* | examples/muxing: set timestamps in output audio packetStefano Sabatini2014-01-091-0/+7
| | | | | | | | In particular, fix trac ticket #3231.
* | examples/muxing: use av_frame_free() in place of av_free()Stefano Sabatini2014-01-091-1/+1
| |
* | examples/muxing: reuse global audio frameStefano Sabatini2014-01-091-7/+13
| | | | | | | | Simplify logic, avoid multiple unnecessary alloc/free operations.
* | examples/muxing: honour distinction between encoder PTS timebase and stream ↵Stefano Sabatini2014-01-091-1/+5
| | | | | | | | | | | | | | | | | | | | 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.
* | examples/muxing: set sample formats from list of codec supported sample formatsStefano Sabatini2014-01-091-1/+2
| | | | | | | | | | Avoid the need of tweaking, also show how to get list of supported sample formats.

* | examples/muxing: fix memleaks in resamplerIlya Basin2013-12-211-12/+18
| | | | | | | | | | | | | | - 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>

| | | | | | | | | | | | | | | | sample_fmt We generate S16 samples and we should allocate the right buffer Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* | examples/muxing: fix av_frame_free() not called when got_packet is falseIlya Basin2013-12-211-1/+2

* | examples/demuxing_decoding: print the decoding error when it happens.Clément Bœsch2013-12-131-2/+2

* | examples/demuxing_decoding: return error when no codec foundEven Wiik Thomassen2013-12-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* examples: demuxing: print ffplay command even if sample format is planarwm42013-07-191-2/+14
| | | | | Adjust the code so that a working ffplay command is printed in the planar audio case.
* examples: demuxing: simplify audio outputwm42013-07-191-36/+10
| | | | | | | | 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.
* examples: demuxing: do partial audio packet decodingwm42013-07-191-3/+16
| | | | | | 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.
* examples/muxing: add support to audio resamplingStefano Sabatini2013-07-061-28/+93
| | | | | Allows to encode to output in case the destination sample format is different from AV_SAMPLE_FMT_S16.
* lavfi: create Libav-API compatibility layer for avfilter_graph_parse() at ↵Stefano Sabatini2013-07-032-2/+2
| | | | | | | | | | | | | | | | | 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.
* examples/muxing: make more compact audio/video_time computationStefano Sabatini2013-07-031-9/+2
|
* examples/muxing: rename audio/video_pts to audio/video_timeStefano Sabatini2013-06-261-8/+8
| | | | | The new name is less confusing, since the variables represent times rather than timestamps.
