* avformat/evcdec: Avoid nonsense castsAndreas Rheinhardt2023-07-071-3/+3
| | | | | | | | | | | | | For uint8_t buf[EVC_NALU_LENGTH_PREFIX_SIZE], &buf still points to the beginning of buf, but it is of type "pointer to array of EVC_NALU_LENGTH_PREFIX_SIZE uint8_t" (i.e. pointer arithmetic would operate on blocks of size EVC_NALU_LENGTH_PREFIX_SIZE). This is of course a different type than uint8_t*, which is why there have been casts in evc_read_packet(). But these are unnecessary if one justs removes the unnecessary address-of operator.

* avformat/mov: fix overallocation when reading pssh/saizZhao Zhili2023-06-241-38/+25
| | | | | | | | | | | | | | | | | | | | | | | | mov_try_read_block() allocates 1MB at least, which can be more than enough. It was called when reading saiz box, which can appear periodically inside fmp4. This consumes a lot of memory. We can fix mov_try_read_block() by clamp 'block_size' with 'size'. However, the function is harmful than helpful. It avoids allocating large memory when the real data is small. Even in that case, if allocating large memory directly failed, it's fine to return ENOMEM; if allocating success and reading doesn't match the given size, it's fine to free and return AVERROR_INVALIDDATA. In other cases, it's a waste of CPU and memory. So I decided to remove the function, and replace it by call av_malloc() and avio_read() directly. mov_read_saiz() and mov_read_pssh() need more check, but they don't belong to this patch. Fixes #7641 and #9243. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>

* libavformat/mpegts.c: fix hardcoded 5-bytes skip for metadata streams.Romain Beauxis2023-06-201-1/+1
| | | | | | | | | | | | | | | | | | | Before the introduction of AV_CODEC_ID_TIMED_ID3 for timed_id3 metadata streams in mpegts (commit 4a4437c0fbc8f7afe0c533070395a42e56b4ee75), AV_CODEC_ID_SMPTE_KLV was the only existing codec for metadata. It seems that this codec has a 5-bytes metadata header[1] that, for some reason, was always skipped when decoding data packets. However, when working with a AV_CODEC_ID_TIMED_ID3 streams, this results in the 5 first bytes of the payload being cut-off, which includes essential informations such as the ID3 tag version. This patch fixes the issue by keeping the 5-bytes skip only for AV_CODEC_ID_SMPTE_KLV streams. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>

* lavf/rtpenc_jpeg: Retrieve sampling factor from SOF0Yeoh, Hoong Tee2023-06-201-15/+26
| | | | | | | | | | | | In ff_rtp_send_jpeg, the type is defined based on PIX_FMT and color-range parsed in. There is limitation on current design where need to include support newly introduced PIX_FMT such as AV_PIX_FMT_QSV and there might be more and more in future. Hence, retrive the sampling factor from SOF0 in JPEG compressed header directly. This introduces flexibility to handle different type of new codec introduced in future.
