Description
Summary of the bug:
When streaming some Mjpeg sources ffmpeg (ffplay) may read an EOF as end of stream, when actually it's just the end of a frame.
When playing a stream in ffplay, it will play for some time (a minute or so) then the video will stop but ffplay goes on even though the video has stopped.
How to reproduce:
Run the following command, it will play the stream.
fplay -f mjpeg -i http://204.239.12.142/mjpg/video.mjpg ffplay version 2.7.1 Copyright (c) 2003-2015 the FFmpeg developers built with Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn) configuration: --prefix=/usr/local/Cellar/ffmpeg/2.7.1 --enable-shared --enable-pthreads --enable-gpl --enable-version3 --enable-hardcoded-tables --enable-avresample --cc=clang --host-cflags= --host-ldflags= --enable-libx264 --enable-libmp3lame --enable-libvo-aacenc --enable-libxvid --enable-ffplay --enable-vda libavutil 54. 27.100 / 54. 27.100 libavcodec 56. 41.100 / 56. 41.100 libavformat 56. 36.100 / 56. 36.100 libavdevice 56. 4.100 / 56. 4.100 libavfilter 5. 16.101 / 5. 16.101 libavresample 2. 1. 0 / 2. 1. 0 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 2.100 / 1. 2.100 libpostproc 53. 3.100 / 53. 3.100 Input #0, mjpeg, from 'http://204.239.12.142/mjpg/video.mjpg':0/0 Duration: N/A, bitrate: N/A Stream #0:0: Video: mjpeg, yuvj422p(pc, bt470bg/unknown/unknown), 480x360, 25 tbr, 1200k tbn, 25 tbc
After ~150 seconds, ffplay will continue, but the video output will stop.
I can reproduce it with the above stream every time.

Ran against the latest git head. VLC does stop too. But that closes the video as the stream closes.
ffplay seems to continue counting in the console (like there is an output), but the video just remains on the last frame.
I guess on the last frame it should close the output and terminate?

Replying to chrisjenx:

No, but you can use -autoexit
if you need this behaviour.
ffplay -f mjpeg -i http://204.239.12.142/mjpg/video.mjpg
Note that -f mjpeg
is not necessary.
Please test current FFmpeg git head except if you want to report a regression.
I ran several tests and the connection always stopped after exactly five minutes (with different applications). Is there an application that plays this stream for longer than five minutes?
