wm4	9f31c1608c	examples: demuxing: simplify audio output There is no reason why this should copy the audio data in a very complicated way. Also, strictly write the first plane, instead of writing the whole buffer. This is more helpful in context of the example. This way a user can clearly confirm that it works by playing the written data as raw audio.	12 years ago
wm4	06b269dacb	examples: demuxing: do partial audio packet decoding This assumes one audio packet is decoded one time. This is not true: packets can be partially decoded. Then you have to "adjust" the packet and pass the undecoded part of the packet to the decode function again.	12 years ago
Stefano Sabatini	2aa2b4ac65	examples/muxing: add support to audio resampling Allows to encode to output in case the destination sample format is different from AV_SAMPLE_FMT_S16.	12 years ago
Stefano Sabatini	838bd73139	lavfi: create Libav-API compatibility layer for avfilter_graph_parse() at the next bump Add function avfilter_graph_parse_ptr() and favor it in place of avfilter_graph_parse(), which will be restored with the old/Libav signature at the next bump. If HAVE_INCOMPATIBLE_LIBAV_API is enabled it will use the Libav-compatible signature for avfilter_graph_parse(). At the next major bump the current implementation of avfilter_graph_parse() should be dropped in favor of the Libav/old implementation. Should address trac ticket #2672.	12 years ago
Stefano Sabatini	759dfd5684	examples/muxing: make more compact audio/video_time computation	12 years ago
Stefano Sabatini	80b56a7bdd	examples/muxing: rename audio/video_pts to audio/video_time The new name is less confusing, since the variables represent times rather than timestamps.	12 years ago
Stefano Sabatini	c58d535b2f	examples/Makefile: disable -O2 optimizations There is no much point in optimizing example code, and the -O2 flag is annoying when debugging.	12 years ago
Stefano Sabatini	3aa57e1582	examples/muxing: remove useless instruction Simpler and less confusing.	12 years ago
Stefano Sabatini	4b6cf1ce0e	examples/muxing: vertically align	12 years ago
Nicolas George	300ca0763b	examples/filtering_audio: fix frame leak. The frame is not used after being added to the filter graph, there is no need to keep the reference.	12 years ago
Pavel Koshevoy	e5644313c5	examples/filtering_audio: get rid of AVABufferSinkParams AVABufferSinkParams are ignored by avfilter_graph_create_filter, therefore the example is misleading. Use av_opt_set_int_list to configure abuffersink directly. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Clément Bœsch	5e4bc96415	doc: fix examples.	12 years ago
Nicolas George	9b211c43dc	examples/muxing: fix memory leak. Do not re-call avcodec_get_context_defaults3(), it is already called by avformat_new_stream() and it leaks the codec priv_data that was already allocated. Use avformat_free_context() instead of freeing (not) everything manually. Fix trac ticket #2322.	12 years ago
Michael Niedermayer	5ade6bfb03	doc/examples/demuxing: use AVFrame accessor functions Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Nicolas George	dcc73aaaa9	doc/examples: do not allocate AVFrame directly. The size of the AVFrame structure is not part of the ABI; it can grow with later versions. Therefore, applications are not supposed to allocate AVFrame directly, they are supposed to use avcodec_alloc_frame() instead.	12 years ago
