* ZoneMinder compiles with ffmpeg 0.5..master
* Make VideoStream class able to stream through ffmpeg better.
* Ability to use fixed quality instead of fixed bitrate (by specifying bitrate 0...100)
* Format url parameter supports <format>/<encoder> syntax
Details:
- Redefine av_err2str to a to avoid compiler warning on newer g++'s
- When using rtp format; if ffmpeg does not have a default codec, use CODEC_ID_MPEG4. (because this is what the default is as of 2.2 when this code was written)
- Specify ofc->packet_size if rtp format is requested
- Video generated in a thread to guarantee a constant fps.
- Move _AVCODECID definition into zm_ffmpeg.h (and use instead of (AV)CodecID
- Call avformat_network_init because ffmpeg warns about it beeing required soon.
- increase VideoStream::video_outbuf_size to 4MiB to be able to encode larger pictures
