VHS 捕获设备

VHS 捕获设备

我有一个 VHS 捕获设备 ecap303,来自 climaxdigital,在 Windows 7 上使用,我是 ubuntu 新手,但已使用命令 lsusb 连接设备并出现

ID EBIA : 2861 EMPIA TECH INS

我知道这个设备的驱动程序已写入 ubuntu 12.10,但我需要什么软件才能使用该设备复制 vhs 磁带并制作 dvd 副本,例如我可以使用 mplayer 或 vlc media player 吗

我希望你能帮助或建议一个更好的捕获设备

我试过 tvtime,可以从 vcr 和 freesat 机顶盒观看视频,但尽管尝试了回复中推荐的步骤,还是听不到声音,您还能提出其他建议吗

我按照建议尝试过,但仍然收到上面复制的错误消息,但当然没有提到我的内部网络摄像头,但仍然没有声音,我想知道我的捕获设备是否可以与 ubuntu 一起使用

答案1

正如我在对这个问题的评论中提到的那样,这个答案将根据@malcolmelliot的结果进行修改,以便为他的问题提供正确的支持。 (抱歉,评论太有限了。

步骤 1——查找视频设备。

好的,首先我们需要确保 tvtime 使用正确的设备来收集音频和视频。请记住,您可以拥有 2 个或更多视频设备,其中一些不会嵌入音频(如网络摄像头),而有些会。

您收到一条错误消息,其中包含以下部分文本:

Your capture card driver: uvcvideo [Integrated_Webcam_1.3M/usb-0000:00:1d.7-2/197895]
does not support full size studio-quality images required by tvtime.
This is true for many low-quality webcams.  Please select a
different video device for tvtime to use with the command line
option --device.

请注意,错误消息清楚地指向您的“Integrated_Webcam_1.3M/usb-0000:00:1d.7-2/197895”这确实是您计算机的网络摄像头。(也许是笔记本电脑嵌入式网络摄像头?基于 1.3M 数据)

因此,我们需要检查系统中有多少设备,以便对它们进行一些测试。为了了解此信息,我们将在终端中输入下一个命令:

ls -l /dev/video*

结果应该是这样的:

geppettvs@DYLAN:~$ ls -l /dev/video*
crw-rw----+ 1 root video 81, 0 2012-04-17 19:53 /dev/video0
crw-rw----+ 1 root video 81, 1 2012-04-17 19:53 /dev/video1
crw-rw----+ 1 root video 81, 2 2012-04-18 17:54 /dev/video2
geppettvs@DYLAN:~$ 

就我而言,我有 3 个视频设备,其中一个是 USB 电视调谐器,我用它来观看/录制直播电视节目/VTR/VCR/RF-DVD/视频转换器和其他 RF 信号。

您应该检查其中任何一个并记录结果以便继续。只需tvtime --device=/dev/video0在终端中通过运行测试即可。对tvtime --device=/dev/video1(这可能会导致错误,因为我们看到此设备是您的网络摄像头)和其他实例(如tvtime --device=/dev/video2tvtime --device=/dev/video3等)也执行此操作。

当您找到确切的 tvtuner 设备时,请确保使用它来执行下一个过程。

第 2 步 - 在同一个流中收集音频和视频。

现在,我们需要确保你能在同一流中收集音频和视频。如果你进入tvtime终端并获取视频但没有音频,那么我们需要指示声音系统获取音频并同时重现它。这可以通过在终端中输入以下命令来实现:

tvtime --device=/dev/videoX | arecord -D hw:1,0 -r 48000 -c 2 -f S16_LE | aplay -

请注意,您应该/dev/videoX用上一步中找到的适当设备进行替换。

这将使音频和视频同步并嵌入到同一个流中。如果是这样,那么我们可以继续捕获步骤。

如果成功,请告知以便继续。

祝你好运!
