Stefano Sabatini	d72c742d47	examples/muxing: factorize write_interleave code Also log output packet information.	11 years ago
Stefano Sabatini	5e2b8e4934	examples: add remuxing example Show how to perform streamcopy from one container to another.	11 years ago
Stefano Sabatini	d497141b85	examples/muxing: simplify video PTS setting Rely on frame_count. Also more consistent with audio path.	11 years ago
Andre Anjos	23ffc4c70d	doc/examples/muxing: Fixes frame initialization. Fixes use of the example with encoders which use tha AVFrame w/h/pix_fmt fields FFV1 is one of these codecs We cannot easily workaround the not set fields in common code because the API has AVFrame constant for the encoders. Alternatives would be to fix the API or to duplicate the struct and fill in missing fields. Or as is to require all user apps to set this correctly and maybe simplify for that case Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Stefano Sabatini	094c500caf	examples/muxing: set timestamps in output audio packet In particular, fix trac ticket #3231.	11 years ago
Stefano Sabatini	8d22d37e54	examples/muxing: use av_frame_free() in place of av_free()	11 years ago
Stefano Sabatini	9abe4a10fd	examples/muxing: reuse global audio frame Simplify logic, avoid multiple unnecessary alloc/free operations.	11 years ago
Stefano Sabatini	80bca6eabe	examples/muxing: honour distinction between encoder PTS timebase and stream timebase Fix PTS set on the frame when encoding, which must be specified in the encoder timebase or this will confuse the encoder. When muxing the packet, the PTS/DTS generated by the encoder is then rescaled to the stream timebase.	11 years ago
Stefano Sabatini	eadc421259	examples/muxing: set sample formats from list of codec supported sample formats Avoid the need of tweaking, also show how to get list of supported sample formats.	11 years ago
Stefano Sabatini	2503928a2f	examples/decoding_encoding: fix style nits	11 years ago
Ilya Basin	d1b8e01ef1	examples/muxing: fix memleaks in resampler - do not allocate resample dst buffer when resample is off - free sample buffers in addition to freeing data pointer arrays Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ilya Basin	7d1d0b3ecf	examples/muxing: use S16 sample_fmt for resample src regardless of codec sample_fmt We generate S16 samples and we should allocate the right buffer Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ilya Basin	b6714fa077	examples/muxing: fix av_frame_free() not called when got_packet is false Hi list! Since my last patch (fix 2 memleaks in doc/examples/muxing.c) I found more problems to fix. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Clément Bœsch	b02d87936b	examples/demuxing_decoding: print the decoding error when it happens.	11 years ago
Even Wiik Thomassen	43f116d162	examples/demuxing_decoding: return error when no codec found The open_codec_context function, when it fails to find a codec, now return AVERROR(EINVAL) to signal an error. Before it would return the stream index, which was always >= 0, and continue as if a codec was found. This change make it fail faster, instead of repeated failed tries to decode frames with no codec.

wm4	72f5a6d067	examples: demuxing: print ffplay command even if sample format is planar Adjust the code so that a working ffplay command is printed in the planar audio case.	11 years ago
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.	11 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.	11 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
