When using "-f x11grab -i :0.0" valgrind reports a definitely lost
memory block with this message:
==31544== 5 bytes in 1 blocks are definitely lost in loss record 1 of 2

The 5 bytes lost are the ones from param = av_strdup(":0.0"), so let's
free param in the exit path.
Also check the av_strdup() return value.
Note: calling av_free(param) even when av_strdup() fails and param is
NULL is OK and keeps the code simpler without adding another label to
skip av_free().

Remove some unneeded memsets.
|
|
Instead of busy waiting use poll();
|
|
Let pass the codec name to -pixel_format and introduce -input_format.

V4L2_FMT_FLAG_EMULATED was added in 2.6.32.

Make use of the experimental framesize enumeration ioctl if available.
|
|
Unbreak direct streamcopy.
|
|
Check capabilities directly in the function, further simplify the code.
|
|
Only mmap is supported.

Video4linux2 supports both interlaced and non-interlaced mode, do not
ask for interlaced if not necessary.

It's supposed to be called only from (de)muxers.
|
|
It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.
Fixes a few invalid shifts.

The frame duration was calculated without taking in account the
bytes per sample.
Thanks to Lorenzo Pistone <blaffablaffa@gmail.com> for pointing
the issue and providing an initial fix.

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.

It currently use the simple api and is using the latency information
provided only to offset the stream start.

Trivial replacements with sed are done in this commit:

Fixes compile with next lavc major.

AVFormatParameters are converted into corresponding private options in
av_open_input_file/stream() compat wrappers, so accessing them from
demuxers is redundant.

Get rid of AVFormatParameters usage.

In testing, the file output plugin gave a max buffer size of about 20 million
frames, which is way more than what is really needed and causes a memory
allocation error on my system.
|
|
buffer_size/4 is the value used by aplay. This fixes output to null
devices, e.g. writing ALSA output to a file.
