Description
Summary of the bug: Older version of ffmpeg can read mjpeg stream from a Mobotix IP camera without issues. The latest version from git cannot.
How to reproduce:
% ffmpeg -i 'http://192.168.100.233/cgi-bin/faststream.jpg?noaudio' -y test.mkv
In version: N-69470-g36adfa3 (2015-02-01 22:53:38) - this command records the stream without any issues.
In version: git-2015-11-18-518742b I see the following:

If I wget, it looks like standard mjpeg:
$ head -n 4 faststream.jpg\?noaudio --MOBOTIX_Fast_Serverpush^M Content-type: image/jpeg^M Content-length: 483524^M ^M
After the blank line is raw binary data for the jpeg image.
Here is output from the working old version:

Regression since 53e8bef25a78457e4339e353568004f03b8a2396 - may be related to ticket #4840.
comment:6 by , 9 years ago
I wouldn't call it a regression -- a far-end bug had been previously masked by a bug in demux selection.
Without seeing full HTTP response, I can only guess why this stream worked before, but it’s an invalid mpjpeg stream. The code (both original, and following the patch) requires each body part to be accompanied by Content-Type and Content-Length, and the attached dump shows Content-Length available on the first part, but not on the subsequent ones.
My best guess is this: prior to the patch, for a variety of reasons (all of which had been patched), mjpeg demux could be selected instead of mpjpeg (the old version logs confirm it is being the case). MJPEG demux is more tolerant — it pretty much looks for jpeg header, consumes the jpeg and generates logs noise for the following unconsumed data (such as multipart headers), until it finds next jpeg in the stream. After the patch, the stream uses mpjpeg demux, based on HTTP response's Content-Type and the first correct frame headers, but later on breaks due to missing Content-Length.

Isn't the issue that this isn't a mpjpeg stream and should not be detected as mpjpeg?
comment:8 by , 9 years ago
Current criteria for mpjpeg selection is:
1) Content-Type of multipart/x-mixed-replace. Without full HTTP headers we can't know for sure it's present, but I'll venture to guess it's there.
2) Being able to successfully parse first part of the multipart (parse_multipart_header in mpjpegdec.c -- requirement is Content-Type of image/jpeg and presence of Content-Length)
From what I see, this stream satisfies both upon probing, later on relapsing by removing Content-Length from 2nd MIME part on.
comment:9 by , 9 years ago
Are there any disadvantages to using the more (broken stream) tolerant mjpeg demux by default? - or maybe it's worth checking the first 2 frames?
This seems to be quite common in the video surveillance world, not just with Mobotix. For example ACTi and Panasonic also. FYI I am running the latest version of the firmware for this IP camera and I will report this issue to the multiple manufacturers but I am not holding my breath :(
comment:10 by , 9 years ago
The main disadvantage is that the remainder of the data (e.g. MIME headers) are being passed to the decoder resulting in avcodec_decode_video2 returning an error:
[ffmpeg's output] FFMPEG >> decode frame unused 68 bytes
[ffmpeg's output] FFMPEG >> No JPEG data found in image
[our output] Error decoding video - err=-1094995529 Invalid data found when processing input
The only way to make mjpeg demux work in this situation is to not check for errors from avcodec_decode_video2, or ignore those -- possible, but pretty dirty.
The best solution would be to keep mpjpeg demux, but remove the dependency on Content-Length (since it's technically not required by MIME), and do a proper multipart MIME parsing (skip the headers, consume the body until the next boundary). I could look at it, but likely not in the next week or two.

That makes very good sense!- it seems even using the old version can be temperamental with some of those cameras. It would be really fantastic to have this solution whenever you find some time to work on it :)
comment:12 by , 9 years ago
I've submitted a patch proposal earlier last week, with the latest iteration being here: http://ffmpeg.org/pipermail/ffmpeg-devel/2015-November/184196.html
Hoping it'll be approved and merged in sometime this week, but at this point you can at least try and let me know whether it works in your setup (it does with a few MJPEG cameras, I have access to - including Axis cameras and gateway, as well as your packet trace)
comment:13 by , 9 years ago
Added a sample of a wget of a stream that even older version of ffmpeg report an invalid stream for. Any ideas why that is? - Would be fantastic to have a solution whenever you find some spare time :)

Fixed by Alex Agranovsky in 79103f21990307bb8855a03d68154e1c5d197a7c
It was originally planned to keep this stream detected as mpjpeg but change the demuxer so it does not fail for this stream, it is now fixed through detection as mjpeg, if the mpjpeg demuxer is forced, it also works fine!

Thank you for looking into this! - Unfortunately I do not have access to this camera at present, I will test the fix when I do :)

Sorry, I did not have access to this camera until now. It seems the fix does not resolve the issue when opening over http.

Any ideas why the stream is not detected correctly when live? - Any solution?

Please confirm that this worked fine with 01770bfd and is broken since 53e8bef2

Replying to hackeron:
I am not able to get it working since N-69470-g36adfa3 (2015-02-01 22:53:38)
This is most unlikely the responsive commit: 36adfa32748f69bf09f49e8a0f424a79c19003fb
What did you test?
comment:20 by , 9 years ago
I tested:
- N-69470-g36adfa3 (2015-02-01 22:53:38) - works most of the time (but not 100%)
- git-2015-11-18-518742b - does not work at all
- git-2016-02-05-9556446 - works for a file source, but not for a live (http) source
What else would you like me to test?

As said: Please confirm that this worked fine with 01770bfd and is broken since 53e8bef2
comment:22 by , 9 years ago
How do I do that?
I tried googling for ffmpeg 01770bfd (no results), tried git reset --hard 01770bfd says fatal: ambiguous argument '01770bfd'. Also git log -g --grep=01770bfd returns nothing. Please advice.
EDIT: Ah, figured it out: https://api.github.com/repos/ffmpeg/ffmpeg/commits/01770bfd -- going to test now.

I tried a few versions and cannot get any of them to work reading directly from the camera.
I noticed that this workaround helps with ffmpeg:
curl 'http://admin:meinsm@192.168.100.233/cgi-bin/faststream.jpg?stream=full&fps=5.0&noaudio&data=v.mjpeg' 2>/dev/null | ffmpeg -i - -y test.mkv
So I'm not sure what is special about this web server and why ffmpeg struggles to read from it correctly. Here is the debug log reading directly:

Have you ran it with -f mjpeg?
As to the facts:
- this camera produces an mpjpeg stream
- this stream was previously detected as mjpeg, and that worked, albeit generating a ton of warnings (for the envelope multipart data)
- for some reason, ffmpeg, even with the most recent changes, doesn't like this mpjpeg stream (though, as I've personally and hackeron have tested, it's just fine with the wget's output)
- to resolve this I suggest either providing us with a packet capture (full tcpdump/wireshark output, containing both the request and the response), *or* making this camera available for us to test against

Hi there, indeed the point of the ticket is you can't specify "-f mjpeg" if you run from OpenCV for instance. I am opening the source like this: cv2.VideoCapture('http://192.168....')
I will try a packet capture as indeed the issue is seems to be with that camera's specific web server. If I put the file on my own nginx server, I am able to open without issues. For now I have switched to an older version of FFMPEG that does not experience this issue.

I'm looking at git bisect documentation and I don't know what to do. It says to run tests on each revision? - Please advice.
comment:35 by , 9 years ago
$ make distclean $ git bisect start $ git checkout 36adfa32 $ ./configure && make ffmpeg [now test to confirm it does work] $ git bisect good $ git checkout 53e8bef2 $ ./configure && make ffmpeg [now test to confirm it does not work] $ git bisect bad [here starts the loop] $ ./configure && make ffmpeg [test and pass either "good" or "bad" as option to the next command] $ git bisect good/bad [either it says "first bad revision is" or to back to "here starts the loop"]
This takes between fifteen and twenty minutes here.

Ah, fantastic, thank you for that! - The server is in Africa and is currently offline, I will do this as soon as it is back online, that is most helpful.

It looks like Mobotix provides a MIME boundary enclosed in quotes - http://developer.mobotix.com/docs/mxpeg_frame.html. Uncommon, but valid according to RFC 2046. Other people had ran into this before - https://code.google.com/archive/p/aforge/issues/157
Having a full packet capture (including HTTP request/response) will help in both confirming this, fixing and verifying the fix. Please provide a packet capture (refer to http://www.howtogeek.com/104278/how-to-use-wireshark-to-capture-filter-and-inspect-packets/, if unfamiliar with Wireshark).
comment:38 by , 9 years ago
Actually, just realized that by default we're not running a full match on the boundary, and just are looking for '--'. So it's still pretty important to have the packet capture in order to fully understand what's going on.

comment:40 by , 9 years ago
I've submitted 3 mpjpeg patches last night. 2 had been applied so far. This one (09b8e) isn't likely to fix things, since it is only effective for Mobotix when 'strict_mime_boundary' option is set, which isn't the default.
However, I would recommend testing once all three patches are applied, and if still broken, please provide a packet capture. Thanks!

Please run git bisect and tell us which commit originally introduced the issue.
comment:46 by , 8 years ago
It used to work intermittently because of the use of the deprecated "mjpeg demux" on 36adfa32748f69bf09f49e8a0f424a79c19003fb but was still unreliable and doesn't appear to be a viable solution.
The problem is reading from the camera's webserver and cannot be reproduced reading from my own web server serving the file (this affects all versions).
I've attached a TCP dump to try to help diagnose the source of the problem.
follow-up: 48 comment:47 by , 6 years ago
This is still an issue with the latest from git (d6b1248...), though with an Arecont Vision rather than Mobotix camera. The problem occurs in mpjpeg_read_packet() at the avio_seek() call when locating the boundary marker:
do { if (!memcmp(start, mpjpeg->searchstr, mpjpeg->searchstr_len)) { // got the boundary! rewind the stream avio_seek(s->pb, -len, SEEK_CUR); // Silently fails, does not affect stream state pkt->size -= len; return pkt->size; } len--; start++; } while (len >= mpjpeg->searchstr_len);
At the point when avio_seek() is called, there is not enough data in the buffer to seek back by the correct amount, so the call fails.
There is a call to ffio_ensure_seekback() which looks like it's meant to ensure that it is always possible to seek back by this amount, but from what I can tell this will work only at the beginning of the stream (i.e. for probing or headers) and not mid-stream. Is anyone able to confirm that?

Replying to smbz:

I ran across this issue thanks to this question on the ffmpeg-user mailing list, which also references a Mobotix camera:
http://ffmpeg.org/pipermail/ffmpeg-user/2019-May/044412.html
I found a public stream and could reproduce the behavior.
I did an independent analysis of the issue, and came to exactly the same conclusion: ffmpeg is overreading one of the frames, due to failure to seek back.
This can be confirmed by evaluating the avio_seek()
return value and adding a warning on failure. The warning will pop up right when ffmpeg terminates due to the parsing error.
There is a call to ffio_ensure_seekback() which looks like it's meant to ensure that it is always possible to seek back by this amount, but from what I can tell this will work only at the beginning of the stream (i.e. for probing or headers) and not mid-stream. Is anyone able to confirm that?
My take is that ffio_ensure_seekback(s->pb, read_chunk)
, where it's currently placed, only makes sure that the first chunk is rewindable. This needs to be done for every subsequent chunk fetch as well. I dropped (or rather moved) that line and instead changed the while condition:
while ((ret = ffio_ensure_seekback(s->pb, read_chunk - remaining) >= 0) && (ret = av_append_packet(s->pb, pkt, read_chunk - remaining)) >= 0) {
And suddenly, decoding the stream works perfectly (at least as far as I expect from any mpjpeg stream).
I can propose a patch to ffmpeg-devel, but if anyone wants to confirm and commit my fix before that, I'll happily take the credit. ;-)
