Andreas Rheinhardt	423b6a7e49	avutil/imgutils: Add wrapper for av_image_copy() to avoid casts av_image_copy() accepts const uint8_t* const * as source; lots of user have uint8_t* const * and therefore either cast (the majority) or copy the array of pointers. This commit changes this by adding a static inline wrapper for av_image_copy() that casts between the two types so that we do not need to add casts everywhere else.

Marton Balint	2296078397	avutil/frame: deprecate AVFrame.coded_picture_number and display_picture_number Their usefulness is questionable, very few decoders set them, and their type should have been int64_t. A replacement field can be added later if a valid use case is found. Signed-off-by: Marton Balint <cus@passwd.hu>	2 years ago

Andreas Cadhalpun	dd6c8575db	examples/demuxing_decoding: use properties from frame instead of video_dec_ctx This is more robust. And only check if there is actually a frame returned.

Andreas Cadhalpun	078be09dd7	examples/demuxing_decoding: abort decoding when width, height or pix_fmt change This is necessary, because avcodec_decode_video2 can change width, height and/or pixel format of the AVCodecContext. Since video_dst_data and video_dst_linesize are not updated by calling av_image_alloc again, av_image_copy[_plane] asserts, because the destination buffer is too small. In this case, creating a useable rawvideo is not possible anyway, since it has fixed width/height/pix_fmt.

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	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
