2016-02-21ffserver&ffm: Fixed issues preventing ffserver write_index and files_size ↵Oliver Collyer
from being set correctly which was breaking ffserver streaming. I discovered that ffserver streaming was broken (it seems like it has been since 20th November) and I opened a ticket for this (https://trac.ffmpeg.org/ticket/5250 <https://trac.ffmpeg.org/ticket/5250>). I spent yesterday learning git bisect (with the kind help of cehoyos) to painstakingly track down the cause. This was made more difficult due to the presence of a segfault in ffserver during the period where the bug was introduced so I first had to identify when and how that was fixed and then retrospectively apply that fix again for each step of the second git bisect to find the actual bug. Anyway, the fruits of my labour are the innocent looking patch below to correct a couple of typos and define a valid range for two variables.

2016-01-12ffmdec: change type of len to ptrdiff_tAndreas Cadhalpun
It is used to store the difference between pointers, so ptrdiff_t is the correct type. This prevents potential overflows. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>

2015-12-16ffm: reject invalid codec_id and codec_typeAndreas Cadhalpun
A negative codec_id cannot be handled by the found_decoder API of AVStream->info: if the codec_id is not recognized, found_decoder is set to -codec_id, which has to be '<0' according to the API documentation. This can cause NULL pointer dereferencing in try_decode_frame. Also make sure the codec_type matches the expected one for codec_id.

2015-12-04ffmdec: reject zero-sized chunksAndreas Cadhalpun
If size is zero, avio_get_str fails, leaving the buffer uninitialized. This causes invalid reads in av_set_options_string. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>
