| * | Don't use ff_cropTbl[] for IDCT.Ronald S. Bultje2012-03-069-201/+161
| | | | | | | | | | | | | | | | | | | | | | | | Results of IDCT can by far outreach the range of ff_cropTbl[], leading to overreads and potentially crashes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

| | | | | | | | | | | | | | | avcodec_encode_video2() return value is 0 on success, encoded frame size is stored in the packet.

* | | aacdec: Fix out of array writes (stack).Michael Niedermayer2012-03-061-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes an issue in the code to check the size that will be written to match the actual code writing. In the long term it would make sense to change this so the counting and writing code are the same so they dont need to be kept in sync. It also increases the array size, which was too small either way and adds a redudnant saftey check. This issue does not affect any FFmpeg release as it has been introduced Jan 31 which is narrowly after our last release. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | |
| * | amrnb/amrwb: Remove get_bits usage.Alex Converse2012-03-052-16/+4
| | | | | | | | | | | | | | | It is used to parse fixed sized fields out of a single octet. The code is simpler without it.
| * | cosmetics: reindentJustin Ruggles2012-03-051-5/+5

| * | avformat: do not require a pixel/sample format if there is no decoderJustin Ruggles2012-03-052-13/+30
| | | | | | | | | | | | | | | | | | | | | | | | Also, do not keep trying to find and open a decoder in try_decode_frame() if we already tried and failed once. Fixes always searching until max_analyze_duration in avformat_find_stream_info() when demuxing codecs without a decoder.
| * | avformat: do not fill-in audio packet duration in compute_pkt_fields()Justin Ruggles2012-03-051-14/+33
| | | | | | | | | | | | Use the estimated duration only to calculate missing timestamps if needed.
| * | lavf: Use av_get_audio_frame_duration() in get_audio_frame_size()Justin Ruggles2012-03-053-39/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also, do not give AVCodecContext.frame_size priority for muxing. Updated 2 FATE references: dxa-feeble - adds 1 audio frame that is still within 2 seconds as specified by -t 2 in the FATE test wmv8-drm-nodec - durations are not needed. previously they were estimated using the packet size and average bit rate.

| | | | | | | | | | | | It is not necessary

| | | | | | | | | | | | It is not necessary

| | | | | | | | | | | | It is not necessary
| * | siff: do not set AVCodecContext.frame_sizeJustin Ruggles2012-03-051-3/+5
| | | | | | | | | | | | | | | also, properly set AVCodecContext.bits_per_coded_sample, AVStreasm.start_time, and AVPacket.duration.
| * | amr demuxer: do not set AVCodecContext.frame_size.Justin Ruggles2012-03-051-2/+0
| | | | | | | | | | | | it is not necessary.
| * | aiffdec: do not set AVCodecContext.frame_sizeJustin Ruggles2012-03-052-30/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | It is unnecessary. Also, for some codecs we're reading more than 1 frame per packet. Instead we use a private context variable to calculate the bit rate, stream duration, and packet durations. Updated FATE seek test, which has slightly different timestamps due to a more accurate bit rate calculation.
| * | mov: do not set AVCodecContext.frame_sizeJustin Ruggles2012-03-051-13/+0
| | | | | | | | | | | | It is not necessary.
| * | ape: do not set AVCodecContext.frame_size.Justin Ruggles2012-03-051-1/+0
| | | | | | | | | | | | prevents lavf from setting incorrect packet durations.
| * | rdt: remove workaround for infinite loop with aacJustin Ruggles2012-03-051-3/+0
| | | | | | | | | | | | avformat_find_stream_info() no longer hangs while waiting for AAC frame_size
| * | avformat: do not require frame_size in avformat_find_stream_info() for CELTJustin Ruggles2012-03-051-3/+0
| | | | | | | | | | | | | | | In Ogg/CELT, frame_size is found in the same place as the sample_rate and channels, so we do not need to force the frame_size to be parsed.
| * | avformat: do not require frame_size in avformat_find_stream_info() for MP1/2/3Justin Ruggles2012-03-051-3/+0
| | | | | | | | | | | | | | | It was only needed to avoid a bad time base (and thus non-monotone timestamps) for stream copy to avi.
| * | avformat: do not require frame_size in avformat_find_stream_info() for AACJustin Ruggles2012-03-051-1/+0
| | | | | | | | | | | | We already will get the needed info because of CODEC_CAP_CHANNEL_CONF
| * | swfenc: use av_get_audio_frame_duration() instead of AVCodecContext.frame_sizeJustin Ruggles2012-03-051-5/+1
| | | | | | | | | | | | | | | This way we can do stream copy without having the demuxer wait until frame_size has been set.
| * | rtpenc: use av_get_audio_frame_duration() for max_frames_per_packetJustin Ruggles2012-03-051-2/+9
| | | | | | | | | | | | | | | It is more reliable than AVCodecContext.frame_size for codecs with constant packet duration.
| * | riffenc: use av_get_audio_frame_duration()Justin Ruggles2012-03-051-5/+23
| | | | | | | | | | | | | | | | | | For encoding, frame_size is not a reliable indicator of packet duration. Also, we don't want to have to force the demuxer to find frame_size for stream copy to work.
| * | avcodec: add av_get_audio_frame_duration() function.Justin Ruggles2012-03-054-1/+157
| | | | | | | | | | | | | | | This is a utility function for the user to get the frame duration based on the codec id, frame size in bytes, and various AVCodecContext parameters.
| * | avcodec: add av_get_exact_bits_per_sample() functionJustin Ruggles2012-03-052-11/+33
| | | | | | | | | | | | | | | | | | This only returns bits per sample when it is exactly correct. That is, the codec contains only raw samples with no frame headers or padding. This applies to basically all PCM codecs and a small subset of ADPCM codecs.
| * | lavf: deobfuscate read_frame_internal().Anton Khirnov2012-03-056-172/+180
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split off packet parsing into a separate function. Parse full packets at once and store them in a queue, eliminating the need for tracking parsing state in AVStream. The horrible unreadable loop in read_frame_internal() now isn't weirdly ordered and doesn't contain evil gotos, so it should be much easier to understand. compute_pkt_fields() now invents slightly different timestamps for two raw vc1 tests, due to has_b_frames being set a bit later. They shouldn't be more wrong (or right) than previous ones.
| * | lavf: make read_from_packet_buffer() more flexible.Anton Khirnov2012-03-051-12/+20
| | | | | | | | | | | | | | | | | | | | | | | | Make packet buffer a parameter, don't hardcode it to be AVFormatContext.packet_buffer. Also move the function higher in the file, since it will be called from read_frame_internal().
