#9535: PNG decoder fails processing more than a certain number of frames -------------------------------------+------------------------------------- Reporter: panthalassa | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: png | Blocked By: decoding | Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: trying to encode a video with more than a certain number of frames from a .png sequence results in corrupted output and an out-of-memory scenario How to reproduce: Sorry but due to the absurd bandwith requirements I likely won't be able to upload the offending files. This can likely be reproduced by converting a long, losslessly compressed video into a sufficient number of PNG's (my stats: 11 minute 1080p video at 60fps = ~39,000 frames, each frame 1.9mb making the uncompressed video around 80gb) I acquired these frames from rendering in Blender Present on all versions I've tested from 3.4.8 to 4.4.1. Any png-based input fails with too many files in the directory - symptoms include the encoded video having scrambled frame order after about 1000 frames, as well as the [png @ 0x??? chunk too big] error after about 14750 processed frames. Taking a generous swathe of images around the error points and processing them separately produces no errors implying that a corrupted PNG is not to blame. Putting a smaller (1-2000) number of frames in a directory and processing them separately produces a successful result longer than 1000 frames, past the previous point of onset for corruption. Unknown exactly how many frames are needed to cause the error. Any format encoding that receiving raw PNG input appears to be bugged - libx264rgb, libx265, ffv1 tested Latest tested version: clean install of N-104671-g2cddb2f7a8 on a live USB of Linux Mint 19.1 MATE following the instructions on the Compile FFMPEG page {{{ % ffmpeg -framerate 60 -f image2 -pattern_type glob -i $1'/*.png' -vcodec libx265 -pix_fmt yuv420p10le -vf scale=out_range=pc $2 % ffmpeg -framerate 60 -f image2 -pattern_type glob -i $1'/*.png' -vcodec ffv1 -coder 1 -level 3 -threads 4 -slices 4 -pix_fmt bgra $2 ffmpeg version: N-104671-g2cddb2f7a8 built on ...

Even if you just re-opening the format context to accomplish this with the 'live_start_index' avdict option you don't have the information of the segments/durations. Additionally, it seems that the hls demuxer sets AVFMTCTX_UNSEEKABLE flag always. Can't see the reason why it applies it for example in this HLS live stream (https://cph-p2p- msl.akamaized.net/hls/live/2000341/test/level_3.m3u8) It has been also seen even after seeking on HLS live stream that the timestamps are not related to the previous ones (before seeking) or to the first_timestamp or ic->start_time. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9357> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
