* avcodec/xbmenc: Allow for making UW imagesJose Da Silva2021-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've run into some bugs where I was downloading a bunch of data and began seeing weird hiccups. For example, javascript promises to allow you to push some very long lines of data, but the hiccups I saw was with data larger than 2k in length (windows) pushed out of a child process stdout piped into the stdin of the calling parent program. Soo much for smooth promises, this was broken and would run into similar problems on a linux PC with 32k line limits. The solution was to break the data into smaller chunks than 2k - and then these data hiccups disappeared (windows PC). It would be expected to be similar for linux PCs (32k I think) and other OSes with different sizes. If the ANSI required minimum needs to be 509 chars or larger (assuming 509+<CR>+<LF>+<0>=512), then 509 was chosen as the shortest worst-case scenario) in this patch. Most small pictures will go output looking pretty much the same data out until you get to about 84bytes (672 pixels wide), where lines out begin to be split. For example a UW 4K will exceed a 2k readln and a UW 10K picture approaches an 8k readln The purpose for this patch is to ensure that data remains below the readline limits (of 509 chars), so that programs (like javascript) can push data in large chunks without breaking into hiccups because the data length is too long to be pushed cleanly in one go. Subject: [PATCH 3/3] avcodec/xbmenc: Allow for making UW images Worst-case ANSI must allow for 509 chars, while Windows allows for 2048 and Linux for 32K line length. This allows an OS with a small readline access limitation to fetch very wide images (created from ffmpeg).
* avcodec/xbmenc: xbm Lower memory useJose Da Silva2021-01-28
| | | | | | | | | | | | | | | | Two minor memory improvements. First bug reduces memory needed to about 6/7 the needed amount, which allows you to host almost 7 pictures in the same memory needed for 6 Second is a recalculation of the total additional memory for headers etc. size = avctx->height x (linesize * 6 + 1) + (31+32+38+4+1) Subject: [PATCH 2/3] avcodec/xbmenc: xbm Lower memory use Small 6/7th size memory reduction. size = avctx->height x (linesize * 6 + 1) + (31+32+38+4+1) Signed-off-by: Joe Da Silva <digital@joescat.com>
* avcodec/xbmenc: Do not add last comma into outputJose Da Silva2021-01-28
| | | | | | | | | | | | | | | | | | | | | | There is a minor bug in xbm encode which adds a trailing comma at the end of data. This isn't a big problem, but it would be nicer to be more technically true to an array of data (by not including the last comma). This bug fixes the output from something like this (having 4 values): static unsigned char image_bits[] = { 0x00, 0x11, 0x22, } to C code that looks like this instead (having 3 values): static unsigned char image_bits[] = { 0x00, 0x11, 0x22 } which is the intended results. Subject: [PATCH 1/3] avcodec/xbmenc: Do not add last comma into output array xbm outputs c arrays of data. Including a comma at the end means there is another value to be added. This bug fix changes something like this: static unsigned char image_bits[] = { 0x00, 0x11, 0x22, } to C code like this: static unsigned char image_bits[] = { 0x00, 0x11, 0x22 } Signed-off-by: Joe Da Silva <digital@joescat.com>
* avcodec/flashsv2enc: Fix use of uninitialized valueAndreas Rheinhardt2021-01-28
| | | | | | | | | | | | | | Before 257a83b969157eb76c18158a4e503e908d8b1125, certain buffers were zero-allocated in the init function and only reallocated lateron if they turned out to be too small; now they are only allocated during init, leading to use-of-uninitialized values lateron. The same could happen before if the dimensions are big enough so that the buffers would be reallocated, as the new part of the reallocated buffer would not be zeroed (happened for 960x960). So always zero the buffers in the function designed to init them. Reviewed-by: Marton Balint <cus@passwd.hu> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* Revert "mpeg4videodec: raise an error if sprite_trajectory.table is NULL"Andreas Rheinhardt2021-01-27
| | | | | | | | | | | | | | | | | | | | This reverts commit 6ac0e7818399a57e4684202bac79f35b3561ad1e. The mpeg4video parser can reach code that presumes that a certain VLC has been initialized; yet Libav did not ensure this and Libav bug #1012 [1] is about an ensuing crash. Instead of fixing the root cause a simple check for whether said VLC has already been initialized was added; said check is inherently racy. The proper fix is of course to ensure that the VLC is initialized and commit 7c76eaeca2791261d3f4f5c98c95f44abdbd879a already ensured this, so there was no need to merge 6ac0e7818399a57e4684202bac79f35b3561ad1e at all. This commit therefore reverts said commit. [1]: https://bugzilla.libav.org/show_bug.cgi?id=1012 Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
