I'm streaming a live channel and I want to use ffmpeg to monitor the stream, what I need to check is when the image is frozen. Is there a way yo achieve this? I've read that I can use blend function, but not sure how. Thanks!

FFmpeg is shutting down when concating segmented files and outputting to UDP
by Sagar Lakhani 28 Mar '19

28 Mar '19

hello, I am new to this community, i have used ffmpeg in my server in which i have live streams and i am segmenting them and then storing after a while i concat the segmented files and then output these to udp. Firstly i got a problem of open file limit which i had solved but then again i got a problem in which the ffmpeg shut down automatically in 2-3 days, time is not random. I am using xeon processor with 16 gb ram, ffmpeg version 3.4. earlier i have noticed that cpu utility increases but exactly don't knw the reason. i have also generated the log file with -report option but these log files are generated in order of 100s of gbs but i have managed to grab some end file lines and there is no error message before quitting, i also tried hardware accel qsv but i am still getting same problem. i have doubt that this is bug in ffmpeg. Please help me with solving this issue. Thanks, Regards Sagar

Meaning of ffprobe output
by Ulf Zibis 11 Mar '19

Hi, can anybody explain me the data of ffprobe, I don't find enough hints in the docu. E.g.: $ ffprobe CYD_copy.vob Input #0, mpeg, from 'CYD_copy.vob': Duration: 01:16:20.74, start: 0.500000, bitrate: 7068 kb/s Stream #0:0[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 256 kb/s Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bt470bg, top first), 704x576 [SAR 12:11 DAR 4:3], 25 fps, 25 tbr, 90k tbn, 50 tbc What is: tv bt470bg tbr tbn tbc I'm also wondering, why Stream #0:1 is the video, as it was created by $ ffmpeg -ss 00:03 -t 01:16:20 -i "concat:001-C001/CYD-001.vob|001-C002/CYD-001.vob|..." -movflags +faststart -c copy CYD_copy.vob from files like $ ffprobe 001-C001/CYD-001.vob Input #0, mpeg, from '/home/ich/Videos/dvdrip-data/CYD/vob/001-C001/CYD-001.vob': Duration: 00:00:20.41, start: 0.231578, bitrate: 74597 kb/s Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bt470bg, top first), 704x576 [SAR 12:11 DAR 4:3], 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0:1[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 256 kb/s After transcode with $ ffmpeg -i CYD_copy.vob -movflags +faststart -vf atadenoise -c:v libx264 -c:a libmp3lame -q:a 4 CYD_atadenoise_H.264.mp4 I get: $ ffprobe CYD_atadenoise_H.264.mp4 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'CYD_atadenoise_H.264_mp3-q4.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf57.83.100 Duration: 01:16:20.42, start: 0.000000, bitrate: 1403 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 704x576 [SAR 12:11 DAR 4:3], 1276 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc (default) Metadata: handler_name : VideoHandler Stream #0:1(und): Audio: mp3 (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 119 kb/s (default) Metadata: handler_name : SoundHandler Does 50 tbc mean, that I still have 50 interlaced half-frames per second?

Non-English (Chinese) file and filepath names in FFmpeg Command Line
by Wayne 05 Mar '19

05 Mar '19

Any way to do this in C#? I have resorted to temporarily renaming those file names/filepaths to English and then renaming back to the original language once rendering is completed.

Streaming overseas
by Louis Letourneau 19 Feb '19

19 Feb '19

I was wondering if anyone had experience streaming 720p ~5000kbit/s video overseas successfully? If so which protocol did you use? I'm trying to stream between Stockholm sweden to toronto canada. Using mpegts over tcp, I sometimes get so many retries that the bandwith falls below 5MBit/s for many seconds. The source and destination buffers are 16MBytes I wanted to try pro-mpeg, but ffmpeg only has it as a send protocol not receive (or I missed something) I can't use HLS/MPEG-Dash which would be my first choice for reasons at the source I can't get into. My 2 choices I think 1- Spawn an amazon or whatever cloud instance as close as possible and grab the stream THEN convert to HLS and send it overseas 2- Use another protocol I don't know.... Thanks for the input Louis

Hello everybody, I am trying to use FFMPEG ( 3.4 version) to transfert HDR video specifications (x265.mp4 videos). I have seen on other forums command lines that I tried to test for me but I never have succesfull results. I want to use Nvidia options (NVENC/SCALE_NPP/or other) because I have a P4 graphic card.
