Due to some adds off AVExport for simplify build of the binding, remove some exports to reduce API.

Need a patch in FFmpeg.

If OpenGL (devel) was not found, build without the avplay target.

Due to codec latencies, some streams requires to process last frames after the end of the process.

FFmpeg exposes bit rate mode (CBR or VBR) in AVCodecContext structure.
http://ffmpeg.org/doxygen/trunk/structAVCodecContext.html#a65f37abbfc9d4630aa7fd44b9a1ebb21
We can expose that in our FileProperties.
Documentation about CBR / VBR: https://trac.ffmpeg.org/wiki/Encode/AAC

Several needs at mikros image: concatenation of several video.

We have the (versioned) lib for the python binding, but the python file doesn't exist.

This is not manage by the Transcoder.
All StreamTranscoder have the possibility to switch to dummy. The Transcoder needs to set the politic to each StreamTranscoder.

When we want to generate a stream (black or silence), we should not have to set both output profile and ICodec. The ICodec should be guessed from the profile, which must contain enough parameters to generate the stream.
It would avoid duplicated parameters into ICodec and profile.

https://github.com/mikrosimage/avTranscoder/blob/develop/src/AvTranscoder/transcoder/Transcoder.hpp#L56
https://github.com/mikrosimage/avTranscoder/blob/develop/src/AvTranscoder/transcoder/Transcoder.hpp#L66

For example can up from 8kHz to 48KHz, and down from 48Khz to 44,1KHz.

For video stream, when switch to a black image after rewrap/transcode, artefact can appear to the output image.

• transcoding yuv420p works (without essence transform)
• encoding with essence transform provide seg fault in avcodec_encode_video2 (see OutputVideo::encodeFrame

They should contain an AVCodecContext.
And next use avcodec_copy_context [http://ffmpeg.org/doxygen/trunk/group__lavc__core.html#ga3933b21b9dcb9173df3e56673b7a7d76] to set the encoder

This create empty thumbnail. The problem occur when i use 0 value with the method InputFile.seekAtTime

Not the right length in case of different fps betwwen the input stream and the output stream.
The totalDuration is for the input: need it for the output ( depends on the fps of the output ).
see ProgressListener::progress

There is a problem with the InputFile.analyse method when level parameter equals eAnalyseLevelFirstGop (the default value when no parameter is specified) : several threads are created and are not killed.

For example, in our application, metadatas extraction of 5 medias create 20 ghost threads

In CMake files, some options are setted using platform detection, but for compilers options.

Refers to:
https://github.com/avTranscoder/avTranscoder/blob/master/CMakeLists.txt#L20

• There is only one enum for threds option: "auto", which corresponds to value 0.
• The default value of threds option is 1. How to manage this ? New Type in Option of AvTranscoder ?

Maybe due to a different fps between input and output ?

Need to check the FHS [http://www.pathname.com/fhs/] to know were we can deploy the Jar file like we do.

Need to find out how to manage non 8bits images (get pix_fmt from AVCodecContext).
https://github.com/FFmpeg/FFmpeg/blob/master/ffmpeg.c#L1185
https://github.com/FFmpeg/FFmpeg/blob/master/ffmpeg.c#L1210

• prefix interface classes with I (example: InputStream -> IInputStream)
• folders and filenames without classes in lowerCamelCase
• Metadatas -> mediaProperties
• New folder option
• New folder swig

Currently this is not the case!
