Description
Summary of the bug:
RTP encoding of Trendnet TV-IP651WI IP camera produces undecodable stream.
Tested same scenario with Axis M1034-W IP camera, works fine, however, Axis uses yuvj420p pixel format
Stream #0:0, 1, 1/1200000: Video: mjpeg, yuvj420p(pc, bt470bg), 320x240 [SAR 1:1 DAR 4:3], 1/25, 25 tbr, 1200k tbn, 25 tbc
, while Trendnet uses yuvj422p.
I can provide FFmpeg developers with URL to camera's HTTP MJPEG stream, and TCP dumps i already have, on demand. Please email me to andrey.utkin@corp.bluecherry.net
The original stream plays well with
ffplay -loglevel debug -f mjpeg http://user:password@host/mjpeg.cgi
Stream generation:
$ ffmpeg -f mjpeg -i 'http://user:password@host/mjpeg.cgi' -loglevel debug -vcodec copy -f rtp rtp://127.0.0.1:6666

Is network input required to reproduce your issue or is it also reproducible with file input?

Sorry for delay.
Made a dump.mkv file (https://dl.dropboxusercontent.com/u/43104344/dump.mkv), taken this way:
$ ffmpeg -loglevel debug -f mjpeg -use_wallclock_as_timestamps 1 -i 'http://user:password@host/mjpeg.cgi' -codec copy trendnet_rtp/dump.mkv ffmpeg version N-65153-gad99837 Copyright (c) 2000-2014 the FFmpeg developers built on Aug 1 2014 16:44:34 with gcc 4.7.3 (Gentoo 4.7.3-r1 p1.4, pie-0.5.5) configuration: --enable-libfreetype --enable-gpl --enable-libx264 --enable-openssl --enable-nonfree libavutil 52. 94.100 / 52. 94.100 libavcodec 55. 71.100 / 55. 71.100 libavformat 55. 50.100 / 55. 50.100 libavdevice 55. 13.102 / 55. 13.102 libavfilter 4. 11.102 / 4. 11.102 libswscale 2. 6.100 / 2. 6.100 libswresample 0. 19.100 / 0. 19.100 libpostproc 52. 3.100 / 52. 3.100
The issue is indeed reproduced if you stream RTP this way:
ffmpeg -re -i trendnet_rtp/dump.mkv -loglevel debug -vcodec copy -f rtp rtp://127.0.0.1:6666
comment:4 by , 10 years ago
Any updates?
Is that correct that yuv422p is not supported by FFmpeg's MJPEG RTP packetizing code?
comment:6 by , 9 years ago
Replying to thovo:
Could you re-upload your example file "dump.mkv"?
That file was removed from all storages, sorry. But there's a chance that camera owner will take a dump of the stream from it. I'll update the ticket if i get such a file.
comment:7 by , 9 years ago
I believe the issue is reproducible with the following commands:
$ ffplay rtp://127.0.0.1:5004
$ ffmpeg -f lavfi -i testsrc -vcodec mjpeg -f rtp -pix_fmt yuvj422p rtp://127.0.0.1:5004
Only yuvj420p is supported.
comment:8 by , 9 years ago
There is also a yuvj422p demo file here:
https://trac.ffmpeg.org/attachment/ticket/4317/samplevideo.mjpeg
I have a webcam that produces yuvj422p mjpeg streams. I can provide more yuvj422p mjpeg demo files to help enabling ffmpeg to at least play them back.

My command line from comment:7 cannot work because the FFmpeg mjpeg encoder's 4:2:2 output is not compatible with rfc 2435, I opened ticket #4709.
The samplevideo.mjpeg sample cannot be sent over rtp because it uses non-standard Huffman tables which the rfc also doesn't allow. A patch was just merged that prints an error now instead of silently sending an invalid stream. My guess is that dump.mkv had the same issue.
There is still an issue with quantisation tables (that I will try to fix) but it isn't easy to trigger because of above issues.

My guess was correct, this was sent:

And this is what the decoder on the receiving side sees:
[mjpeg @ 0x7f3810001960] marker=c4 avail_size_in_buf=15010 [mjpeg @ 0x7f3810001960] class=0 index=0 nb_codes=12 [mjpeg @ 0x7f3810001960] class=0 index=1 nb_codes=12 [mjpeg @ 0x7f3810001960] class=1 index=0 nb_codes=251 [mjpeg @ 0x7f3810001960] class=1 index=1 nb_codes=251
Thanks to the original debug output!

Should be fixed in 9901e5318730ad5f9fb3272aa370e7affe168ddb
I attached a sample that allows testing with jpeg 4:2:2.

With a build of b3f8d871eeda38991108db7151e6c396808b22fe (Oct 8 2015), I get "error RFC 2435 requires standard Huffman tables for jpeg" and no output on RTP encoding of yuv422p JPEG stream. The same stream is encoded with artifacts with a build of 7f64a7503b19b39f1251e4380987034c569bebf5 (Apr 11 2015).
@cehoyos, according to your last comment this is not intended behaviour, as you seem to strive to fix this case completely. Also RFC seem to allow custom Huffman tables, but I may be missing something...

I think cehoyos' kindness can be improved.
Is your own 422.jpg attachment intended to fail RTP encoding? It is unclear from your comment. Actually, it fails.

When I attached it, I had not realized the need to provide standard huffman tables for jpeg-over-rtp and the check in FFmpeg had not existed yet. The existing check is too strict and has to be improved.

Could you please point what has to be improved and where in code?
Or would you consider to fix this soon for a donation? YUV422P became quite common for MJPEG streaming, so it is important (for our use case) to support it. You can find a load of YUV422P MJPEG streams here: http://www.mjpeg.net/

Working on a patch to support large JPEGs over RTP: https://github.com/bluecherrydvr/ffmpeg/commit/0f15de1bb10d8afa6c0fcbaa5eb1368e731a7b70
This patch needs to be applied to test the source in orig.mkv.
So, when it is used this way:
ffmpeg -re -i /tmp/orig.mkv -c copy -f rtp rtp://127.0.0.1:7777 -loglevel debug | tee /tmp/sdp
with
ffplay -i /tmp/sdp
The encoding side shows no errors, but ffplay gives decoding errors:

When I try synthetic yuvj422p source with ffmpeg -f lavfi -i testsrc,format=pix_fmts=yuvj422p -c mjpeg -f rtp rtp://127.0.0.1:7777 -loglevel debug it says Only 1x1 chroma blocks are supported. Debugger shows the checked scaling factor values are 0x18 for Cb and Cr components in this case, and they are 0x17 here when ffmpeg does rtp encoding from ready mjpeg stream in above case, despite these bytes are 0x11 in original file. I find this strange and I mention this detail just for your information.
Is rtp encoding of yuvj422p MJPEG supposed to fail here? Or is it related not to "pixel format", but to another property of stream?

Understood the point of comment:9, but could you give at last a bare idea what is wrong with orig.mkv case? Is it supposed to be failing at RTP encoding (but doesn't), or the decoder is wrong?
Of course I will submit my patch for review.
