Transmux .m4a file, keep metadata, copy video stream
by Sarah Mogielnicki 09 Aug '19

09 Aug '19

I'd like to transmux an .m4a file, keep its (known and custom) metadata, and keep its video stream. The video stream has a JPEG image in it, which is the "album art" for the audio track. If I use this command: ffmpeg -i input.m4a -movflags +faststart -movflags use_metadata_tags -c:a copy -c:v copy output.m4a the video stream does not copy to output.m4a, but the file is transmuxed and all of the metadata is copied. If I use this command: ffmpeg -i input.m4a -movflags +faststart -c:a copy -c:v copy output.m4a the video stream copies to output.m4a, and the file is transmuxed, but (obviously) the metadata is not copied. Is there a way to achieve all three goals? Sarah

Hi, I have a server to access the audio stream(fmt g722).When I use ffmpeg to convert the stream to aac( ffmpeg -thread_queue_size 128 -f g722 -i test/01334516771/1/alive -acodec aac -f flv rtmp://127.0.0.1:8080/myapp/01334516771_1_live) I only get noise.below is the ffmpeg's output [go@tdsg vavms]$ ffmpeg -thread_queue_size 128 -f g722 -i test/01334516771/1/alive -acodec aac -f flv rtmp://127.0.0.1:8080/myapp/01334516771_1_live ffmpeg version 3.4.2 Copyright (c) 2000-2018 the FFmpeg developers built with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-18) configuration: --disable-x86asm libavutil 55. 78.100 / 55. 78.100 libavcodec 57.107.100 / 57.107.100 libavformat 57. 83.100 / 57. 83.100 libavdevice 57. 10.100 / 57. 10.100 libavfilter 6.107.100 / 6.107.100 libswscale 4. 8.100 / 4. 8.100 libswresample 2. 9.100 / 2. 9.100 Input #0, g722, from 'test/01334516771/1/alive': Duration: N/A, bitrate: 64 kb/s Stream #0:0: Audio: adpcm_g722, 16000 Hz, mono, s16, 64 kb/s Stream mapping: Stream #0:0 -> #0:0 (adpcm_g722 (g722) -> aac (native)) Press [q] to stop, [?] for help Output #0, flv, to 'rtmp://127.0.0.1:8080/myapp/01334516771_1_live': Metadata: encoder : Lavf57.83.100 Stream #0:0: Audio: aac (LC) ([10][0][0][0] / 0x000A), 16000 Hz, mono, fltp, 69 kb/s Metadata: encoder : Lavc57.107.100 aac [flv @ 0x385a3c0] Failed to update header with correct duration.55x [flv @ 0x385a3c0] Failed to update header with correct filesize. size= 261kB time=00:00:29.95 bitrate= 71.3kbits/s speed=0.256x I found the speed is a little low. should I set some args to make the sound?

MXF, OP1A, DNxHD - Creates corrupted (Potential bug?)
by Mark O'Shea 08 Aug '19

08 Aug '19

Hi, all (apologies if this is a duplicate email, I wasn't subscribed to the mailing list so not sure if it went through). In advance thank you for any help! I've been trying to generate some DNxHR's with additional metadata as requested by a client, these are: reel_name:XXXX_XXX_XXXXX timecode:##:##:##:## I've been using FFMPEG so that it is scriptable but have run into what I think may be a bug when using the mxf_opatom option. The command I'm running: ffmpeg -y -r 24 -start_number 1001 -i input_exr_sequence.%04d.exr -vf colormatrix=bt601:bt709 -an -timecode 12:44:54:20 -minrate:v 36M -b:v 36M -c:v dnxhd -maxrate:v 36M -pix_fmt yuv422p -vf scale=in_range=limited:out_range=full -color_range 2 -f mxf_opatom -metadata reel_name=xxxx output.mxf This generates an MXF which opens fine in AVID, but not in other NLE's. Final Cut Pro + Adobe Premiere all won't allow it to be imported and reject the media as corrupt. Davinci Resolve will load up the footage but with a green line across the bottom (potential corrupt footer?) e.g: [image: geen_line.png] When I export the same file from adobe media encoder, the MXF works across all the above NLE's listed. I've attached an FFPROBE of the MXFs as .txt files on this email. I can send over some example MXF files if needed! Note at the very top of the FFMPEG MXF metadata: [dnxhd @ 0x7fb203001800] frame size changed: 1920x1088 -> 1920x1080 I think this may be the corruption but I have no idea how to fix it. I've tried using raw2bmx in conjunction with FFMPEG to: - Create RAW DNxHD stream with FFMPEG - Wrap in MXF with raw2bmx, injecting metadata (Can't get this working with the reel_name) Command to convert to raw data: ffmpeg -y -r 24 -start_number 1001 -i input_exr_sequence.%04d.exr -vf colormatrix=bt601:bt709 -an -timecode 12:44:54:20 -minrate:v 36M -b:v 36M -c:v dnxhd -maxrate:v 36M -pix_fmt yuv422p -vf scale=in_range=limited:out_range=full -color_range 2 -f mxf_opatom -metadata reel_name=xxxx output.mxf Command to wrap as MXF: raw2bmx -t op1a -o ./from_raw_metadata2.mxf -y 12:44:54:20 -a 16:9 --transfer-ch bt709 --coding-eq bt709 --color-prim bt709 --color-siting bt601 --vc3_1080p_1253 output.dnxhd This gives me a working DNxHD MXF but without the reel_name metadata needed. I'm really at a loss now as to how to get these DNxHD MXFs generating with an additional metadata key and not be corrupt! All help and advice is really appreciated!

Display statistics on decode error
by Remi Achard 08 Aug '19

08 Aug '19

Hi, I would like to use ffmpeg to check video files integrity in the sense that every frame can be successfully decoded. The command line I’m using looks like this : ffmpeg -v error -xerror -i /my/video/path -f null - It works but don’t give any clue on where the error was in the stream. [prores @ 0x7f9761812e00] invalid plane data size Last message repeated 78 times /my/video/path: corrupt decoded frame in stream 0 Ideally, I want to know at what frame the error occurred, to do this I proposed a patch ( http://ffmpeg.org/pipermail/ffmpeg-devel/2019-July/246498.html) that seems to work ok. The idea is to only show where the decoding failed without printing each and every frame statistic along the way (to keep reports and buffer from overflowing). The command looks like this (notice the verbose log level because the final statistics are logged as verbose level) : ffmpeg -v verbose -xerror -i /my/video/path -f null - [prores @ 0x7fc1dc007c00] ac tex damaged 2049, 2048 [prores @ 0x7fc1dc007c00] invalid plane data size Last message repeated 78 times /my/video/path: corrupt decoded frame in stream 0 video:1034kB audio:7810kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown Input file #0 (/my/video/path): Input stream #0:0 (video): 1976 packets read (1648274256 bytes); 1975 frames decoded; Input stream #0:1 (audio): 3997 packets read (11995584 bytes); 3997 frames decoded (3998528 samples); Input stream #0:2 (audio): 48 packets read (147072 bytes); Input stream #0:3 (data): 0 packets read (0 bytes); Total: 6021 packets (1660416912 bytes) demuxed Output file #0 (pipe:): Output stream #0:0 (video): 1975 frames encoded; 1975 packets muxed (1058600 bytes); Output stream #0:1 (audio): 3997 frames encoded (3998528 samples); 3997 packets muxed (7997056 bytes); Total: 5972 packets (9055656 bytes) muxed [AVIOContext @ 0x7fc1dd800080] Statistics: 1687982697 bytes read, 1827 seeks Conversion failed! With this I know that error occurred near frame 1975. Is there a way to already achieve this with ffmpeg-master ? (Sorry I realise I should have posted here first) Thanks,

converting apple pro res 422 to H.265 pushes red/changes color
by Uwe Gross (BLOOMBERG/ FRANKFURT) 08 Aug '19

08 Aug '19

Hi, im trying to convert an exported .mov file thats Prores 420 10 bit LE, 709 color space with the H.265 main preset in ffworks. When I encode the file with h.264 all is good and gives me great quality. When I do the same for h.265 (didnt pick 10 or 12 bit preset) using no profile (like high, main etc), preset for slower encoding, CRF = 25 I get an Ok file but with too much red color which is not in the original and not coming out when I use h.264. No other settings altered inn the preset So its like the whole picture has pushed reds. Is this a known issue perhaps or a simply thing to fix with a setting. The other colors are ok its just that red comes out wrong. If needed I can provide example images but I have the feeling this is a known issue, thanks Best Regards Uwe Gross Technology Services & Solutions 24x7 Customer Support: +44 207330 7500 * www.bloombergsoftware.com *

DeckLink Duo 2 duplex_mode doesn't work
by Rik Roukens 07 Aug '19

Hi All, I'm using a DeckLink Duo 2 card which supports 4 individual in or outputs, but by default is set to Full duplex mode (input from sdi 1 is output on sdi 3, input from sdi 2 is output on sdi 4). I'm running Ubuntu Server 18.04 with the following ffmpeg build: ffmpeg version 4.1.4 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 7 (Ubuntu 7.4.0-1ubuntu1~18.04.1) configuration: --prefix=/home/ladmin/ffmpeg_build --pkg-config-flags=--static --extra-cflags='-I/home/ladmin/ffmpeg_build/include -I/home/ladmin/ffmpeg_sources/BMD_SDK/include' --extra-ldflags=-L/home/ladmin/ffmpeg_build/lib --extra-libs='-lpthread -lm' --bindir=/home/ladmin/bin --enable-gpl --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfree --enable-decklink I can do recordings on DeckLink Duo (1) and DeckLink Duo (2) without any problems.

I've also tried running it with -duplex_mode half -video_input sdi however that doesn't seem to do it either. I have been able to set the card to half duplex in the past using windows, however, i don't want to use windows :) Does anyone have any idea of what might be going wrong? Thanks Rik

ffmpeg streaming to YouTube works better in Windows 10 than in Windows 7
by lifepdx＠gmail.com 06 Aug '19

06 Aug '19

Hello. I tried to stream video from an IP camera to YouTube and found a strange performance difference between Windows 10 and Windows 7. The command line is same in both cases ffmpeg -i test.mkv -c:v copy -c:a copy -f flv rtmp:// a.rtmp.youtube.com/live2/my-youtube-api-key (Data in MKV is unchanged video stream from camera + encoded aac sound ) I made test.mkv with following command: ffmpeg -loglevel debug -f lavfi -i anullsrc -rtsp_transport tcp -i rtsp:// login:password@1.2.3.4/media/video1/video -c:v copy -c:a aac test.mkv In Windows 7 speed is usually around 0.5x and fps are respectively low , around 12-13 (original video stream has 25 fps) also I have image corruption. In Windows 10 speed is around 1x / 25fps while streaming live video from camera and 3x when I stream mkv file. No problems with quality. tried ffmpeg-latest and ffmpeg 3.2 static builds, the same result. Windows 7 and Windows 10 installed on the same machine: AMD Phenom CPU 9650 + 4GB Ram Link to test.mkv : https://www.dropbox.com/s/6o6peadsj7gfn4e/test.mkv?dl=0 I would really appreciate if someone help me to understand what is happening ;) Thanks in advance!

Problem configuring ffmpeg
by Mahmood Naderan 06 Aug '19

06 Aug '19

Hi When I configure ffmpeg with the following command $ ./configure --enable-cuda --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp --extra-cflags=-I/usr/local/cuda/include,../nv-codec-headers/include --extra-ldflags=-L/usr/local/cuda/lib64 I get this error ERROR: libnpp not found As I search apt I see $ sudo apt install libnpp libnppc9.1 libnppicc9.1 libnppidei9.1 libnppig9.1 libnppist9.1 libnppitc9.1 libnppial9.1 libnppicom9.1 libnppif9.1 libnppim9.1 libnppisu9.1 libnpps9.1 By installing even all packages, I still get the same error. Any idea to fix that? Regards, Mahmood

receive udp audio stream
by Mustafa Al Ani 06 Aug '19

06 Aug '19

Hi, I'm trying to receive an audio only transport stream but can't figure out the right command. source : udp://@192.168.122.10:6006 Audio PID: 800 Service ID: 1001 I have tried different commands but none seems to be correct. Also read the stream specifier documentation as suggested in some articles but couldn't find how. Can anyone help? Regards, Mustafa
