Cannot merge VisualSampleEntry error while appending videos in MP4parser
13 août 2021, par Abhishek IppakayalI am creating four videos with ffmpeg and then i am appending them with MP4parser.
Details of four videos that i am creating with ffmpeg.


- 

- 1,2 video : created using one image




[-loop, 1, -i, Count_1627453922.jpg, -s, 720x1280, -vf, format=yuv420p,fps=25,fade=type=in:duration=1,fade=type=out:duration=1:start_time=1, -t, 2, -preset, ultrafast, CountImageVideo_1627453922.mp4]


- 

- 3,4 video : trimming 3 second video from an existing mp4 video




[-i, footages_5_1624263519549.mp4, -ss, 00:00:00, -to, 00:00:02, -s, 720x1280, -r, 25, -preset, ultrafast, One_1627453926.mp4]


Now i am trying to append all these videos with MP4Parser and getting below error :


java.io.IOException: Cannot merge VisualSampleEntry[com.googlecode.mp4parser.boxes.mp4.ESDescriptorBox@f3f76444] and VisualSampleEntry[com.googlecode.mp4parser.boxes.mp4.ESDescriptorBox@e20a2ed0]
 at com.googlecode.mp4parser.authoring.tracks.AppendTrack.mergeStsds(AppendTrack.java:116)
 at com.googlecode.mp4parser.authoring.tracks.AppendTrack.<init>(AppendTrack.java:59)
</init>

I have done some debugging and found something that can help understand error better.
Sample Description boxes of two videos


Two video tracks have different formats (MP4v & AVC1). I am new to ffmpeg and MP4parser so did not getting what i am doing wrong. Thanks ! in advance.

Receiving pixelated and laggy rtsp stream on vlc when
7 août 2021, par mohit krishnaI'm trying to live stream my webcam from raspi4 using ffmpeg as a rtsp stream .
The command i'm using to do so :


ffmpeg -f v4l2 -framerate 30 -video_size 640x480 -i /dev/video0 -c:v mpeg4 -pix_fmt yuv420p -f rtsp -rtsp_transport tcp rtsp://stream

when I receive the rtsp stream using opencv , I get the desired output :




When I try to receive the said stream using vlc , it's pixelated , gray and laggy :




Edit :

Here's the log :

Why can't I duplicate an MJPEG stream from a webcam to a V4L2 Loopback Device on Linux ?
17 août 2021, par Chris WhiteI'm trying to duplicate a USB webcam device V4L2 stream (/dev/video0) to a V4L2 Loopback Device (/dev/video99) at the highest resolution and framerate possible with the hardware available on a Raspberry Pi 4 running the latest Raspbian (also the minimum CPU load). I'm using FFMPEG version 7:4.1.6-1 deb10u1+rpt2 and v4l2loopback version 0.12.5.1.


The output from :

ffmpeg -f v4l2 -list_formats all -i /dev/video0gives me the following :

[video4linux2,v4l2 @ 0xc1e1c0] Compressed: mjpeg : Motion-JPEG : 1600x1200 3264x2448 2592x1944 2048x1536 1280x960 1024x768 800x600 640x480 320x240 1600x1200
[video4linux2,v4l2 @ 0xc1e1c0] Raw : yuyv422 : YUYV 4:2:2 : 1600x1200 3264x2448 2592x1944 2048x1536 1280x960 1024x768 800x600 640x480 320x240 1600x1200


3264x2448px is the native CCD resolution, and the image is being used for machine vision purposes, so I'd like to use this maximum resolution at the highest framerate I can. The reason for the loopback device is so that I can view/stream the videofeed (with GStreamer) and take high resolution PNG snapshots simultaneously, using the command
ffmpeg -f v4l2 -video_size 3264x2448 -i /dev/video99 -frames 1 capture.png -yFrom my understanding this means there is an MJPEG stream at this resolution and according to the commandv4l2-ctl -d /dev/video0 --list-formats-extI can manage 15fps :

I feel like I've tried every possible version of GStreamer/FFMPEG command to achieve this and have had varying success, but more often than not I come up against "av_interleaved_write_frame() : Cannot allocate memory" or some issue with converting M-JPEG to rawvideo for the loopback device...


What command should I be using ? I'm at the end of my tether !


I've tried :


gst-launch-1.0 v4l2src device=/dev/video0 ! "image/jpeg,width=3264,height=2448,framerate=15/1" ! avdec_mjpeg ! "video/x-raw,format=YUY2,width=3264,height=2448,framerate=15/1" ! v4l2sink device=/dev/video99


and


ffmpeg -f v4l2 -video_size 3264x2448 -i /dev/video0 -vcodec rawvideo -pix_fmt yuyv422 -r 1 -f v4l2 /dev/video99
