Is it correct that the "displace" filter allows only displacements in the [-128 ... +127] range? Michael

Strange TC on 50 FPS clips
by Bouke / VideoToolShed 03 Feb '20

03 Feb '20

Hi all, Getting strange TC readings on 50 FPS clips. FFmpeg reports timecode : 11:26:32:42 (And that corresponds with the frame counter in the start of the mdat atom.) Premiere reports 22:53:05:34 QT 7 and Avid (older version) 22:53:05:17 Now Avid and QT have the habit of stepping trough the video by two frames if fps > 30, so that might be a hint. (If I take FFmpegs TC to frames, (2059642) multiply that by 2 I’m at the ‘correct’ frame number, converted back to TC it gives 22:53:05:34) Now, is this a bug or am I missing something? (Setting TC with FFmpeg has no issues as far as I’ve seen.) If interested, the clip can be found here: Download link https://we.tl/t-CP6GlfQIeG <https://we.tl/t-CP6GlfQIeG> (Turn your volume down if you want to play it, it has loud LTC on the right channel.)

Loss in frames while cutting video with -ss parameter
by Gracias, Hansel 03 Feb '20

03 Feb '20

Dear Team, I have a 15 min video file from which I want to extract a part starting from fifth second and end to 10 mins 5 secs. I used the below command:- ffmpeg -i start.wma -ss 00:00:05 -t 00:10:00 -c copy VideoClip.wma The issue is :- There is a loss of initial 5-8 seconds frames and I get video directly jumping to 00:00:10 instead of 00:00:05. However reencoding the video works fine but takes too much time. Please provide the solution to tackle with this without reencoding. With best regards, Hansel Gracias Siemens Ltd.

Problem with combining a video and an audio stream from USB device
by FHoevi 02 Feb '20

02 Feb '20

Dear all, I hope you could provide a hint to my problem: I have two USB devices attached to an RPi, both show up as usual as /dev/video0. Here's some additional info coming from two command line inputs: Device 1, video only (attached to an RPi4): "ffmpeg -f v4l2 -list_formats all -i /dev/video0" reports [video4linux2,v4l2 @ 0xe5e1c0] Compressed: mjpeg : Motion-JPEG : 1280x720 640x480 320x240 "v4l2-ctl --list-formats-ext" reports ioctl: VIDIOC_ENUM_FMT Type: Video Capture [0]: 'MJPG' (Motion-JPEG, compressed) Size: Discrete 1280x720 Interval: Stepwise 0.033s - 0.033s with step 0.000s (30.000-30.000 fps) Size: Discrete 640x480 Interval: Stepwise 0.033s - 0.033s with step 0.000s (30.000-30.000 fps) Size: Discrete 320x240 Interval: Stepwise 0.033s - 0.033s with step 0.000s (30.000-30.000 fps) Does work: ffmpeg -f v4l2 -i /dev/video0 -vcodec h264_omx -preset ultrafast -tune zerolatency -g 300 -b:v 1M -mpegts_service_type advanced_codec_digital_hdtv -f mpegts udp://OtherMachine:Port?pkt_size=1316 Device 2, video and audio (attached to an RPi3, but does not work either on the RPi4): "ffmpeg -f v4l2 -list_formats all -i /dev/video0" reports [video4linux2,v4l2 @ 0x2c41210] Compressed: mjpeg : Motion-JPEG : 1920x1080 1280x720 "v4l2-ctl --list-formats-ext" reports ioctl: VIDIOC_ENUM_FMT Index : 0 Type : Video Capture Pixel Format: 'MJPG' (compressed) Name : Motion-JPEG Size: Discrete 1920x1080 Interval: Discrete 0.033s (30.000 fps) Interval: Discrete 0.067s (15.000 fps) Size: Discrete 1280x720 Interval: Discrete 0.033s (30.000 fps) Interval: Discrete 0.067s (15.000 fps) After quite some tedious work and way too many hours I got this running: Video only: ffmpeg -f v4l2 -input_format mjpeg -i /dev/video0 -c:v copy -preset ultrafast -tune zerolatency -g 300 -f matroska udp://OtherMachine:Port?pkt_size=1316 Does not work at all: ffmpeg -f v4l2 -input_format mjpeg -i /dev/video0 -c:v copy -preset ultrafast -tune zerolatency -g 300 -f mpegts udp://OtherMachine:Port?pkt_size=1316, on "OtherMachine" I do see that there is an incoming data stream via VLC, but it could not be digested properly.

Both of them come from the same hardware/device, my guess is that the MJPG video stream is somehow not fully compliant with the mpegts standard (like it is for device 1) since it works with matroska, but not with mpegts. Could that be? What needs to be done in that case? Thanks in advance and kind regards FHoevi

sendcmd and overlay

I want to use sendcmd to set the x,y coordinates of the overlay filter. If I write sendcmd before overlay, I get this error message: Too many inputs specified for the "sendcmd" filter. But the two inputs are required for the overlay filter. How can this problem be solved? Console output is below.

kmsgrab on non primary card, libva/hwmap advice?
by test 02 Feb '20

02 Feb '20

Hi All. Thanks in advance for any assistance provided. I've been trying to get kmsgrab to work on my second rx570. Aim is to record multiple framebuffers on both cards. Both cards are maxed in terms of CRTC's, so switching all to one card isn't an option. x11grab has not been performant enough. I have three "cards": /dev/dri/card0 -> intel iGPU /dev/dri/card1 -> rx 570 /dev/dri/card2 -> rx 570 I have card1 working fine, it's the primary card. I haven't tried card0. /home/test/.local/bin/ffmpeg -framerate 60 -device /dev/dri/card1 -f kmsgrab -i - -vf 'hwmap=derive_device=vaapi,hwdownload,format=bgr0' /home/test/card1.mp4 Whilst trying for card2 and a similar command I get errors. I've tried advice under https://trac.ffmpeg.org/wiki/Hardware/VAAPI regarding device selection. The error doesn't change? ./ffmpeg -init_hw_device vaapi=foo:/dev/dri/by-path/pci-0000\:02\:00.0-render -filter_hw_device foo -framerate 60 -device /dev/dri/card2 -f kmsgrab -i - -vf 'hwmap= derive_device=vaapi,hwdownload,format=bgr0' /home/test/card2.mp4 Any advice would be appreciated. Cheers.

beginning, does not start until 0.566 for frame # 0 because (I think) the source video has an audio offset. This makes problem#1 affect all future edits. 2. overlay:between appears at frame# 446 15.433 sec which is not as requested at 511 a difference of 65 frames early. 3. overlay:between disappears early also, last frame# 1092 37.000 which is not 1224. A difference of 132 frames. My math on the drift makes that a factor of 90.6%, but [0] is 30 fps. The cause is because the gif file [1] is 30ms per frame, not 33.333ms, which accounts for the 90% figure. So question#2 is: How can I override the timing, and just copy frame by frame ignoring the timestamps of [1]? Problem #3: 4. overlay appears a second time for one frame at frame# 1207 40.799 sec Acts like it ignored it's own timestamp calculations and included one frame at the end of the requested range, plus the audio offset.
