TargetTypeValue to group metadata tags by object: 50 = Album object 30 = Track object FFmpeg is only returning TargetTypeValue = 30 (track info) Kodi 18/19 is using ffmpeg to read Matroska metadata and need the album tags (TargetTypeValue = 50) as well as curennt track tags.

#7986(avformat:new): Initial EXT-X-PROGRAM-DATE-TIME rounded to integer

#7094(avformat:new): Assertion in AVIO fill_buffer

#7094: Assertion in AVIO fill_buffer -------------------------------------+------------------------------------- Reporter: redeemarr | Type: defect Status: new | Priority: normal Component: avformat | Version: git- Keywords: avio, | master abort, crash | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- It happens sometimes while demuxing mpegts stream using custom IO operations via AVIOContext, assertion fails in function 'fill_buffer' in aviobuf.c: av_assert0(len >= s->orig_buffer_size); Seems like something goes wrong when AVIOContext decides to reduce it's internal buffer size. This issue can be easily reproduced in my case, when AVFormatContext.probesize equals initial buffer size for AVIOContext. Sample code to reproduce: {{{#!c++ int read_handler(void* opaque, uint8_t* dst, int dst_size) { bytes_t* input = (bytes_t*)opaque; size_t available = input->size(); size_t size = available < dst_size ? available : dst_size; if (size > 0) { memcpy(dst, input->data(), size); input->erase(input->begin(), input->begin() + size); } return size > 0 ? size : AVERROR_EOF; } void test_avio(char const* path) { std::ifstream ifs(path, std::ios::binary); ifs.seekg(0, std::ios::end); size_t size = ifs.tellg(); ifs.seekg(0, std::ios::beg); std::vector<char> input(size); ifs.read(input.data(), input.size()); AVInputFormat* m_format = av_find_input_format("mpegts"); AVFormatContext* m_fc = avformat_alloc_context(); size_t buffer_size = 16 * 1024; uint8_t* avio_buffer = (uint8_t*)av_malloc(buffer_size + FF_INPUT_BUFFER_PADDING_SIZE); m_fc = avformat_alloc_context(); m_fc->probesize = buffer_size; m_fc->pb = avio_alloc_context(avio_buffer, buffer_size, 0, &input, &read_handler, NULL, NULL); m_fc->pb->seekable = 0; m_fc->pb->write_flag = 0; int err = avformat_open_input(&m_fc, NULL, m_format, NULL); err = avformat_find_stream_info(m_fc, NULL); // In this case it fails even at this point // ... } }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/7094> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
