[FFmpeg-user] bitrate=N/A at 640x480, no video recorded
Hi,
I'm trying to record a video at 640x480, but ffmpeg is not working as expected
in this case.
My command line:
ffmpeg -y -s 640x480 -t 00:00:20 -i /dev/video0 out.mpg
The output:
ffmpeg version 2.8.7 Copyright (c) 2000-2016 the FFmpeg developers

And then it just stays like this. I've checked with strace and the program is
stuck in a loop, trying to dequeue the video buffer
( it loops here: ioctl(3, VIDIOC_DQBUF, {type=V4L2_BUF_TYPE_VIDEO_CAPTURE}) =
-1 EAGAIN).
Ffmpeg works normally on lower resolutions, though. I've also tested the
camera, and it supports this resolution.
From what I understand, ffmpeg is not being able to get any data from the video
device, thus it can't encode the video. Why?
My system specs are: Kernel 3.2.61, 64 MB RAM, 128 MB Storage Space.
Regards,
---

[FFmpeg-user] RES: Memory usage growing when using ffmpeg. Is this expected?
Reindl, The issue is that the system was dedicated to recording the video. Usually the memory consumption baseline is around 8MB. Once there are other applications running, such a memory usage is troublesome. As I said, this is an _embedded_ system. I was presented with these restraints, and I need to evaluate if it is possible to record videos within such restraints.

[FFmpeg-user] Memory usage growing when using ffmpeg. Is this expected?
Hi, I am using ffmpeg record a video from a webcam, but the memory usage is very high, and keeps increasing with video length. For example, I use an embedded device with 64 MB of RAM, and when I recorded a 30 minute video, I was left with 2MB of RAM in the last minutes of the recording. I used valgrind to check for memory leaks, but I only found a 24 byte leak when the program finishes. Is this memory consumption expected for ffmpeg? This is the ffmpeg command I used: ffmpeg -f video4linux2 -s 320x240 -t 00:00:10 -i /dev/video0 out.mpg Regards, --- Guilherme de Oliveira Costa Firmware Engineer - Autotrac Comercio Telecomunicacoes www.autotrac.com.br<http://www.autotrac.com.br/> guilherme.oliveira(at)autotrac.com.br Phone: +55 61 3307 7000 (Extension 2665) Esta mensagem e qualquer anexo a ela s?o documentos confidenciais e direcionados exclusivamente ao(s) destinat?rio(s).
