0366664ef9 lavc: check channel count after decoder init 
Ensures the decoder did not set channel count to an insanely high value
during initialization, which could cause large memory usage when it tries to
get a buffer during decoding.

1bc64c2814 lavc: initialize output AVFrame before decoding. 
Avoids memleaks with audio when extended_data is nontrivial and the user
doesn't reset the frame.
Shouldn't have any effect for video for now, but might be useful in the
future.

c854102da7 avcodec: handle AVERROR_EXPERIMENTAL 
Error out on init if a codec with CODEC_CAP_EXPERIMENTAL is requested
and strict_std_compliance is not FF_COMPLIANCE_EXPERIMENTAL.

Move the check from avconv to avcodec_open2() and return
AVERROR_EXPERIMENTAL accordingly.

before calling avcodec_get_frame_defaults().

f75f4194d1 Restructure av_log_missing_feature message 
Some invocations include a verb in the log message, others do not.  Yet
av_log_missing_feature expects callers to provide a verb.  Change the
function to include a verb instead and update the callers accordingly.
The result is a more natural function API and correct English in the
function invocations.

to basically all PCM codecs and a small subset of ADPCM codecs.
