Anton Khirnov 9929b3564c pthread_frame: simplify the code by using new AVPacket API
This also handles side data properly.

Anton Khirnov cdf58f0599 avpacket: fix copying side data in av_packet_copy_props()
Side data count is incremented by by calling av_packet_new_side_data()
in the following loop, setting it explicitly results in the resulting
value being twice what it should be.

Anton Khirnov 0ba5299a80 movenc: use the "encoder" metadata tag to write stsd Compressorname
This mirrors the demuxer behaviour and avoids accessing
AVCodecContext.codec, which should not be done in muxers.

Anton Khirnov c3311d472a avienc: sanitize variable naming in write_header()

Anton Khirnov b513bf6f69 yuv4mpegdec: do not set coded_frame properties

2014-05-18 10:19:35 +02:00
Anton Khirnov fd056029f4 lavc: add avcodec_free_context().
Right now, the caller has to manually manage some allocated
AVCodecContext fields, like extradata or subtitle_header. This is
fragile and prone to leaks, especially if we want to add more such
fields in the future.

The only reason for this behaviour is so that the AVStream codec context
can be reused for decoding. Such reuse is discouraged anyway, so this
commit is the first step to deprecating it.

Anton Khirnov e1b66778b6 lavc: remove the locking code in avcodec_close()

Anton Khirnov c9281a01b7 lavf: drop the zero-sized packets hack
There should not be any valid reason anymore for passing completely

OTOH side data-only packets can be useful.
2014-05-15 07:50:47 +02:00
Anton Khirnov 0c1959b056 lavf: add AVFMT_FLAG_BITEXACT.
Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's
codec context.

Using codec options inside lavf is fragile and can easily break when the
muxing codec context is not the encoding context.

Anton Khirnov 6072184e70 asfenc: use codec descriptors instead of AVCodecs to write codec info

deprecated.

Changes the result of the lavf-asf test (and its associated seektest),
since 'msmpeg4v3' gets written instead of just 'msmpeg4'.
