Can not read mjpeg from IP camera

[qqqzhouhk]

Summary of the bug: I downloaded a FFmpeg demo from the internet. Tried to change the video source to IP camera, but it shows bugs as follows. BTW I use OC in Xcode
How to reproduce:

self.video =[[XYQMovieObject alloc] initWithVideo:@"http://192.168.10.123:7060"];

The bug shows that

Input #0, mpjpeg, from 'http://192.168.10.123:7060':
  Duration: N/A, bitrate: N/A
    Stream #0:0: Video: mjpeg, yuvj422p(pc, bt470bg/unknown/unknown), 640x480, 25 tbr, 25 tbn, 25 tbc
[mpjpeg @ 0x7feadc818000] Expected boundary '--' not found, instead found a line of 8 bytes
[mpjpeg @ 0x7feadc818000] Expected boundary '--' not found, instead found a line of 2 bytes

I don't know what to do to fix it. It works when I use other internet source of video like

self.video = [[XYQMovieObject alloc] initWithVideo:@"http://live.hkstv.hk.lxdns.com/live/hks/playlist.m3u8"]; 

Can any one tell me what to do to debug that? I would really appreciate that. Thanks guys.

Does it work with the ffmpeg executable?

Please try to dump the stream into a file with something like wget http://192.168.10.123:7060 and upload the resulting file.

Does it work with the ffmpeg executable?

Sorry, what do you mean by ffmpeg executable? The demo code is working when the video source is from internet live stream, but it does not when changes to my IP camera, which uses HTTP protocol.

Please try to dump the stream into a file with something like wget http://192.168.10.123:7060 and upload the resulting file.

How to dump the stream into a file? The demo code can be downloaded from below:https://github.com/xiayuanquan/FFmpegDemo
Can you please be more specific? Since I am new to program. Thank you very much!!

Sorry, what do you mean by ffmpeg executable?

Does the following command line work?

$ ffmpeg -i http://192.168.10.123:7060 -qscale 2 -vcodec mpeg4 out.mov

Please try to dump the stream into a file with something like wget http://192.168.10.123:7060 and upload the resulting file.

How to dump the stream into a file?

Please try the following command line to dump the http stream into a file:

$ wget http://192.168.10.123:7060

An alternative is the following:

$ curl -o stream http://192.168.10.123:7060

I have tried what you told me to do, and here is the screenshoot of them:

$ ffmpeg -i http://192.168.10.123:7060 -qscale 2 -vcodec mpeg4 out.mov
-bash: ffmpeg: command not found
$ wget http://192.168.10.123:7060
-bash: wget: command not found

You need to have a ffmpeg binary to run ffmpeg. So far you haven't provided any method for us to duplicate the issue, and we have no idea how FFmpeg is involved here. Are you using the FFmpeg libraries, or are you somehow using the ffmpeg cli tool (although if you are it appears not to be in your PATH)?

I'm assuming you're using the libraries because you mentioned something called "FFmpegDemo", but we do not support third-party tools. Testing with a recent ffmpeg binary will more easily show if the issue is valid here.

You have to eventually stop the command. Because we do not have access to your input, creating a sample file can possibly be used as an alternative input to attempt to duplicate the alleged issue.

From a user's perspective, this is a regression since 6dc1d5f87ced885d748f8d0c7bfbc5ff6471483f

Sorry, I am still confused about what is the problem and how can I fix it? If it possible, could you please give me more hints or explain it in details, I would really appreciate it. Thank you again!

[Carl Eugen Hoyos]

Work-around is to specify -f mjpeg.

Man, you are awesome!! It works, but how can I achieve it when I am using FFMPEG library, as in FFMPEGdemo code? Thank you again, my bro!

I cannot use the -f mjpeg workaround because I'm using ffmpeg through openCV where there is no option to pass this parameter.

Any ideas?
