| | | | | | | | The current size is not enough, see e.g. http://ftp.itec.aau.at/datasets/DASHDataset2014/TearsOfSteel/1sec/TearsOfSteel_1s_simple_2014_05_09.mpd Reviewed-by: Steven Liu <lq@chinaffmpeg.org> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avformat/dashdec: Ensure strings are zero-terminatedAndreas Rheinhardt2021-03-02
| | | | | | | | | | | | | | | | | strncpy only ensures that one does not write beyond the end of the destination buffer; in case of truncation it does not zero-terminate the destination buffer. This makes using it the way it is now in the DASH demuxer dangerous. So use av_strlcpy instead. Also don't write anything if there is no id: The buffer has already been zeroed initially. The DASH testset from the Universität Klagenfurt contains samples with ids that are too long.

* fftools: Switch to const AVCodec * where possibleAndreas Rheinhardt2021-03-02
| | | | | | | | | | | The obstacle to do so was in filter_codec_opts: It uses searches the AVCodec for options via the AV_OPT_SEARCH_FAKE_OBJ method, which requires using a void * that points to a pointer to a const AVClass. When using const AVCodec *, one can not simply use a pointer that points to the AVCodec's pointer to its AVClass, as said pointer is const, too. This is fixed by using a temporary pointer to the AVClass. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avformat/matroskadec: Add support for FlagOriginalAndreas Rheinhardt2021-03-02
| | | | | | | | | | | | | | | | Needs a CountedElement in order to distinguish the case of the element not being present and the element being present with a value of zero. (It has been argued by Ridley Combs that one should only ever use the AV_DISPOSITION_DUB field for audio tracks. Yet given that there is no definition for the disposition flags, one can also interpret it to mean that e.g. a subtitle track is meant to be used with the dubbed audio track or the original audio track. This commit interprets this flag in this sense, which also allows to maintain it on remuxing.)

* avcodec/roqvideo: Use dedicated context for encoderAndreas Rheinhardt2021-03-01
| | | | | | | | | | | Up until now, the RoQ video decoder and encoder used the same context; and said context contained several fields that are only used by the encoder. This commit changes this and uses a dedicated context for the encoder; it contains the common context as first element in order to use functions common to the de- and encoder.

* avcodec/libx264: Don't use init_static_data for newer versionsAndreas Rheinhardt2021-02-28
| | | | | | | | | | | x264 versions >= 153 can support multiple bitdepths; they also don't export x264_bit_depth any more. The actual check whether a bitdepth is supported is therefore performed at runtime in x264_encoder_open. Ergo it is unnecessary to use init_static_data for these versions: One can already set ff_libx264_encoder.pix_fmts to the value that X264_init_static always sets it to.

| | | | | | | | | | | | | | | | | | | | | | | | Memory for auxillary_info was not freed after usage. Leak can be reproduced with following commands: Optionally, generate input video: ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 input.mp4 Run ffmpeg with valgrind: valgrind --leak-check=full --show-leak-kinds=all \ ffmpeg -y -i input.mp4 -vcodec copy -acodec copy \ -encryption_scheme cenc-aes-ctr \ -encryption_key 00000000000000000000000000000000 \ -encryption_kid 00000000000000000000000000000000 \ ffmpeg_encrypted.mp4 For test video which has duration of 10 sec, leak is 4 Kb. For 100 sec video, leak will be 33 Kb. Most likely, leaked memory will grow linearly to the number of input frames.
