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

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!

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

uncompressed RGB within MXF
by Kieran O Leary 27 Jan '19

27 Jan '19

Hi, I see that uncompressed RGB is not supported within MXF. I know that Resolve can create 10-bit RGB but only at HD resolution. I didn't see anything relating to uncompressed RGB in the UL list in mxfenc.c and I don't have an SMPTE account to get beyond the Paywall that would let me know what RGB pixel formats are possible within MXF in a general sense. I'm assuming that there isn't some option that I'm missing out on here, it just isn't supported? $ ./ffmpeg -f lavfi -i testsrc -pix_fmt gbrp10le -c:v copy out.mxf ffmpeg version N-92260-g3cc3cb663b Copyright (c) 2000-2018 the FFmpeg developers built with gcc 7 (Ubuntu 7.3.0-27ubuntu1~18.04) configuration: libavutil 56. 20.100 / 56. 20.100 libavcodec 58. 33.102 / 58. 33.102 libavformat 58. 19.102 / 58. 19.102 libavdevice 58. 4.106 / 58. 4.106 libavfilter 7. 37.100 / 7. 37.100 libswscale 5. 2.100 / 5. 2.100 libswresample 3. 2.100 / 3. 2.100 Input #0, lavfi, from 'testsrc': Duration: N/A, start: 0.000000, bitrate: N/A Stream #0:0: Video: rawvideo (RGB[24] / 0x18424752), rgb24, 320x240 [SAR 1:1 DAR 4:3], 25 tbr, 25 tbn, 25 tbc [mxf @ 0x56227a627880] track 0: could not find essence container ul, codec not currently supported in container Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted Stream mapping: Stream #0:0 -> #0:0 (copy) Last message repeated 1 times Best, Kieran.

Max rtbufsize Via dshow
by Gabriel Balaich 11 Jan '19

11 Jan '19

Up until a few days ago I had been running two capture cards, 1x4K card and 1x1080P card, I would encode both streams with a GTX 1080 no dropped frames no issues. But just recently I replaced the 1080P capture card with another 4K capture card to prep for a new camera and can't get things working gracefully. On my first test encoding 2x4K60 streams simultaneously I dropped frames starting the recording *and *ending the recording, but nothing in-between. Errors displayed: [dshow @ 000001499bb17180] real-time buffer [Video (00 Pro Capture HDMI 4K+)] [video input] too full or near too full (62% of size: 2147480000 [rtbufsize parameter])! frame dropped! [dshow @ 00000149944e7080] real-time buffer [AVerMedia HD Capture GC573 1] [video input] too full or near too full (62% of size: 2147480000 [rtbufsize parameter])! frame dropped! The obvious answer, according to the warning, would be increasing rtbufsize but I seem to have hit the cap... If I try to increase rtbufsize passed 2147.48M I get another error: [dshow @ 00000250df6c7080] Value 3000000000.000000 for parameter 'rtbufsize' out of range [0 - 2.14748e+09] [dshow @ 00000250df6c7080] Error setting option rtbufsize to value 3000M. video=AVerMedia HD Capture GC573 1:audio=SPDIF/ADAT (1+2) (RME Fireface UC): Result too large Is this a baked in limitation of FFmpeg or dshow? And if it is, why impose said limitation? Since then I've tried messing with other parts of my command and found that by re-arranging my inputs / outputs I can prevent frame drops upon starting a recording but I still can't end a recording without dropping a bunch of frames. Anyone know why re-arranging my inputs / outputs would prevent frames from dropping when starting a recording or affect anything? Is it possible to bypass the rtbufsize cap? Any other ideas? Here is my full command, Ignore the blank numbers next to -ss, will be used to sync outputs when everything is working: ffmpeg -y -hide_banner -thread_queue_size 9999 -indexmem 9999 -guess_layout_max 0 -f dshow -rtbufsize 2147.48M ` -i audio="Analog (1+2) (RME Fireface UC)" ` -thread_queue_size 9999 -indexmem 9999 -guess_layout_max 0 -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=50x50 ` -thread_queue_size 9999 -indexmem 9999 -guess_layout_max 0 -f dshow -video_size 3840x2160 -rtbufsize 2147.48M ` -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 -guess_layout_max 0 -f dshow -video_size 3840x2160 -rtbufsize 2147.48M ` -framerate 60 -pixel_format nv12 -i video="Video (00 Pro Capture HDMI 4K+)":audio="ADAT (3+4) (RME Fireface UC)" ` -map 2,0 -map 0 -c:v libx264 -r 25 -rc-lookahead 50 -forced-idr 1 -sc_threshold 0 -flags +cgop ` -force_key_frames "expr:gte(t,n_forced*2)" -preset ultrafast -pix_fmt nv12 -b:v 16K -minrate 16K -maxrate 16K -bufsize 16k ` -c:a aac -ar 44100 -b:a 384k -ac 2 -af "aresample=async=250" -vsync 1 -ss 00:00:00.000 ` -max_muxing_queue_size 9999 -f segment -segment_time 600 -segment_wrap 9 -reset_timestamps 1 ` -segment_format_options max_delay=0 C:\Users\djcim\Videos\Main\Discord\Discord%02d.ts ` -map 2,1 -map 1 -c:v libx264 -r 25 -rc-lookahead 50 -forced-idr 1 -sc_threshold 0 -flags +cgop ` -force_key_frames "expr:gte(t,n_forced*2)" -preset ultrafast -pix_fmt nv12 -b:v 16K -minrate 16K -maxrate 16K -bufsize 16k ` -c:a aac -ar 44100 -b:a 384k -ac 2 -af "aresample=async=250" -vsync 1 -ss 00:00:00.000 ` -max_muxing_queue_size 9999 -f segment -segment_time 600 -segment_wrap 9 -reset_timestamps 1 ` -segment_format_options max_delay=0 C:\Users\djcim\Videos\Main\Soundboard\Soundboard%02d.ts ` -map 3:0,3:1 -map 3:1 -c:v h264_nvenc -r 60 -rc-lookahead 120 -forced-idr 1 -strict_gop 1 -sc_threshold 0 -flags +cgop ` -force_key_frames "expr:gte(t,n_forced*2)" -preset: llhp -pix_fmt nv12 -b:v 250M -minrate 250M -maxrate 250M -bufsize 250M ` -c:a aac -ar 44100 -b:a 384k -ac 2 -af "pan=mono|c0=c0, aresample=async=250" -vsync 1 -ss 00:00:00.000 ` -max_muxing_queue_size 9999 -f segment -segment_time 600 -segment_wrap 9 -reset_timestamps 1 ` -segment_format_options max_delay=0 C:\Users\djcim\Videos\Main\Camera\Camera%02d.ts ` -map 4:0,4:1 -map 4:1 -c:v h264_nvenc -r 60 -rc-lookahead 120 -forced-idr 1 -strict_gop 1 -sc_threshold 0 -flags +cgop ` -force_key_frames "expr:gte(t,n_forced*2)" -preset: llhp -pix_fmt nv12 -b:v 250M -minrate 250M -maxrate 250M -bufsize 250M ` -c:a aac -ar 44100 -b:a 384k -ac 2 -af "atrim=0.086, asetpts=PTS-STARTPTS, aresample=async=250" -vsync 1 -ss 00:00:00.000 ` -max_muxing_queue_size 9999 -f segment -segment_time 600 -segment_wrap 9 -reset_timestamps 1 ` -segment_format_options max_delay=0 C:\Users\djcim\Videos\Main\Magewell\Magewell%02d.ts

running configure on SPARC
by Eric Thomas 12 Dec '18

12 Dec '18

Hello, I'm not sure this email went through the first time. My apologies if this is a repeat... I cannot figure out what I am missing, to get the configure script to generate the config.h file, which would then be used to build ffmpeg. Here is some system info: env PATH=/usr/xpg6/bin:/usr/ccs/bin:/usr/sfw/bin:/usr/bin:/usr/local/bin:/usr/sbin:/sbin LD_LIBRARY_PATH=/home/eric/ffmpeg/FFmpeg-4.0.2/lib:/usr/lib:/usr/local/lib uname –a SunOS devm 5.10 Generic_150400-61 sun4u sparc SUNW,Sun-Fire-V490 make –v GNU Make 3.81 gcc –v Reading specs from /usr/sfw/lib/gcc/sparc-sun-solaris2.10/3.4.3/specs Configured with: /sfw10/builds/build/sfw10-patch/usr/src/cmd/gcc/gcc-3.4.3/configure –prefix=/usr/sfw –with-as=/usr/ccs/bin/as –without-gnu-as –with-ld=/usr/ccs/bin/ld –without-gnu-ld –enable-language=c,c++ --enable-shared Thread model: posix gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath) Configure cmd bash ./configure –prefix=/home/eric/ffmpeg/FFmpeg-4.0.2 –extra-cflags=”fPIC” –arch=sparc –target-os=sun The configure script does not run to completion – I have to kill it with ‘Ctrl-z’, and I do not get a config.h file. I am not the administrator of this server, so I can only request upgrades. I am planning to request a gcc upgrade to 8.2 (latest). Can you help me identify what options I am missing to get ffmpeg to configure, and then compile? Thanks, Eric

Hello everybody Sorry for my delay in reply in my response. 1)I have attached a link for a small section of the flow that I capture https://drive.google.com/file/d/1c7IwXuu9GLMDo70A8gRyy1pUKntgxrM0/view?usp=… 2) I catpure multiple dvb-t or dvb-s signal with dvblast and his outgoing are rtp, then I use the rpt to transcoding the signal with ffmpeg mp2g to h264 and audio to aac. and republish it to my server. Thanks a lot for your help.
