Anton Khirnov 1afddbe59e avpacket: use AVBuffer to allow refcounting the packets. 
This will allow us to avoid copying the packets in many cases.

This breaks ABI.

Anton Khirnov 838b849e70 v4l2: set the average framerate instead of codec timebase. 
Codec timebase is supposed to be set by decoders only.

Anton Khirnov 246da0b135 v4l2: avoid pointless indirection. 
v4l2_read_header() does no cleanup, so it can return directly, without
any need for goto.

Anton Khirnov c3f9ebf743 lavf: make av_set_pts_info private. 
It's supposed to be called only from (de)muxers.

Reimar Döffinger bb3244dee2 Replace all usage of strcasecmp/strncasecmp 
All current usages of it are incompatible with localization.
For example strcasecmp("i", "I") != 0 is possible, but would
break many of the places where it is used.

Instead use our own implementations that always treat the data
as ASCII.

Diego Biurrun 30b4ee7901 Use explicit struct initializers for AVOutputFormat/AVInputFormat declarations. 2011-09-24 12:11:17 +02:00
Anton Khirnov c14fe6bc99 lavf,lavd: remove all usage of AVFormatParameters from demuxers. 
AVFormatParameters are converted into corresponding private options in
av_open_input_file/stream() compat wrappers, so accessing them from
demuxers is redundant.

Stefano Sabatini 41b68dce4d lavdev: improve feedback in case of invalid frame rate/size 
Show the invalid string in the error message.

While at it also prefer "Could not" over "Couldn't", plain forms are
preferred over contractions (simplify readability, especially for non
English-savvy people).

Stefano Sabatini e60068baeb v4l2: prefer "framerate_q" over "fps" in v4l2_set_parameters() 
The variable is used for containing the parsed value of framerate,
using a lexically consistent name eases readability/understanding.
